MBR处理印染废水中膜的污染及清洗研究

Membrane Fouling and Cleaning in the Dyeing Wastewater Treatment

印染废水组成复杂、色度大、难于生物降解,传统的污水治理方法处理效果不理想,所以印染废水的处理一直是企业和科研机构关注的一个难题。针对水解酸化-好氧膜生物反应器工艺系统在运行过程中膜污染的情况,着重分析膜通量和膜阻力的变化,提出几种膜清洗的方法。

Aiming at membrane fouling during the hydrolytc acidifying-aerobic membrane bioreactor system in operation,the article puts forward some methods of membrane cleaning through analysing the change of e flux and resistance of the membrane.
