超声助Fenton试剂处理HMX炸药废水

Treatment of HMX Wastewater with US/Fenton Technology

为降解HMX生产过程中的废水,使用US(超声波)/Fenton试剂在常温下对HMX废水进行了处理。结果表明,在超声波频率为60kHz条件下,Fenton试剂对HMX废水的处理效果很好,在HMX初始浓度为200mg/L、pH值为2、双氧水(质量分数为10%)用量为1mL、FeSO4溶液(质量分数10%)用量0.5mL、反应时间为80min条件下HMX去除率达90%,COD去除率达51%。

In order to degrade toxic wastewater from producing HMX, US/Fenton reagent was employed to treat HMX wastewater at room temperature. The results show that US/Fenton reagent performs well in treatment of HMX wastewater when the frequency of ultrasonic is 60kHz. Under the conditions of initial HMX concentration of 200mg/L, pH=2, H2O2（mass fraction 10%）dosage of 1mL, FeSO4 · 7H2O （mass fraction 10%）dosage of 0.5mL, reaction time of 80min, the best removal efficiency of HMX and COD are 90% and 51% ,respectively.
