摘要
研究了超声波降解苯酚废水的效果和超声波对降解效果的影响因素,实验结果说明溶液初始浓度,温度,pH等因素对苯酚降解效果有明显影响.结果表明:溶液的初始浓度为135.15mg/L,超声辐射时间为4小时,温度为30℃,pH=3.0时,超声波降解苯酚的效果较好,为5.64%.曝气可以促进苯酚的降解,加入H2O2可使降解率提高到61.60%.
The degradation effect of phenol and influence of affecting factors such as initial concentration, reaction temperature, pH are studied in this paper. Results show that： under the conditions of aqueous solution 200mL, phenol initial concentration 135.15 mg/L, reaction temperature 30℃, initial pH value of 3.0, ultrasonic irritation for 4 hours, the degradation of phenol reaches 5.64%. In addition, aeration and H2O2 could accelerate the phenol removal rate, and the addition of Fenton reagent can raise the degrading-rate to 61.60%.
