摘要
目的了解宁海县农村生活饮用水卫生状况,为保障农村居民饮用水安全提供依据。方法全县除城区外设置70个水样监测点,分别于丰水期和枯水期进行出厂水、水源水和管网末梢水采样,按照GB/T 5750—2006《生活饮用水标准检验方法》标准进行检测分析。结果宁海县出厂水合格率为25.00%,水源水合格率为24.29%,管网末梢水合格率为25.71%。枯水期和丰水期管网末梢水差异无统计学意义(P>0.05),枯水期水源水和出厂水合格率高于丰水期。检测指标中合格率最低为耐热大肠菌群和总大肠菌群,末梢水、出厂水、水源水合格率依次为42.86%、44.29%、43.57%。结论宁海县农村饮用水水质急需提高,应推进农村改水建设,保护水源地不受污染,规范净化和消毒措施,保障农村居民生活饮用水安全。
Objective To understand the sanitary status of drinking water in rural areas of Ninghai County,so as to provide basis for ensuring the safety of drinking water in rural residents. Methods The samples of finished water,source water and terminal water from 70 monitoring points in rural area were collected and analyzed in accordance with the Determination Method of Drinking Water Standard（ GB/T 5750—2006）. Results The qualified rate of manufactured water in Ninghai county was25. 00%,the qualified rate of water source water was 24. 29%,and that for the end water of pipeline network was 25. 71%.There was no statistical significance in the difference in end water between dry season and high water period（ P〉0. 05）,and the qualified rate of raw water and the tap water in dry season was higher than that in high water period. The lowest qualified rate in the test indexes was the thermotolerant coliform group and the total coliform group. The qualified rate was only 42. 86%in the end water,44. 29% in tap water,and 43. 57% in source water. Conclusion The water quality of rural drinking water in Ninghai County is in urgent need of improvement. Water diversion construction in rural areas should be promoted to protect water sources from pollution,regulate purification and disinfection measures should be carried out to ensure the safety of drinking water for rural residents.
