“随着社会发展,水源受到严重的污染,自来水虽经加工,但很难全面达到安全的各项指标;中国自来水厂大都使用氯为主要消毒剂,有机物在氯化消毒过程中与氯发生化学作用,不但增加氯损耗影响消毒结果,还可能生成多种对人体有害的氯化消毒副产物,其中大部分对人体健康构成潜在威胁;同时城市管道的腐蚀老化,严重影响着居民的饮用水安全。” “With the development of society, water sources are seriously polluted. Although tap water is processed, it is difficult to fully achieve all safety targets. Most of China’s waterworks use chlorine as the main disinfectant, and organics are chlorinated with chlorine. Chemical actions not only increase the loss of chlorine, affect the disinfection results, but also generate a variety of chlorination disinfection by-products that are harmful to the human body, most of which pose a potential threat to human health; at the same time, the aging of urban pipelines seriously affects the residents’ drinking water.
