摘　　要：采用微絮凝连续过滤技术深度处理矿区生活污水,探讨了滤料粒径、厚度、滤速、砂循环速率及药剂投加量等因素对SS去除效果的影响。结果表明：粒径0.8-1.0 mm,滤床厚度1.0-1.2 m,滤速6-8 m/h,砂循环速率在2-4 mm/min,PAC投加量20-25 mg/L时,出水SS小于5 mg/L,去除率达到94.5%以上。Micro-flocculation Continuous sand filtration were used to treat mining area s domestic sewage,this study investigated the effect of filter material size,sand filter s depth;filtering velocity;sand circulation velocity as well as medicament dose on the SS removal.The results indicated that when the filter material size was bout 0.8-1.0 mm;the depth of sand filter was about 1.0-1.2 m;sand circulation velocity was about 2-4 mm/min;PAC dose was about 20-25 mg/L,the effluent SS was less than 5 mg/L,the removal rate arrived at 94.5%.
