摘　　要：在浮选过程中,矿石选矿废水中的重金属离子具有较高的浊度,对水中的TP值造成了一定的影响。混凝沉淀-吸附法处理选矿废水能够有效去除水中的重金属离子、污染物及化学需氧量(COD)等。本文采过正交试验方法对处理条件进行了优化和改进,探讨了不同吸附剂投加量对矿石选矿废水处理效果的影响机理。During the flotation process,heavy metal ions in fluorite beneficiation wastewater have a high turbidity,which has a certain impact on the TP value of the water.The coagulation sedimentation adsorption method can effectively remove heavy metal ions,pollutants,and COD from fluorite beneficiation wastewater.The orthogonal experimental method was used to optimize and improve the treatment conditions.This article explores the mechanism of the influence of different adsorbent dosages on the treatment effect of fluorite beneficiation wastewater.
