某铅锌矿选矿废水成分及其与COD关系探讨

Discussion on Relationship of COD and Compositions of Wastewater from Some Pb-Zn Mine

介绍了某铅锌矿选矿废水的基本情况。通过测定各选矿废水的COD及TOC,分析了选矿废水成分与COD的关系。研究结果表明,为了从源头上控制选矿废水的COD,宜对选矿药剂进行筛选,尽量选择对COD贡献小以及易降解的选矿药剂。

The situation about mineral processing of wastewater discharged by a certain Pb-Zn mine was briefly stated. Based on the measurement of COD and TOC of wastewater collected from different sites, the relationship between the compositions of wastewater and its COD measurement was analyzed. Results show that it is essential to optimize the reagent system so as to ensure a source control of wastewater COD, and it is strongly recommended to choose degradable reagents with little contribution to COD.
