Opis:
One of the greatest environmental problems of modern countries is the pollution of territories with waste. Of particular concern are the wastes generated during the treatment of municipal wastewater, i.e. sewage sludge. They are the inevitable price of urbanization and improved quality of life. As a result of the research conducted, a comprehensive analysis of the composition of municipal sewage sludge was conducted using the example of four small settlements in East Kazakhstan. The results of laboratory studies established the composition of the organic part, biogenic elements, as well as microbiological and parasitological indicators. It was revealed that cadmium, copper, zinc and arsenic are main sources of problems in wastewater treatment plant sludge. For copper and zinc, the standards set by the European Directive 86/278/EEC were exceeded by up to 3.2 and 1.5 times, respectively. At the same time, there is an increased content of nutrients. Organic matter in all studied samples exceeds the minimum established values by 3.5–3.7 times; the potassium content in all studied samples is 5.1–5.6 times higher than the minimum established value for organomineral fertilizers in the Republic of Kazakhstan. The concentration of hydrogen ions (pH) corresponds to neutral. Tests for the determination of microbiological and parasitological parameters indicate that the studied sludge does not contain various pathogenic bacteria and microorganisms.

Opis:
Used in practice biological wastewater treatment systems under aerobic conditions are characterized by high energy consumption and a significant sewage sludge production. Anaerobic wastewater treatment differs from conventional aerobic treatment. The absence of oxygen leads to controlled conversion of complex organic pollutions, mainly to carbon dioxide and methane. Anaerobic treatment has favourable effects like removal of higher organic loading, low sludge production, high pathogen removal, biogas gas production and low energy consumption. Psychrophilic anaerobic treatment can be an attractive option to conventional anaerobic digestion for municipal sewage (and wastewaters with industrial effluents) that are discharged at moderate to low temperature. Most reactions in the biodegradation of organic matter require more energy to proceed at low temperatures than at a temperature optimum of 37ºC. However, same reactions, such hydrogenotrophic methane production, acetate formation from hydrogen and bicarbonate, require less energy. In this work, an upflow anaerobic filter for municipal sewage treatment was used. The investigations were carried out in laboratory scale. The sewage treatment process was operated in psychrophilic conditions in the temperature 15-19°C. The value of hydraulic retention time in anaerobic bioreactor was 48 h. A real municipal sewage was taken from the treatment plant, operated in a full scale. The COD values of raw sewage were between 380 and 895 mg O2/L. The sewage used was additionally polluted with ammonia nitrogen average 81 mg NH4+/L, phosphate - 27 mg PO43-/L as well as sulphates 69 mg SO42-/L. The investigations comprised of three series of different organic loading rates: series 1 - 0.19 kg COD/(m3·d), series 2 - 0.32 kg COD/(m3·d) and series 3 0.26 kg COD/(m3·d). Depending on values of sewage/organic loading rates 46-72% of COD were removal at psychrophilic conditions. The presence of ammonia nitrogen and sulphates did not have a negative impact on the process of organic matter degradation. Anaerobic treatment was effective in removing biodegradable organic compounds, but mineral compounds (NH4+, PO43-, S2-) remained in high concentrations. Therefore, these compounds require removing by an additional post-treatment step.

Opis:
Barbotage reactors extensively used in various branches of industry and bioengineering have been investigated in numerous studies. Recently the moving bed has become a popular solution in sewage and water treatment processes. Purification and transportation of small amounts of sewage from households and industrial plants is a hydraulic and technological problem for the sewage system and sewage treatment plants. A hybrid barbotage reactor (HBR) may be applied to transport small wastewater volumes while simultaneously aerating sewage. This study was conducted on a prototype hybrid barbotage reactor equipped with a pipe element for sewage circulation and aeration, which was packed with a moving bed to 20% of its volume. Based on the results of measurements, oxidation curves have been plotted and the efficiencies of sewage treatment have been calculated for the reactor aerated in the continuous and intermittent modes. The amount of energy used to treat and transport sewage has been established.

