Embodiment 1
[0030] Embodiment 1: as figure 1 As shown, the anaerobic methanogenic anammox joint treatment soybean protein wastewater device is provided with an inlet water tank 1, and the water inlet water tank 1 communicates with the anaerobic SBR reactor 3 through the first water inlet pump 2 and pipelines;
[0031] Anaerobic SBR reactor 3 is provided with reaction zone 5, top zone 6, and the bottom of reaction zone 5 is provided with the microporous aeration head 4 that is communicated with air compressor, and reaction zone 5 top is top zone 6; A first overflow weir 7 is arranged between the regions 6, and the outside of the first overflow weir 7 communicates with the water outlet pipeline 8; a gas outlet 9 and a gas return pipeline 10 are arranged at the top of the reaction zone 5;
[0032] The air compressor that is communicated with the microporous aeration head 4 is provided with two, and one of them is the air return compressor 11, and its air inlet passes through the gas return l...
Embodiment 2
[0037] Embodiment 2: as figure 1 As shown, the anaerobic methanogenesis anaerobic ammonia oxidation combined treatment soybean protein wastewater device is divided into two parts, both of which use filler sludge as the carrier. Among them, the anaerobic SBR reactor is enriched with methanogenic bacteria to effectively remove organic matter in water; the denitrification SBR reactor is enriched with ammonia oxidizing bacteria and anaerobic ammonia oxidizing bacteria at the same time, and the economical and efficient denitrification can be achieved through the synergy of the two bacteria . The process is suitable for the treatment of soybean protein production wastewater, and can effectively remove COD and ammonia nitrogen in wastewater; it also has a good treatment effect on other wastewater with high C / N ratio.
[0038] The device for combined treatment of soybean protein wastewater by anaerobic methanogenesis and anaerobic ammonium oxidation of the present invention consists ...
