METHOD FOR IMMOBILIZING NITROGEN-REMOVING BACTERIA

摘要

PURPOSE: A method for immobilizing nitrogen-removing bacteria is provided, thereby the growth rate of nitrogen-removing bacteria can be improved. CONSTITUTION: The nitrogen-removing bacteria are immobilized into the fiber contact material coated with ammonia nitrogen and inorganic elements using agar, in which the nitrogen-removing bacteria nitrifies ammonia nitrogen into nitrate nitrogen. The nitrogen is removed from wastewater by passing the wastewater through the first reactor containing conventional fiber contact material where carbon using bacteria grow well then through the second reactor containing the fiber contact material coated with ammonia nitrogen and inorganic elements where nitrogen-removing bacteria grow well.
