摘　　要：采用人工复合生态床处理滇池地区低浓度农村污水的试验结果表明 ,在 30cm/d的高水力负荷条件下 ,4个不同的单元床体对COD、TN、氨氮和TP的去除率分别为 5 9.6 %～70 .6 %、5 0 .4 %～ 6 0 .6 %、70 .8%～ 83.0 %和 5 5 .0 %～ 6 6 .0 %。因芦苇具有较强的输氧能力 ,而茭白对氮、磷的吸收能力强 ,因此芦苇和茭白混种是一种较好的植物栽种方式。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.
