复合式膜生物反应器泥饼层中EPS含量及其与膜污染的关系

Monitor the quality of effluent and the concentration of extracellular polymerase substances（EPS） in the cake which attach to the hollow fibre membrane surface in the hybrid submerged membrane bioreactor(HSMBR) for 116 days. The relationship between the concentration of EPS and the membrane fouling have studied further; The results show that the quantity of EPS is linear to the TMP, and it is positive to the membrane fouling. The quantity of bound EPS is far higher than the soluble EPS. The concentration of EPS in the cake is one of the important factors which cause the membrane fouling.
