Summary:PROBLEM TO BE SOLVED: To increase a decolorizing function and a denitrification function in a biological denitrification process of an organic wastewater disposal method for enhancing the denitrification function and the decolorizing function of organic wastewater to reduce a load in the post-stage of the biological denitrification process. SOLUTION: In the organic wastewater disposal method including the biological denitrification process, a ozone treatment is performed in the pre-stage of the biological denitrification process and the ozone treatment is performed in the post-stage of the biological denitrification process as high treatment. The waste ozone generated from the ozone treatment is circulated to wastewater in the pre-stage of the biological denitrification process.
