摘要
考察了在不同空化状态下超声波对石油污水化学耗氧量 (COD)的降低作用。探讨了时间、功率、pH值及温度对石油污水化学耗氧量降低作用的影响。结果表明 ,石油污水化学耗氧量的降低率随着时间增大而增大 ,随着温度、pH值的增加而减小 ,随着功率的增加 ,先增加 ,然后再减小。
This experimental study was about the degradation of chemical oxygen demand (COD) in petroleum waste water treated with ultrasonic under different cavitating conditions,and the effects associated with time,power,pH and temperature were discussed.It was found that the degradation rate of COD increased with the increase of reaction time,while decreased with the increase of temperature and pH.With the increase of the ultrasonic wave power,the degradation rate of COD went first up and then down.
