人工湿地微生物的研究进展

Study Progress on Microorganism in Constructed Wetlands

人工湿地是20世纪70年代末得到迅速发展的一种污水处理技术工程,具有投资低、运行费用低、维护技术水平低和能耗低等优点。目前已被用于处理各种类型的废水。它是由基质、植物和微生物构成的复合系统,其中,微生物在人工湿地系统净化污水过程中发挥着重要作用。从人工湿地微生物群落多样性和功能性两方面对人工湿地系统中微生物的研究进展进行了概述,进而对人工湿地微生物研究的前景进行了展望,旨在为该领域的相关研究提供资料和借鉴。

Constructed wetland is a sewage processing technology engineering developed rapidly since the late 1970 s. It has theadvantages of low investment,low running cost,low-level maintenance technology and low energy consumption. Currently,it has been usedto process various types of waste-water. Constructed wetland is a composite system composed of matrix,plant,and microorganism,in whichmicroorganisms play an important role in the process of waste-water purification. This paper introduces the research progress of microorganismsin the constructed wetland system from the diversity and function of microbial community,and further gives the research prospects in this field,aiming at providing information and reference for relevant researches in this field.
