膜分离技术在城镇废水处理的应用进展研究

随着社会的发展,城镇废水污染物成分越来越复杂,可生化性差,而城镇污水处理厂污染物排放标准不断提高,这对城镇废水处理技术提出了新的要求。膜分离与生物法联用处理技术是污水深度处理的有效途径,得到越来越广泛的应用。本文简述了膜分离技术在在城镇废水处理领域的应用进展,对比分析了膜生物反应器、连续膜过滤、浸没式膜过滤、双向膜过滤等四种膜过滤技术的应用特点。

With the development of society,the pollutant components of urban wastewater are more and more complex and have poor biodegradability.The pollutant discharge standards of urban sewage treatment plants have been continuously improved,which puts new demands on urban wastewater treatment technology.Membrane separation and biological treatment technology is an effective way for advanced treatment of sewage,and has been widely used.In this paper,the application progress of membrane separation technology in the field of urban wastewater treatment is briefly described.The application characteristics of membrane membrane bioreactor,continuous membrane filtration,immersion membrane filtration and two-way membrane filtration are compared and analyzed.
