Design of Impinging Stream-Cavitations and Micro-Electrolysis Reactor and Treatment of High Concentration Wastewater

Abstract:

A micro-electrolysis reactor combined with the technology of impinging stream-cavitations drum was designed. Then it was used in the treatment of high concentration wastewater. Under the conditions of reaction time is 60 min, ratio of iron to carbon is 1 and the pressure of the air compressor is 8Mpa, the COD and chromaticity could remove 95.7% and 85.9% respectively. The biodegradability was improved obviously with 0.55 of BOD5/COD. The determinations of kinetics under the best conditions show that, the mode of COD removal basically conforms to the rule of first order kinetics. The reaction rate in our reactor was faster than only micro-electrolysis or only cavitations obviously. The conjunction of impinging stream-cavitations and micro-electrolysis has good synergism and facilitation.
