人工湿地基质研究进展

Research Development of Substrates in Constructed Wetland

基质是人工湿地的重要组成部分,关系着湿地的净化能力和使用寿命.本文综述近年来人工湿地基质的研究成果,包括基质在人工湿地污水处理中的重要作用,不同基质的去污效果,基质脱氮除磷的机理与影响因素,形成淤堵的机理及防堵措施,论述基质的选择与配置原则,提出今后研究的重点.

Substrate,the essential component of constructed wetland,is related much to the capacity of purification and longevity of wetland. This paper reviewed the current research progress of substrate in constructed wetland by means of such issues as the important role in the process of wastewater treatment that substrate played,the capacity of purification by different substrates,the mechanism and factors that substrate removed nitrogen and phosphorus,and the mechanism and treatment of clogging.Based on these researches, this paper discussed the fundamental of substrate＇ s selection and configuration. By the way, some promising directions of research in future were put forward.
