摘要
针对疏水性有机污染土壤,根据修复技术原理分类介绍了目前国内外常见的几种异位物理化学修复技术的研究进展,具体包括以污染转移为基础的土壤热脱附与化学淋洗技术和以污染降解为基础的化学氧化与化学还原技术两大类;并指出修复技术的选择或组合需结合特定污染地块的实际情况及修复技术的有效性、经济性、安全性和可操作性等多方面因素。
For the remediation of hydrophobic organic chemicals(HOCs) contaminated soil, research development of various ex-situ physical/chemical remediation technologies is presented in details based on two major principles including contamination transfer and contamination degradation. Thermal desorption and soil washing are introduced based on contamination transfer, while chemical oxidation and chemical reduction technologies are introduced on basis of contamination degradation. The selection of remediation technology or combination of different technologies should synthesize the contamination details of the specific contaminated sites and the effectiveness, economy, safety and feasibility of the remediation technology.
