摘要
根据地形和水利工程现状，通过水动力学的分析和计算，将旧水库改建为给水系统的混凝沉淀设施。恰当选择水深和水面面积，合理确定供水口的位置高度，可使水中杂质的去除率达80％以上，使水质浊度达到滤前要求，提高净水厂的水质标准，而水库仍不失原有功能。使农田水利工程与农村给水工程相结合，是农业供水的一项新措施。
After water dynamics analysing and calculating,an old water reservior is rebuilt into a precipitating equipment combining with the terrain and the present condition of water project. Correct choicing of water depth and area, reasonable determining the elevation of water intake, the impurity removing rate can be increased to 80% to meet the requirements of muddy degree of water before filtering and impove the water quality standard of water purification plant,yet the water reservoir still keep its original functions. It is a new method of farming water supply,in which the irrigation and water conservancy engineering are combined with water service.
