废水的人工湿地处理

介绍了人工湿地废水处理技术的机理及优点.即人工湿地利用基质、微生物和植物这个复合生态系统的物理、化学和生物三重协调作用,通过过滤、吸附、共沉、离子交换、植物吸收和微生物分解来实现对废水的高效净化;具有出水水质稳定、对N,P等营养物质去除能力强、基建和运行费用低、技术含量低、维护管理方便、耐冲击负荷强、适于除去间歇排放污水等优点.

Constructed Wetland (CW) for Wastewater Treatment

This paper introduces the mechanisms and advantages of the constructed wetland (CW),that the wetland utilizes the triple coordination of the physical,chemical and biological functions of the base materials,microbes and plants and through the filtration,absorption,coprecipitation,ionic exchange,plant absorption and microbe microbial decomposition to realize the high-efficiency purification of the wastewater,and points out the advantages of CW such as the stable quality of the discharged water,the stronger ability of removing N,P and other nutrient substances,the lower construction and operation cost,the lower technical contents,the convenient maintenance and management,the higher impact resistant loads,and the proper removal of the intermittent discharge of the wastewater,etc.
