摘要
氯化法广泛应用于生活饮用水处理的消毒领域,但会产生多种对人体有害的消毒副产物(Disinfection By-Products,DBPs),如三卤甲烷(Trihalomethanes,THMs)和卤乙酸(Haloacetic Acids,HAAs)等.检测数据显示,水环境中,THMs浓度范围为0.14～458.00 μg/L,HAAs浓度范围为0.16～136.00 μg/L.因此,中国生态环境部、美国国家环境保护局和世界卫生组织等权威机构制定若干法规,以保护人类健康.一些技术也被开发出来,以去除水中DBPs及其前体物.目前,常用的DBPs去除技术有吸附法、高级氧化法、混凝法、膜过滤法和联合处理法等.采用吸附法时,水中DBPs的去除率可达 90%.
Abstract
The chlorination method is widely used in the disinfection field of drinking water treatment,but it produces various harmful Disinfection By-Products(DBPs)to the human body,such as Trihalomethanes(THMs)and Haloacetic Acids(HAAs).The detection data shows that in the water environment,the concentration range of THMs is 0.14～458.00 μg/L,and the concentration range of HAAs is 0.16～136.00 μg/L.Therefore,authoritative institutions such as the Ministry of Ecology and Environment of China,the Environmental Protection Agency of the United States,and the World Health Organization have formulated several regulations to protect human health.Some technologies have also been developed to remove DBPs and their precursors from water.At present,commonly used DBPs removal technologies include adsorption method,advanced oxidation method,coagulation method,membrane filtration method,and combined treatment method.When using adsorption method,the removal rate of DBPs in water can reach 90%.
