人工湿地是20世纪七八十年代发展起来的一种污水生态处理技术,能高效去除有机污染物,氮、磷等营养物,近年来得到了广泛的应用。对磷的去除不同于常规化学除磷或生化处理工艺,而是集物理化学法和生物法于一体,即通过基质、水生植物及微生物的协同作用完成。基质容易达到饱和是人工湿地除磷面临的主要问题,进水水质、水力条件、温度变化等条件也不同程度影响人工湿地的除磷效果。针对以上问题,提出了相应对策,以实现人工湿地除磷系统的稳定运行。
人工濕地是20世紀七八十年代髮展起來的一種汙水生態處理技術,能高效去除有機汙染物,氮、燐等營養物,近年來得到瞭廣汎的應用。對燐的去除不同于常規化學除燐或生化處理工藝,而是集物理化學法和生物法于一體,即通過基質、水生植物及微生物的協同作用完成。基質容易達到飽和是人工濕地除燐麵臨的主要問題,進水水質、水力條件、溫度變化等條件也不同程度影響人工濕地的除燐效果。針對以上問題,提齣瞭相應對策,以實現人工濕地除燐繫統的穩定運行。

Constructed wetland, which has a high removing rate of organic pollutant, nitrogen, phosphorus and other nutrients is an ecological wastewater treatment technology developed in seventies and eighties of the 20th century. It has been widely applied in recent years. The removal of phosphorus is different from conventional chemical phosphorus removal or biochemical process, but combining physico - chemical and biological treatments or the interaction of the substrate, plants and microorganisms. But the main problem is the substrate easy to saturate. The water quality, hydraulic condition and the change of temperature also influence the removal rate of phosphorus. This article proposed some countermeasures to these problems in order to keep the tranquilization function of the wetland.
