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，本文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。该过滤器是可防冻和投资少外，还靠地形落差自动清洗、蓄水功能的过滤饮水水源装置。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。

The development of industry and the emission of sewage cause the pollution of underground,groundwater pollution and the people＇s interests are closely related to scientific problems. Currently the drinking water project solves the problem of drinking water in some areas.To solve this problem,this paper adopts the bucket into water,water storage capacity and establishes a balance relationship between the water drop location and terrain catchments. Outside the filter is antifreeze and less investment. By engineering practice,an example is given to illustrate the catchments type filter press since the gills,and a method for determining the size of the for plain provides a reference for the design of urban and rural drinking water safety project.
