混凝-吸附处理金矿选矿废水试验研究与工程实践

Experimental research and engineering practice of gold concentration waste water treatment with coagulation-adsorption method

针对某金矿选矿废水水质特征和选矿废水回用水质标准,采用胶体脱稳—絮凝沉降—吸附处理工艺进行试验,确定最佳药剂投加量和处理工艺流程,项目自2009年9月运行以来,系统运转正常,出水水质稳定。该技术具有工艺简单、投资省、运行费用低,处理效果好等优点,对类似的矿山废水处理具有一定应用推广价值。

In view of concentration waste water characteristics of a gold mine and reuse water quality standard of concentration waste water,a test was conducted using the process of colloid unstability-flocculating sedimentation-adsorption.The optimal agent amount and treatment process flow were determined.Since the operation of the project in Sep 2009,the system operation is normal,the treated water quality is stable.The technique has the advantages of simple process,low investment and operation cost and good treatment effect etc.,which is of certain popularization value to similar mine waste water treatment.
