    Opis:
    Suspended solids in water and wastewater usually carry quite a large load of pollutants (organic substances, nutrients, heavy metals, etc.) adsorbed on the particles surface. Particles of different sizes carry different types and quantities of pollutants. Therefore, particle size distribution is of importance in waster and wastewater treatment. In the article the influence of different treatment technologies on particle size distribution in the effluent was assessed. The analyses covered the effluents from two municipal wastewater treatment plants, drainage water, clean stormwater, oil-contaminated water and industrial sewage treated at the oil refinery and the water of a stream contaminated with stormwater run-off, treated in a constructed wetland. The equivalent diameters of particles were similar for all analyzed types of wastewater, however the share of different particle sizes in the total volume was different.

    Opis:
    During the last 30 years the increase of interest in low-cost decentralized and small wastewater treatment plants (WWTP) is observed in Europe. For this purpose, sand filters, stabilization ponds, mini reactors with activated sludge, trickling filters and treatment wetlands are used. Among the listed facilities, treatment wetlands (TWs) offer effective and reliable treatment efficiency, being at the same time low-cost and simple in operation. This is a sustainable treatment technology which does not generate secondary sewage sludge. In the paper, design concept and performance of nine TWs constructed in 2009 for single-family households in Kashubian Lake District is discussed. The treatment efficiency of three different TW configurations is compared. The findings of the study provide a basis for future design and implementation of TWs in agricultural areas.

    Opis:
    The Baltic Sea is highly susceptible to eutrophication. Among the nine countries located in the Baltic Sea catchment area Poland discharges the biggest load of nitrogen and phosphorus. Although in recent years this load has been significantly reduced, however it is still too high. No sustainable municipal management results in the decreasing water quality of the Baltic Sea contributing to the sea eutrophication. The implementation of the National Programme for Development of Sewage caused a number of activities related to the construction and modernization of existing wastewater treatment plants. Although the number of wastewater treatment plants has been constantly increasing, still a number of households do not have the possibility to connect to the municipal wastewater treatment plant, mainly for economic reasons. Although in Poland there is 3157 municipal wastewater treatment plants (the most in Central and Eastern Europe), only 64% of the population is connected to them. It is estimated that 7.64 million people do not have the possibility of connection to municipal wastewater treatment plants. One of the solutions to wastewater management, especially in non-urbanized areas, are on-site wastewater treatment plants, for example treatment wetland systems. These technologies provide a sustainable solution of sewage and sludge management, since they can be used not only for treatment of wastewater, but also for dewatering and stabilization of produced sewage sludge. The article presents the results of research on local constructed wetlands for biological wastewater treatment (from 15 to 750 inhabitants) located in Darżlubie, Wieszyno, Wiklino, Sarbsk and Schodno as well as individual treatment wetlands representing 9 on-site wastewater treatment plants built in three different configurations in the municipality of Stężyca. There are also results of research from sludge treatment reed beds used for dewatering and stabilization of sewage sludge from municipal wastewater treatment plants located in Denmark (Helsinge, Rudkobing, Nakskov, Vallo) and in Poland (Gniewino). Based on studies related to the latest examples of wastewater and sewage sludge management using treatment wetlands it has been shown that this method is a good example of ecological engineering. Local treatment wetland systems can be used as the second stage of wastewater treatment up to 3500 residents. With proper operation of primary tanks, these systems are characterized by high treatment efficiency. Treatment wetland systems can work as on-site wastewater treatment plants. The highest efficiency of pollutant removal was observed in the hybrid systems. Another facilities, constructed as reed beds or basins, are applied to effective dewatering and stabilization of sewage sludge. These facilities offer a sustainable solution of sludge management in local conditions.
