摘　　要：消毒是饮用水处理中特别重要的一步。随着工农业经济的飞速发展,水源中检测出大量种类复杂的有机污染物质,在消毒过程中这些有机物与消毒剂反应会产生一些对人体健康具有潜在危害的消毒副产物(DBPs),例如三卤甲烷、亚氯酸盐、溴酸盐等。因此,能否有效控制DBPs的产生成为了评价饮用水消毒质量效果的一项重要指标,而去除消毒副产物前体物是控制DBPs产生的关键。高铁酸盐作为一种绿色高效的新型水处理剂,具有强氧化还原能力,处理后的水中基本不会产生DBPs且能有效地抑制一些常见DBPs。文中综述常见的DBPs及前体物的种类、DBPs控制方法以及高铁酸盐在饮用水处理中对DBPs的控制。Disinfection is a particularly important part in drinking water treatment.With the rapid development of industrial and agricultural economy,a large number of complex organic pollutants have been detected in water source,resulting in the reaction of these organic substances with disinfectants during disinfection process to produce some disinfection by-products(DBPs)that are potentially harmful to human health,such as trihalomethanes,chlorites,bromates.Therefore,effective control of the production of DBPs has become an important indexes for evaluating the quality of drinking water disinfection,and the removal of disinfection by-product precursors is the key to controlling the production of DBPs.As a green and efficient new water treatment agent,ferrate has strong redox capacity.It does not produce DBPs in treated water and can effectively inhibit some common DBPs.The common DBPs and precursors,DBPs control methods,and the control of DBPs in drinking water treatment are studied.
