Description

Technical Field

[0001] The utility model relates to the technical field of upflow anaerobic sludge blanket reactors, in particular to an upflow anaerobic sludge blanket reactor for treating beer production wastewater. Background Art

[0002] The upflow anaerobic sludge blanket reactor is a highly efficient anaerobic biological treatment technology, which is widely used in sewage treatment and organic waste treatment.

[0003] Common upflow anaerobic sludge blanket reactors are generally evenly distributed to the bottom of the reactor through the water inlet distribution system, and come into contact with the high-concentration, high-activity anaerobic sludge layer at the bottom. Microorganisms decompose organic matter in the wastewater to produce biogas, which rises to the gas chamber at the top of the reactor, while clean water is discharged from the reactor through the overflow weir in the sedimentation area.

[0004] However, since the wastewater from beer production contains a large amount of suspended matter, it will occupy the reactor space and reduce the effective biological treatment area. The suspended matter may also cover the anaerobic granular sludge, hindering the contact between microorganisms and organic matter, and cannot flow evenly into the surface of the reaction zone, causing part of the incoming water to bypass the reaction zone and not fully contact the sludge, resulting in short-circuiting, which in turn affects the operating stability and treatment effect of the entire reactor.
