Short-cut nitrification and denitrification coupled anaerobic ammonia oxidation denitrification reactor and integrated equipment

Abstract

The invention discloses a short-cut nitrification and denitrification coupled anaerobic ammonia oxidation denitrification reactor and complete equipment, and belongs to the field of sewage treatment. The device comprises a tank body, a filler module and a circulating pipeline, the tank body comprises a lower-section sludge hopper, a middle-section central water inlet pipe and a filler area which are arranged from bottom to top in the vertical direction, and a heater is mounted on an upper-section circulating pump water inlet pipe; an aerator pipe is arranged in the sludge hopper; a sludge discharge pipe is arranged at the lower section; the central water inlet pipe is fixed on the filler module bracket; an annular water distributor is mounted at the lower section of the central water inlet pipe through a flange; the spherical mounting fillers are made into strings and fixed in the filler frame, and the filler frame is placed on the filler module support. And an insulating layer, a sampling port and a top cover plate are arranged outside the tank body. By strictly controlling the dissolved oxygen concentration and temperature in the reactor, short-cut nitrification and denitrification coupled anaerobic ammonia oxidation high-efficiency denitrification can be realized, so that the aim of purifying water is fulfilled.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a short-range nitrification and denitrification coupled anammox denitrification reactor and short-range nitrification and denitrification coupled anammox denitrification reactor integrated equipment. Background technique [0002] The leachate of the domestic waste landfill has complex components, contains a large amount of toxic and harmful substances, heavy metals, etc., and has the characteristics of high ammonia nitrogen and high organic matter concentration, and the organic pollutants are mainly non-biodegradable compounds, which leads to the carbon-nitrogen ratio of the leachate. If it is seriously unbalanced, if it is directly discharged into the environment without proper disposal, it will cause great potential harm to the surrounding environment. Therefore, the landfill leachate must be treated and discharged up to the standard. At present, the traditional nitrification an...
