地下水循环井(groundwater circulation well,GCW)是一种集可耦合抽提、生物强化和化学氧化还原于一体的原位修复技术,然而运行过程中井体堵塞严重影响其使用寿命、运行费用、修复效能.本文通过回顾国内外各类地下井体堵塞研究进展,结合GCW结构特点及场地水文地质条件,系统地梳理了堵塞成因.针对物理堵塞、化学堵塞和生物堵塞形成机理,总结了 GCW堵塞数学预测模型及场地识别技术,同时系统综述了现有破阻技术及适用范围.最后针对GCW建井初期防堵设计-运行期间堵塞预测识别-堵塞发生后的破阻技术方法3个方面,提出了未来研究及场地应用发展方向展望,以期为GCW优化设计、场地维护及解堵措施提供理论支撑及技术参考.
Review of the clogging causes idenfication and anti-clogging techniques for groundwater circulation well
Groundwater circulation well(GCW)is an in-situ remediation technology that integrates coupled extraction,bioaugmentation and chemical oxidation and reduction.However,the blockage of the well significantly impacts its lifespan,operational expenses,and restoration effectiveness.Based on the structural features of GCW and the hydrogeological circumstances of contaminated site,this paper comprehensively reviewed the research progress on blockage of various underground well.The existing prediction methodologies and detection technologies for GCW blockage,including physical,chemical and biological blockage were summarized.The blockage breaking technologies and their applicable scope were systematically provided.Finally,this paper proposed the future research and application development direction from the aspects of 1)anti-blockage design for GCW structure optimization,2)blokage prediction and identification techniques during GCW operation,3)GCW blockage breaking and maintenance technology.
