膜生物反应器内泥水混合液可过滤性的研究

膜生物反应器是一种新兴的水处理技术，但目前膜造价较高，导致运行费用较高，因此，提高膜通量的各种技术措施具有重要的意义。文中引入静态泥水混合液过滤试验，通过对取自运转中ＭＢＲ的活性污泥混合液的过滤实验结果分析，着重阐述了影响活性污泥可过滤性的影响因素，并指出在维持ＭＢＲ的运行中，改善活性污泥性状是一个不可忽略的方面。

Study on Filterability of the Mixed Liquor in Membrane Bioreactor

Membrane bioreactor(MBR)is an advanced technology for wastewater treatment which has been developed rapidly.It is important to study the technology for improving the membrane flux because of the high membrane cost which leads to the high operation cost.A filtration experiment of mixed liquor taken from a running MBR was designed and used to analyze the factors which influenced the filterability of the mixed liquor.It was found that improving the nature of the activated sludge was one of the important aspects for the successful running of a MBR.
