Embodiment Construction
[0016] This equipment is composed of biological denitrification reactor 1, water tank 2, balance water tank 3, liquid flow meter 4, gas flow meter 5, air compressor 6, air pusher 7, mud discharge hole 8, water outlet 9, etc. The biological denitrification reactor is made of anti-corrosion carbon steel material, and the volume of the aeration area is 60-100L.
[0017] The incoming water is a continuous flow, and the incoming water and the return water of the sedimentation tank are mixed into the air push flow area, and the compressed air of the air compressor pushes the incoming water into the aeration area through the air pusher, and the aeration area adopts a microporous aerator. Aeration, the effluent enters the anoxic zone, and after the denitrification reaction in the anoxic zone, the effluent enters the sedimentation zone, which is a slanted plate sedimentation tank, and part of the effluent of the sedimentation tank is discharged, and part of it enters the air push flow z...

The invention relates to a sewage treatment device and specifically relates to an integrated short-cut nitrification and denitrification biological nitrogen-removal reactor which is used for solving the current situation that the existing short-cut nitrification and denitrification biological nitrogen-removal process equipment is large in floor space and high in capital expenditure, needs to be controlled by professional personnel in operating and debugging, and is very complex to operate and manage. The equipment is organically combined with an air plug-flow zone, an aeration zone, an anoxic zone and a settling zone to form an integrated reactor. The equipment consists of a biological nitrogen-removal reactor 1, a water tank 2, a balanced water tank 3, a gas flow rate meter 5, an air compressor 6, an air impeller 7, a mud exhausting hole 8, a water outlet 9, and the like. The equipment can be used for realizing a stable short-cut nitrification and denitrification process, and has the advantages of being simple in structure, small in floor space, low in power consumption, high in oxygen transmission efficiency and high in automation control degree. The reactor disclosed by the invention can be suitable for various nitrogen-containing sewage treatment, is good in treatment effect and stable in outlet water quality.
Description
technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to an integrated short-range nitrification and denitrification biological denitrification reactor. Background technique [0002] Nitrogen-containing wastewater is directly discharged into the water body without treatment or improper treatment, which will lead to eutrophication of the water body, cause water pollution, reduce the environmental quality of the water body, and endanger the entire ecosystem. Therefore, in recent years, people have begun to pay attention to the impact of nitrogen pollution on the environment, and gradually carry out various projects for nitrogen pollution control, and various processes for denitrification treatment have been developed in the field of sewage treatment technology. [0003] At present, the main treatment technologies for nitrogenous wastewater at home and abroad mainly include the following types: physical method, chemical...
