摘　　要：选择细菌、大肠杆菌、氯仿、苯并（a）芘四项指标，对比二氧化氯和氯作为饮水消毒剂对各项指标的影响．结果表明，二氧化氯投加剂量低于氯；二氧化氯对水中致癌性物质苯并（a）芘有明显的降解作用，而氯则没有；加氯是产生氯仿的主要原因，而二氯化氯则不产生致癌致岐变的氯仿．Contrasts chlorine dioxide (ClO2) with chlorine (Cl2) on parameters of total bacterianumber, colon bacillus number, chloroform, benzpyrene in disinfected drinking water. The resultshows that the lower dosage of chlorine dioxide can be used than that of chlorine. Chlorine dioxidecan degrade benzpyrene effciently while chlorine can not. Chlorine dioxide used as disinfectant cannot produce chloroform which can cause cancer and deformity. Chlorine dosage and otherparameters such as pH, persistent time and reaction temperature can influence chloroformconcentration in drinking water.
