Abstract
The purpose of the study was to evaluate the functioning of a household hybrid constructed wetland wastewater treatment plant located in Poland under moderate climate conditions. The research also established how the air temperature and the temperature of the constructed wetland bed impact the efficiency of removing pollutants from wastewater. The study was carried out during 12 months and the analysis focused on the physical and chemical composition of wastewater following three treatment stages, including mechanical processing in an initial settling tank and biological processing in constructed wetland beds with both vertical and horizontal flow configurations. The wastewater was assessed for several indicators including BOD5, COD, total suspended solids, total nitrogen, and total phosphorus. Furthermore, the study also examined the air temperature alongside the temperature within the constructed wetland bed. The discussed facility was characterized by high efficiency and reliability of the tested pollutants removal across the seasons, regardless of any changes in thermal conditions. The levels of the examined pollution indicators in the treated wastewater remained within the permissible limits outlined in the current legal regulations in Poland. Thus, it can be concluded that the studied facility got wastewater to a state in which it posed no threat to the surrounding environment. The research showed that hybrid constructed wetland systems are good solutions for wastewater treatment in unsewered areas and can successfully help to protect water resources.
