摘要
利用高纯度高铁酸钾,进行了矿井水处理试验,结果表明:在简单的工艺条件下,高铁酸钾投加量在24 mg/L以上时,经处理的矿井水剩余CODcr小于6 mg/L;高铁酸钾浓度大于7 mg/L时,经处理的矿井水残余的总大肠菌群数小于3个/L,杀灭率可达98%以上;高铁酸钾投加量大于24 mg/L,可以使混凝后的矿井水浊度达到5 NTU左右。
Utilized the home - made pure K2FeO4 to do the beaker experiment of mine water treatment. The experimental result shows ： In the simple technics conditions, when the density of K2FeO4 is beyond 24mg/L, the remanent CODcr of treated mine water is less than 6mg/L. And the turbidity can reach 5NTU. When the density of K2FeO4 surpasses 7mg/L, the remained large intestine bacilli in treated mine water is less than 3MPN/L. The rate of killing is above 98%.
