人工湿地在农业面源污染控制中的应用研究

Study on the Application of Artificial Wet land in Agriculture Non Point Source Pollution

由漂浮植物池、沉水植物池、挺水植物池以及草滤带组成的人工湿地，对氮、磷、泥沙以及有机物有较好的吸收、吸附以及物理沉降作用，可以控制农田径流污染，具有工艺简洁，运行管理方便，生态环境效益显著，投资少等优点，是控制农业面源污染的实用工程技术。

The artificial wet land composed of float vegetation pond, submerged vegetation pond and emergent vegetation pond and grass filtering belt can absorb, adsorb and physically settle nitrogen, phosphorous and organisms efficiently. It can control agriculture runoff pollution with simple technique, convenient operation and management, and remarkable eco environmental efficiency.So it is a practical engineerng technique for the control of agriculture non point source pollution.
