摘要：In this paper, supercritical water oxidation (SCWO) is adopted to treat the petroleum wastewater. Box-Behnken design (BBD), an experimental design for response surface methodology (RSM), was used to create a set of 27 experimental runs needed for optimizing of the operating conditions. Temperature, reaction pressure, residence time and oxidant dosage are examined factors. The experimental results show that SCWO could effectively reduce TOC removal by 96.33%. SCWO process is possibly suitable for a primary treatment for petroleum wastewater. Response surface methodology (RSM) could be effectively adopted to optimize the operating multifactors.
