摘　　要：基于抽出–处理的污染地下水修复是一种有效的修复技术,具有简单易行、可控性强、适用范围广等优点。该方法可以为决策者提供更直观的修复效果,提高污染地下水修复的效率。同时,该方法可以为工程实践提供技术支持和决策依据,提高修复效率和成本效益。本研究采用数值模拟方法对污染地下水进行抽出处理,通过模拟地下水流动和污染物运移过程,预测了污染范围和程度。接下来建立修复方案优化模型,考虑了不同目标函数对修复效果的影响,并采用粒子群方法进行方案的优化。计算结果表明,粒子群算法与地下水流模拟程序(MODFLOW)和污染物运移程序(MT3DMS)的耦合可以实现合理的抽出处理方案,并设计出符合管理目标的修复系统,为地下水污染现场的修复提供科学的工程指导。Pump and treat method of contaminated groundwater remediation is an effective remediation technique, which has the advantages of simplicity, controllability, and wide applicability. This method can provide decision-makers with a more intuitive remediation effect and improve the efficiency of contaminated groundwater remediation. This method can also provide technical support and decision basis for engineering practice and improve remediation efficiency and cost effectiveness. In this study, numerical simulation was used to simulate the pump and treat of the contaminated groundwater. By simulating the process of groundwater flow and pollutant migra-tion, the distribution and degree of pollution plume were predicted by simulating the groundwa-ter flow and contaminant transport processes. On the basis of the simulation model, a remediation scheme optimization model was established, considering the effects of different objective functions on the remediation effect, and the particle swarm optimization approach was used for the optimization of the scheme. The results show that the coupling of the particle swarm optimization with the groundwater flow simulation program (MODFLOW) and the contaminant transport program (MT3DMS) can achieve a reasonable pump and treat scheme and design a remediation system that meets the management objectives, providing scientific engineering guidance for the remediation of groundwater contamination sites.
