目的了解兰州市农村集中式供水现状,为兰州市进一步进行农村改水工作,制定农村饮水安全工程规划,保障农民身体健康提供科学依据。方法对兰州市38个农村集中式供水点基本情况进行现场调查,并进行水质抽样检测。调查的数据全部输入Excel数据库,率的比较采用SPSS13.0软件进行χ2检验,P<0.05为差异有统计学意义。结果本调查研究的38个供水点中79.0%的供水点未进行水处理,84.2%无任何消毒设备,未进行任何方式消毒;水质合格率为20.4%,以细菌学指标超标最为严重,菌落总数超标率高达65.8%;丰水期水质明显差于枯水期(P<0.05)。结论兰州市农村集中式供水水质卫生状况相当差,应加强农民群众饮水卫生知识的教育,保护水源不受污染,同时加强饮水的净化和消毒,加强水质监测。
Objective To understand the status quo of centralized water supply in rural areas in Lanzhou and to provide a scientific basis for further rural water change work in Lanzhou, formulation of rural drinking water safety project planning and protection of peasants’ health. Methods A total of 38 rural centralized water supply points in Lanzhou were surveyed on site and water samples were taken for sampling. Survey data were all entered into the Excel database, the rate of comparison using SPSS13.0 software χ2 test, P <0.05 for the difference was statistically significant. Results 79.0% of the 38 water supply points in this study were not treated with water, 84.2% were disinfected without any means and were not disinfected in any way. The qualified rate of water was 20.4%, with the most serious bacteriological indicators exceeding the total number of colonies The exceeding standard rate was as high as 65.8%; the water quality in wet season was significantly worse than that in dry season (P <0.05). Conclusion The water quality of centralized water supply in rural areas in Lanzhou is quite poor. Education of farmers’ drinking water hygiene knowledge should be strengthened so as to protect water source from pollution. At the same time, the purification and disinfection of drinking water should be strengthened and water quality monitoring should be strengthened.
