Abstract

The invention discloses an efficient denitrification treatment method and device applied to high-ammonia-nitrogen wastewater, and belongs to the field of wastewater treatment. A filter screen is arranged in a filter tank of a filter assembly, a water outlet pipe is arranged on one side of the filter tank, a first valve is connected with the water outlet pipe, a nitrification tank of a denitrification assembly is connected with the first valve, stirring blades are arranged in the nitrification tank, a feeding tank is connected with the nitrification tank through a second valve, and a third valve is arranged on the nitrification tank and connected with an aeration tank. According to the invention, sewage in the filter tank can be put into the nitrification tank, then denitrification liquid is put into the nitrification tank through the feeding tank, and the denitrification liquid can be fully mixed through stirring of the stirring blades, so that the subsequent treatment efficiency can be improved, and the problem that the reaction efficiency is reduced due to insufficient mixing in the prior art is solved.

Description

technical field [0001] The invention relates to the field of waste water treatment, in particular to a high-efficiency denitrification treatment method and device applied to high ammonia nitrogen waste water. Background technique [0002] Wastewater denitrification The process of denitrification treatment of wastewater in order to prevent eutrophication of water bodies is generally divided into physical and chemical methods and biological denitrification methods. Physical and chemical denitrification methods include breakpoint oxidation, air stripping or steam steam Nitrification-denitrification biological denitrification method is often used in practice. [0003] In the existing denitrification process, the mixing of wastewater and reaction substances is not sufficient, resulting in a decrease in reaction efficiency. Contents of the invention [0004] The purpose of the present invention is to provide a high-efficiency denitrification treatment method and device for high...
