自1974年以来,氯化消毒水中出现的一个突出问题就是在处理水中生成了致癌物质—三卤甲烷、四氯化碳等有机氯化物。为此提出了如何降低、去除氯化消毒水中的副产物,使之达到饮水标准,以及开发研究新的饮水消毒剂成了近年来国外饮水消毒研究中的一个主要课题。一、水的氯化消毒目前世界上绝大多数城市自来水都用氯消毒。多年来的历史已经证明,氯是一种效果很好的饮水消毒剂,在保证人体健康方面起了很大的作用,这是大家公认的。然 A prominent problem that has emerged in chlorinated water since 1974 is the formation of organic chlorinated carcinogens such as trihalomethanes and carbon tetrachloride in water. Therefore, how to reduce and remove by-products from chlorinated disinfection water to make them reach the standard of drinking water and to develop and research new drinking water disinfectants have become a major issue in the research of drinking water disinfection abroad in recent years. First, the chlorination of water disinfection At present, most cities in the world tap water are disinfected with chlorine. Over the years, it has been well established that chlorine is a very effective drinking water disinfectant and plays a very important role in ensuring human health. Of course