Opis:
The sewage flowing into the wastewater treatment plant through the sewer system, as well as transported by the slurry fleet, are subjected to treatment processes. These processes, carried out under both aerobic and anaerobic conditions, contribute to the emission of greenhouse gases. On the basis of available reports and previous research, the emission of nitrous oxide (N2O) from wastewater was estimated at approx. 4-5% in relation to the global amount of this gas emission from anthropogenic sources. Data obtained from the operation of full-scale WWTPs show a wide range of values of the N2O emission factors from 0.0006 to 0.045 (kgN2O-N/kgN). The article describes possible sources of nitrous oxide emission from wastewater treatment plants and presents the basic principles of its balancing.

Opis:
This study aimed to perform a qualitative and a quantitative assessment of the prevalence of genes encoding resistance to beta-lactam, tetracycline, and chloramphenicol antibiotics in samples of DNA isolated from air in a municipal wastewater treatment plant (WWTP) and a municipal waste management plant (WMP). Air samples were collected in the mechanical (MP) and biological (BP) processing units of WWTP and WMP in winter and spring. The samples of air were collected by impingement into PBS solution and subsequently, DNA was isolated. The prevalence of the 16S rRNA gene and ARGs was determined by PCR, and the most abundant ARGs were quantified by qPCR. The highest diversity of the analyzed ARGs was noted in air samples collected in the mechanical processing units of the WWTP (winter) and the WMP (spring). The copy of ARGs varied between treatment units and seasons. ARGs were most abundant in air samples collected in spring in the MP units of both the WWTP and the WMP. The study demonstrated that ARGs are ubiquitous in the air in both WWTPs and WMPs. The presence of ARGs in the air can exert a negative impact on the health of plant employees.

Opis:
The management of sewage sludge, generated at various stages of wastewater treatment, is still a significant problem. One of the possibilities of using sewage sludge, which is a valuable source of nutrients (carbon, nitrogen, phosphorus), is its use for agricultural purposes. Sludge can be used for fertilising when it meets the requirements with regard to the content of heavy metals, the number of eggs of intestinal parasites and Salmonella bacteria, and when the amount of organic substances and fertilising components is sufficient. That is why it is so important to know exactly the characteristics of sewage sludge. This allows determination of whether it can be used as fertiliser in agriculture. The study assesses the agricultural use of sewage sludge from three mechanical and biological wastewater treatment plants of different PE, produced in 2016-2018. The analysis was carried out on the basis of the physicochemical parameters of the sludge. Particular attention was paid to the fertilisation and sanitary properties, as well as the presence of heavy metals, which were largely influenced by such factors as: the size of the wastewater treatment plant, the method of sewage sludge treatment and sludge management, and the nature of the catchment area. The concentrations of particular substances in sludge from wastewater treatment plants differed from one another, and sometimes these were very large differences. The conducted analysis showed that sewage sludge, from both small and large wastewater treatment plants, has a significant potential as agricultural fertiliser due to the presence of minerals such as nitrogen, phosphorus and calcium.

Opis:
The paper presents the results of a study of parameters used for determining the amount of organic pollutants in wastewater flowing into a collective wastewater treatment plant with a population equivalent of about 120 000 PE. The plant constituted part of a sewage system. Assays were performed for biochemical oxygen demand (BOD5), chemical oxygen demand (CODCr), permanganete index (CODMn) and total organic carbon (TOC). In addition, the pH of wastewater and its alkalinity were determined. Sampling of incoming wastewater and measurement of physicochemical parameters were performed once a week, in the spring. A total of 44 samples of wastewater were collected. The correlations between the individual parameters and the correlations between the ratios of these parameters were determined. It was found that it was possible to estimate, with sufficient accuracy, the values of selected parameters for determining the concentrations of organic compounds in municipal wastewater, knowing the values of other parameters in this group. Moreover, it was shown that, knowing the relationship between the analyzed parameters, one can find multiple regression equations for a given type of wastewater, which allow one to calculate the remaining relationships with a good fi t, i.e. a determination factor R2 greater than 0.6.
W pracy przedstawiono wyniki badań parametrów wykorzystywanych do oznaczania ilości zanieczyszczeń organicznych w ściekach wpływających do zbiorczej oczyszczalni ścieków o równoważnej liczbie ludności około 120 000 mieszkańców. Zakład stanowi część systemu kanalizacyjnego. Testy przeprowadzono dla biochemicznego zapotrzebowania na tlen (BZT5), chemicznego zapotrzebowania na tlen (CODCr), utlenialności (CODMn) i ogólnego węgla organicznego (TOC). Ponadto określono wartość pH ścieków i ich zasadowość. Pobieranie próbek dopływających ścieków i pomiar parametrów fizykochemicznych przeprowadzano raz w tygodniu, na wiosnę. Zebrano łącznie 44 próbki ścieków. Określono korelacje między poszczególnymi parametrami i korelacje między stosunkami tych parametrów. Stwierdzono, że możliwe było oszacowanie, z wystarczającą dokładnością, wartości wybranych parametrów do oznaczania stężeń związków organicznych w ściekach komunalnych, znając wartości innych parametrów w tej grupie. Ponadto wykazano, że znając zależność między analizowanymi parametrami, można znaleźć równania regresji wielokrotnej dla danego typu ścieków, które pozwalają obliczyć pozostałe zależności przy dobrym dopasowaniu, o współczynniku determinacji R2 większym niż 0,6.

