污染场地热脱附修复技术的文献统计分析

Literature Statistics on Thermal Desorption Technology of Contaminated Sites

为了研究国内污染场地热修复技术的发展趋势,从文献、专利统计的角度,分析总结了相关的文献出版趋势、文献类型及其比例、原位/异位热脱附技术的专利公开等情况。结果表明,夯实基础(2008—2015年)、快速发展(2016—2020年)、广泛应用(2020—2021年)分别是国内热脱附技术发展的3个阶段,与国家法律法规、技术导则的发布实施、国内土壤热修复技术产业市场的发展趋势基本一致;关于热脱附技术应用的相关文献类型较多(高达89.4%),推动了国内热脱附修复技术的推广应用和污染场地修复实践;2019年以来,原位热脱附的文献出版和专利公开比例均明显高于异位热脱附,因为前者更符合绿色可持续修复理念和国家“双碳”战略。

In order to clarify the development trend of domestic thermal remediation technology for contaminated sites,the relevant trends,types and proportions of published literatures,and patent disclosures of In-situ/Ex-situ thermal desorption technologies are analyzed and summarized from the perspective of literature and patent statistics.The conclusions are as follows:laying the foundation(2008-2015),rapid development(2016-2020)and widespread applicaiton(2020-2021)are the three stages of domestic thermal desorption technology.This is basically consistent with the publication and implementation of national laws and regulations,technical guidelines,and the developing trend of the domestic market of soil thermal remediation.There are more literatures related with thermal desorption technology applications(up to 89.4%),which greatly promoted the domestic application of thermal desorption technology and the practice of contaminated site remediation.Since 2019,the ratio of published literatures and disclosed patents for in situ thermal desorption is significantly higher than those for ex situ thermal desorption,because the former is more in line with the concept of green sustainable remediation and the national“double carbon”strategy.
