随着工农业的发展排放大量超标污水,导致地下污染,地下水的污染与广大人民利益密有切相关的科学问题。目前采用饮水工程的水源向河道上游移的方法解决了部分地区的饮水问题,山区不仅地形复杂、坡度大、修建清水池难,而且工程的投入多。为解决此问题,采用集水桶的进水量、蓄水量及用水量间建立平衡关系,此平衡关系与水源位置和地形落差相结合研制了集水式自压鱼鳃过滤器。该过滤器除可防冻和投资少外,并可利用地形落差达到自动清洗、蓄水功能。采用工程实例说明集水式自压鱼鳃过滤器尺寸的确定方法,为平原城市及农村饮水安全工程的设计提供依据。
With the development of industry and agriculture discharge a large number of excessive sewage, leading to underground pollution, groundwater pollution and the interests of the broad masses of people closely related to the scientific issues. At present, the method of using the water source of drinking water project to move upstream of the river channel solves the problem of drinking water in some areas. The mountainous area not only has complex terrain, large slope, difficult to construct clean water pool, and more investment in the project. In order to solve this problem, the balance between water intake, water storage and water consumption of the water collecting bucket is established. The water balance and the position of the water source and the fall of the terrain are combined to develop a water collecting self-pressured fish-gill filter. In addition to the filter can be frost-free and less investment, and the use of terrain drop to achieve automatic cleaning, water storage function. The engineering example is used to illustrate the method of determining the size of the water-filled self-pressured fish gill filter, which provides the basis for the design of drinking water safety project in the plain and rural areas.
