摘要
介绍了人工湿地生态系统去除污水中氮磷的机理,并从工艺优化、湿地植物、基质和微生物四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;通过优化湿地系统设计、湿地植物的筛选、基质的选择和复合、微生物种群的调控等可以有效提高人工湿地的氮磷去除率,提出了当前人工湿地研究中存在的问题和研究方向。
Constructed wetland and its removal mechanisms of nitrogen and phosphorus in wastewater treatment were introduced. Latest research status of removal efficiency improvement of nitrogen and phosphorus were systematically expatiated on process optimization, wetland plants, substrates and microorganisms. Some proposals about the ways to improve the removal efficiency of nitrogen and phosphorus were given, such as optimizing the design of constructed wetland system, screening of wetland plants species, combination of substrate, and microorganism population adjustment in the bed of constructed wetland. Based on which the current problem and research orientation of constructed wetland were discussed.
