The study on the species selection of constructed wetland plants and the purification effects of the constructed wetland plants is the key to ecological wastewater treatment technology. The purification effects of different residence time of wastewater, different constructed wetland plants and their synergistic effect are studied in TP disposal in living wastewater. The results show that the best plant combination in purifying TP is that of Arundo donax, Typha orientalis and Canna generalis, followed by that of Phragmites communis, Arundo donax and Canna generalis. The best plant species in purifying TP is Canna generalis, followed by Arundo donax.

Polluted Waters

Experience from advanced municipal wastewater treatment plants and recovery of polluted waters are described for the last ten years in Sweden. Except in municipalities with large recipients, the urban population is served by treatment plants with combined biological and chemical treatment. Most of these plants are post-precipitation plants. Several modified operational modes have been developed in order to improve the removal efficiencies of pollutants and to reduce the costs. Results are presented on the recovery of specially investigated lakes with a lowered supply of total phosphorus and organic matter.
