摘 要
城市地下水污染现状及修复技术研究聚焦于我国快速城市化进程中的地下水环境问题。随着工业化和城市化发展，地下水污染形势严峻，主要污染物包括重金属、有机物等，威胁着居民健康与生态安全。本研究旨在系统分析城市地下水污染特征，评估现有修复技术的有效性并提出优化方案。通过文献综述、现场采样监测以及实验室模拟实验相结合的方法，对典型城市区域地下水污染状况进行深入调查。结果表明，城市地下水污染具有复合性、隐蔽性和长期性的特点，传统单一修复技术难以满足治理需求。创新性地提出了基于多技术耦合的综合修复策略，集成物理、化学与生物修复手段，实现优势互补。研究表明，该耦合技术在处理复杂污染方面表现出显著优势，能够有效降低污染物浓度，提高修复效率。同时，构建了地下水污染风险评价体系，为科学制定污染防治政策提供依据。

Abstract
The research on the status of urban groundwater pollution and remediation technology focuses on the groundwater environment in the process of rapid urbanization in China. With the development of industrialization and urbanization, the situation of groundwater pollution is severe, and the main pollutants including heavy me tals, organic matter, etc., threaten the health and ecological security of residents. This study aims to systematically analyze the characteristics of urban groundwater pollution, evaluate the effectiveness of existing remediation techniques and propose optimization schemes. Through the combination of literature review, field sampling and monitoring and laboratory simulation experiment, the groundwater pollution in typical urban areas is thoroughly investigated. The results show that the urban groundwater pollution is complex, hidden and long-term, and the traditional single restoration technology is difficult to meet the treatment needs. It innovatively proposed a comprehensive repair strategy based on multi-technology coupling, integrating physical, chemical and biological repair means to realize complementary advantages. The study shows that the coupling technology shows significant advantages in handling complex pollution, and can effectively reduce the pollutant concentration and improve the repair efficiency. At the same time, the risk assessment system of groundwater pollution is constructed to provide a basis for the scientific formulation of pollution prevention and control policies.
