摘要
阐述了粗石英砂气水同时冲洗滤池,在污水深度处理中的适用性。通过絮凝沉淀过滤、直接过滤和微絮凝过滤三种处理工艺的试验,表明该滤池较常规滤池显示更好的性能。针对污水过滤中的问题广重点对滤料、反冲洗、滤料支持系统进行了讨论。
This paper expounds the adaptibility of coarse sand filter with simultaneous air and water backwash to tertiary filtration plant.Through tests on three different arrangement, namely:coagulation-sedimentation-filtration, direct filtration and mi-croflocculation,it has found that,coarse filter showed better performance than the common filters. According to the problems with wastewater filtration, filtering media,backwash and media support system are discussed mainly.
