<P>PROBLEM TO BE SOLVED: To provide a treatment method which selectively uses a granule bacterium obtained from treatment of molasses-based food processing waste water especially as a denitrifying bacterium granule, cultivates and habituates the granule bacterium in industrial wastewater of high nitrogen concentration and high salts concentration, forms the highly active granule bacterium, and quickly denitrates as it is without dilution of the industrial wastewater of high nitrogen concentration and high salts concentration by the highly active granule bacterium. <P>SOLUTION: The granule bacterium obtained from treatment of the molasses-based food processing waste water especially even in a methane bacterium granule excellent in viability for the industrial wastewater of high nitrogen concentration and high salts concentration, is selectively used. The granule bacterium is cultivated and habituated in the industrial wastewater of high nitrogen concentration and high salts concentration to form the highly active granule bacterium. Therefore, denitration treatment is quickly carried out as it is even though the industrial wastewater of high nitrogen concentration and high salts concentration is not diluted. <P>COPYRIGHT: (C)2012,JPO&INPIT |
