地下水作为重要的水资源，在农业、生活和工业等方面扮演着重要角色。尽管我国目前遏制了地下水污染持续加剧的状况，但地下水污染及后续修复问题仍需要高度重视，地下水修复涉及技术研究及装备应用两个方面，分别回顾了国内外的研究进展并对未来的研究进行了展望。首先对地下水异位及原位修复技术进行了概述。基于中国知网(CNKI)和Web of Science(WOS)数据库检索了近15年有关地下水原位和异位修复技术的应用研究，借助文献计量学软件CiteSpace进行深度分析。结果表明，WOS发文量自2011年起逐步提升，而CNKI发文量自2017年起开始有明显的上升趋势，这显示我国关于地下水修复技术的研究相比国外起步更晚。同时，关键词聚类和突现结果表明地下水修复技术研究经历了由低效率单一修复技术向多技术耦合进行高效绿色修复发展的过程。此外，综述了国内外主要修复装备的特点及应用情况，目前国外已有大量成熟的原位修复技术及相关装备应用案例，而我国的修复技术仍旧以异位修复为主，对于原位修复技术与装备的研发，相比国际先进水平还存在较大差距。最后，文章提出了针对当前挑战的多方面对策建议，如跨学科合作、加大研发投入等，以促进地下水修复技术和装备在国内的发展和应用。
R&D status and prospect of groundwater pollution remediation technology and equipment
Groundwater,as a crucial water resource,plays a significant role in agriculture,domestic life,and industry.Although China has currently mitigated the continuous worsening of groundwater pollution,the issues of groundwater contamination and subsequent remediation still require significant attention.Groundwater remediation involves both technical research and equipment application.This paper reviewed the progress of research in these areas domestically and internationally and provided an outlook on future research directions.First,an overview of ex-situ and in-situ groundwater remediation technologies was presented.Based on a bibliometric analysis using CiteSpace,derived from data retrieved from the China National Knowledge Infrastructure(CNKI)and Web of Science(WOS)databases over the past 15 years,the results indicated that the number of publications in WOS had gradually increased since 2011.In contrast,the number of publications in CNKI showed a significant rise only from 2017 onwards.This consequently demonstrated that China's research on groundwater remediation technologies commenced later than that in other countries.Furthermore,keyword clustering and burst detection results revealed that the research on groundwater remediation technologies had evolved from low-efficiency,single remediation methods to high-efficiency,green remediation through multi-technology coupling.Moreover,the characteristics and applications of major remediation equipment used domestically and internationally ware reviewed.Currently,numerous mature in-situ remediation technologies and associated equipment application cases existed abroad.However,China's remediation technologies predominantly relied on ex-situ methods,and there remained a considerable gap compared to international advanced levels in the development of in-situ remediation technologies and equipment.Finally,the paper proposed several countermeasures to address current challenges,such as promoting interdisciplinary collaboration and increasing investment in research and development.These measures aimed to advance the development and application of groundwater remediation technologies and equipment in China.
