[0022] By adopting the above technical solution, the primary separation zone 16 and the secondary separation zone 18 work together with the primary gas collection zone 15 and the secondary gas collection zone 17 to accurately separate the gas, liquid and solid phases, reduce sludge loss, ensure long-term stable operation of the reactor, and avoid the problem of a sharp drop in efficiency caused by sludge loss in traditional reactors.

[0023] In this embodiment, a drainage port 19 is provided on one side of the upper end of the reactor body 11, and the upper end of the reactor body 11 is fixedly connected to the top cover plate 21. The top cover plate 21 is respectively connected to the internal circulation pipe 23, the first biogas lifting pipe 24 and the second biogas lifting pipe 25. The upper ends of the internal circulation pipe 23, biogas lifting pipe one 24 and biogas lifting pipe two 25 are connected to the inside of the gas-liquid separation chamber 22, and the lower end of the gas-liquid separation chamber 22 is fixedly installed on the upper surface of the top cover plate 21. The lower ends of the internal circulation pipe 23, biogas lifting pipe 1 24 and biogas lifting pipe 25 are respectively connected to the inner side of the sludge cover 14, the inner side of the primary gas collection zone 15 and the inner side of the secondary gas collection zone 17, and a flow regulating valve 211 is installed on the internal circulation pipe 23; a biogas discharge port 26 is provided at the top of the upper end of the gas-liquid separation chamber 22.

[0024] By adopting the above technical solution, the internal circulation pipe 23, combined with the flow regulating valve 211, achieves high-multiplication circulation of the mixed liquid, greatly enhances mass transfer efficiency, increases volumetric load, and accelerates organic matter degradation; the biogas riser pipe 1 24 and biogas riser pipe 25, together with the gas-liquid separation chamber 22 and the overflow biogas chamber 28, efficiently collect biogas, increase energy recovery, and have both environmental and economic benefits, adapting to the energy treatment needs of high-concentration organic wastewater; The electromagnetic control valve 12 and the flow regulating valve 211 can be dynamically adjusted according to the influent load, buffering the impact of high-concentration wastewater, solving the problem of weak impact resistance of traditional reactors, and adapting to the fluctuating conditions of industrial wastewater.

[0025] The working principle of this utility model is as follows: wastewater enters the reactor body 11 through the inlet pipe 13 and the electromagnetic control valve 12, and is evenly distributed under the action of the sludge cover 14, mixing with the high concentration of granular sludge at the bottom; at this time, the large molecular organic matter in the wastewater begins to hydrolyze and acidify, and is initially degraded into small molecular substances; The primary gas collection zone 15 collects biogas produced in the first reaction zone and transports it to the gas-liquid separation chamber 22 via biogas lift pipe 1 24. The primary separation zone 16 achieves gas-liquid-solid separation. The sludge falls back into the reaction zone, while the mixed liquid, due to the lift of the biogas, forms an internal circulation through the internal circulation pipe 23 and the flow regulating valve 211, enhancing mass transfer and degradation. The secondary gas collection zone 17 and the secondary separation zone 18 repeat the separation process to deeply treat residual organic matter. The biogas enters the gas-liquid separation chamber 22 via biogas lift pipe 2 25. The gas-liquid separation chamber 22 separates biogas and mixed liquid. The biogas is collected and utilized through the biogas discharge port 26, the overflow biogas chamber 28, and the second biogas discharge port 29. The treated clean water is discharged through the drainage interface 19, completing the closed loop of wastewater purification and energy recovery. The internal circulation pipe 23, combined with the flow regulating valve 211, enables high-multiplication circulation of the mixed liquid, significantly enhancing mass transfer efficiency, increasing volumetric load, and accelerating organic matter degradation. The biogas lift pipe 1 24 and biogas lift pipe 25, in conjunction with the gas-liquid separation chamber 22 and the overflow biogas chamber 28, efficiently collect biogas, increase energy recovery, and combine environmental and economic benefits, meeting the energy treatment needs of high-concentration organic wastewater. The primary separation zone 16 and the secondary separation zone 18 work in conjunction with the primary gas collection zone 15 and the secondary gas collection zone 17 to accurately separate the gas, liquid and solid phases, reduce sludge loss, ensure long-term stable operation of the reactor, and avoid the problem of a sharp drop in efficiency caused by sludge loss in traditional reactors. The electromagnetic control valve 12 and the flow regulating valve 211 can be dynamically adjusted according to the influent load, buffering the impact of high-concentration wastewater, solving the problem of weak impact resistance of traditional reactors, and adapting to the fluctuating conditions of industrial wastewater.
