摘　　要：为了探讨水合二氧化锰对于实际水源水中有机污染物的去除效果，通过实验室烧杯混凝试验，以松花江水源水为研究对象，以高锰酸盐指数（CODMn）、DOC、UV254为指标，研究了高锰酸钾还原法制备的水合二氧化锰对实际水源水中有机污染物的去除效果，并对水合二氧化锰去除有机物的机理进行了初步探讨。结果表明：当水合二氧化锰投加量很低时（1～3mg／L），其对松花江水源水中有机污染物的去除已很显著，并且CODMn、DOC、UV254三种指标具有良好的相关性。由此得出结论：与传统混凝剂相比，该种水合二氧化锰表现了良好的去除实际水源水中有机污染物的效能。实验结论对于水处理工程实际具有重要意义。In order to study the effect of removing micro -organic pollutants in source water by hydrous manganese dioxide, with using CODMn ,DOC and UV254 as the index, the jar tests were conducted to evaluate the effect of removing organic pollutants in Songhua River by hydrous manganese dioxide which was prepared by reduction of potassium permanganate. The possible mechanism of removing organic matter by hydrous manganese dioxide was inves- tigated. The results showed an obvious effect of removing organic pollutants in Songhua River water by hydrous manganese dioxide in low dosage （ 1 - 3mg/L）. The index of CODM,, DOC and UV254 had excellent correlation. It was concluded that this kind of hydrous manganese dioxide had better effect of removing micro - organic pollutants compared with traditional coagulants. The conclusion would be important to practical engineering of purifying water.
