摘要

摘要: 以某氯代烃污染场地地下水抽出方案为研究对象，利用数值模拟结合遗传算法展开优化研究，抽出处理的修复目标为在抽出360 d后地下水中ρ（CCl₄）<1500 μg/L，优化的目标函数为总抽出量最小。模拟优化结果显示：采用恒定抽出模式时初始备选井位于污染羽中轴线的方案优于均匀式的布井方案；将360 d分为2个阶段优化后的总抽出量相比于恒定抽出时减少了8.3%；阶段划分越多，优化后的总抽出量越少，抽出井个数越多；将360 d的抽出时间分为4个阶段优化后，总抽出量相比于2个阶段的抽出量减少了2.8%，但第4阶段单日抽出速率只有274 m³/d，在保持总抽出量不变的情况下，增大第4阶段抽出速率至814 m³/d，可以将抽出时间缩短至300 d。

Abstract: Taking the groundwater pumping scheme of a chlorinated hydrocarbon-contaminated site as an example, this paper used a numerical model combined algorithm and carried out optimization. The aim of pump-and-treat technology was that carbon tetrachloride concentration of the groundwater was less than 1500 μg/L after continuous extraction for 360 days. The optimization objective function was that the minimum total extraction volume. The simulation and optimization results showed that extraction volume of the initial wells, located in the central axis of the contaminated plume, was better than that of the uniform distribution. We divided the 360 days into two stages, and found that the total extraction volume reduced by 8.3% compared with the constant model. After dividing the 360-day extraction time into four stages, the optimized total extraction volume was reduced by 2.8% compared with the two stages model. However, the pumping rate of the fourth stage was only 274 m³/d. When keeping the total extraction amount stable, increasing the extraction rate of the fourth stage to 814 m³/d could shorten the extraction time to 300 days.
