超声波在活性炭深度处理污水中的作用

STUDY ON EFFECTS OF ULTRASONIC AND ACTIVATED CARBON TO WASTE WATER

为解决超声波与活性炭联合处理石油污水的COD问题,利用超声波与活性炭对溶液的作用机理,分别对超声波在活性炭处理前、处理中及处理后所起的作用进行了实验研究。结果表明,在活性炭进行处理之前先用超声波进行处理,COD的降低率最高。说明用超声波作为预处理手段,有助于提高后续活性炭处理的效果。

The principle in which ultrasonic and activated carbon act on solution is first elaborated.Then ultrasonic and activated carbon are used to treat waste water together,and three different ways are experimentally studied.It is found that if ultrasonic is used to treat waste water first,the degradation of COD is the highest. 
