目的了解2015年天津市蓟县居民生活饮用水的水质现状,为加强饮用水安全管理工作提供科学依据和技术支持。方法依据《生活饮用水标准检验方法》(GB/T 5750-2006)、《生活饮用水卫生标准》(GB 5749-2006)对蓟县城区和农村的210份生活饮用水水样进行检测和评价。结果蓟县2015年生活饮用水总体合格率为42.86%(90/210)。枯水期、丰水期的微生物指标合格率分别为66.67%和52.38%,合格率差异有统计学意义(χ~2=4.447,P<0.05);市政集中式供水合格率75.00%(15/20),农村集中式供水合格率43.42%(66/152),农村分散式供水合格率23.68%(9/29),不同供水方式合格率差异有统计学意义(χ~2=14.161,P<0.05)。结论目前蓟县居民生活饮用水的水质合格率较低,应大力推进饮用水安全工程建设,加强部门监管和水源保护,加大卫生知识宣传,确保居民饮用水安全。
Objective To understand the status quo of drinking water quality in Jixian, Tianjin in 2015, and provide scientific basis and technical support for strengthening the safety management of drinking water. Methods Based on “Standard Test Method for Domestic Drinking Water” (GB / T 5750-2006) and “Sanitary Standard for Drinking Water” (GB 5749-2006), 210 samples of drinking water in urban and rural areas of Jixian County were tested and evaluated. Results The overall qualified rate of drinking water in Ji County in 2015 was 42.86% (90/210). The passing rate of microbial indicators in dry season and wet season were 66.67% and 52.38%, respectively. The passing rate was significantly different (χ ~ 2 = 4.447, P <0.05). The municipal water supply passing rate was 75.00% (15/20) , The qualified rate of centralized water supply in rural areas was 43.42% (66/152), the decentralized water supply rate in rural areas was 23.68% (9/29), and there was a significant difference in the pass rates of different water supply ways (χ ~ 2 = 14.161, P <0.05) . Conclusion At present, the water quality of drinking water in Jixian County is low. The construction of drinking water safety project should be vigorously promoted, the departmental supervision and water source protection should be strengthened, publicity of health knowledge should be stepped up, and the drinking water safety of residents should be ensured.
