摘要
采用微絮凝连续过滤技术深度处理矿区生活污水，当滤料粒径采用0．8～1．0mm，滤床厚度1．2m，滤速6～8m／h，砂循环速率在4mm／min，PAC投加量20mg／L，PAM投加量0.3mg／L时，出水SS小于5mg／L，去除率达到94．7％以上，其它各项指标达到并优于建设部《生活杂用水水质标准》（CJ25．1—89）要求，可以实现中水回用。
Micro-flocculation continuous sand filtration were used to treat mining area＇s domestic sewage. The resuits indicated that the size of filter material was bout 0.8 - 1.0mm; the depth of sand filter was about 1.0 - 1. 2m; sand circulation velocity was about 2 -4mm/min; PAC dose was about 20 -25mg/L, the effluent-SS was less than 5mg,/L, the removal rate arrived at 94.5%.
