Micro-vortex internal circulation anaerobic bioreactor

Abstract

The invention discloses a micro-vortex internal circulation anaerobic bioreactor structurally comprising a biogas pipe, a water outlet pipe, a purification cabin and a water inlet; the biogas pipe is movably clamped to the center of the upper end of the purification cabin, the water outlet pipe is fixedly connected to the side edge of the upper end of the purification cabin in an embedded mode, and the water inlet is fixedly connected to the left side of the lower end of the water outlet pipe in an embedded mode; the purification cabin is composed of a walkway plate, a separation layer, an ascending pipe, a water distributor and a descending pipe; the walkway plate is connected to the outer side of the walkway plate in a meshed mode; the separation layer is located at the upper end of the water distributor, the ascending pipe is vertically connected to the center of the water distributor, and the water distributor is arranged at the lower end of the descending pipe; in the purification process of the water distributor, a contact frame in an extension device is used for moving at a water distribution hole; and in the moving process, a sharp dredging block on the inner side of a dredging belt rub the lower end of the water distribution hole plate, then sludge adhering to holes is scraped off, the holes are prevented from being blocked, and thus it is guaranteed that the inner side of the water distribution hole are clean and tidy, and the use benefits of the water distributor are improved.

Description

technical field [0001] The invention belongs to the field of bioreactors, and more specifically relates to a microvortex internal circulation anaerobic bioreactor. Background technique [0002] The internal circulation anaerobic reactor is an efficient waste treatment device. It uses sand and other materials as carriers, and the wastewater flows from the reactor from top to bottom. The water distributor is used to promote anaerobic microorganisms to enter the bottom of the reactor. The reactor is in full contact with the granular sludge and anaerobic sludge, so that the pollutants are adsorbed and decomposed, and then flow out from the upper part of the reactor after purification. [0003] Based on the inventor's discovery above, the existing methods mainly have the following deficiencies, such as: when anaerobic microorganisms flow through the water distributor, the sludge flows into the water distributor in flocculent form, and the water distribution holes of the water dis...

Problems solved by technology

[0003] Based on the inventors' findings above, the existing methods mainly have the following deficiencies, such as: when anaerobic microorganisms flow through the water distributor, the sludge flows into the water distributor in flocculent form, and the water distribution holes of the water distributor It is vertically connected to the inner side, and when it flows in, it will flow along the edge of the hole, which will cause some granular sludge to stay in the corner of the edge of the water distribution hole or stick to the surface of the inner wall of the hole, and the continuous accumulation of water will make the sludge The water distribution hole is completely covered, which makes the water distribution hole blocked and affects its water distribution effect