W pracy przedstawiono analizę pracy gminnej oczyszczalni ścieków typu „Lemna”, a badaniami objęto okres siedmiu lat (2009–2015). Badano sprawność usuwania takich wskaźników jak BZT5, ChZT oraz zawiesiny ogólnej. Pomimo bardzo wysokiej zmienności stężeń w ściekach dopływających, we wszystkich przypadkach stwierdzono wysoką skuteczność i niezawodność działania instalacji. Średnia efektywność usuwania zanieczyszczeń organicznych i zawiesiny ogólnej wyniosła 94,23% BZT5, 82,55% ChZT oraz 76% zawiesiny ogólnej i była dodatnio skorelowana z obciążeniem tymi parametrami ścieków surowych.
In this paper the analysis of „Lemna” municipal treatment plant performance is reported, the study covered a period of seven years (2009–2015). The efficiency of removal of such indicators as BOD5, COD and total suspended solids were examined. Despite the very high variability of concentrations in raw wastewater, high efficiency and reliability of the installation was found in all cases. The average removal efficiency of organic compounds and total solids was 94.23% for BOD5, 82.55% for COD and 76% for total suspended solids; moreover, it was positively correlated with the load on these parameters in inflow.

Opis:
Three emerging contaminants: amitriptyline hydrochloride (AH), methyl salicylate (MS) and 2-phenoxyethanol (PE) were treated by means of filtration processes for their elimination from ultrapure (UP) water in a first stage, and from three water matrices (surface water from a reservoir, and two effluents from two municipal wastewater treatment plants) in a second stage. For this purpose, ultrafiltration and nanofiltration membranes were used in a cross-flow laboratory equipment. The permeate fluxes at the steady state were determined, and the resistances to the permeate flux were established. It was found that the inherent resistance of the clean membranes provided a much larger resistance than the fouling resistance. The retention coefficients for each individual contaminant were evaluated, as well as the retention coefficients referred to three water quality parameters: absorbance at 254 nm, COD and TOC. These parameters provide the effectiveness of the filtration processes for the elimination of the organic matter present in the selected water matrices.

Celem badań było wykazanie zmienności składu ścieków mleczarskich, dopływających do oczyszczalni komunalnej w ciągu doby oraz w różnych porach roku. Analizom poddano ścieki z zakładu przetwórstwa mleka zlokalizowanego w Polsce północno-wschodniej. Określono charakterystykę produkcji zakładu przetwórstwa mleka, odprowadzającego ścieki mleczarskie do oczyszczalni komunalnej oraz ilości i ładunki ścieków mleczarskich i komunalnych. Analizy składu ścieków mleczarskich dokonywano w czerwcu oraz listopadzie 2014 roku. W każdym miesiącu wykonano 4 serie pomiarowe. Próbki ścieków mleczarskich podlegały analizom 8 razy w ciągu doby. Na podstawie wyników badań wyznaczono zależności pomiędzy wskaźnikami zanieczyszczeń organicznych oraz biogennych. Uzyskane wyniki porównano z podanymi w literaturze. Ścieki mleczarskie z Olecka charakteryzują się dużą zmiennością składu w ciągu doby, co może negatywnie oddziaływać na proces oczyszczania w oczyszczalni komunalnej. Stwierdzono różnice w ilości związków organicznych w ściekach mleczarskich w okresie letnim i jesiennym. Zdecydowanie wyższymi wartościami wskaźników BZT5 i ChZT charakteryzowały się ścieki w okresie wegetacyjnym.
Purpose of the study was to demonstrate the variability of dairy wastewater flowing into municipal WWTP per day and in different seasons. Research was carried out on effluent from Olecko milk processing plant located in north-eastern Poland. Characteristics of milk processing plant sewage discharge to the municipal treatment plant and the amount and loads of dairy and municipal wastewater was presented. The analysis of the qualitative composition of dairy wastewater was carried out in June and November 2014 year. Every month 4 series of measurements were performed and dairy effluent samples were analyzed 8 times a day. Based on the test results the relationship between indicators of organic pollutants and nutrients was determined. The results were compared with those presented in literature. Dairy wastewater from Olecko is characterized by varying composition during the day, which may negatively affect the purification process of municipal wastewater. There were differences in the amount of organic compounds in the dairy wastewater in summer and autumn. Significantly higher values of BOD5 and COD indicators were found in the sewage during the vegetation season.

