Coupled Methods for Effective Degradation of Harmful Chlorobenzene

With the high speed development of the chemical, pharmaceutical and pesticides industry, more and more chloro-organic wastewater will be discharged into the environment. The wastewater will cause great damages to the environment and public health because the halogenated organic matter has characters of biology toxicity, persistence, and environment build-up effect. Aerated biological packing tower and sono-reactors are both valid equipment for treating chlorobenzene (CB). This paper compares the effects of these two equipments when used in the treatment of CB, mainly in respect of initial CB concentration, reaction time, aeration intensity, and ultrasonic frequency. Besides, it pays close attention to the resultant effects of degradation of CB by coupling of reverberation ultrasonic reactor with aerated biological packing tower.
