应用旋流絮凝法处理选矿废水

Beneficiation Wastewater Treatment by Whirling Flocculation

将１８ｍ 的浓缩机改为两级串联旋流絮凝沉淀池处理选矿废水， 达标率为１００ ％ ， 净化效率为９９８５ ％ ， 其它水质指标均低于国家废水排放标准， 浓缩机底部排污率由１５ ％ 提高到３１８９ ％ ， 还可获得１４３１４ 万元／

The up -to-standard rate of beneficiation waster treatment reaches 100% and the purification effectiveness scores 99 85% if change the 18m thickener into whirling flocculation sediment pool. Other water quality parameters are lower than the state wastewater discharge standard. The rate of sewage discharge at the bottom of thickener increases to 31 89%from 15%. An annual economic interest of over one million can also be obtained.
