Abstract
Based on the different mine well water samples before and after coagulating sedimentation,the basic affecting parameters of coagulating sedimentation were investigated,such as the distribution characteristics of turbidity,suspended matter and pH etc.The key parameters of the treatment of mine well water by coagulating sedimentation were analyzed as well,which can provide reference for the technical indexes of uranium mine well water treatment.The results show that mine well water turbidity value is mainly concentrated in 100～300 NTU,suspended solids mass concentration is between 150～300 mg/L,pH is 7～8 and the ζ is negative.PAC is used as the best coagulant;the best addition does not exceed 60 mg/L.The best G of the mixture is between 25 s-1 and 40 s-1,the GT 0.9 × 103 ～ 1.7 × 103,The best G value of flocculation is 5.4～ 10 s-1,the GT is 5.6 × 103 ～ 12 × 103.Therefore,the parameters for treatment of uranium mine well water by coagulating sedimentation are recommended as the above value.关键词
