| 摘 要： | 通过对甘肃省“121”雨水集流工程以人畜饮用为主要用途的6个代表样点水泥窖储水的理化指标和生物学指标的测试分析,表明水泥窖储水的水质大部分达不到国家生活饮用水的卫生标准,属中污性水体。提出厂预防污染,改良水泥窖储水水质的主要技术是：净化集流环境→弃去初集水→砂层过滤沉淀→多窖集流、轮流使用→化学消毒→净水器过滤→延长煮沸时间→合格饮用水。

| Abstract: | Based on physical, chemical and biological analysis of 6 samples from typical water cellars for livelihood and animals of the "121" Rain Collection Project in Gansu Province, it is shown that the water quality of the cellars is below the National Health Standard of Drinking Water. It is middle polluted drinking water. And then the author put forwards a technical way to prevent the pollution and improve the water quality of the cellars,the step as follows: improving the rain catchment environment; putting away initial collected water; filtrating and settling by sand layers; collecting the rain by multi cellars and fetching the water by turns; disinfecting the water through chemical methods filtrating by clarification; prolonging the boiling time; finally getting qualified drinking water. |
