    Opis:
    The world’s noticeable population growth is associated with an increased demand for agricultural products. The search for new solutions to increase crop productivity while ensuring environmental stability is becoming a key role. One such method is the use of the biopreparations containing Effective Microorganisms. EM consist of about 80 species of selected aerobic and anaerobic microorganisms, which have the ability to restore the biological balance. Professor Teruo Higa of Ryukyus University in Okinawa is the creator of Effective Microorganisms. When added to agricultural ecosystems they stimulate plant growth, improve the condition of soils affected by excessive use of chemical fertilizers allowing insoluble forms of elements to be transformed into plant-available forms and protect them from certain diseases and pests. This solution is an ecological alternative to conventional technologies and does not further pollute the ecosystem, which is crucial. Organic fertilizers in the form of EMs are made using live microorganisms they do not only deliver nutrients to the soil but also allow inactive ones to become available. With improved nutrient uptake and protection from soil pathogens, plants develop and grow better for improved yields. They contain organic matter and one or more biologically active organic compounds (amino acids, vitamins) as well as macroand microelements that stimulate plant growth and development. They provide plants with essential substances, which are naturally synthesized in many complex biochemical processes, causing energy savings that can be used for other transformations in the plant.

    Opis:
    Applying vermicomposting process for sewage sludge treatment is a low-cost method which has been gaining a growing number of supporters around the world. In Poland it is still rather unpopular method. The following publication presents the results of 12 years (2004–2015) of research and experiments on the use of red Californian earthworm in Wastewater Treatment Plant in Zambrów. Among others, the results of analyzing vermicompost quality were shown concerning selected micro and macro elements, fertilizing value and sanitary condition. Cumulative content of the examined heavy metals was highest in 2004 and reached over 1200 mg-1 kg s.m., whereas the lowest content of 520 mg-1 kg s.m. was observed in 2012. The study results indicate that in the entire 12-year research period vermicompost met the standards for organic-mineral fertilizers, which means it contained over 20% of organic substance in reference to dry mass and over 1% of total nitrogen and 0.5% of phosphorous in reference to phosphorus pentoxide (P2O5). During the entire research period no living eggs of intestinal parasites Ascaris sp., Trichuris sp., Toxocara sp. and Salmonella bacteria were observed in the vermicompost. The research concerning red Californian earthworm proved substantial mineralization and humification of sludge. The application of EM formula considerably quickened the process and the achieved modifications in the vermicompost structure and content.

    Opis:
    Air temperature is one of major factors in a subjective assessment of human thermal comfort and discomfort. The work draws on a series of measurements of the average daily air temperatures, relative air humidity and wind speed for 2000-2016 recorded at the Siedlce Meteorological Station. The station is part of the state observation and measurement network of the hydrological and meteorological service of The Institute of Meteorology and Water Management – National Research Institute (IMGW-PIB). The effective temperature was calculated according to the formula recommended by Missenard and the thermal sensation was determined based on a scale suggested by Baranowska. The number of days with individual thermal sensations in individual months of the long-term period was calculated, and months were put into groups of similar sensations by means of principal component analysis (PCA) and cluster analysis. In the last years (2015, 2014, 2012 and 2011) in the months representing the cold season of the year, there were more days which were very cold and cold, whereas the number of days with the thermal comfort was much lower. The long-term period was split into three groups, based on the thermal comfort in the warm season of the year. The years which formed one group included 2011, 2013, 2015 and 2016 when there were no very cold days, the least cold days and the most very hot days.

    Opis:
    The paper presents the results of research on the use of sewage sludge from the municipal sewage treatment plant in Białystok for fertilization of urban lawns. To fertilize the ground two types of deposits were used: stabilized sludge after the dewatering process in the press and granular sludge after drying in the sludge dryer. Two doses of sludge were used – 5 and 10 kg/m2. Effective microorganisms (EM) were added to the test plots. Both doses of the applied sewage sludge contributed significantly to the growth of grass biomass. Aboveground biomass of the plants was significantly correlated with the concentration of Cd, Cu, Pb and Zn in the surface layer of the soil. The addition of EM to soil containing the dewatered sludge from the press reduced significantly the content of heavy metals in the soil, as opposed to the sludge in a form of granules with addition of EM, which contributed to the increase of their concentration in the soil.

