Description

Denitrification and sulfate reduction of phenolic wastewater were examined using anaerobicoxic biological filter reactor. In the anaerobic reactor, sulfate reduction occurred. However phenol was not removed. In the anoxic reactor, heterotrophic denitrification and sulfur denitrification were occurred simultaneously. Phenol was utilized for denitrification. Utilization of cokes gas liquor wastewater by sulfate reduction and denitrificatin was examined using the biofilm in the reactor. Sulfate reduction occurred using ammonia stripped wastewater of the cokes gas liquor. However the phenol decomposition rates were very low. Heterotrophic denitrification occurred using the wastewater. Sulfur denitrification was not suppressed by the addition of the wastewater. Recovered sulfide from the gas liquor was utilized for sulfur denitrification.
