The Algal Inhibition of Aquatic Plants in Landscape Pond Supplied by Reclaimed Water
The landscape pond was supplied by reclaimed water from the secondary sewage purification water in the second sewage purification factory of Taiyuan. A comparison was made between phragmites, typha and iris pseudacorus to study their effects on water purification and algal inhibtion. in the reclaimed water condintion. The variations of TP, TN and Chlorophyll-a were analyzed in the experiment. The results showed that phragmites, typha and iris pseudacorus could control the water quality and the algal growth in reclaimed water. By planting aquatic plants, the TP content could reduce from 0.83 mg/L to 0.1 mg/L, and reached the surface water bodies V standards; the TN content was lower than 15 mg/L, and met the I-class A criteria; phragmites had a better removal capacity of TP, while Typha had a better removal capacity of TN. The algal inhibiting ability were: phragmites > typha > iris pseudacorus. Phragmites could control the algal growth better than typha and iris pseudacorus, and its algal inhibition rate reac hed up to 90％.
