挥发性有机污染土壤异位低温热脱附中试研究

Pilot Study of Ex-situ Low Temperature Thermal Desorption of Volatile Organic Contaminated Soils

本文主要对某退役农药厂场地中挥发性有机污染土壤成分进行分析,针对其中挥发性有机污染物易挥发及难氧化的特点,采用异位低温热脱附工艺以及土壤修复机进行中试试验,分析试验中不同投加比的发热剂对于某退役农药厂场地中挥发性有机污染土壤修复效果及经济评价。

This paper mainly analyzes the composition of VOC contaminated soil in a site of a retired pesticide plant, aiming at the characteristics of which VOCs are volatile and difficult to oxidize, an ectopic low-temperature thermal desorption process is used as well as soil remediation machines in pilot tests, and analyses of the effects of different dosages of heating agents on the remediation of VOC contaminated soil in a site of a retired pesticide plant And economic evaluation.
