Abstract

The pretreatment of coking wastewater with a mixed reactor containing carbon steel scrap and active carbon has been studied. The mechanism of COD removal in coking wastewater was also studied based on the electrochemical principles of corrosion. It was found that the mixed reactor effectively removed COD in coking wastewater, with the COD removal reaching as high as 80%. There were no significant effects on the COD removal when varying the pH value with reaction times of approximately two hours, and the COD removal was increased by ~5% by addition of a flocculent to the coking wastewater. The COD removal of coking wastewater with the mixed reactor containing carbon steel scrap and active carbon was achieved mainly through electro-coagulation.
