太湖流域某市农村生活污水处理工艺的比较研究

农村生活污水处理是中国“十二五”期间农村环境保护工作的重要内容。对太湖流域某市近年来所采用的5种农村生活污水处理工艺的原理进行了分析，对其运行状况进行了长达一年的跟踪监测，就其投资、建设与运行成本和处理效果进行了比较和总结。其中工艺三处理效果最好，但是投资和运行维护费用也相对最高，工艺四虽然具有投资和运行维护方面的优势，但是处理效果较差，工艺一和工艺二具有投资相对较低，运行维护相对简单，处理效果能够满足要求，是比较适合的农村生活污水处理选择。

Comparative Study on Rural Sewage Treatment Process in a City around Taihu Lake

Rural sewage treatment is an important part of rural environmental protection in China＇s 12th Five - Year plan peri od. The 5 rural sewage treatment processes adopted by cities around The Taihu basin were analyzed based on the operating condi tions of one year monitoring. The investment, construction and operation costs and the treatment effect were compared and summa rized. The treatment effect of the third process is better, but the investment and operation cost is more expensive. The investment and operation cost of the fourth process have advantages, but its treatment effect is poor. The first process and the second process are the optimal choices of the rural sewage treatment, because the investment and operation cost of them is lower and he treatment effect can meet the standards.
