The supercritical water oxidation device and the supercritical technology was used to treat solid propellant production wastewater. The relationship among oxygen flow,waste water flow,temperature,pressure of reactor and the removal efficiency of NH3 N in ammonium perchlorate wastewater was investigated. The results show that the optimal conditions of the supercritical water oxidation are as follows:temperature is 390~410℃,pressure is 22 MPa,oxygen flow is 0. 6~1. 0 L/min and wastewater flow is 2 L/h. Under such condition,removal efficiency of NH3 N can reach 99%,NH3 N concentration of treated waste water is less than 3 mg/L, which meet national standards.
