Efficient anaerobic bioreactor for industrial wastewater treatment

Abstract

The invention discloses an efficient anaerobic bioreactor for industrial wastewater treatment, which belongs to the field of anaerobic bioreactors. A self-descending cleaning ball and a floating cleaning ball are respectively arranged, on one hand, when biogas ascends along a lifting pipe, airflow can drive the self-descending cleaning ball to move upwards, and under the gravity action of the self-descending cleaning ball, theself-descending cleaning ball can move up and down irregularly to realize the dredging of the lifting pipe and the self-cleaning of the self-descending cleaning ball; on the other hand, when the mud-water mixture flows back downwards along the backflow pipe, in combination with the buoyancy of the mud-water to the floating cleaning ball and the thrust of the mud-water mixture to the floating cleaning ball when the mud-water mixture falls down, the floating cleaning balls are dispersed and distributed in the backflow pipe along with mud water, the soft ball shells contract inwards to extrude a mud water mixture and promote the mud water mixture to flow downwards through the gravitational action between the floating cleaning balls and the magnetic sheets, meanwhile, the floating cleaning balls are pushed to dredge the inner wall of the backflow pipe, and the dredging process of the backflow pipe is achieved.

Description

Technical field [0001] The present invention relates to the field of anaerobic bioreactors, and more specifically, to an efficient anaerobic bioreactor for industrial wastewater treatment. Background technique [0002] Anaerobic reaction is a process that uses microorganisms to convert organic pollutants COD into biogas CH4 in the absence of oxygen. Anaerobic reactors are widely used in light industrial industries such as food, beverages, fermentation, papermaking, and landfill leachate. Among them, IC anaerobic reactor has the advantages of high processing load, small footprint, strong impact resistance, stable operation, and high reliability. It is mainly used for the treatment of high-concentration organic wastewater, wastewater with high SS content or toxic to microorganisms. , the principle is as follows: [0003] The wastewater is input into the reactor through the water distributor and enters the first reaction zone, which is the fluidized bed reaction chamber, where...

Problems solved by technology

[0004] However, the mud-water mixture riser and return pipe involved in the internal circulation process of the existing IC anaerobic reactor are prone to blockage, which affects the efficiency of the internal circulation in mild cases, and paralyzes the internal circulation in severe cases, thereby affecting the normal use of the reactor.
