  • An Experiment Study on Slime Water Closed using Air Flotation

    PENG Chang-sheng 1, MENG Hong 1, ZHU Fen-mei 2(1 Beijing Science and Technology University,Beijing 100083,China; 2 Hongzhou Environment Protection Institute,CCRI,Xiaoshan 311201,China)

    An effect comparison between air flotation and sediment method for slime water closed circle use was conducted. The result is shown that, the air flotation method is bettr obviously than sediment method in slime recovery especially when the concentration of slime water more higher or lower. However, the slime water can not accord with the discharge standard. If to do so, it should be further treatment.
