家庭常用处理方法控制氯化消毒饮用水中消毒副产物的研究进展

Review of Household Drinking Water Treatment with DBPs Control for Chlorinated Tap Water

饮用水消毒可有效去除水中病原微生物,但氯消毒剂可与水中的有机物、溴碘离子反应,在水处理厂和输水管网系统中持续生成对人体健康具有潜在危害的消毒副产物(DBPs)。家庭水处理方法是饮用水进入人体前的最后一道防线,可减少水中DBPs的含量及其对人体健康带来的不良影响,进一步确保饮水安全。文中对家庭常用的饮用水处理方法(烹煮操作处理和净水设备处理)及其控制水中DBPs的研究进展进行综述,为健康饮水提供科学建议,并对今后的研究方向做出展望。

Pathogenic microorganisms in water could be removed effectively by disinfection of drinking water,but chlorine reacts with natural organic matter,bromide and iodide in source water to generate unintended disinfection byproducts(DBPs)in drinking water treatment plant and distribution system.Those DBPs are potentially harmful to human health.Household water treatment method is the last protective barrier before drinking water enters human body for further ensuring the safety of drinking water,which can reduce the level of DBPs in drinking water and the related adverse effects on human health.Research progress of household water treatment methods(including boiling,cooking,and water purifier)and the practical suggestions for controlling DBPs formation by those methods are provided.In addition,the future research directions on DBPs control are prospected.
