目的评价福建铁路辖区集中式给水的水质卫生状况,为卫生监督提供依据。方法对2000—2011年福建铁路辖区集中式给水的水质监测资料进行分析。结果水源水、出厂水和管网末梢水的总合格率为60.6%、84.7%和74.5%,各年度水源水、出厂水和管网末梢水合格率差异无统计学意义;管网末梢水细菌总数、浑浊度和铁合格率均<90%。供管水专业部门的出厂水和管网末梢水总合格率高于非供管水部门。结论 2000—2011年福建铁路辖区生活饮用水水质状况总体稳定。管网末梢水水质状况受管网影响较大。专业化的生产管理有助于饮水安全。
Objective To evaluate the sanitary status of centralized water supply in Fujian railway area and provide the basis for health supervision. Methods The water quality monitoring data of centralized water supply in Fujian Railway from 2000 to 2011 were analyzed. Results The total qualification rates of water source, ex-factory water and pipe-end water were 60.6%, 84.7% and 74.5%, respectively. There was no significant difference in the qualified rates of water in the source water, ex-factory water and pipe network in each year. The total number, turbidity and iron pass rate were <90%. For the professional water supply pipe factory water and pipe end of the total qualified rate of water than non-pipe water sector. Conclusions The water quality of domestic drinking water in Fujian Railway Area from 2000 to 2011 is generally stable. Pipeline water quality peripherals affected by the larger network. Professional production management contributes to drinking water safety.
