摘要
目前,国内外主流的地下水污染风险管控技术有9种,即水动力控制技术、地下阻滞拦截技术、抽取-处理技术、两相抽提技术、原位冲洗技术、原位空气扰动技术、地下可渗透反应屏障技术、原位化学氧化还原技术和原位微生物技术。本文结合裂隙介质中地下水特征,分析国内外主流的地下水污染风险管控技术,并采用评分法对其进行筛选。研究表明,地下阻滞拦截技术是裂隙介质中地下水污染风险管控的最有效手段,其次为水动力控制技术、抽取-处理技术。
At present,there are nine mainstream risk management and control technologies of groundwater pollution at home and abroad,namely hydrodynamic control technology,underground blocking and interception technology,extraction-treatment technology,two-phase extraction technology,in-situ flushing technology,in-situ air disturbance technology,underground permeable reaction barrier technology,in-situ chemical redox technology and in-situ microbial technology.Combined with the characteristics of groundwater in fractured media,this paper analyzes the mainstream risk management and control technologies of groundwater pollution at home and abroad,and uses the scoring method to screen them.The research shows that the underground blocking and interception technology is the most effective means for risk management and control of groundwater pollution in fractured media,followed by hydrodynamic control technology and extraction-treatment technology.
