工业污泥超临界水氧化处理的研究进展

摘要

对各种工业污泥进行无害化处理与资源化利用是近年来国内外研究的重点.超临界水氧化是一种经济、高效的高级氧化技术,因其具有有机物氧化彻底、反应时间短等特点,用于工业污泥处理及资源化具有广阔前景.介绍了超临界水氧化技术在工业污泥处理中的研究情况,展望了未来的研究方向.%In recent years,the research focus in China is to treat various industrial sludge by nontoxic disposal and resource utilization. Supercritical Water Oxidation (SCWO),as a kind of economic and highly effective advanced oxidation technology,has broad application prospect in the treatment of industrial sludge and resource utilization, because it is characterized by complete organic oxidation and short reaction time ,etc. The research progress in the treatment of industrial sludge,aiming at the problems such as salt precipitation and corrosion,by SCWO is introduced, and its future research direction predicted.
