摘要
磷是导致水体富营养化的主要因素之一,人工湿地能够经济有效地去除水体中的磷。本文论述了人工湿地除磷的机理,对人工湿地中植物、微生物和基质去除污水中磷的物理、化学及生物作用机制进行了综述。讨论了温度、溶解氧、水力停留时间和水力负荷等因素对人工湿地净化磷的影响。探讨了无基质人工湿地代替传统人工湿地去除水体中污染物的发展和应用情况。
Phosphorus is one of the main causes of eutrophication of water bodies. Constructed wetland can remove phosphorus effectively and economically. This paper discusses the mechanism of phosphorus removal in constructed wetland, and reviews the physical/chemical/ biological reactions for phosphorus removal by wetland plants, microorganisms and media in the constructed wetland. The effects of temperature, dissolved oxygen, hydraulic retention time and hydraulic load on the phosphorus purification in constructed wetland are discussed. The development and application of non-media constructed wetland for pollutants removal in water are also discussed.
