摘要：In this paper, non-coal mine wastewater treatment based on RSM is studied. Experiments were conducted in a continuous SCWO system under different experimental conditions, as follows: pressure of 23 MPa; reaction temperature of 500°C- 650°C; reaction time of 0.5 - 1.5 h and oxidant concentration of 100 - 300 mg/L. The effects of reaction temperature, reaction time and oxidant concentration on COD removal were also investigated. Reaction temperature, reaction time and oxidant concentration are the important factors that affect COD removal. The optimum process parameters were 292 mg/L, 28.8 min, 406°C.
