【摘要】：目的了解2014年安徽省农村生活饮用水卫生监测状况,为加强安徽省农村饮用水水质监测提供科学依据。方法以全省所有涉农县(区)的60%乡镇为监测点,按照《生活饮用水标准检验方法》(GB/T5750-2006)中有关规定进行水样的采集和检测,共采集6 152份水样,监测18项指标,按《生活饮用水卫生标准》(GB5749-2006)为评价依据。结果安徽省2014年水质合格率为57.1%,其中集中式供水水质合格率分别为58.7%,学校自建设施水质合格率为48.6%,分散式供水水质合格率为36.5%。以溪水为水源的水样合格率(37.5%)最低,江河(61.7%)、湖泊(64.3%)次之,水库(66.9%)最高;以浅井为水源的水样合格率(37.0%)最低,深井(58.5%)次之,泉水(69.4%)最高。全省农村水质单项指标合格率较低的前5项指标分别是:游离性余氯、二氧化氯、总大肠菌群、耐热大肠菌群和菌落总数,其水质合格率分别为53.6%、72.8%、75.0%、85.0%和91.5%。结论农村饮用水水质合格率偏低,尤其是分散式供水,存在安全卫生较大隐患。
[Abstract]:Objective to investigate the sanitary monitoring of drinking water in rural areas of Anhui Province in 2014 and to provide scientific basis for strengthening the monitoring of drinking water quality in rural areas of Anhui Province.Methods A total of 6 152 water samples were collected from 60% villages and towns in all agricultural counties (districts) of the province, and 18 indexes were monitored according to the relevant regulations of GBT5750-2006.According to the Sanitary Standard of drinking Water GB5749-2006).Results the qualified rate of water quality in Anhui Province in 2014 was 57.1, among which the qualified rate of centralized water supply was 58.7, the qualified rate of school self-built facilities was 48.6, and the qualified rate of decentralized water supply was 36.5.The qualified rate of water samples with streams as the source of water is the lowest, the river is 61.7, the lake is 64.3), the reservoir is 66.9), the shallow well is the lowest, the deep well is 58.5) and the spring is 69.4).The first five indexes with lower qualified rate of single index of water quality in the whole province were: free residual chlorine, chlorine dioxide, total coliform bacteria, heat-resistant coliform group and total number of bacteria. The qualified rate of water quality was 53.6% 72.80.The water quality qualified rate was 85.0% and 91.5% respectively.Conclusion the qualified rate of drinking water quality in rural areas is low, especially the decentralized water supply.
