目的加强农村饮水安全工程卫生学评价和水质卫生监测工作,探索建立水性疾病评估、预测体系。方法 2009年对定西市7县区的农村饮水安全饮水工程水水质进行了调查监测,通过查阅资料、现场查看与调查、电话核实补充等方式,填写国家制定的统一调查表。监测供水工程基本情况,水样的采集与监测等。结果农村安全饮水工程地面水水源占55.56%,地下水为水源的工程比例44.45%。工程设计采用地下水直供方式的比例较大,设计采用完全处理的工程比例较小,部分处理的工程比例较大。全市农村饮水安全工程的水质总体合格率为50%。结论通过监测,证明市农村饮水安全工程水质合格率很低,水质卫生存在着很大问题。
Objective To strengthen the hygienic evaluation of drinking water safety in rural areas and the monitoring of water quality and hygiene, and to explore the establishment of an assessment and prediction system for waterborne diseases. Methods In 2009, the water quality of rural drinking water safety drinking water project in 7 counties and districts of Dingxi City was investigated and monitored, and the unified questionnaire formulated by the state was filled in by means of access to information, on-site inspection and investigation, telephone verification and supplementation. Monitoring the basic situation of water supply project, water sampling and monitoring. Results 55.56% of the surface water sources for rural safe drinking water projects and 44.45% of the groundwater-sourced water projects. In engineering design, the proportion of direct groundwater supply is large, and the proportion of projects that are designed to be completely treated is relatively small, and the proportion of partially treated projects is relatively large. The city’s rural drinking water safety project of the overall pass rate of 50% water quality. Conclusion Through monitoring, it is proved that the passing rate of water quality in rural drinking water safety project in the city is very low, and there is a big problem in water quality and hygiene.
