铅锌选矿厂废水净化回用研究

摘要

介绍了采用“中和-机械混合反应-斜管沉淀-活性炭吸附”对铅锌选矿厂选矿废水进行处理后回用的方法,运行结果表明,采用该工艺处理后废水达到选矿工艺用水标准要求,由此不仅节约了大量新水,而且处理效率高,运行成本低,创造了良好的经济效益、社会效益和环境效益.%The method of wastewater reuse after treating wastewater from a lead-zinc ore benefieiation plant covering neutralisation, mix reaction by machinery, inclined lube sedimentation and activated carbon adsorption was introduced. The running results show that wastewater treated by the proposal technology has met the requirement of water standards for mineral processing technology, which saves a large amount of fresh water, and has created favorable economic, social and environmental benefits.
