生态塘技术特点及在农村污水处理中的应用

Characteristics and Application of Treating Rural Domestic Sewage with Ecological Pond System

生态塘污水处理系统是一种结构简单、投资少、维护方便、运行成本低的新生态处理系统。采用人工湿地和生态塘工艺处理农村生活污水,监测结果表明该工艺去除有机物、氮、磷能力强,出水各污染指标均能达排放要求,CODCr去除率达89.74%,氨氮的去除率达75.18%,TP的去除率达82.11%。采用该工艺处理农村生活污水可以实现污水资源化利用,具有良好的生态效益。

The ecological pond sewage treatment system is one kind of simple structure, low investment, easy maintenance, low operation cost new ecological treatment system. The artificial wetland and ecological pond craft were adopted to process rural sewage, the monitoring results indicated that the process show strong ability in removing organic matter, nitrogen, phosphorus, and water pollution index can reach emission requirements, the CODcr elimination rate reaches 89.74%, the ammonia nitrogen elimination rate reaches 75.18%, and the total phosphorus elimination rate reaches 82.11%. Adopting this craft to process rural sewage can realize sewage recycling and has a good ecology benefit.
