摘要
针对选铜矿山工业废水COD含量高的特点,试验在选矿废水中添加化学试剂,达到去除COD的目的,最终使废水能够达标排放。试验结果表明在酸性条件下,废水中添加次氯酸钠溶液,可以有效去除COD,该方法操作简单,费用低。
According to the characteristics of high COD content in industrial wastewater of copper mine, chemical reagents are added into the wastewater to achieve the purpose of removing COD. So that the wastewater can reach the standard of discharge finally. The results show that adding sodium hypochlorite solution in acidic conditions can remove COD effectively. This method is easy to operate and low in treatment cost.
