Abstract

The invention discloses equipment for processing the wastewater through a biochemical technology and a membrane separating technology, and particularly relates to external membrane bioreactor wastewater processing equipment with a self-suction jet nozzle aerating function. The equipment comprises an integrated bioreactor, a self-suction jet nozzle aerating unit and an external membrane separating unit. The wastewater processing equipment, which integrates advantages of deep aeration, a biological fluidized bed, jet aeration, membrane separation, a sequencing batch reactor (SBR) nitrogen and phosphorus removal technology and other water treatment technologies, and is high in oxygen transfer utilizing efficiency, free from air-blowing aerating equipment, low in residual sludge, and capable of realizing a long-term stable operation with low energy consumption. The equipment is good in quality of discharged water, compact in process, small in occupied area, low in investment, convenient in maintenance and easy to realize the automatic control. The equipment has a good application prospect in the field of wastewater processing and recycling.

Description

technical field [0001] The invention belongs to equipment for treating waste water using biochemical technology and membrane separation technology, in particular to a self-priming jet aeration external membrane bioreactor waste water treatment equipment. Background technique [0002] Membrane bioreactor is a combination of traditional activated sludge method and membrane separation technology. The microorganisms in the activated sludge biodegrade the organic matter in the raw water to achieve the purpose of removing the organic matter. The membrane separation unit replaces the secondary settling tank in the traditional process, and can intercept solid suspended matter and colloidal substances in the raw water to ensure high-quality and stable effluent water quality. Compared with the traditional water treatment process, the membrane bioreactor has the following advantages: it occupies a small area, only 1 / 3~1 / 2 of the traditional process; the effluent water quality is good ...
