摘　　要：随着工农业和化工技术的发展,越来越多的化学物质尤其是有机化合物进入到地表水中,使得氯消毒副产物大量生成,危害人体健康。本文通过生产实践,采取用预臭氧代替预加氯、投加活性炭吸附前体物质、优化消毒工艺等措施大大降低了出厂水中三卤甲烷的生成量,确保了饮用健康。With the development of agriculture and chemical engineering technology, more and more chemical substances especially organic compounds goes into the surface water. This result in a lot of chlorine disinfection by-products generate, and harms to human health. Trihalomethanes in the effluent greatly reduced through some production practice, such as using pre-ozonation instead of pre-chlorination, dosing active carbon to adsorb precursor substance, optimizing disinfection technology etc, which ensured drinking health.
