摘　　要：数值模拟技术是保护地下水环境的有效方法,但实际中获取准确的水文地质参数难度较大,如何准确获取参数成为数值模拟技术应用成败的关键。基于该关键问题,本文以广西某钛白粉厂为例,在查明水文地质特征基础上,应用Visual MODFLOW软件建立地下水流数学模型和溶质运移模型。选取钛白粉厂主要污染物COD、氨氮和氟化物作为预测因子,预测其在地下水中运移情况。结果反映钛白粉厂污水处理车间和污水调节池发生渗漏未对下游地谷岭造成影响。本次模拟的预测结果对该区地下水的保护有着重要意义。Numerical simulation technology is an effective method to protect the groundwater environment,but it is difficult to obtain accurate hydrogeological parameters in practice,and how to obtain the parameters accurately becomes the key to the success or failure of the application of numerical simulation technology.Based on this key issue,this paper takes a titanium dioxide plant in Guangxi as an example,and establishes a mathematical model of groundwater flow and a solute transport model by applying Visual MODFLOW software on the basis of identifying hydrogeological characteristics.The main pollutants COD,ammonia nitrogen and fluoride of the titanium dioxide factory were selected as predictors to predict their transportation in groundwater.The results reflect that leakage from the wastewater treatment plant and the wastewater conditioning tank of the titanium dioxide plant did not affect the downstream valley ridge.The predicted results of this simulation are of great significance for the protection of groundwater in this area.
