膜分离技术中的MBR与RO组合工艺具有出水水质好、占地面积小、便于自动控制、运行稳定等优点。但在运行过程中，膜会发生不同程度的污堵，如何减缓膜污染的发生及让系统稳定高效的运行是膜法水处理技术面临的主要问题。通过优化生化系统的菌群结构，提高生化出水水质，可有效减缓MBR膜污染的发生，从而使生化+ MBR系统的整体运行效果大大增强；通过在MBR和RO之间增设汽水换热系统，可克服冬季低温对RO系统运行的影响，提高MBR + RO组合工艺的产水率，节省运行能耗。

The combing technology of MBR and RO possesses good water quality, accounts for a smal area of the land, is easy to automatic control and has a stable operation in membrane separation technique. But in the operation course, the membrane would cause the sludge blockage at the different degree. The main problem of the membrane process of water treatment technique is how to eliminate the occurrence of membrane polution and to maintain the operation of the system in a stable and high effect condition. By optimizing the bacterium group structure of bio-chemistry system and upgrading the water quality of bio-chemistry, the occurrence of MBR membrane pol ution can be efifciently eliminated, so that the whole operation effect of bio-chemistry+MBR system can be boosted up;by setting up the heat exchange system of ifzzwater between MBR and RO, impact of low temperature in Winter on RO system operation can be overcome, the generating water rate of the comb-ing technology of MBR + RO can be upgraded, the operation energy consumption can be saved.
