摘　　要：综述二口恶英的来源、成因和危害 ,讨论前人在治理二口恶英方面所采用的热技术和非热技术及其存在的局限性。二口恶英治理的热技术包括高温过燃烧技术、红外脱毒技术、等离子体高温分解技术、熔盐脱毒技术、超临界水氧化技术、原位玻璃化技术等 ;非热技术包括化学脱氯技术、紫外光解技术、溶剂萃取技术、吸附技术、生物降解技术、化学降解技术、γ射线分解技术、光催化氧化技术等。Sources and toxicity of dioxins were reviewed. The thermal technologies and non-thermal technologies used for treating dioxins were discussed with focus on their limitations. The thermal technologies included high temperature over-burning, infrared destruction, plasma arc pyrolysis, molten salt destruction, supercritical water oxidation, in situ vitrification, and etc.The non-thermal technologies included chemical dechlorination, ultraviolet photolysis, solvent extraction,adsorption,biodegradation, chemical degradation, x-ray photolysis, photocatalysis oxidation,and etc.The main difficulties encountered in the process of treatment were also analyzed briefly.
