    Health Security of Drinking Water in the Seventh National Peasant Games in Nanyang

      摘要
    • 摘要:
      目的 掌握有关接待宾馆等单位饮用水水质卫生状况, 为第七届全国农运会饮用水卫生安全做好保障。
      方法 对市政供水单位和比赛相关自建集中式供水单位进厂水、出厂水、末梢水进行监测, 对比赛相关的二次供水水质进行卫生监测, 水质分析按照《生活饮用水标准检验方法》(GB/T 5750-2006) 进行, 结果按照《生活饮用水卫生标准》(GB 5749-2006) 进行分析、评价。
      结果 共监测737份水样, 水质总合格率为85.89%, 市政供水水质好于二次供水和自建集中式供水水质。单项指标检测以游离余氯、菌落总数、耗氧量、总大肠菌群、耐热大肠菌群合格率较低, 分别为87.51%、94.03%、96.07%、97.01%、98.51%。
      结论 南阳市饮用水水质合格率较高, 整个南阳农运会期间未发生因饮水引起的水质污染事件, 确保了南阳农运会的饮用水卫生安全。微生物超标和消毒剂余量不足是影响水质不合格的主要原因, 有关单位应加强建设和管理, 以保障饮用水卫生安全。

       

      Abstract:
      Objectives To investigate the quality of drinking water in relevant hotels and other units and to provide security for drinking water in the Seventh National Peasant Games.
      Methods Monitoring the quality of water from municipal centralized water supplies, self-constructed water supplies and secondary water supplies. The water samples were tested according to the Standard Examination Methods for Drinking Water (GB/T 5750-2006), and the results were analyzed and assessed according to the Standards for Drinking Water Quality (GB 5749-2006).
      Results The qualified rate of 737 tested water samples was 85.89%; the quality of municipal centralized water supply was better than that of self-constructed central water supplies and secondary water supplies. The qualified rate for residual chlorine was 87.51%, for the total number of colonies was 94.03%, for oxygen consumption was 96.07%, for total coliforms was 97.01% and for themotolerant coliforms was 98.51%.
      Conclusions There was a high qualified rate for drinking water in Nanyang, and the main factors causing disqualification of drinking water were residual disinfectants and microbiological indices. Construction and management should be strengthened in order to protect the safety of drinking water.
