生态浮岛处理微污染水体综述

REVIEW OF MICRO-POLLUTED WATER TREATMENT BY ECOLOGICAL FLOATING ISLAND

在自然水体经历了从重度污染到微污染转变的过程中,生态浮岛技术具有投入少、操作性强、无二次污染等特点,在湖泊、池塘、景观河道等微污染水体治理中被广泛应用。分别从净水系统的构建、污染物去除机制、净水效果与成本分析、微生物群落变化及其功能分析方面来阐述生态浮岛的发展现状。提出今后有关浮岛技术研究中应阐明浮岛的建造及运行成本、发掘微生物信息,解释浮岛微生物降解机制,为进一步优化浮岛运行效果、为水环境治理和水生态维护提供依据。

With the improvement course of natural water from heavy pollution to micro-pollution,the ecological floating island with characters of low cost,simplify operation,no secondary pollution has been extensively used in the treatment of micropolluted water,such as lakes,ponds,landscape rivers.This paper elaborates the development status of the ecological floating island from the aspects of construction of water purification system,removal mechanism of pollutants,purification effect and cost analysis,changes in microbial community and functional analysis respectively;and suggests that in the future study on ecological floating island,the construction and operation costs shall be elaborated,microbial information be explored and the microbial degradation mechanism be explained,thus to provide a basis for further optimization of the operation effect of ecological floating island,water environment management and ecological maintenance.
