基于小型湿地的农田排水处理系统设计与实现

Farmland Drainage Treatment System Based on Miniature Wetland

针对我国目前农业面源污染严重的现状,在前人研究的基础上提出基于小型湿地的农田排水处理模式。通过理论分析和实例研究表明,该系统可以有效地降低农田排水的氮磷浓度,改善农田排水水质,减少农业面源污染。

Aiming at the present situation of China＇ s serious non-point source pollution, this paper puts forward a farmland drainage treatment system model based on miniature wetland. Through theoretical analysis and case study, it shows that the system can reduce the concentration of nitrogen and phosphorus in farmland drainage effectively, and improve water quality of farmland drainage, and alleviate the agricultural nonpoint source pollution.
