SMBR法处理印染废水的膜污染减缓方法研究

The Research on Slowing Down Membrane Fouling in a Submerged Membrane Bioreactor

针对SMBR法处理印染废水膜污染进行研究,从减缓膜污染的角度出发,通过实验得到了针对实验系统的膜污染的几个影响因素,确定了系统的临界压力和临界通量,并证明在临界压力和通量下膜污染明显减缓;膜组件倾斜于30°放置,压力增长缓慢;系统在临界压力0.015 MPa左右进行空曝气时,膜通量恢复了43%。

The study on membrane fouling in a submerged membrane Bioreactor,starting at the side of slowing down the Fouling,get the Influencing factors by research and get the sub-sritical pressure and the sub-sritical flux.The membrane fouling slow down obviously under it.The running pressure ascended slower when the membrane is inclination at 30 degree.When we aerate at the sub-sritical pressure of 0.015 MPa,the flux resumed 43%.
