摘 要:了解甘肃省农村窖水水质状况及影响窖水水质的因素,为改善农村窖水水质提供实验室依据。随机抽取会宁县会师镇两区和兰州市榆中县两村120眼水窖作为研究对象,采取现场问卷调查和实验室水质指标检测结合的方法进行研究。问卷调查结果显示,水泥窖占80%,存水周期一般为6~10个月,水窖周围污染源广,43.3%的农户家禽散养;清洗频率低,66.6%的居民未进行过水窖清洗。水质检测结果显示,浊度、p H值和CODMn3项指标存在不同程度的超标现象,细菌学指标也存在超标隐患。甘肃省农村窖水存在安全隐患,部分指标超标严重,应做好安全防护,采取经济实用、简单有效、科学合理的净水设备和净水措施,改善农村窖水使用安全状况。To explore the pitwater quality and the factors that affect the quality of pitwater in the rural areas of Gansu Province,provide a laboratory basis for improving pitwater quality. 120 cellars in Huishi Town of Huining County and Yuzhong County of Lanzhou were randomly selected as research objects. The spot investigation and laboratory water quality testing were used to study the water cellar. In the questionnaire survey,80% of cement cellars were applied, and the water storage period was generally 6 to 10 months. The sources of pollution around the cellar were wide and 43.3% of rural household poultry were free-ranged. Water cellar cleaning is not frequent-ly, 66.6% of residents did not wash water cellar. Water quality testing results showed that turbidity, pH and CODi value were out of limit,hidden over-standard hazards exist in bacteriological indicators. There are potential safety problems in rural cellar water in Gansu Province. Some indicators exceed the standard seriously, safety protection measure should be applied; economical and practical, simple and effective, scientific and reasonable water purification equipment and water purification method should be adopted to improve the safety quality of pit- water in rural areas.
