摘　　要：通过对云南滇池地区某大型胶磷矿浮选厂的尾矿库溢流水进行化验,分析结果显示,虽然水质清澈,但废水中Ca2+、Mg2+等含量太高,直接利用这部分水会对正浮选指标造成影响,不能返回到生产中直接使用。根据废水水质,进行了水处理试验研究,最终通过双碱法处理后的回水用于试验流程中与清水流程进行对比试验,结果表明,试验指标良好,达到预期效果,可以用此方法对浮选厂生产废水进行处理后返回正浮选流程再利用,以提高回水利用率,降低污水处理成本,节约水资源。Through the chemical analysis of the overflow water from the tailing dam of a large cellophane flotation mill in Yunnan Dianchi area, and the result showed that the water was clear, but the Ca2＋, Mg2＋ content was too high to use in direct-flotation producing flow directly. Water treatment experimental study was carried out based on the wastewater quality, and finally the back water treated with the double-alkali method used in the direct flotation as good as with clean water. So flotation mill wastewater treated with the double-alkali method t can reuse in direct flotation flow, and to improve the utilization rate of return water, reduce the cost of iffluent treatment, also save the water resourse.
