METHOD FOR MANUFACTURING DENITRIFICATION CARBON SOURCE COMPOSITION USING WASTEWATER CONTAINING SODIUM SULFATE OF BIODIESEL BY-PRODUCT

摘要

The present invention discloses a method for manufacturing a denitrification carbon source composition, comprising the steps of: (a) preparing wastewater containing sodium sulfate which is a by-product of biodiesel production; (b) mixing and reacting a divalent cation compound capable of binding with sulfuric acid of sodium sulfate to form a sulfate in a form of a precipitate, with the wastewater containing sodium sulfate; and (c) removing sulfate in the form of a precipitate formed after the reaction and recovering the liquid wastewater.;COPYRIGHT KIPO 2018
