Supercritical water oxidation (SCWO) is a new oxidation technology that utilizes supercritical water reaction to destroy the configuration of matter. Organic waste is converted to harmless gaseous or liquid substances such as CO2 and H2O. Thanks to its unique technology advantage, it has a rapid development in the recent years, and becoming a potential and green technology of wastewater and organic waste treatment. This paper focused on SCWO technology and apparatus, and reviewed achievements on patents of wastewater and organic waste treatment by SCWO. Eventually, this article prospected the development trend of this new oxidation technology.

Keywords: Wastewater, organic waste, oxidation technology, supercritical water
