污染土壤热脱附技术的碳达峰碳中和路径初探

INVESTIGATION OF THE CARBONNEUTRALIZATION PATH WAY OF CARBONPEAKING BY TECHNOLOGY OF THERMAL REMEDIATION

热脱附修复技术具备修复效果好、修复速度快、适用范围广和二次污染可控等突出优点,广泛应用于各类有机污染土壤的修复,尤其对农药类和持久性有机污染物具有良好的适用性,具有很好的市场前景和应用推广价值。然而,热脱附技术能源需求量大,并且会破坏土壤性状,随着热脱附技术的广泛应用增加了土壤修复过程中的能源消耗从而间接增加了碳排放,另一方面由于土壤性状的破坏降低了土壤的固碳能力。为进一步分析热脱附技术应用的碳中和碳达峰路径,本文通过对国内外热脱附技术相关研究进行系统的回顾和分析,从优化修复技术、优化热脱附系统等方面讨论热脱附技术应用的碳减排路径,以期为热脱附技术的绿色可持续发展提供参考。

Thermal desorption remediation technology has the outstanding advantages of good remediation effect,fast remediation speed,wide application range,and controllable secondary pollution,which can be widely used in the remediation of various organic pollution plots,especially for pesticides,persistent organic pollutants,as well as has good market prospects and application promotion value.However,the application of thermal desorption technology requires a lot of energy and destroys the physical and chemical properties of the soil,which increases the energy consumption in the soil remediation process and indirectly increases the carbon emission with the wide application of thermal desorption technology.In order to further analyze the carbon neutral and carbon peaking pathways of thermal desorption technology application,this paper discusses the carbon reduction pathways of thermal desorption technology application in terms of fine investigation,optimization of remediation technology and optimization of thermal desorption system through a systematic review and analysis of thermal desorption technology related research at home and abroad,in order to provide reference for the green and sustainable development of thermal desorption technology.
