淮河流域(河南段)地下水质量状况及污染原因研究

Study on the Status of Groundwater Quality and the Pollution Causes in Huaihe River Basin

通过环境地质调查和水样测试分析 ,在淮河流域的周口 -项城 -沈丘一带 ,地下水质量具有垂向分带性 ,其原因主要有城市"三废"的排放、地表水的污染、污灌回渗和农药化肥的不合理使用等 ,所造成的地下水污染结果 ;并在平面上呈现点状、带状或面状污染地下水分布。

Through the environmental geological survey and the tests of water samples in Zhoukou Xiangcheng Shenqiu area along the Huaihe river basin, it is shown that the quality of the groundwater is with the characteristic of vertical zonality. The pollution of the groundwater is mainly caused by the discharge of the urban solid, liquid and gas wastes, the sewage infiltration of the polluted surface water, the unreasonable uses of insecticides and fertilizers. The pollution distributes with the point form, zone form and the area form.
