The effect of spread of the plant leachate on downstream pumping wells is studied, and.a factory model of groundwater flow and solute transport model are set up. Results show that the regional groundwater flows from north to south, and along the flow direction the water level decreases relatively moderately. Groundwater descent funnel is formed in the downstream pumping well. Pollutant concentration continues to increase, with local pollutant concentration as high as 4.1mg/L, which has gradually exceeded the scope of pollution. The pollution area is about 823509.67m2 and the downstream diffusion length is about 1084.64m. In the vertical direction, plant pollutants have spread to the second-level deep aquifer. If not controlled, the water output will intensify the pollutant diffusion velocity., authors=SUN Lifeng1 , WANG Chuang2 , authorsList=SUN Lifeng, WANG Chuang, authorCompany=1.

GMS是目前地下水数值计算的重要应用软件之一,运用GMS可以模拟地下水流分布和地下水污染物的迁移规律等。以化工厂区为例,经过地质模型概化、参数确定、调参等过程,预测污染物的浓度及污染范围。研究了该厂区渗滤液的扩散对下游抽水井的影响,建立了该厂区地下水流模型及溶质运移模型。结果表明,该区域地下水流向为自北向南,沿水流方向水位逐渐下降,水降幅度较为缓和,在下游抽水井附近形成地下水降落漏斗;污染物的浓度在持续增加,局部污染物浓度高达4.1mg/L,污染的范围也逐渐扩大,污染面积约为8.23×105 m2 ,污染物向下游扩散长度约1084.64 m,在垂向上,厂区位置污染物已经扩散到第二层深水含水层。若不加以控制抽水量,会加剧污染物的扩散速度。

GMS is the important groundwater numerical software to simulate groundwater flow distribution, migration of groundwater contaminants, etc. This paper takes the chemical plant zone as an example and uses GMS to predict the concentration of pollutants and the polluted area after generalizing the geological model, parameter identification, and adjusting-parameter processes. The effect of spread of the plant leachate on downstream pumping wells is studied, and.a factory model of groundwater flow and solute transport model are set up. Results show that the regional groundwater flows from north to south, and along the flow direction the water level decreases relatively moderately. Groundwater descent funnel is formed in the downstream pumping well. Pollutant concentration continues to increase, with local pollutant concentration as high as 4.1mg/L, which has gradually exceeded the scope of pollution. The pollution area is about 823509.67m2 and the downstream diffusion length is about 1084.64m. In the vertical direction, plant pollutants have spread to the second-level deep aquifer. If not controlled, the water output will intensify the pollutant diffusion velocity.
