某矿山井下矿井涌水净化处理工艺研究与应用

Investigation and Application on Purification Treatment Process of one Underground Mine's water inflow

目前铅锌采矿矿井涌水悬浮物的净化处理工艺仅为自然沉淀、过滤等,加之矿井涌水水量、水质变化大,悬浮物不能稳定达标排放,随着新环保法出台,也对企业环保管理提出了更高的要求。为解决某矿山井下矿井涌水悬浮物达标排放的问题,开展矿井涌水净化处理的研究与应用工作,结果表明采用混凝沉淀与自然沉淀联合处理的方式,能够降低矿井涌水中悬浮物浓度使其稳定达标排放。

At present,the purification treatment processes of the suspended solids from mine water of one lead-zinc mine only are natural sedimentation,filtration and so on,but the water volume of mine inflow is large,the water quality changes greatly,the suspended solids can not be discharged by standard steadily;the environment protecting management of the enterprise has the higher requirements along with the implementation of New Environmental Laws.The investigation and application on purification treatment process of one underground mine water is developed in order to solve the up-to-standard discharge of suspended solids of one underground mine water,the results show,the concentration of the suspended solids of one underground mine water can be reduced and stabilized by using of the joint method of coagulating sedimentation and natural sedimentation.
