Abstract:

The coking wastewater of a coking plant has been studied by analyzing the effects of the influential factors， such as ultrasonic power，initial concentration，pH of the solution，reaction time etc. on the ultrasonic degradation of coking wastewater. The optimum technological conditions are determined by orthogonal tests. Under these conditions，the degradation efficiency of polycyclic aromatic hydrocarbon (PAH^s) of the coking wastewater is to be analyzed.

Key words: ultrasonic, coking wastewater, organic substances

摘要：
