摘要
对毒性较强的苯酚化合物进行超声降解,研究溶液pH值、超声功率、反应时间等对降解率的影响。并通过试验,对H2O2单一处理效果和超声强化H2O4降解效果进行了比较。结果表明,在处理液pH值为1,温度为30℃,超声处理功率为180 W,H2O2投入浓度为300 mg/L时,超声波和H2O2联合作用90 min,对苯酚的降解率可达到83.8%。
The paper studied the effect of pH value,ultrasonic power and reaction time on the ultrasonic degradation of phenolic compounds which had very strong toxicity.Through the experiment,the degradation effects of hydrogen peroxide and ultrasonic enhanced hydrogen peroxide were compared.The results indicated that,under 1 of pH value,30 ℃ temperature,180 W of ultrasonic power,300 mg/L of H2O2,as well as the combined treatment of ultrasound and H2O2 for 90 min,the degradation rate of phenol could reach 83.8%.
