目的调查彭州市地震灾区饮用水水质状况,保障灾害后饮用水安全。方法灾后1个月内采集饮用水797份,按《生活饮用水标准方法》进行检测。结果乡镇以上水厂水源水检测合格率100%;乡镇以上水厂末梢水合格率89.2%,合格率较低的指标主要是消毒剂指标和微生物指标;分散式供水总体合格率27.8%,合格率低的指标是微生物指标。结论彭州市集中供水基本是安全的,分散式供水主要危险因素是微生物指标超标;彭州市应结合灾民的集中安置与灾区农村重建,做好集中供水设施的规划与建设,规范供水设施的管理,逐步实现灾区饮水安全。
Objective To investigate the status of drinking water quality in the earthquake-stricken area in Pengzhou and to ensure the safety of drinking water after the disaster. Methods A total of 797 drinking water samples were collected within 1 month after the disaster and were tested according to the standard method for drinking water. Results The qualified rate of water source water of township and above water plants was 100%. The passing rate of peripheral water of township and above water plants was 89.2%. The indicators of low pass rate were mainly disinfectant indicators and microbial indicators. The overall pass rate of decentralized water supply was 27.8% The low indicator is a microbial indicator. Conclusion Pengzhou centralized water supply is basically safe, and the main risk factor for decentralized water supply is excessive microbial indicators; Pengzhou should integrate the concentrated resettlement of victims and rural reconstruction in disaster-stricken areas to make planning and construction of centralized water supply facilities, standardize the management of water supply facilities, Gradually realize drinking water safety in disaster areas.
