摘　　要：人工湿地作为一种新型的污水处理实用新技术,正受到人们越来越多的关注。本文详尽地介绍了人工湿地的除污机理,分别就该工艺中氧的变化特性,对有机物、N、P的去除机理及湿地中微生物的特征作了阐述,简要分析了影响人工湿地净化效果的主要因素,从而为该技术的推广提供理论参考。As a new and practical technology of wastewater treatment, constructed wetland has become popular more and more. This paper introduced the purification mechanism of constructed wetland in detail, described the variable characteristics of oxygen in this technique and the removal mechanism of organism, nitrogen and phosphorus and characteristics of microorganism in wetland separately, and discussed briefly several primary factors that influence the purifying effect of constructed wetland. This work could provide the theoretical references for the popularization of this technology.
