摘要
目的了解雅安雨城区生活饮水水质卫生情况,为饮水卫生管理提供依据。方法水样采集、保存、运输、检测分析按照《生活饮用水标准检验方法》(GB/T 5750-2006)执行,水质分析结果按照《生活饮用水标准》(GB 5749-2006)判定。结果三年共检测水样488份,微生物指标合格率最低(总合格率为57.79%),城区饮水和农村饮水总合格率分别为91.91%和44.60%,差异有显著统计学意义(P<0.001);出厂水与末梢水总合格率分别为62.70%和52.87%,差异有统计学意义(P<0.05)。结论城区饮水各项指标总体良好,农村饮水合格率较低,末梢水合格率低于出厂水,因此农村应更新消毒净化设施,加强管网改造等基础设施建设。
Objective To understand the condition of dringking water quality of Yucheng District,Ya’an city and to provide management of dringking water with evidences. Methods Water sample collection,storage,transportation and examination analysis are consistent with Standard Examination Approaches of Dringking Water（ GB /T 5750- 2006）. Analysis on water quality is based on Standard of Dringking Water（ GB 5749- 2006）.Results In three years,488 samples were collected. Passing rate of microorganism was lowest（ total passing rate was 57. 79%）. Total passing rate of urban and rural area were 91. 91% and 44. 60%,respectively. The difference between the two areas was of statistical significance（ P 〈 0. 001）. Passing rate of finished water and tap water were62. 70% and 52. 87%,respectively. Their difference was of statistical significance.（ P 〈 0. 05）. Conclusions Indexes of urban dringking water are generally good while passing rate of dringking water in rural area is relatively low. Passing rate of tap water was lower than that of finished water. So disinfection and purification facilities should be updated and the construction of infrastructure such as pipe network should be strengthen in rural areas.
