| 摘 要： | 目的研究三氯甲烷（trichloromethane,TCM）在配水管网中的变化及其他水质指标对其生成量的影响.方法对我国北方某市市区配水管网饮用水中TCM、自由余氯、254nm紫外吸光度（UV254）、溴离子（Br-）等水质指标进行了监测.结果自由余氯与TCM在管网中的变化呈一定的负相关关系.经较长距离的输配后管网水中的UV254与TCM呈现一定的负相关关系.Br-含量较低的监测点,Br-含量的变化与TCM浓度呈一定的正相关关系;Br-含量较高的监测点,Br-含量的变化与TCM浓度呈一定的负相关关系.结论从水源污染、消毒剂的使用、出厂水水质稳定性和管网腐蚀4个方面,分析了问题的原因并提出了相应的措施.

| Abstract: | Objective To study the variety of trichloromethane(TCM)in distribution network,and the influence of other parameter to the production of TCM.Methods Detection was made on the parameters such as TCM,free chlorine,UV_(254) and Br~-in a northern city distribution network of China.Results Free chlorine had a good negative correlation with TCM.UV_(254) had good negative correlation with TCM after long distance distribution.The sampling sites with low Br~-concentration had positive correlation with TCM;on the contrary,sampling sites with high Br~-concentration had negative correlation with TCM.Conclusion Results of the experiments were analyzed and measurement correspond to the problems were provided from four aspect as the pollution of source;the sort of the disinfector;water stability of the outflow.and corruption of the distribution network. |
