摘　　要：以四川威西矿区地下卤水为原料的制盐生产中的制盐母液为研究对象,针对其含有大量不同形态还原物的特性,分别采用双氧水处理法、次氯酸钠处理法以及漂白粉(或漂白精)处理法,逐一进行了不同处理条件下处理制盐母液中总还原性物质的化学处理研究,获得了几种不同化学处理方法的工艺技术参数及其处理效果,并做了综合性技术与经济评价。Taking the mother liquor in the salt making process whose raw material is the underground brine from Weixi mining area in Sichuan as the studying object and according to the characteristics of the different forms of reducing substance contained in the mother liquid, hydrogen peroxide treatment, sodium hypochlorite treatment, and bleaching powder （or fine chloride） processing method were used to carry out chemical treatment for total reduction material one by one in the mother liquor under different conditions.Finally,the processing parameters and the processing effect of several different chemical treatment methods were obtained, and a comprehensive techno-economic evaluation was made.
