MBR平板膜技术在医院污水处理中的应用研究

Research on the Application of MBR Flat Membrane Technology in Hospital Wastewater Treatment

在当前的环保形势下,医院污水处理越来越受到各个医院后勤部门的重视。医院污水处理站的设计在整个医院的规划中属于末端环节。如何减少医院污水处理站的占地面积,缓解医院用地紧张的局面是当前的一项重要课题。在此背景下,探讨一种新型水处理技术在医院污水处理中的应用很有必要。MBR膜处理工艺作为一种由活性污泥法与膜分离技术相结合的新型水处理技术,应用于医院污水处理,是通过独特的泥水分离技术,大大提高了污水中活性污泥的浓度,并提高了污水处理负荷,缩短了污水处理的生化反应时长,从而减少了污水处理站的占地面积[1]。

In the current environmental protection situation,hospital sewage treatment is increasingly receiving attention from various hospital logistics departments.The design of hospital sewage treatment stations is an end stage in the entire hospital planning.How to reduce thefloor area of hospital sewage treatment stations and alleviate the shortage of hospital land is an important issue today.In this context,it is necessary to explore the application of a new water treatment technology in hospital wastewater.The MBR membrane treatment process,as a new type of water treatment technology that combines activated sludge method and membrane separation technology,is applied in hospital sewage treatment.Through its unique sludge water separation technology,it greatly increases the concentration of activated sludge in sewage,improves the sewage treatment load,and reduces the biochemical reaction time of sewage treatment,thereby reducing the footprint of sewage treatment stations[1].
