Research and Application Progress of In-Situ Chemical Oxidation Technology Combined with Controlled Release Materials for Continuous Remediation of Organic Contaminated Groundwater
The problems such as anti diffusion,tailing,and rebound of organic pollutants seriously affect the remediation effect of traditional In-Situ Chemical Oxidation(ISCO)technology on polluted groundwater.The controlled release technology can achieve long-term and continuous remediation of polluted groundwater,which is an effective way to ensure the effectiveness of in-situ chemical oxidation remediation.After extensive literature research,the principle of Controlled Release Materials-In-Situ Chemical Oxidation(CRM-ISCO)technology and the material composition of controlled release materials are introduced,and the research status and engineering application progress of CRM-ISCO technology are systematically analyzed for groundwater remediation at home and abroad,and the existing problems are summarized in technology application,and the prospects are provided,in order to provide reference for the promotion and application of CRM-ISCO technology in the remediation of organic contaminated groundwater in China.
