摘要 在膜生物反应器L-R模型的基础上,修正了原模型的水力停留时间和污泥停留时间不分的问题,提出了新的数学模型,并研究了水力停留时间(HRT)和污泥停留时间(SRT)对膜污染和膜阻力的影响。结论为:胞外聚合物EPS水解产生的BAP随着SRT增长是导致膜污染的主要原因,且相对于HRT,膜污染对SRT更敏感。 A matematical model based on L-R model was develpoed for predicting the membrane fouling in membrane bioreactor. The olids retention time （SRT） and hydraulic retention time （HRT） was introduced into the new model to studing the influence of operational conditions on membrane fouling. The results showed that BAP accumulating in MBR is the main cause of the membrane fouling, and the membrane fouling is more sensitive to SRT than HRT.
