国内某污染地块开展异位热脱附技术试验,结果表明,热脱附技术对土壤中的苯并[a]蒽、苯并[a]芘、苯并[b]荧蒽、二苯并[a,h]蒽和茚并[1,2,3-cd]芘具有良好的去除效果,平均去除率分别为99.4%、97.6%、99.3%、91.5%、99.1%.加热温度和停留时间是影响热脱附效果的两大主要因素,将加热温度和停留时间进行正交试验,以探明最合适的热脱附工艺参数,从而为热脱附技术在污染土壤实际修复工程中的应用设计提供参考.
Applied Research of Ex-Situ Thermal Desorption Technology in Remediation of SVOCs Contaminated Site
The Ex-Situ Thermal Desorption technology was tested in a contaminated site in China.The results demonstrated that the thermal desorption technology had excellent removal efficacy for Benzo(a)anthracene,Benzo(a)pyrene,Benzo(b)fluoranthene,Dibenzo(a,h)anthracene and Indeno(1,2,3-cd)pyrene in soil,with average removal rates of 99.4%,97.6%,99.3%,91.5%and 99.1%respectively.Heating temperature and residence time are the two primary factors influencing the efficiency of thermal desorption.Conducting an orthogonal experiment on both heating temperature and residence time to identify the most suitable thermal desorption process parameters,in order to provide a reference for the application design of thermal desorption technology in actual remediation projects.
