Description

MBR (membrane bioreactor) membrane assembly capable of retarding pollution

Technical Field

The utility model relates to a sewage treatment device field, concretely relates to MBR membrane module that slows down pollution.

Background

MBR membrane bioreactor is a new type of state wastewater treatment system that organically combines membrane separation technology and biological treatment technology. The membrane component replaces a tail end secondary sedimentation tank of the traditional biological treatment technology, keeps high active sludge concentration in a bioreactor, improves the organic load of biological treatment, thereby reducing the occupied area of sewage treatment facilities and reducing the amount of excess sludge by keeping low sludge load. Mainly utilizes the membrane separation equipment immersed in the aerobic biological tank to trap the activated sludge and macromolecular organic matters in the tank. Most of the MBR membrane filtration systems have the processes of precipitation, aeration and the like, but reaction residues such as precipitates, fibers and the like are attached to the surface of the MBR membrane during filtration, so that the surface of the MBR membrane is blocked, and the MBR membrane is blocked due to excessive attachments, so that the filtration efficiency is gradually reduced, frequent cleaning and maintenance are needed, and the MBR membrane filtration systems are troublesome and labor-consuming, so that the MBR membrane filtration systems have an improvement space.
