浅谈生态型农田排水沟的设计与试验研究

Discussion on design and experimental research of ecological farmland drainage ditch

农田面源污染治理属于综合性治理,生态排水沟是其中一项重要的工程措施。本文介绍了一种新型的农田生态排水沟型式,并详细阐述了设计思路和设计方案。研究人员在上海青浦某基地建造了长度110m的新型生态排水沟进行现场试验。本文根据试验成果,分析了该新型生态排水沟对氨氮、总磷的削减效果,并同时考察了排水沟的生态效果。本次研究成果可为农田面源污染防控研究提供一定参考。

Farmland non-point source pollution control belongs to comprehensive management,and ecological drainage ditch is one of the important engineering measures.This paper introduces a new type of farmland ecological drainage ditch,and expounds the design ideas and schemes in detail.Researchers built a 110m long new ecological drainage ditch at a base in Shanghai Qingpu for field tests.Based on the experimental results,this paper analyzed the reduction effect of the new ecological drainage ditch on ammonia nitrogen and total phosphorus,and also investigated the ecological effect of the drainage ditch.The research results can provide some references for the prevention and control of farmland non-point source pollution.
