摘　　要：目的了解杭州市某开发区生活饮用水水质卫生状况,为有效监管饮用水卫生安全提供科学依据。研究对象为2009年杭州市某开发区市政供水单位出厂水、管网末梢水和二次供水水质监测样本。方法 2009年对杭州市某开发区出厂水、末梢水和二次供水按照国家标准进行采集、检测和评价。结果 162件水质检测样品的总合格率为92.59%,其中出厂水、管网末梢水、二次供水水质检验合格率分别为100%,92.11%,92.50%。管网末梢水水质检测不合格项目主要为细菌总数、总大肠菌群、耐热大肠菌群、浑浊度;二次供水水质检测不合格的项目主要为总大肠菌样、菌落总数。结论为有效改善饮用水水质卫生状况,应改造陈旧的管网和二次供水系统,并做好水质消毒工作。Objective To analyze the health quality of drinking water in Hangzhou certain development area,and provide the coping strategies of supervision.Methods All of the samples from water supply,tap water and secondary water supply in 2009 were selected as research objects in this study.According to the national health standards,the samples of water supply,tap water and secondary water supply in Hangzhou certain development area were collected,tested and evaluated.Results The results showed that the total qualification rate of 162 samples was 92.59%,and the qualification rates of samples from water supply,tap water and secondary water supply were 100%,92.11%,92.50% respectively.The disqualification items of tap water were aerobic bacterial count,total coliform group,heat-resistant coliform group and opacity,but the disqualification items of secondary water supply were total coliform group and aerobic bacterial count.Conclusion This investigation suggests that the old network of pipes and secondary water supply system should be reconstructed and drinking water be sterilized in order to improve the drinking water quality.
