Technical Field

[0001] This utility model relates to the field of anaerobic reactors, and in particular to an anaerobic reactor for treating brewing wastewater. Background Technology

[0002] Brewing wastewater has a complex composition, containing BOD, COD, organic matter, and polyphenols, all of which can cause serious environmental pollution. Existing brewing wastewater treatment typically uses anaerobic reactors, which utilize various microorganisms inside the reactor to degrade the organic matter in the wastewater.

[0003] Among the existing technologies, the anaerobic reactor for treating brewing wastewater, authorized by announcement number CN212954735U, includes a tank. The tank is equipped with a water distributor, a primary three-phase separator, and a secondary three-phase separator. The tank is also equipped with an ascending pipe and a descending pipe. The other side of the descending pipe passes through the secondary three-phase separator and is located inside the rotary gas-liquid separator. The upper end of the rotary gas-liquid separator is equipped with an exhaust pipe. The side wall of the tank is equipped with an exhaust pipe and an inlet. A filter block is fixed at one end of the inlet, and an inlet pipe is provided at one end of the filter block.

[0004] Existing static filtration devices are easily clogged by large particulate pollutants, requiring frequent shutdowns for manual cleaning, which severely affects continuous operation, increases operating costs, and makes it difficult to maintain stable temperature and water level conditions, thus affecting the activity of anaerobic bacteria. They are particularly unsuitable for the intermittent discharge of brewing wastewater. Therefore, we propose an anaerobic reactor for brewing wastewater treatment. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide an anaerobic reactor for treating brewing wastewater, which can filter and clean large particulate pollutants.
