摘要
持久性有机污染物(POPs)具有持久性生物累积性、半挥发性和长距离迁移的性质,广泛位于土壤、废水和污泥中。我国目前面临的POPs污染问题日益严峻。由于超临界水修复技术具有快速、高效、无毒等优点,在POPs修复方面具有较好的应用前景。从超临界水特性、国内外超临界水修复技术等方面系统分析了国内外超临界水修复的研究现状、超临界水修复技术的优缺点和适用性,提出了超临界水修复关键技术及装备系统,以期为其发展和提升提供参考。
Persistent organic pollutants(POPs)have the properties of persistent biological accumulation,semi-volatilization and long-distance migration,widely locate in soil,wastewater and sludge.POPs pollution in China is increasingly serious.Because of the advantages of supercritical water remediation technology,such as rapid,efficient and non-toxic,it has a good application prospect in the field of POPs remediation.Based on supercritical water characteristic and supercritical water remediation technology globally,the paper systematically analyzed the research status of supercritical water remediation and the merit/demerit and applicability of the technology.Then we put forward the key technology and equipment system of supercritical water remediation.The research results ccould provide reference for the development of supercritical water remediation technology.
