| 摘 要： | 为了使太湖地区农村污水处理达到占地面积小、除磷脱氮效率高、管理简单、运行和建设费用低的目标，采用厌氧／跌水充氧接触氧化／人工湿地组合工艺进行了工程规模的试验研究。结果表明，在厌氧池水力停留时间为2d、5级跌水充氧接触氧化池总水力停留时间为2h、并采用50cm／d的高水力负荷人工湿地的条件下，该组合工艺对COD和TN的平均去除率分别为81％和83％，对TP的平均去除率在进水TP〉1．5mg／L时达82％，在进水TP〈1．5mg／L时为72％。

| Abstract: | In order to meet the technical requirements of smaller occupancy area,higher efficiency of nitrogen and phosphorus removal,easier maintenance and lower operation and construction cost in the treatment of rural sewage in the Taihu Lake valley,a full-scale experiment on use of the combined process of anaerobic/waterfall aeration contact oxidation/constructed wetland was carried out.The operating parameters are set as follows: HRT of 2 d in the anaerobic tank,HRT of 2 h in the five-step waterfall aeration contact oxidation and HLR of 50 cm/d in the constructed wetland.Under these operation conditions,the average removal efficiencies of COD and TN are 81% and 83% respectively,and the average removal efficiency of TP reaches 82% and 72% when the influent TP is higher than 1.5 mg/L and lower than 1.5 mg/L. |
