摘要:

人工湿地作为一种投资少、能耗低的水处理系统,被广泛应用于各种水处理之中,与传统的处理工艺相比有较好的稳定性和生态效果。在人工湿地系统中,基质、水生植物和微生物对污染物的去除有着重要的影响。综述了人工湿地脱氮除磷的机理,讨论了基质、水生植物、微生物及进水条件对系统处理效果的影响,提出了当前人工湿地研究中存在的问题和提高人工湿地脱氮除磷能力的措施。

关键词: 脱氮除磷, 人工湿地, 污水处理

Abstract:

The constructed wetland as a low payment and lower power water treatment system has widely been used nvarious types of water treatment. Compared with traditional treatment processes it has better stability and ecological effects. In this system substrate aquatic plants and microbes have important influences on the removal of pollutants. The mechanisms of denitrification and dephosphorization by using constructed wetland are summarized. The effects of substrate aquatic plants microbes and influent water conditions on the treatment effectiveness by using this system are discussed. Current problems existing in the research of constructed wetland system and the countermeasures for improving the denitrification and dephosphorization capacities are brought forward.

Key words: denitrification and dephosphorization , constructed wetl, sewage treatment
