摘　　要：近年来中国地下水污染越来越严重,国家对此高度重视。目前国内的地下水修复技术总体较为落后,物耗、能耗较高,且缺乏长效治理手段。土著微生物原位修复技术具有成本低、效果好、不易造成生态安全风险等优点,但是受限于技术水平,土著微生物法修复地下水在中国的工程应用中较少。综述了土著微生物修复地下水的总体工艺,介绍了土壤及地下水中土著微生物的性质及培养模式,对比选取注射井和直推式两种注入技术,以及国内外应用土著微生物修复地下水的工程实例,阐述了土著微生物修复技术在工程化应用中的瓶颈并提出展望。In recent years,the increasingly severe groundwater pollution in China has attracted the attention of the government.Currently,general groundwater remediation technology in China is relatively backward,with high material and energy consumption,as well as a lack of long-term treatment methods.Indigenous microbial in-situ remediation technology has advantages such as low cost,satisfactory efficacy,and low risk of ecological security,but has its scope and extend of application hampered in China due to the aforementioned technical limitations.Based on this,the research began with an review of the overall process of indigenous microbial groundwater remediation and introduced the properties as well as cultivation modes of indigenous microorganisms in soil and groundwater.Comparisons were then carried out to injection well and direct injection,as well as to the actual engineering cases reported in China and other parts of the world wherein indigenous microbial groundwater remediation was utilized.The bottlenecks arising therein were elaborated and future prospects were established.
