摘　　要：概述了饮用水生物强化过滤工艺的研究进展,讨论了该工艺对污染物的去除效果及其影响因子,描述了滤层中贫营养微生物膜的特性,提出了有待进一步研究的问题.分析认为:生物活性滤池可有效地降低微污染水体中的浊度,并对有机物、氨氮、铁、锰等污染物质有较好的去除效果;滤料介质、空床接触时间、反冲洗水质和反冲洗方式等是主要影响因素;滤层中贫营养微生物生理生态特性、物化与生化的协同作用等有待深入研究.The pollutant removal effect of the enhanced biological filtration technique and its influencing factors were discussed, and the characteristics of oligotrophic microbe film in filters were described. Some problems for further study were put forward. It is demonstrated that the enhanced biological filtration can effectively reduce the turbidity of micropolluted water body and is of good effect in removal of organism, ammonia nitrogen, iron, manganese and other pollutants, and that the filter media, empty bed contact time, and backwashing, et al. are the main influencing factors. It is pointed out that the physiological and ecological characteristics of oligotrophic microbes and the coaction of physicalchemical and biochemical processes need further investigation.
