Abstract: In the past thirty years,supercritical water oxidation (SCWO) has made great progress as a substitute for incineration in the treatment of highly concentrated industrial organic wastewater.As a new treatment technology,SCWO has however some defects such as corrosion and salt plugging problems to reactors,which hinder its application in the industrial waste treatment process.The existing problems of SCWO are described in details and the key points for industrial application of SCWO are explained and unscrambled.The future research direction of SCWO is proposed.In addition,the thermal energy utilization of SCWO is also described and the results show that SCWO has some great advantages than normal waste treatment technology.
