摘要 为了处理黑索今(RDX)废水,研究了十六烷基三甲基溴化铵(CTMAB)改性膨润土的用量、pH值、振荡频率、振荡时间、活化温度对CTMAB改性膨润土处理RDX废水效果的影响。CTMAB改性膨润土对RDX废水有较好的处理效果,在振荡频率为100 r/min下,RDX废水初始浓度120 mg/L、CTMAB改性膨润土的用量为1.2 g、pH为7、活化温度60℃、振荡时间80 min时,RDX去除率达到94.8%,CODCr去除率为82.5%。 In this paper, the bentonite modified by CTMAB was employed to dispose RDX wastewater. The efficiency was affected by factors such as the dosage of bentonite modified by CTMAB, the pH value, the oscillation frequency, the oscillation time and the activation temperature. The test results showed that the bentonite modified by CTMAB could effectively dispose the RDX wastewater. Under the condition of that the oscillation frequency was 120 r/min, the concentration of RDX was 120 mg/L, the dosage of bentonite modified by CTMAB was 1.2 g, the pH value was 7, the activation temperature was 60 ℃ and the oscillation time was 80 min. The removal efficiency of RDX reached 94.8% and the removal efficiency of CODCr come up to 82.5%.
