摘要
利用超声波/H2O2对甲基紫进行化学降解,然后用活性污泥进行生物降解.结果表明,超声波/H2O2对甲基紫的降解具有明显的协同作用,其降解率比超声波单独作用提高了40%,比H2O2单独作用提高了60%;降解率随超声功率、频率和超声时间的增大而增加;pH值对降解率的影响较大.经生物降解后,甲基紫总降解率可达96.3%,COD总降解率为93.5%.
Methyl violet solution was firstly degraded by ultrasonic and H2O2, and then degraded by activated sludge. The results showed that the synergistic effect of ultrasonic/H2O2 on the degradation of methyl violet was remarkable. It was 40% and 60% higher than the results by using ultrasonic and H2O2 alone. The degradation rate increased with ultrasonic power, sound density and the extension of ultrasonic time, and it was greatly influ- enced by the pH value of the solution. The total degradation rate of methyl violet and COD was 96.3% and 93. 5% respectively, after handled by activated sludge.
