Since 1991, Poland has been taking steps to organize the country's wastewater management in order to meet the requirements of Council Directive 91/271/EEC. The current goals to achieve the said requirements are set in the VI update of the National Urban Wastewater Treatment Program (KPOŚK) and has to be achieved to 2027. The article presents the status of water and wastewater management in the districts of Lubuskie Voivodeship, Poland in 2021, in relation to year 2017. The degree of water supply and sewerage system, as well as wastewater systems management in individual agglomerations of Lubuskie Voivodeship are defined.

Agricultural policy in the European Union at Community level, as well as in the member states, increasingly emphasises the issue of sustainable agriculture. The pursuit of climate neutrality requires a reduction in emissions from agricultural sources. Above all, it is necessary to fully exploit the potential of agricultural and forestry areas to increase carbon sequestration in biomass and soil, optimise systems for the storage, transport and use of livestock manure, and significantly improve energy efficiency and increase the share of renewable energy in plant and livestock production. Rural areas, and in particular agriculture, are also seen as one of the main and important sources of pollution and eutrophication of water. Determining the correct way to assess the degree of sustainability of farms requires objective and feasible to determine measures and indicators of socio economic-environmental sustainability and a lot of analysis, methodological and practical research. To date, no uniform set of sustainability indicators has been developed and their selection depends on data availability.

Content available The Influence of the Poles’ Lifestyle on the Quantity and Quality of Municipal Wastewater

The article presents lifestyle as an important factor determining the quantity and quality of municipal wastewater. The characteristic of wastewater in Poland has changed significantly in recent years. The qualitative characteristics of municipal wastewater indicate an increase of organic compounds and in the scope of micro-contaminants identified in them, e.g. nanoparticles, microplastics, pharmaceutical and personal care products or heavy metals. Therefore, the knowledge of parameters such as: BOD5, COD, total N, total P and suspension solids is no longer sufficient for the design and operation of wastewater treatment systems. Comprehensive research in this area is necessary to select those indicators that better describe the characteristics of wastewater.

Most of the plastic produced, being one-use plastic packaging, is finally disposed of into the environment. Several agents such as solar radiation, mechanical forces, and microbial action may enable the degradation of these plastics. The purpose of this article is to present a method for studying the properties of a surface of a microplastic particle affected by erosion at the microscale level, which occurred with the help of destructive forces associated with the impact of the sea. The results of analysis of the morphology of the tested sample of microplastic (consisting of poly(propylene)) allowed observing how it was degraded. Examining the surface of a microplastic, one can analyze a number of factors as well as determine the possible path the material has traveled until it was collected as a sample. By determining the scale of the patterns, it is possible to estimate how long the sample and other microplastics present in marine environments have been there. The use of an Atomic Force Microscope not only allows the surface of the sample to be imaged in a non-destructive manner but also enables the degree of degradation to be calculated mathematically, provided a baseline is established from which erosion can be assumed to have originated.

Content available Significance of Wastewater Treatment to Nitrous Oxide Emission

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.

W ostatnich latach efektywność energetyczna w branży wodno-ściekowej zyskuje coraz bardziej na znaczeniu, ponieważ oczyszczalnie ścieków odpowiedzialne są za blisko 35% zużycia energii ze wszystkich obiektów komunalnych [1]. Odprowadzanie ścieków oczyszczonych do odbiorników zgodnie z obowiązującymi wymaganiami prawnymi wymusza stosowanie efektywnych technologii usuwania zanieczyszczeń i procesów przeróbki osadów ściekowych.
