矿井水回用处理中卤代烃生成及其去除

THE FORMATION AND REMOVAL OF HALOGENATED HYDROCARBONIN CHLORINATED MINING DRAINAGE

分析了中国煤矿矿井水消毒处理后出水中卤代烃含量高的原因，论述了煮沸曝气、吸附、化学氧化及超声空化效应去除水中卤代烃的过程，提出了超声联合Ｏ３氧化去除矿井水中卤代烃母体是克服投氯消毒产生卤代烃的有效办法。

The reason of high concentration of halogenated hydrocarbon (carbon tetra- chloride and trihalomethane ) in chlorinated mining dranaige is discussed. The method of boiling-aeration , absorption , chemical oxidation and ultrasonic cavitation to remove the halogenated hydrocarbon in water is described. The effect method to prevent halogenated hy- drocarbon from presenting in chlorinated mining dranaige is to remove halogenated hydrocar- bon precursors from coal mining dranaige by sonolysis and ozone.
