Study on the Purification Effects of Constructed Wetland Plants in TP Disposal in Living Wastewater

Abstract:

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.
