摘要
介绍了人工湿地及其去除污水中氮磷的机理,并从湿地植物、基质和微生物三个方面系统地阐述了目前人工湿地系统提高氮磷去除率的研究进展情况;提出了可以通过改良湿地系统设计提高氮磷净化效果、利用培养优化菌种与调节环境条件促进湿地系统氮磷的转化及通过在基质中添加合适的附料、提高人工湿地系统植物多样性从而增加氮磷的吸附吸收的建议,为人工湿地污水净化技术的应用研究提供了有益的参考。
In this paper, constructed wetland and its removal mechanisms of nitrogen and phosphorus in wastewater treatment were introduced. Recent research status of removal efficiency improvement of nitrogen and phosphorus were systematically expatiated on via wetland plants, substrates and microorganisms. Some proposals about the ways to improve the removal efficiency of nitrogen and phosphorus were given, such as meliorating the design of constructed wetland system, practicing bioaugmentation by the dominant species and optimal condition, appending subordinates in the substrate, and enhancing biodiversity in the bed of constructed wetland.
