【摘要】 文章详细介绍了饮用水水源以及处理过程水质存在的潜在环境风险,水源特性、处理工艺、消毒剂种类、当地气候等原因决定了饮用水消毒副产物的生成量,特别指出氯化消毒所导致的消毒副产物的毒性及对人体健康产生的重大影响,需要认识消毒副产物基本生成规律以及控制方法。哈尔滨市供水实践表明:更换液氯为次氯酸钠消毒剂并通过对消毒剂量和接触时间的控制,是解决饮用水消毒副产物的一条有效途径。更多还原

【Abstract】 This paper introduces in detail about drinking water source and the potential environmental risks of water quality in the process of drinking water treatment. The amount of disinfection by-products produced in drinking water is determined by water source characteristics, treatment process, types of disinfectants and local climate, especially points out the toxicity of disinfection by-products caused by chlorination and its significant impact on human health, and it is necessary to understand its basic generation rules and control methods. The practice of Harbin water supply shows that replacing liquid chlorine with sodium hypochlorite disinfectants, controlling the disinfection dose and contact time is an effective way to solve the disinfection by-products of drinking water.更多还原
