Kinetics for Sulfate Removal in Tannery Wastewater by Immobilized Activated Sludge

Abstract:

Article Preview

The anaerobic activated sludge inoculated with an isolated SRB was immobilized on the granular activated carbon and the kinetics for the immobilized anaerobic sludge treating the sulfate in tannery wastewater was studied. Also, the aerobic activated sludge containing enriched SOB was immobilized and the kinetics for the sulfur conversion was studied with the immobilized aerobic sludge through treating sulfide (the reduction product of SO42-) in tannery wastewater. The results showed that the kinetics for treating SO4 2- with the immobilized SRB in the actual tannery wastewater could be expressed as follows: lnC =-0.04941 t+6.79764. The kinetics for the sulfur conversion with the immobilized SOB through treating the sulfide in the actual tannery wastewater could be expressed as follows: lnC =0.01109 t+3.09996. The established dynamic equations could predict the capacity of sulfate removal and sulfur conversion in tannery wastewater.
