摘要:

采用数值模拟技术对南水北调中线总干渠焦作段两侧地下水六价铬污染物的运移过程进行模拟,用情景分析对干渠两侧地下水水质的潜在影响进行预测,并对预测模型的4个主要参数进行灵敏性分析.结果表明,六价铬污染羽20年后可对总干渠水质安全构成一定的威胁.参数灵敏性分析表明渗透系数对六价铬的运移影响最敏感;分析结果还揭示了各个控制因素的主次关系及参数灵敏性随污染物不同迁移阶段的变化特征.该研究结果可为总干渠水质安全保障提供有力支持.

Abstract:

The hexavalent chromium transport in groundwater in Jiaozuo part of the middle route of south to north water transfer project was investigated by using the numerical simulation technology. The simulation results show that hexavalent chromium contamination plume may migrate to the area beneath the main canal about 20 years later, which will place a threat to the security of water quality of the main canal. Furthermore, the primary factors controlling the hexavalent chromium transport in groundwater were identified for different simulation periods. The investigation results may have implication on protection of water quality of the main canal.

Key words: middle route of south to north water transfer project, groundwater, hexavalent chromium, risk assessment of contamination, main controlling factors
