膜—生物反应处理工艺中微生物对系统的影响

The Effect of Microorganism on System in Membrance-biology Reactor Craft

膜—生物反应器是近年来污水处理研究的热点,但受膜污染因素的影响,使其在实际应用中发展缓慢。由于膜—生物反应器的运行机理不是在生物反应器和膜组件的基础上简单叠加,并且由于生物特性和种类的改变,因此对系统的影响也不同于传统的活性污泥法。由于其独特的运行方式使微生物种类、数量发生变化,微生物在膜—生物反应器中不仅仅只起到去除有机物和脱氮、除磷的作用,对系统的运行也产生了一定的影响,尤其是对膜污染的影响。该文从微生物角度对其进行阐述,以期为膜污染治理提供一份参考。

The membrane-biology reactor was hot spot of the sewage treatment research in the recent years, but factor influence of the membrane pollution causes it to develop slowly in the practical application. Because the membrane-biology reactor movement mechanism is not adding in the biological reactor and in the membrane module foundation the simple superimposition, as a result of biological characteristic and type change, the influence is also different in the system of the traditional active sludge law. Because its unique movement way causes the microorganism type, the quantity have changed, the microorganism not only plays in the membrane-biology reactor removes the organic matter and remove Nitrogen, e- liminates the phosphorus, has also had the certain influence to the system movement, in particular it is important in membrane pollution influence. This article carries on the elaboration from the microorganism angle, and hope that provides a ref- erence that take the evidence for the membrane pollution government.
