Abstract

The invention provides equipment for treating waste water by a biochemical technique and a membrane separation technique and in particular relates to self-priming jet aeration external membrane bioreactor waste water treatment equipment. The equipment consists of an integrated bioreactor, a self-priming jet aeration unit and an external membrane separation unit. The equipment has the advantages of integration of the advantages of various water treatment techniques such as deep aeration, a biological fluidized bed, jet aeration, membrane separation, an SBR nitrogen phosphorus removal process and the like, no need of blast aeration equipment, high oxygen transfer utilization efficiency, little residual sludge, long-time stable operation under low energy consumption, readily realized function of removing nitrogen from waste water, good quality of output water, simple process, low fixed investment, small volume and occupied area, convenient operation and management, difficult damage, convenient maintenance, easily realized automatic control and good application prospect in the fields of waste water treatment 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: small footprint, only 1 / 3-1 / 2 of the traditional process; the effluent water quality is good and can b...
