摘要:
通过建立某城市生活饮用水中挥发性卤代烃的气相指纹图谱，获得了挥发性卤代烃的指纹特征，并分析了其在水源水、出厂水、末梢水及二次供水中的变化与水源水中前体物构成变化、水处理设施净化效率、水传输管路和设施老化的相关性，探讨了指纹特征在水中挥发性卤代烃污染特征分析和污染防控等方面应用的可行性。结果表明，该市生活饮用水中有5种未知风险的挥发性卤代烃或消毒副产物未纳入监测指标；水传输过程中挥发性卤代烃指纹特征的变化，可作为水源水中前体物构成改变、水处理设施净化效率下降及水传输管路和设施老化等问题的发现指征。
Abstract:
The fingerprint characteristics of volatile halogenated hydrocarbons were obtained by establishing the gas chromatography (GC) fingerprint of volatile halogenated hydrocarbons in the drinking water in a city. The correlation between the changes of fingerprint characteristics in source water, finished water, pipe end water, and secondary water supply and the variation of precursor composition in source water, the purification efficiency of water treatment facilities, and the aging of transmission mains and facilities was analyzed, and the feasibility of fingerprint characteristics in the analysis of volatile halogenated hydrocarbon pollution in water and pollution prevention and control was discussed. Five types of volatile halogenated hydrocarbons or disinfection byproducts with unknown risks in the drinking water of the city were not included in the monitoring index. The changes in fingerprint characteristics of volatile halogenated hydrocarbons during water transportation could serve as an indication of the alteration in precursor composition in source water, the decline in the purification efficiency of water treatment facilities, and the aging of water transmission mains and facilities.
