摘　　要：考察了磁性离子交换树脂(MIEX)预处理/常规处理/活性炭吸附组合工艺对湖泊源水中CODMn、THMs、浊度、藻类及Br-的去除效果。结果表明:在常规处理工艺前增加MIEX预处理后,对CODMn的去除率提高了32%,对藻类的去除率提高了9%,并可节约混凝剂投量约40%;MIEX预处理/常规处理/活性炭吸附联用工艺对CODMn的去除率接近90%,使三卤甲烷含量降低了约90%,可作为生产饮用水和直饮水的优选方案之一;MIEX能有效去除水中的溴离子,但对其去除率会随通水倍数的增加而下降,实际应用中通水倍数取800较适宜。The combined process of magnetic ion exchange resin （MIEX） pretreatment, conventional process and activated carbon adsorption was used to treat lake source water, and the removal efficiencies of CODMn, THMs, turbidity, algae and Br were investigated. The results indicate that： （1） After MIEX pretreatment, the removal rates of CODM,, and algae in conventional process are increased by 32% and 9% , and the coagulant dosage is saved by 40% ; （2） The removal rate of CODM, in the combined process approaches 90%, trihalomethane content is reduced by approximately 90%, and the combined process can be used as one of the options for drinking water and direct drinking water production; （3） MIEX can effectively remove bromine ion in the water, but its removal rate is decreased with increasing of bed volume （ BV, volume ratio of tested wastewater to resin） , and 800 BV should be taken in the practical application.
