Abstract

The invention discloses a external membrane biological reactor system, which comprises the following steps: including aero-tank and film component; making aero-tank include waste water feed inlet, mixed anoxia section, diving impeller, dividing wall, aerobic section, conveying water pipe and aerated pipe; making film component include box shell and separating film; setting sludge return pipe on the side upper of box shell; connecting with mixed anoxia section of aero-tank; setting filtering medium outlet on the top of box shell; setting blow pipe inlet port and waste water inlet port on the bottom of shell; external connecting air supply with blow pipe inlet port; interconnecting waste water inlet with aerobic section conveying pipe; making separating film with hollow fiber film fibril. This reactor system can remove by man and does not need overhang with cheap cost.

Description

Technical field [0001] The invention relates to a sewage treatment equipment and a sewage treatment method thereof, in particular to an external membrane bioreactor system for sewage treatment and a sewage treatment method thereof. Background technique [0002] Since the 1970s, membrane bioreactors have been used in sewage treatment projects. Membrane bioreactor has found an opportunity for the combination and development of traditional biochemistry and membrane filtration, and has shown its strong vitality in the market. Therefore, it has gradually been widely used in the field of domestic sewage and industrial wastewater treatment. [0003] At present, there are two main forms of membrane bioreactors in the market: submerged membrane bioreactors and external membrane bioreactors. The basic working method is as follows: [0004] Domestic sewage or industrial sewage needs to be pretreated before entering the membrane bioreactor system. For domestic sewage, it is mainly to remove ...
