人工湿地法处理农业非点源污染的研究

Study of constructed wetland in agricultural non-point source pollution control

简述了人工湿地法去除氮、磷、有机物的主要机理、人工湿地内植物的作用及其它一些问题,从而说明了人工湿地是一种造价低、运行简单及管理方便的农业非点源污染控制系统。并详细论述了人工湿地环境效应和经济效应,为人工湿地处理农业非点源污染技术的应用提供了参考。

This paper describes effect of agricultural non-point source which is harmful to water environ- ment,the types of constructed wetland,the mechanism of nitrogen,phosphorous and organic compound remov- al,the choice of plants and their function in wetland. At the same time,environmental and economic effects are discussed in detail,which supplies useful reference for the applied research of the purification technology of constructed wetlands.
