摘　　要：结合沿淮某给水厂的上向流复合滤料生物滤池工艺(UBF),对其分别与压力式、浸没式中空纤维超滤膜组件联用进行研究,并与水厂现有的快滤池进行对比。结果表明:两种类型的超滤膜组件,均能有效去除生物滤池出水中的颗粒污染物,可最大限度消除生物滤池存在的微生物泄露风险。与压力式超滤膜相比,浸没式超滤膜运行平稳、维护便捷,化学清洗频率大幅降低,运行4个月内产水衰减率始终低于5.0%,表现出良好的抗微生物污染性能。虽然快滤池对颗粒物的控制效果不及超滤膜,但仍可与消毒环节协作确保出厂水安全性,且>95%检测天数的滤后水浊度≤0.3NTU。The performance of up-flow biological filter（UBF）was studied in different combination with hollow-filter ultrafiltration membrane（UFM）and submerged ultrafiltration membrane（SUFM）in a water treatment plant along Huai River.In addition,its performance was also compared with that of a current rapid filter in this water treament plant.The results showed that particulate contaminants in biofilter effluents were effectively removed by both types of UF membrane combinations.The risk of microbes leaking out from UBF could be eliminated in each combination system.In contrast with UFM,the SUFM could run stably with a significantly reduced chemical cleaning frequency and easy maintenance.Moreover,the permeate flux decline rate of SUFM after four moths running was less than 5.0%,indicating excellent capability of resistance to biofouling.Although rapid sand filter was not as high effective as UF membrane in removal of particulate matter,it could cooperate with disinfection process to secure the sanitation of produced water from water plant and beyond 95%of the daily filtrates turbidity was lower than 0.3NTU.
