目的了解泉州市生活饮用水卫生状况及其影响因素。方法对2012—2014年泉州市生活饮用水进行监测,以GB 5749-2006《生活饮用水卫生标准》评价分析。结果 2012—2014年共监测生活饮用水1 675份,总合格率64.2%。3年检测合格率分别为63.7%、66.6%和62.5%;分散式供水合格率仅27.7%,集中式供水合格率91.0%;枯水期和丰水期合格率分别为68.5%、60.6%。分散式供水的微生物指标超标严重,菌落总数、总大肠菌群和耐热大肠菌群的不合格率分别为38.9%、45.8%和30.3%;集中式供水中,游离余氯、浑浊度和铁超标较多。结论泉州市生活饮用水总体卫生质量有待提高,水质监管部门应加强监管。
Objective To understand the sanitary status of drinking water in Quanzhou and its influencing factors. Methods 2012-2014 Quanzhou drinking water monitoring, with GB 5749-2006 “drinking water health standards” evaluation analysis. Results A total of 1 675 drinking water were monitored during 2012-2014 with a total pass rate of 64.2%. The passing rate of 3-year inspection was 63.7%, 66.6% and 62.5% respectively. The passing rate of decentralized water supply was only 27.7% and the qualified rate of centralized water supply was 91.0%. The pass rates in dry season and wet season were 68.5% and 60.6% respectively. Microbial indicators of decentralized water supply exceeded the standard seriously, the total number of colonies, total coliform and heat-resistant coliform bacteria were 38.9%, 45.8% and 30.3%, respectively; in centralized water supply, free residual chlorine, turbidity and iron More than excessive.
