Use of New Type Constructed Wetland for Treatment of Low Strength Rural Sewage

Open publisher page 4 citations

Abstract

Experiment was made on the use of artificial wetland to treat low strength rural sewage in the Lake Dianchi area, Yunnan. The experimental results showed that the removal rate of COD, TN, ammonia nitrogen and TP is 59.6%～70.6%, 50.4%～60.6%, 70.8%～83.0%, and 55.0%～66.0% respectively under high hydraulic loading rate (30 cm/d). Because the reed has higher capability in oxygen transfer and the indian rice is good at absorbing nitrogen and phosphorus, pollutants removal efficiency can be greatly improved when the reed and Indian rice grow together in wetland.
