摘　　要：随着我国经济不断发展,工业用水、居民用水量呈现大幅度地增长,我国面临着非常严重的缺水问题。常见的用混凝沉淀/砂滤/生物活性炭-消毒-出水深度处理二级出水,虽然出水水质满足相关指标,但出水中可能形成一些难降解小分子物质,对于水质要求比较高的行业,暂时还达不到相应的出水水质条件。综合阐述了膜处理技术的基本原理、特征及发展状况,并对该技术在污水深度处理回用过程中所面临的问题展开了探讨,最后进行了展望分析。希望膜处理技术能够得到进一步的优化和发展。With the continuous development of my country's economy,the consumption of industrial water and residential water has increased substantially,so my country is facing a very serious water shortage problem.The common use of coagulation sedimentation/sand filtration/biological activated carbon-disinfection-effluent advanced treatment of secondary effluent,although the effluent quality meets the relevant indicators,some refractory small molecular substances may be formed in the effluent,for industries with high water quality requirements,cannot meeting the corresponding effluent quality conditions.This paper comprehensively expounds the basic principle,characteristics and development status of membrane processing technology,and discusses the problems faced in the process of advanced wastewater treatment and reuse.Finally,this paper makes a prospect analysis.It is hoped that the membrane processing technology can be further optimized and developed.
