摘要:
目的 了解宁夏城市饮用水氯化消毒副产物的含量水平,初步探讨三卤甲烷含量与pH 值、耗氧量的关系。方法 分别对2014-2016年宁夏5市城区12家自来水厂出厂水进行检测,对主要氯化消毒副产物三卤甲烷(THMs)、耗氧量、游离氯和pH值等指标进行监测。结果 生活饮用水中所有三卤甲烷类副产物检测结果均未超过国家饮用水卫生标准限值;液氯消毒的饮用水中各三卤甲烷检出率均高于复合二氧化氯消毒的饮用水(P均<0.01);生活饮用水中三氯甲烷、二氯一溴甲烷、一氯二溴甲烷含量与pH值、耗氧量均有线性关系(P<0.05)。结论 使用二氧化氯消毒可有效减少三卤甲烷的产生。
Abstract:
Objective To understand the content of chlorinated disinfection by - products in urban drinking water in Ningxia, and to explore the correlation between the content of trihalomethanes and pH value and oxygen consumption. Methods THMs, oxygen consumption, free chlorine and pH value of the main disinfection by - products were monitored. Results All the indicators of trihalomethanes were not exceeding the national drinking water health standard.The detection rate of trihalomethane in drinking water disinfected by liquid chlorine was higher than that in drinking water disinfected by compound chlorine dioxide(P<0.01). Trichloromethane, dichloromonobromomethane and monochlorodibromomethane have linear relationship with pH value and oxygen consumption(P<0.05). Conclusion The use of chlorine dioxide disinfection can effectively reduce the production of trihalomethanes.
