目的了解大兴区生活饮用水氯化消毒剂主要副产物的种类及含量。方法选取大兴区2012年-2013年采用氯化消毒的生活饮用水进行分析,检测三氯甲烷、四氯化碳、氯酸盐、亚氯酸盐等指标。结果监测的4项消毒副产物指标中,三氯甲烷、氯酸盐、亚氯酸盐均全部合格,检测结果分别为0.000 1 mg/L~0.045 mg/L、0.010 0 mg/L~0.027 0 mg/L、0.010 0 mg/L~0.027 4 mg/L,这4项指标中只有四氯化碳有部分样品超标,检测结果为0.000 1 mg/L~0.275 mg/L,合格率为97.1%。结论针对大兴区生活饮用水氯化消毒剂主要副产物存在的问题提出合理化建议,达到减少健康危害的目的。
Objective To understand the types and contents of the major by-products of chlorinated disinfectants for domestic drinking water in Daxing District. Methods Daxing District, 2012 -2013 chlorinated disinfection of drinking water for analysis, detection of chloroform, carbon tetrachloride, chlorate, chlorite and other indicators. Results Among the four indicators of disinfection byproducts, all of chloroform, chlorate and chlorite were all qualified. The test results were 0.0001 mg / L ~ 0.045 mg / L, 0.010 0 mg / L ~ 0.027 0 mg / L, 0.010 0 mg / L ~ 0.027 4 mg / L, only some of the four indicators of carbon tetrachloride samples exceeded the test results of 0.000 1 mg / L ~ 0.275 mg / L, the pass rate was 97.1% . Conclusion Aiming at the problems existing in the major byproducts of chlorinated disinfectants for drinking water in Daxing District, reasonable suggestions are put forward to reduce the health hazards.