    Opis:
    A detailed hydrologic analysis was performed using geographic information systems and field investigations for thirty residential quarters in the Franko district of the Lviv city, Ukraine. All investigated quarters are located at the territory of the Baltic Sea catchment of the Lviv city, and the surface runoff from this area flows to the Lviv wastewater treatment plant. The total area of the investigated sub-catchment is 348.5 ha, including 58.46 % of impervious covers, 41.17 % of green spaces and 0.37 % of water bodies. The share of total impervious surfaces for each of the 30 analyzed quarters varies from 0.329 to 0.929, and the effective imperviousness – from 0.222 to 0.917. The correlation between the total and effective imperviousness was described by the power law dependency pef=(ptot) n. Two approaches were used to describe the relationship between the total and the effective imperviousness: 1) using all 30 empirical results for each quarter; 2) using the average values of the imperviousness of the total subcatchment. The obtained values of the power law exponent for these two empirical approaches are n1=1.308 and n2=1.275, respectively or 7.2 % and 9.6 % less, respectively, comparing to the corresponding value n=1.41 in the Livingston’s & Veenhuis’ approximation, obtained for 14 different highly urbanized quarters of Denver city. On the other hand, the power law exponents are 3.9% and 1.3% higher, respectively, comparing to the corresponding value n=1.259 in the approximation for the 900 km2 semi-urban watershed in Marion County, Georgia, USA.

    Opis:
    Improperly treated heavy metal wastewater discharged into water sources could cause a serious issue for the environment. The aim of this study was to bioaccumulate iron (Fe) using native bacteria isolated from the laboratory drainage water containing a high concentration of iron. The experiment was conducted in 250 mL conical flasks containing 150 mL Fe solution in concentrations of 25, 100, and 250 mg/L, respectively. Approximately 10% of bacteria inoculum was cultivated in each Fe concentration for 24 and 48 hours. The results showed that Pseudomonas hibiscicola was identified as an effective iron-accumulating species of bacteria. The species could remove Fe up to 82% (25 mg/L), 77.8% (100 mg/L) and 32% (250 mg/L). This promising result indicates that the native bacteria isolated from the environment pose a great potential for the remediation of wastewater containing iron.

    Opis:
    The purpose of the research was to synthesize new effective and cheap coagulants from industrial wastes (red mud) and study their coagulation properties on model water of textile industries, as well as develop a closed scheme of local wastewater treatment using the synthesized coagulants. Liquid coagulants, synthesized with the simple method, have better performance than commercial FeCl3, since not only iron but also aluminum and titanium compounds are present in the synthesized liquid coagulants, which makes them more effective. For the synthesized coagulants with a dose of 10 mg/l, the removal efficiency of the dyes mixture from the water was 99.7%, while for the commercial FeCl3, with a 2.5 times higher dose – only 95.4%. In the case of creating closed scheme of treatment and usage of the treated water with the coagulation method, an additional sorption purification step from the trace concentrations of pollutants was proposed. The usage of the new coagulants, synthesized from the wastes of alumina production in the proposed scheme will not only help reduce the environmental burden by minimizing the wastewater discharges into sewerage, but also recycle the accumulated environmentally hazardous “red mud” waste into commercial products.

    Bisphenol A (BPA) is widely used in everyday life and can be found everywhere, including in the ecosystem and manufactured goods. BPA not only has a negative impact in low doses, but it also has biological and pathophysiological implications for obesity and hormonal effects. The objectives of this paper were to review the BPA removal technology and the factors that influence the BPA removal based on biological methods. BPA elimination from water is crucial for environmental protection, in terms of biological treatment. In addition, the future prospect of biological removal of BPA indicates that effective microorganism cultures could disturb the pathogen growth and increase composition rate of BPA. The biological technology by the implementation of microorganisms for the removal of BPA through break down of organic contaminants is straightforward, money saving, and widely acknowledged by the public.

