    Opis:
    The aim of this study was to assess the impact of the reuse of purified wastewater from the wastewater treatment plant in the city of Settat on the physicochemical quality of agricultural soils compared to the agricultural soils irrigated by rainwater in the region of Chaouia in Morocco. The results obtained showed that despite the great fertilizing value of the purified wastewater, a slight increase in salinity was noted; they also reveal a significant difference in pH. The accumulation of sodium, total limestone and active limestone in the soil increased significantly in the soils irrigated by treated wastewater; in contrast, calcium increased significantly in the soils irrigated by rainwater.No significant differences were recorded for humidity, electrical conductivity, ammonium, nitrates, phosphorus, potassium, organic matter, total nitrogen or cation exchange capacity.

    Opis:
    The possibility of obtaining sorbents with a good sorption capacity from miscanthus has been investigated. The chars and the activation products were obtained from the miscanthus in a rotary furnace. The activation process of miscanthus was carried out by water vapour at 700 - 800°C and at the activation time of 30 - 90 min. We found that the optimum conditions for the activation process were: the activation temperature of 750°C (activation time of 60 and 90 min) and 800°C (activation time of 45 or 60 min). For these conditions the sorbents with the best sorption capacity for p-chlorophenol, toluene, methylene blue and Congo red were obtained.

    Opis:
    Polluted water poses significant health risks when it is part of the water sources used for irrigation, leading to the contamination of soil and plants by various pollutants. This work aims, firstly, to assess the degree of pollution of Wadi El Gourzi water (Batna, Algeria), and then to verify the consequences on their use for the irrigation of market garden plants for everyday consumption (lettuce, cilantro, parsley and spinach), both in the aerial part (stems and leaves) and in the soil where they are grown. This study focuses on trace metals (Cr, Pb, Zn and Cd). Soil pollution was assessed by calculating the soil pollution index (PI), while the uptake of these elements by plants was monitored by the transfer factor (TF). The analyses of the Wadi El Gourzi water with the flame atomic absorption spectrophotometer (FAAS) show a maximum abnormal concentration of Cr (17.37 mg∙dm-3), Pb (0.71 mg∙dm-3) and Cd (0.45 mg∙dm-3). For the analysis of the soils irrigated by these waters, the results of the PI show that the soils used for the cultivation of parsley and lettuce are polluted by several metals (PI > 1). The concentrations of trace metals elements (TMEs) in the sampled plants show a significant accumulation of Zn, Cd, Pb and Cr by the vegetables (coriander, parsley, spinach and lettuce). These concentrations are above the permitted standards.

    Opis:
    W artykule opisano technologie pozyskiwania biogazu z trzech źródeł: składowisk odpadów komunalnych, oczyszczalni ścieków i biogazowi rolniczych. Scharakteryzowano parametry wytwarzanego biogazu oraz przedstawiono techniczne możliwości wykorzystania energii zawartej w biogazie poprzez: spalanie w urządzeniach cieplnych i w kotłach gazowych, wytwarzanie energii elektrycznej w silnikach gazowych z generatorem prądu, produkcję energii w skojarzeniu (kogeneracja lub trigeneracja) oraz wytwarzanie biometanu (SNG), który można następnie: zatłoczyć do sieci dystrybucyjnej gazu ziemnego, wykorzystać jako paliwo transportowe lub w procesach technologicznych, np. do produkcji metanolu. W oparciu o dane literaturowe oraz wyniki badań własnych scharakteryzowano rynek energetyki odnawialnej w Polsce.
    Presented are technologies for landfill gas production from municipal waste dumps, sewage treatment plants and agriculture biogas plants. Provided are parameters of biogases and possibilities of using them for power generation purposes in heat plants and gas boilers. The biogas may be also used in gas engines equipped with power generators, heat and power generation installations and for production of biomethane./SNG/. SNG is usually pumped into gas distribution network or used in methanol production process. Discussed are problems related to polish sector of renewable energy basing on our own knowledge and other information.

    Opis:
    The sewage sludge recycling as an agricultural land resource has received a great deal of attention worldwide. This practice has highly increased because of ever-increasing municipal wastewater production and the awareness of its fertilizing potential as amendment resources. However, there is a concern about land spreading linked mainly to health associated risks due to the presence of diverse pollutants. Thus, sewage spreading management is a key factor the guarantees benefits and avoids risks. The present work aimed to investigate the benefits and risks of sewage sludge (SS) application on agricultural land. To this end, physicochemical main parameters and bacteriological indicators, fecal coliform (FC) and fecal streptococcus (FS), of the sewage sludge generated form WWTP of Skhirat, Morocco, were performed during the period 2018–2019. The obtained results of physicochemical parameters reveal high concentration of organic matter in SS, which reach 96.3 mg/l, and in nutrients. Indeed, total Kjeldahl nitrogen TKN reaches a maximum of 3791 mg/l, potassium K+ reaches 58.71 mg/l. In addition, the average content of FC and FS are around 5.40 CFU/ml and 5.85 CFU/ml, respectively, whereas total phosphorus reaches 508.25 mg/l. In addition, concentrations of micronutrients such as Cl-, SO42-, Ca2+, Mg2+, and Na+ were high, which is interesting and could benefit for both soils and plant. Furthermore, this sewage sludge contains high concentration of heavy metals, mainly zinc and copper which could limit reuse in land spreading. The obtained results were compared to the applied standards and directives established within the framework of the agricultural spreading.

    Opis:
    The aim of this study was to evaluate selected elements of the management of domestic and production sewage and an estimate of amount of macroelements NPK in domestic sewage, used on fields in selected farms of Wielkopolska voivodeship. The main sources of data were special designed questionnaires taken in selected farms. The data were combined with information obtained in The Agricultural Advisory Center in Poznań and communities and included the period 2004−2010. The study area was covered by eight communities situated in the central part of Wielkopolska region - Borek Wielkopolski, Dolsk, Gostyń, Jarocin, Koźmin Wielkopolski, Krzywiń, Piaski and Śrem. 72 conventional farms, diversified in terms of their size, specialization, crop and animal production were also chosen. The examined farms were subjected to detailed characterization in terms of their sphere of production. Domestic wastewater management, using the method of preparation of silage, and the degree of risk to the environment due to the risk of leakage into the soil silage juice were analyzed. Content of nitrogen, phosphorus and potassium in samples taken from 16 different farms was analyzed. Quantity of nutrients in domestic wastewater and which could be possibly applied to the field were calculated. The study shows that 83% of the analyzed farms had access to water supply. Due to the lack of proper infrastructure and the possibility of alternative wastewater management and disposal of domestic waste, farmers often applied sewage directly into the fields. 49% of produced sewage is poured directly into the fields. None of the 16 domestic sewage samples meets permitted standards for nitrogen concentration. Only one because of phosphorus and 11 due to potassium the predetermined limits of nutrient concentration in domestic sewage introduce into the soil or water does not exceed. On average with wastewater farmers brought in the agricultural land 12 kg of N, 3 kg of P2O5 and 16 kg of K2O per 1 ha. The problem there is also the method of preparation silage piles. As many as 56% of farmers prepares piles directly on the ground, without isolation, with the risk of penetration of pollutants into groundwater and surface water.
