Method for carbon source of biological denitrification using distillery wastewater

摘要

PURPOSE: A method for reusing distillery wastewater as carbon source for biological denitrification process is provided. CONSTITUTION: The method comprises the steps of dehydrating waste distillery wastewater to remove suspended solids, phosphate and nitrogen therefrom, thus obtaining a cake; adjusting pH of centrate generated from the dehydration process; feeding NaOH to the centrate after pH adjustment for hydrolysis of the centrate; and fermenting the centrate after the hydrolysis process.
