错流过滤活性污泥过程中膜污染的研究
Research on Membrane Fouling in Cross-flow Filtration of Activated Sludge
摘要
Abstract
The critical flux of the membrane bloreactor with self-made filtration membrane was determined by stepwise increasing flux method. The experimental results show that the critical flux of the membrane bioreactor is 23. 8 L/( m2 · h ). The membrane fouling behavior in filtration of activated sludge was studied under the condition of subcritical flux. The results of model calculation show that the decrease of membrane flux accords with membrane resistance limit model, pore blocking resistance model and cake resistance model simultaneously. The analysis on filtration resistance distribution of the running membrane shows that the resistances caused by cake-forming and pore-blocking are the main parts of filtration resistance, which are 36. 64% and 61. 96% of the total resistance respectively, the resistance caused by membrane only accounts for 1.40% .关键词
