超声波预处理含酚废水技术研究

Research on treatment of phenol-containing wastewater by ultrasound technology

利用超声波预处理含酚废水,研究了超声波功率、超声波反应时间、废水pH的影响。结果表明,超声功率500 W,振荡时间40 min,废水pH 5.9时,对含酚废水的预处理效果最佳,COD去除率可达48.53%。此方法具有投资成本低、操作简单、处理效果好、无二次污染等优点,具有广阔的应用前景。

Ultrasound process has been used for the treatment of phenol-containing wastewater. The influence of ultrasonic power,reaction time and wastewater pH was investigated. The results showed that： ultrasonic power 500 W,reaction time 40 min,pH 5. 9. The highest COD removing rate reaches 48. 53%. This method show that the running cast is low,the operation is simple and convenient,the treatment efficiency of this process is good and has broad application prospects.
