Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to an aeration device of an MBR membrane bioreactor. Background Art

[0002] MBR membrane bioreactor is a wastewater treatment system that combines traditional bioreactor and membrane separation technology. In the MBR system, the wastewater is first subjected to biodegradation treatment in the bioreactor, and then solid-liquid separation is performed through a microporous membrane, so that solid particles, bacteria, viruses and other substances in the water are retained outside the membrane, while beneficial microorganisms are retained and recycled in the system, thereby improving wastewater treatment efficiency and water quality stability.

[0003] MBR membrane bioreactors usually use aeration devices to provide oxygen and mixed wastewater to meet the needs of microorganisms to degrade organic matter. Compressed air or oxygen is introduced into the sewage to form bubbles and evenly distribute the bubbles in the wastewater to promote the growth of microorganisms and the degradation of organic matter. However, the current aeration devices are not convenient for workers to disassemble and connect them during use. They are troublesome to assemble and operate. Utility Model Content