Opis:
Municipal wastewater is characterized by diverse microbial content, largely dependent on their sources as well as many other factors like condition and health of their producer, but also environmental factors. The number and share of individual bacterial population in wastewater is changing during the process of their treatment in wastewater treatment plants. The microbial content of treated wastewater is significantly affected by the type of technology used for wastewater treatment. The paper presents the results of the species composition of bacteria present in the wastewater at various stages of treatment for the two different technologies. Samples of wastewater from hydroponic wastewater treatment plant and from the plant whose technology is based on biofilters were analysed. A key mechanism for wastewater treatment in both cases is biological treatment, using microbial activity that decomposes pollutants in the wastewater, which significantly contributes to changes in the species composition of bacteria comparing to microbiological composition of sewage flowing into the treatment plant. Analyses of microbial composition showed that in the objects consisting of preliminary tank and biofilter, composition of bacteria species is changing, but many species isolated from raw sewage is also found in treated wastewater. In the plant with hydroponic lagoon after wastewater treatment throughout the process system, bacteria present in raw sewage or in wastewater after biological treatment were not identified in the outlet.

Opis:
In recent years, the municipal WWTP operated by PEWIK Gdynia receives increasing quantity of industrial wastewater with COD/BOD ratio above 2. In most cases, it is probably due to the required reduction of certain pollutants before delivery of industrial wastewater to the sewage system. Implemented pre-treatment of industrial wastewater by on-site plants usually remove the nutrients and easily biodegradable organic matter, while other organic fractions are directed to the municipal WWTP. In this study the influence of industrial wastewater on the efficiency of technological processes was analyzed on the basis of WWTP in Gdynia-Debogorze. For this reason, the COD fractions (readily (soluble) and slowly (particulate) biodegradable fraction, and non-biodegradable soluble (inert) and particulate fraction) were analyzed in raw wastewater. Obtained results were discussed in terms of the efficiency of treatment processes as well as the energy consumption and the operating costs of the plant.

Opis:
The feasibility of effluent treatment in separate processes and in integrated systems has been compared. In the sorption process, carbon nanotubes were used in a pressure installation, enabling execution of the process of sorption with nanofiltration in a cross-flow system. Evaluation of treatment effects based on the measurement of typical pollution parameters (COD, TOC, phenolic index, forms of nitrogen and phosphorus) and concentration of bisphenol A. The results show poor feasibility of sorption as a process for advanced treatment of municipal effluent. Effluent polishing in integrated sorption-nanofiltration systems, however, guaranteed high removal rates of organic and inorganic pollutants.

Opis:
The effectiveness of co-treatment of leachates from an old site of municipal landfill with a dairy industry wastewater in a membrane bioreactor has been investigated. The subjects of the study were leachates collected at the municipal landfill in Tychy and dairy wastewaters from Dairy Plant in Bieruń. The determination of the most effective technological parameters of the process, i.e. activated sludge load and its concentration and types of COD fractions in the reactor influent was made. It was shown that the activated sludge load at the level of 0.06 g COD/(gDM·d) was the highest permissible one among all the investigated loads and the process run effectively within the whole investigated range of concentrations of activated sludge in a bioreactor. It was found that in the treated wastewater, the fraction of easily degradable organic compounds was the dominant one.
