日前,多家媒体报道,清华大学研究人员历时3年在全国23个省、44个城市和城镇、155个点位采集了164个水样,水样涵盖水厂出厂水、家庭自来水和水源水,研究人员检测了自来水样中当前已知的全部9种亚硝胺类消毒副产物,检出率惊人。消息一出立即引发热议。氯消毒自1908年问世以来,是应用时间最久,应用范围最广的一种消毒方式。氯消毒剂容易获得,杀菌效果好,且氯可以有一定时间的残留量保证后续的消毒效果,因此成为迄今为止最重要的消
Recently, a number of media reports reported that Tsinghua University researchers collected 164 water samples from 155 sites in 23 provinces, 44 cities and towns across the country for 3 years. The water sample covers the factory water, domestic tap water and source water , The researchers tested all nine nitrosamine disinfection by-products currently known in tap water samples at an alarming rate. Immediately lead to a hot news. Chlorine disinfection since its inception in 1908, is the application of the longest, the most widely used disinfection. Chlorine disinfectant is easy to obtain, bactericidal effect is good, and chlorine can have a certain amount of residue to ensure the follow-up disinfection effect, it has thus become the most important consumer
