西北地区部队营区自备水水源污染状况

目的了解西北地区(陕、甘、宁、青4省区)部队营区自备生活饮用水水源卫生状况.方法对西北地区部队营区194个自备水源进行现场采样并检测大肠菌群、氨氮、亚硝酸盐氮.检测方法均依照GJB 1096-91<军队战时饮用水标准检验法>,采用我军在战区水源卫生调查时试用的三级分类评价方法进行评价.结果194个水源水大肠菌群合格率较低,仅为48.0%,氨氮合格率为55.2%,亚硝酸盐氮合格率为90.2%.对水质污染程度进行综合评价,未受污染的水源只占30.4%(59/194),有66.0%(128/194)的水源受到轻度污染,还有3.6%(7/194)水源受到严重污染.结论西北地区部队营区69.6%的自备生活饮用水水源受到不同程度的污染,应采取有效消毒措施.同时,加强饮水卫生监测监督,完善水源管理制度,减少水源污染.
