LIQUID CARBON SOURCE COMPOSITION FOR DENITRIFICATION OR DEODORIZATION OF WASTE WATER AND A DENITRIFICATION OR DEODORIZATION METHOD USING IT

摘要

The present invention relates to a liquid carbon source for denitrification or deodorization and a denitrification or deodorization method of waste water by using the same wherein the carbon source comprises an organic acid, a monosaccharide or a disaccharide, and an amino acid. The liquid carbon source for denitrification or deodorization of the present invention: is capable of denitrification and deodorization without having additionally separate equipment for concentrating or fermenting an organic material; can be used regardless of composition of waste water; as a liquid product, can be easily mixed with waste water, thus providing an ease-of-use; does not allow microorganisms to multiply by itself; does not contain methanol and therefore, it is unnecessary to install a separate facility for storing a hazardous substance; provides an easy use and storage; and shows an excellent denitrification efficiency for money, compared with methanol. In addition, the denitrification or deodorizing method by using the liquid carbon source composition of the present invention is capable of: increasing, if inputted in a denitrification step, compared with methanol, a respiration rate of denitrification microorganisms more than five times and increasing the number of microorganisms more than ten times; increasing a production rate of a nitrogen gas more than 30 volume% and thereby, enhancing a denitrification efficiency; activating aerobic microorganisms under aerobic conditions by which a waste water treatment facility is operated and thereby, showing an excellent efficiency to remove an odor generated from anaerobic fermentation products of an organic material; and maintaining stable water quality of discharge water even with sudden fluctuations in a biological load of influent water.
