潜流人工湿地系统对污染物的去除与转化机理

Removal and Transformation Mechanisms of Pollutant in Subsurface Flow Constructed Wetland

潜流人工湿地通过硝化、反硝化、累积、降解、络合、吸附、沉淀、拦截等作用实现对去污水中TSS、有机物、N、P、金属以及病原菌的去除。这些作用发生在水体中、植物表面、湿地表面和底部的垃圾积累物中,或发生在根区系统而使污染物得以去除。

Subsurface flow constructed wetland system remove TSS,N,P,Pathogen,organic compound and metal by nitrify,denitrify,accumulation,degradation,complexing,adsorption,sedimentation,interception and so on.These reactions may occur in the water body on the surfaces of plants.within the litter accumulation at the wetland surface and on the bottom or within the root zone of the system.
