高锰酸钾和锰砂协同处理微污染水的实验研究

Treatment of Micro-Polluted Water by Potassium Permanganate and Manganese Sand

以微污染的黄河水为对象,研究了高锰酸钾和锰砂协同作用对其处理的机理和效率。结果表明,高锰酸钾对微污染水具有较好的处理效果与安全性。原水通过天然锰砂处理后,其COD降低了40%;加入高锰酸钾后,COD降低了80%,表明高锰酸钾对水中有机污染物具有良好的去除效果。

Micro-polluted Huanghe river water was chosed as the experiment subject and study on the mechanism and efficiency of manganese sand,potassium permanganate to deal with organic pollutants were conducted. The potassium permanganate is safe and effective to deal with micro-polluted water. When the water passes the manganese sand, its COD drops 40%. After injection of potassium permanganate, its COD drops 80%. Results indicated that the potassium had a good effect on the removal of the organic pollutant.
