| Abstract: | 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%. |
