Hollow fiber membrane biological reaction component and membrane biological reaction device

Abstract

The invention discloses a hollow fiber membrane biological reaction component and a membrane biological reaction device. The membrane biological reaction component comprises a plurality of hollow fiber membrane biological reaction units, wherein each biological reaction unit comprises a water collecting membrane box and two hollow fiber membrane biological reaction elements; and the membrane biological reaction device comprises a membrane bracket, a water collecting header pipe, an aeration device and a plurality of hollow fiber membrane biological reaction components. The hollow fiber membrane biological reaction component is formed by connecting and assembling the plurality of hollow fiber membrane biological reaction units and a plurality of pipe seal heads and has the characteristics of simple structure and convenience in detachment and installation, when the hollow fiber membrane biological reaction element is locally blocked by sludge or damaged, the element can be conveniently repaired or replaced; and meanwhile, sludge attached to the surface of the hollow fiber membrane can be effectively prevented, the possibility that the hollow fiber membrane filament is broken is reduced, the pollution resistance of the hollow fiber membrane filament is improved, the solid-liquid separation rate of the hollow fiber membrane filament is increased, the effluent quality is improved, and the service life of the hollow fiber membrane filament is prolonged.

Description

technical field [0001] The invention relates to a membrane bioreaction sewage treatment device, more specifically, to a hollow fiber membrane bioreaction module and a membrane bioreaction device including the membrane bioreaction module. Background technique [0002] With the continuous development of sewage treatment technology, membrane biological reaction treatment technology has gradually become the mainstream. Membrane biological reaction treatment technology, also known as membrane separation activated sludge method, is a technology that combines membrane technology with biochemical reactions in sewage treatment. Among them, the membrane bioreactor used uses membranes to filter the muddy sewage in the biochemical reaction tank to realize the separation of muddy water. On the one hand, the membrane retains the microorganisms in the reaction tank, greatly increasing the concentration of activated sludge in the tank, so that the biochemical reaction of degrading sewage c...
