Effect of membrane module's configuration on the membrane separation activated sludge process was investigated using four different types of module, which are hollow-fiber, tubular, fixed plate and loosely fixed plate, in a laboratory-scale experiment.Volume of the aeration tank was 115L.The selected hollow fiber module was loop-type. A tubular type module was set vertically. A plate module was fixed only at four corners, which enables the module to wave in liquid.Tubular type module showed poor permeability bacause of clogging inside the module, while free-type plate module showed very good performance, which was caused by waving motions of the module keeping sludge off its surface.

采用中空纤维膜、管状膜、固定板膜和松固定板膜四种不同类型的膜组件，研究了膜组件配置对膜分离活性污泥过程的影响。曝气池容积115L。所选中空纤维模块为环型。垂直设置管状模块。平板模块只固定在四个角落，这使得模块可以在液体中波动。管式模块透气性差是因为模块内部堵塞，而自由板式模块透气性很好，这是由于模块的波动运动使污泥远离其表面造成的。
