摘要
渭河流域宝鸡段傍河集中地下水源地有 8个 ,主要开采由傍河地表水渗漏补给的承压含水层中的地下水 ,开采量约为 2 0× 1 0 4 m3/d,占宝鸡市总供水量的 77.2 %。依据实测资料和地质统计学分析 ,由于地下水的过量开采和渭河污染 ,导致潜水严重污染 ,承压水中个别水井受到有机污染。应减少地下水的开采量 ,并对城市污水处理 。
There are 8 groundwater well fields near the Weihe river in Baoji section along the Weihe river valley. Groundwater in confined aquifer recharged by infiltration of surface water near the rivers has been much explorated with yields of 20×10 4 m 3/d,accounting for 77.2% of total water supply in Baoji city. Based on the field measured data and geostatistical analysis,over exploration of groundwater and the pollution of the Weihe river have resulted in serious water pollution in phreatic aquifer. Some wells in the confined aquifer are subject to organic pollution. Accordingly, the volume of groundwater exploration should be reduced,and the city sewage treatment must be in agreement with water quality standard so as to let the sewage drain into the Weihe river.
