Experimental Study on the Treatment of HMX Explosive Wastewater by Fenton Process

Abstract

HMX has bactericidal properties. It is difficult to eliminate it by classic treatment methods. In this experiment Fenton reagent were employed to treat HMX wastewater. The effect of reaction time, H2O2 dosage, FeSO4•7H2O dosage, pH were investigated, and the optimum condition was determined via the single factor experiments. The results show that the treatment efficiency of HMX wastewater obviously by Fenton reagent. The optimum conditions with 25°C; H2O2 Concentration at 1% and dosage at 0.2mL; FeSO4•7H2O concentration at 0.01% and dosage at 8.3mL; pH at 3; reaction time at 80min;initial HMX concentration at 4mg/L and CODcr concentration at 214mg/L can reach the best removal efficiency of HMX as 81.4%and CODcr concentration at 155mg/L after the reaction.
