The effect of coagulant, pre-oxidation and charcoal absorption on the water comprehensive toxicity by applying luminescent bacteria as the fast detection in drinking water treatment process were studied . The results showed that relatively good result had been a-chieved in the application of chlorine dioxide pre-oxidation (0.4 mg/L) + polymeric aluminum chloride ( PAC) (40 mg/L) + activated carbon adsorption (20 mg/L) + sand filtration. The general organism toxicity index of water that had been optimized treated conformed to the state standards and others were excelled.%研究了以发光细菌检测法做为生物毒性快速检测的方法,测定饮用水处理过程中加入的絮凝剂、预氧化剂、活性炭等对水质综合毒性的影响.研究结果表明采用二氧化氯(0.4 mg/L)预氧化+聚合氯化铝(40 mg/L)混凝沉淀+活性炭(2.0 mg/L)吸附+石英砂过滤组合工艺对原水进行处理有比较好的效果.通过上述组合处理工艺原水,生物综合毒性指标完全符合限值要求,且其他各项指标均优于国家标准.
