【摘要】 利用水质检测数据,开展凉水河截污清淤前后河道两侧浅层地下水水环境对比,研究表明:清淤后,浅层地下水污染程度加重,地下水的总硬度和溶解性总固体(TDS)显著升高。因此,在河道满足行洪能力、河水水质尚未大幅度改善的情况下,应慎重清淤。更多还原

【Abstract】 The paper analyzed the groundwater quality change before and after dredging using water quality test data.The result showed the shallow groundwater quality is more serious and the concentration of total hardness and TDS are higher after dredging.It concluded dredging should be evaluated before its implementation when the river meets the requirement of flood control and the water quality has not been improved significantly.更多还原
