Abstract

PURPOSE: To attain the high efficiency of denitrification, the positive washing of denitrifying media and continuous opeation by a method wherein a current of nitrating water is formed in an upward current, and dispersed so as to contact with denitrifying media sufficiently, to denitrifying media are lifted by air to remove microbes adhering to the media, and the denitrifying media wahsed are returned.
CONSTITUTION: When nitrating water Ni is flowed into wach inflow pipe 4 from an introducing pipe 2 in case of denitrifying treatment, the nitrating water rises in the inflow pipes 4, collides with dispersing hoods 5 and is dispersed into the media 3. When the nitrating water passes through the media 3, it is subjecte to a denitrifying reaction by denitrifying bacteria existing among the media 3. Nitrogen gases formed as the results rise in a tank 1, and are diffused from the upper portion. Denitrified water De is collected to a denitrified water collecting gutter 11, and discharged. When a medium layer is clogged by the breeding of microbes, meanwhile, air A is sent into a washing pipe 6, the media 3 and water in the tank 1 rise in the washing pipe 6 by an air lift effect, the media 3 are subject to violent agitation action, and the microbes adhering to the meda 3 are exfoliated.
