地下水超采区的治理与修复技术探讨
摘 要
地下水作为重要的淡水资源，对维持生态平衡和满足人类生产生活需求具有重要意义。然而，随着经济社会的发展，地下水超采问题日益严重，导致地下水位下降、水质恶化，甚至引发地面沉降等环境问题。因此，对地下水超采区的治理与修复技术进行深入探讨，具有重要的理论价值和实践意义。本文首先分析了地下水超采区的现状与影响，包括水位下降、水质恶化、生态系统退化等方面，揭示了超采问题对生态环境和人类社会的严重危害。接着，本文详细探讨了地下水超采区的治理策略，包括明确治理目标与原则、实施严格的地下水开采管控、加强水资源调度与管理、实施水源补给与生态修复等方面，旨在通过综合性的治理措施，有效遏制地下水超采的势头，本文系统介绍了抽提与回灌技术、生物修复技术、化学修复技术、物理修复技术以及联合修复技术等多种修复方法，并对各种技术的适用范围、操作要点和效果评估进行了详细阐述。这些修复技术针对不同类型的污染物和地下水条件，具有各自的优势和局限性，需要根据实际情况进行选择和应用，本文强调了地下水超采区治理与修复工作的紧迫性和长期性，提出了加强法规建设、推动科技创新、提高公众意识等建议，以期为地下水超采区的治理与修复提供科学指导和实践参考。通过本文的探讨，旨在促进地下水资源的合理利用和保护，实现经济社会与生态环境的协调发展。

Abstract
As an important fresh water resource, groundwater is of great significance to maintain the ecological balance and meet the needs of human production and life. However, with the development of economy and society, the problem of groundwater overexploitation is becoming increasingly serious, leading to the decline of groundwater level, the deterioration of water quality, and even causing environmental problems such as land subsidence. Therefore, it is of great theoretical value and practical significance to deeply explore the treatment and restoration technology of groundwater overmining area. This paper first analyzes the present situation and influence of groundwater overextraction area, including water level decline, water quality deterioration, ecosystem degradation, and reveals the serious harm of overextraction to the ecological environment and human society. Then, this paper discusses in detail the governance strategy of groundwater extraction area, including clear governance ob jectives and principles, the implementation of strict groundwater control, strengthen water resources scheduling and management, implementation of water supply and ecological restoration, aims to effectively curb the momentum of groundwater extraction through comprehensive measures, this paper system introduces the extraction and recharge technology, biological restoration technology, chemical repair technology, physical repair technology and joint repair methods, and the scope of application, operation points and effect evaluation. These repair technology for different types of pollutants and groundwater conditions, have their own advantages and limitations, need to choose according to the actual situation and application, this paper emphasizes the urgency and long-term, put forward to strengthen the construction of laws and regulations, promote scientific and technological innovation, raise public awareness, in order to provide scientific guidance for governance and repair of groundwater area and practical reference. Through the discussion of this paper, it aims to promote the rational utilization and protection of groundwater resources and realize the coordinated development of economic society and ecological environment.
