摘要
综述了人工湿地处理生活污水的净化机理及影响因素。人工湿地作为一种有效的生活污水生态处理系统,其作用机理包括吸附、沉淀、过滤、氧化还原、微生物分解、转化、植物吸收及其他各类生物作用。人工湿地结构、系统运行参数和环境因子都对人工湿地系统污污染物的净化效果产生重要影响。人工湿地对于生活污水中氮磷以及金属离子的净化机理将是今后研究重点。
A review of purification mechanization and influencing factors on the domestic sewage treatment in the constructed wetland were summarized. As a effective ecological treatment system for the domestic treatment, the purification mechanization in constructed wetland include adsorption; deposition; filter; redox; microbial decomposition; transform; plant uptake and other biological agent. The purification capacity on the contaminant in the constructed wctland is influenced by the structure of constructed wetland, operational parameters and environmental factors. The hereafter research will focus on the purification mechanization on the nitrogen, phosphorus and metallic ions in domestic sewage by constructed wetland system.