    Opis:
    The present paper was aimed at determining the influence of particular methods and biological processes, including the application of Effective Microorganisms, on the change in characteristics of the treated dairy sewage sludge, especially when discussing the changes in the content of nutrients and macroelements. The purpose of the conducted research was to specify the possibility of using natural biological methods of dairy sewage sludge treatment and adapting it to environmental, especially farming use. Diagnostic research on the content of sewage sludge from dairy wastewater treatment plants in the north-eastern region of Poland has been conducted since the 1990s. On the basis of the results and the assessment of the possibility of agricultural utilization of dairy sewage sludge, the objectives for research on sludge treatment were established. The research facilities were located on the premises of Municipal Wastewater Treatment Plant in Zambrów. The choice of location for the research facilities was guided by the possibility of supplying the same sludge from dairy wastewater treatment. The excess sludge from biological dairy sewage treatment, which was aerobically stabilized in separate chambers, was used in the research. In all of the facilities where sludge was treated with biological methods, Effective Microorganisms (EM) were also used for comparison. In the years 2010-2013, the research was conducted in the research facilities (own project) constructed and launched in 2010, which were planted with phragmites and common osier. In the years 2010-2012, the research was conducted in the research facilities (own project) constructed and launched in 2010, i.e. vermiculture patches. The conducted research was comprehensive and the obtained experiment results point to the necessity of continuation and further development of research concerning the content transformation in dairy sewage sludge during its biological treatment. Establishing the role of microorganisms present in the EM formula on the processes and transformations occurring in biologically treated sewage seems to be of exceptional importance. The innovativeness of the research lay mainly in a very comprehensive range of natural biological methods of treatment applied for the same sewage sludge coming from dairy wastewater treatment plants. The conducted research points to the influence of the EM formula on vital changes in the content of macroelements in the biologically treated dairy sewage sludge. The most important impact (from the point of view of the number of parameters and the change in size as a result of applying EM formula) was observed in reference to the vermicomposting process with the use of earthworms and long-term stabilization in reed beds. The statistical assessment methods applied to the obtained results of own research (Wilcoxon and Spearman tests, Spearman’s rank correlation coefficient) point to a significant influence of the EM formula on different “behavior” of many analyzed characteristics of the treated sludge.

    Opis:
    Problem z właściwym zagospodarowaniem gnojowicy obecny jest przede wszystkim podczas intensywnej produkcji zwierzęcej. Uprzemysłowione fermy zwierząt gospodarskich generują ogromne ilości odchodów w postaci gnojowicy w bezściółkowym systemie utrzymania zwierząt. Tradycyjne zagospodarowanie gnojowicy odbywa się poprzez wykorzystanie jej jako nawozu naturalnego. Alternatywne techniki wykorzystywane w celu zneutralizowania szkodliwego wpływu gnojowicy opierają się na stosowaniu dodatków chemicznych i biologicznych, a także poprzez wprowadzenie środowiska tlenowego przez napowietrzanie lub beztlenowego, prowadząc fermentację metanową. W przeprowadzonym doświadczeniu wykorzystano gnojowicę bydlęcą, która pochodziła z gospodarstwa Przybroda należącego do Uniwersytetu Przyrodniczego w Poznaniu. Celem badań było określenie wydajności biogazowej gnojowicy z zastosowaniem dodatku chemicznego i biologicznego dostępnego na polskim rynku. Dla wskazania skuteczności zastosowanego procesu fermentacji wykorzystano fermentację mezofilową oraz termofilową. Dodatkowo do badanej gnojowicy zastosowano dodatek biologiczny – Efektywne Mikroorganizmy oraz chemiczny – PRP. Przeprowadzone doświadczenie wykazało wyższą wydajność biogazową podczas zastosowania Efektywnych Mikroorganizmów.
    The problem of proper slurry management is primarily present in intensive livestock production. Industrialized livestock farms generate enormous quantities of manure droppings in a livestock-litter-free system. The traditional management of slurry is made by using it as a fertilizer. Alternative techniques used for neutralizing the detrimental effect of slurry are based on the use of chemical and biological additives, as well as by introducing aerobic environment through aerobic or anaerobic digestion, leading to methane fermentation. In the experiment, cattle manure was used, which came from the Przybroda farm belonging to the University of Life Sciences in Poznan. The aim of the study was to determine the biogas yield of slurry using the chemical and biological additive available on the Polish market. Mesophilic and thermophilic fermentation was used for the indication of the effectiveness of the employed fermentation process. The slurry was supplemented by a biological and chemical additive, i.e. Effective Microorganisms and – PRP, respectively. The experiment allowed to achieve a higher biogas yield during the use of Effective Microorganisms.

