氯苯类化合物污染现状及其修复技术研究进展

Research progress on pollution status of chlorobenzene compounds and its remediation technology

氯苯类化合物(Chlorobenzenes,简称CBs)不仅是一种广泛使用的化工原料,还是一种持久性有机污染物,进入环境后难以分解,带来一系列潜在危害。鉴于CBs污染带来的严重性与技术修复的急迫性,综述了氯苯类化合物的使用状况及其在环境中的污染水平,论述了生物修复、物理化学修复、联合修复等对氯苯类污染物的修复技术研究进展;认为开发绿色环保、反应高效、价格低廉的单元技术或联合工艺是今后研究的重点,同时指出实现氯苯类污染物无害化处理是未来的发展方向。

Chlorobenzenes(CBs)are not only a widely used chemical raw material,but also a persistent organic pollutant,which is difficult to decompose after entering the environment and brings a series of potential hazards.In view of the seriousness of CBs pollution and the urgency of technical remediation,this paper reviewed the use of chlorobenzene compounds and their pollution levels in the environment through the combination of relevant literature and self-research,and discussed bioremediation,physical chemistry remediation,combined remediation and other remediation technologies for chlorobenzene pollutants;It was considered that the development of unit technology or combined process with green environmental protection,high reaction efficiency and low price was the focus of future research.At the same time,it was pointed out that the harmless treatment of chlorobenzene pollutants was the future development direction.
