Abstract

The invention discloses an integrated shortcut nitrification/anaerobic ammoxidation reactor which comprises a reactor body, a base and a support, wherein the reactor body is fixed on the base; the inside of the reactor body is provided with a central shortcut nitrification unit and a peripheral anaerobic ammoxidation unit from the center to the periphery; the central shortcut nitrification unit is divided into a water outlet region, a reaction region and a first water inlet region from top to bottom; a first baffle with a middle grid on the bottom is arranged between both sides of the water outlet region and the peripheral anaerobic ammoxidation unit; the first baffle is fixed on the reactor body; and the peripheral anaerobic ammoxidation unit is divided into a second water inlet region, a first reaction region, a connection region and a second reaction region from inside to outside. According to the invention, the shortcut nitrification unit and the anaerobic ammoxidation unit can be operated independently or be used together, and coupling of two reactions can be realized in the single reactor to treat high ammonia nitrogen wastewater.

Description

technical field [0001] The invention relates to an integrated short-range nitrification / anaerobic ammonia oxidation reactor. Background technique [0002] With the development of industrial and agricultural production and the improvement of people's living standards, the discharge of various types of wastewater has increased sharply, which puts forward higher requirements for wastewater treatment technology. In particular, the massive discharge of high-ammonia-nitrogen wastewater and strict environmental water quality discharge standards have brought great challenges to the removal of high-ammonia-nitrogen wastewater. At present, the biological denitrification technology with microbial technology as the core occupies an irreplaceable position in the treatment of high ammonia nitrogen wastewater. Among them, the new denitrification process anaerobic ammonium oxidation has increasingly become a new force in the wastewater biological denitrification process because of its high...
