Effects of Treatment Temperature and Time on Thermal Desorption of Hexachlorobenzene-Contaminated Soil

  • 摘要: 以山东潮土作为供试土壤,模拟HCB(六氯苯)污染土壤的热解吸试验研究. 考察处理温度和时间2个主要影响因素对热解吸后土壤中HCB的去除率及其热解产物变化的影响. 结果表明:随处理温度的升高和处理时间的延长,HCB的去除率逐渐增大,在处理温度400 ℃、处理时间10 min时,HCB的去除率达到94.2%;在处理温度450 ℃、处理时间60 min时,HCB 的去除率达到99.4 %,去除效果明显,w(HCB)达到HJ 350—2007《展览会用地土壤环境质量评价标准》的A级标准限值(≤0.66 mg/kg);继续升高处理温度和延长处理时间对HCB的去除率改变不大. HCB的热解吸过程不仅是HCB的物理分离过程,也存在HCB的还原脱氯过程,HCB的热解产物主要为1,3,5-TCB(1,3,5-三氯苯)和1,2,4-TCB(1,2,4-三氯苯);处理温度450 ℃、处理时间60 min为该污染土壤较为合适的热解吸运行参数.
