摘要: 粉煤灰基微滤膜是一种新型的廉价陶瓷膜，本文将其用于生活污水的三级处理。考察了跨膜压差和膜面流速等对渗透通量的影响，利用孔堵模型对膜污染过程进行了污染机理分析。膜过滤出水达到了生活杂用水的标准。发现膜污染的机理主要是滤饼层过滤机理。
Abstract: Fly-ash based microfiltration membrane is a new kind of low cost ceramic membrane. It was used to treat the secondary effluents. The effects of transmembrane pressure and cross flow velocity on the permeation flux were inves-tigated. The membrane fouling mechanism was analyzed based on the pore blocking model. The product water met the requirements of Miscellaneous Domestic Water Quality Standard. It was found that the membrane fouling originated from cake filtration.
