超临界水氧化技术

Supercritical water oxidation technology

超临界水氧化(SCWO)技术是一种新兴的、很有前景的处理有机污染物的环保技术,具有很多特色和优势。然而,SCWO主要问题是反应器的腐蚀和盐的沉积,阻碍了SCWO的推广和工业应用。阐明了不同的反应器和工艺的改进观念,论述了SCWO存在的问题,讨论了可能的解决措施,并对SCWO系统中未来的发展提出了建议。

Supercritical water oxidation(SCWO) is a new and promising environmental protection technique which can totally and efficiently be used to treat organic pollutions. It has some characteristics and superiority. However, SCWO as an endofpipe technology has some disadvantages that have hindered its popularization and application. The key problems are reactor corrosion and salt precipitation. The main existing problems of SCWO are described and the possible solutions are discussed, different reactor and process concepts are elucidated, and a suggestion for future research and technical procedure in the SCWO field is given.
