Abstract
The experiences with design and operation of constructed wetlands in the Pommerania region during last 30 years followed by carried out investigations of treatment processes lead to the following conclusions:First applications of constructed wetlands for biological sewage treatment were made in 1984-92. The later implementations of multi-stage constructed wetlands in the individual household and local scale enable wastewater treatment according to the rule of sustainable development, with special impact on natural treatment processes and elimination of by-products. The investigations carried out in the years 2008-10 indicated that constructed wetlands can provide effective removal of toxic pollutants from reject waters from sewage sludge centrifugation and from municipal landfill leachate. The new application of constructed wetlands in Poland is treatment of stormwater runoff and protection of streams in the urbanized area against the inflow of huge loads of pollutants during rain events. The reed beds provide dewatering and stabilization of sewage sludge with the efficiency similar to mechanical devices used in highly effective wastewater treatment plants
