在膜生物反应器（MBR）中，以活性污泥为污染物，研究了微滤（MF）膜的污染特性。将活性污泥分离成悬浮固体和上清液。采用实验性浸没过滤系统研究了活性污泥及其各组分通过微滤膜的过滤性能。悬浮物是造成膜污染和流阻的主要因素。根据Hermia堵塞定律，将整个过滤过程分为两个阶段，每个阶段对应一种特定的结垢机理。这些分区用于分析不同空气流速下活性污泥各组分的过滤情况。空气强度的增加对上清液过滤的影响不大，但增加了悬浮物和活性污泥的过滤速率。对协同效应进行了分析，以描述过滤过程中的多个阶段。上清液和悬浮物之间的协同作用促进了膜污染。在初始过滤过程中，上清液对污垢的形成有很大的影响。
The fouling characteristics of microfiltration (MF) membranes were investigated with active sludge in a membrane bioreactor (MBR). The active sludge was separated into the suspended solids and the supernatant. The filtration through MF membranes of the active sludge and each component were investigated using an experimental submerged filtration system. The suspended solids were found to be the main factor causing the membrane fouling and flow resistance. The whole filtration process was divided into two stages according to the Hermia blocking law, with each stage corresponding to a specific fouling mechanism. These divisions were used to analyse the filtration of each component of the active sludge for different air flow rates. Increases in the air intensity had little effect on the supernatant filtration but increased the filtration rate of the suspended solids and the active sludge. The synergistic effects were analysed to describe the multiple stages in the filtration process. The synergistic effects between the supernatant and the suspended solids promoted the membrane fouling. The supernatant had a great effect on the fouling during the initial filtration process.
