MECHANISMS OF WATER POLLUTION TREATMENT IN MANMADE WETLAND

Received Date: 01 December 2010

摘要: 湿地特殊的生态环境和水化学循环能力对污水有着很好的净化作用,基于此,越来越多的国家和地区开始构建人工湿地,以处理水污染。从自由表面流、垂直潜流、自由漂浮的大型植物3种不同类型的人工湿地角度介绍了其对水中污染物的去除机理,特别阐述了人工湿地系统对氮、磷污染物的去除过程。

Abstract: Due to its water geochemical recycling capacity, wetland is regarded as a specific ecological environment for sewage purification. More and more countries and regions have constructed manmade wetlands to satisfy the public with water pollution treatment. This article introduces the mechanisms to remove contaminants from free surface flow, vertical subsurface flow, and free floating macrophyte, with emphasis on the removal of nitrogen and phosphorus by manmade wetland systems.
