摘　　要：采用烧杯试验考察了投加高铁酸钾强化混凝去除矿井水中铅、镉、铁、锰的效果。结果表明,高铁酸钾为30 mg/L时,混凝沉淀对低浓度矿井水中铅、镉、铁、锰的去除率分别约为55%、28%、93%、54%;高铁酸钾对模拟高浓度矿井水中铅、镉、铁、锰的去除率随pH的升高而提高,pH 8～10范围内对铅、镉、铁、锰有较好的去除效果,去除率可分别达到约95%、61%、97%和92%。处理后的矿井水中重金属含量可以达到饮用水标准,这给矿井水提供了很好的利用前景。Beaker tests have been conducted to investigate the removal efficiencies of lead, cadmium, iron, manganese from mine water by potassium ferrate. The results show that when the concentration of potassium ferrate is 30 mg/L, the coagulation and sedimentation of lead, cadmium, iron, and manganese can respectively reach 55% ,28% ,93% and 54%. The removal rates of lead, cadmium, iron, and manganese increase with the increase of pH. When the pH of treated water is in the range of 8-10, the removal effects on lead, cadmium, iron and manganese are better, reaching 95%,61%,97% and 92%, respectively. Then, the heavy metal content of the treated mine water can meet the requirements of national drinking water standard, providing mine water with a very good applicable prospect.