The expediency of implementing a particular technology was determined by selecting the best ones from the point of view of environmental, economic and social aspects. The waste re-use is the second most acceptable technology, after waste prevention or minimization during production. This scientific work is dedicated to the waste re-use in food production. The article presents the results of the research and development of the technologies involving the use of organic waste – pomace of the juice production from Chaenomeles fruits. It was determined that the vegetable waste occupies a significant place among the total amount of food waste. The ways of using the waste from the production of Chaenomeles juice was developed and analyzed, which involve obtaining extract, gelling agent, powder, and the ways of their use in the technology of flour-based products were proposed. It was determined that the use of the powder from the pomace of Chaenomeles is the most effective, which allows not only the maximum use of raw materials, but also to improve the technology of production of flour-based products, shorten the fermentation process, extend the shelf life of the finished products and increase their biological value.

    The development of the infrastructure of the oil and gas complex is one of the most significant factors of negative impact on the environment. The most efficient way to drill wells is cluster drilling, which currently accounts for 95% of all operations carried out in fields. In the process of oil and oil products production, toxic drilling waste is generated at the well pad, which is then placed in sludge pits (sludge storage). The aim of the study was to select the methods for drilling waste utilization based on the results of environmental radiation analysis. Within the framework of the study, the following tasks were solved: radiation monitoring of drilling waste was carried out at the “Progress-2000” spectrometric complex; analyzed the physical and chemical composition of drill cuttings; a comparative analysis of the samples under study was carried out in accordance with the normative indicators; methods of utilization of drilling waste are proposed.

Metody niskonakładowe są tu rozumiane, jako metody charakteryzujące się:prostą konstrukcją i technologią, łatwością obsługi, wykorzystaniem naturalnych procesów zachodzących w środowisku, stosowaniem urządzeń technologicznych i technicznych w niewielkim stopniu, niezawodnością działania, nieznaczną kontrolą w trakcie trwania procesu, niewielkim udziałem energii elektrycznej, niskimi kosztami inwestycyjnymi i eksploatacyjnymi. W badaniach poddano ocenie kilka instalacji stosujących: kompostowanie, hydrofity oraz wermi kulturę do przetwarzania osadów ściekowych. Dokonano analizy porównawczej sposobu prowadzenia procesu przetwarzania osadów pod względem technicznym i technologicznym oraz jego skuteczności. Wykorzystano badania i obserwacje własne prowadzone na oczyszczalni ścieków w Sokółce, Zambrowie, Kolnie, Nowej Wsi Ełckiej z ostatnich kilku lat. Najdłuższy czas przetwarzania osadów ściekowych uzyskano w lagunach trzcinowych w Zambrowie i wynosi on 12 lat, natomiast zastosowanie wermikultury trwa dwa lata. W pozostałych analizowanych oczyszczalniach, gdzie stosowano proces kompostowania, całkowity czas przetworzenia osadów ściekowych był podobny i wynosił od około 150 do 180 dni. Zaprezentowano również wybrane wyniki badań własnych dotyczących intensyfikacji niskonakładowych metod przeróbki osadów ściekowych z zastosowaniem Efektywnych Mikroorganizmów.
    The paper presented the experience of several years of research and observation of the sewage treatment systems using low-input ways of processing sewage sludge. Low-cost input methods are here understood as a method which is characterized by simple construction and technology, ease of use, use of natural environmental processes, the use of technological equipment and little technical, operational reliability, a small control during the process, a small share of electricity, low capital and operational costs. The studies were evaluated using several installations: composting, wermikulturęhydrofity and processing of sewage sludge. A comparative analysis method of sewage treatment process in terms of technical and technological as well as its effectiveness. Used their own studies and observations conducted at wastewater treatment plants In Sokolka, Zambrów, Kolno, New Rural Ełk the past few years. The longest processing time of sewage sludge was obtained in the lagoons and reed inZambrów it amounts to 12 years, while the use of wermikultury two years. The otheranalyzed treatment, where the composting process used, the total time of processingsewage sludge was similar and ranged from about 150 to 180 days.Also presented some results of the study on low-input intensification of sludge treatment using Effective Microorganisms.

