摘　　要：环境技术验证评价方法能够科学、客观地评价生态环境创新技术,促进新技术的推广应用。基于焦化污染地块修复技术验证评价方法,对原位热脱附-水平井-化学氧化耦合修复技术在山西某焦化污染地块上应用的可行性、绿色性、资源能源消耗等方面进行了验证评价。结果表明,该技术可以在一个修复周期内(3个月)将焦化污染地块中多环芳烃质量浓度降低到修复目标值,达到修复效果。修复系统运行过程中产生的废气、废水、噪声等污染物经处理后均满足相应排放要求。通过对修复过程中固废产生量、耗水量、耗电量、运行成本等指标的核算,可知该技术具有资源能源消耗较少、处理成本较低、针对不可开挖地块的修复具有较强适用性等特点。原位热脱附-水平井-化学氧化耦合修复技术可应用于焦化污染地块包气带污染土壤的修复治理工作。Environmental technology verification(ETV) can facilitate the promotion and application of new technologies through scientific and objective evaluation of innovative environmental technologies. Based on the verification and evaluation methods for coking-contaminated site remediation technologies, this paper verified and evaluated the feasibility, greenness, resource and energy consumption, and other dimensions of the coupled in-situ thermal conduction and desorption, horizontal well and chemical oxidation remediation technology when applied to a coking-contaminated site in Shanxi province. The results showed that the technology could achieve the desired remediation results by reducing the PAH concentrations at the contaminated site to the remediation target value within a remediation cycle(three months). The pollutants such as exhaust gas, wastewater and noise generated during the remediation process were emitted or discharged in accordance with relevant requirements.According to the calculations of the amount of solid waste, water and electricity consumption, operating costs,etc. incurred in the remediation process, the technology features low resource and energy consumption, low treatment costs and strong applicability to the remediation of sites that cannot be excavated. This verification and evaluation case study suggested that the coupled in-situ thermal conduction and desorption, horizontal well and chemical oxidation remediation technology could be applied to the remediation of aeration zone contaminated soil at coking-contaminated sites.