    Opis:
    Struktura rolno-leśnej przestrzeni w Polsce jest wadliwa, zwłaszcza w środkowo-wschodniej jej części. Przejawia się to najbardziej na tle struktury pokrywy glebowej. Nawet najsłabszej jakości gleby piaskowe tworzą całkiem dobre siedliska leśne, podczas gdy w polowym i pastwiskowym użytkowaniu łatwo przeobrażają się w ruchome piaski. Bardzo niski poziom efektywności biologicznej najsłabszych gleb piaskowych sprawia, ze produkcja roślinna znajduje się już obecnie poniżej granicy ekonomicznej efektywności. W miarę modernizacji technologii i pomniejszania kosztów produkcji roślinnej, uprawa najsłabszych gleb pisakowych staje się zupełnie nieopłacalna. Wyróżniono kryteria oceny potrzeby zwiększenia lesistości – glebowe, ekonomiczne i rekreacyjne. Na podstawie wskaźników waloryzacji rolniczej przestrzeni produkcyjnej oraz lesistości w roku 1980 wyliczono procentowy niedobór lasów w gminach, który przedstawiono na mapie Polski w skali 1:1000000. Porównanie lesistości oraz jej niedoboru w roku 1980 z lesistością w roku 2016 dowodzi jednoznacznie, że lesistość wzrosła bardziej na obszarach o dużej i bardzo dużej lesistości, a w najmniejszym stopniu na obszarach o dużym i bardzo dużym niedoborze lasu, zwłaszcza w województwach łódzkim, lubelskim, mazowieckim i kujawsko-pomorskim.
    The structure of the agro-forest space in Poland is defective, especially in the central and eastern part of the country. This is visible, in particular, in the case of soil cover structure. Even the weakest quality sandy soils provide conditions to create quite good forest habitats, whereas under farm use they are easily transformed into moving sands. The very low level of biological effectiveness of the weakest sandy soils means that plant production is already below the limit of economic efficiency. As technology has been modernized and plant production costs reduced, cultivation of the poorest sand soils will become completely unprofitable. The criteria for assessing the need to increase forest cover can be built upon soil, economical and recreational reasons. On the basis of the indicators for valorizing the agricultural production space and forest cover in 1980, the percentage deficit of forest cover by municipality was calculated and presented in the map of Poland, in the scale of 1: 1,000,000. The comparison of forest cover and its deficit in 1980 with forest cover in 2016 clearly proves that the forest cover has increased more in the areas with high and very high forest cover, and to a lesser extent in the regions having high and very high forest deficit, especially in Łódzkie, Lubelskie, Mazowieckie and Kujawsko- Pomorskie provinces.
