Description

A kind of MBR membrane modules
Technical field
The utility model is related to sewage disposal device, more specifically to a kind of MBR membrane modules.
Background technology
In recent years, application of the membrane technology in sewage treatment field is particularly the membrane bioreaction combined with bioreactor Device (Membrane Bioreactor, abbreviation MBR) technique is answered to be received increasingly as a kind of new and effective sewage treatment process Extensive concern.MBR is a kind of novel water technology for mutually tying platform with biological processing unit by film separation unit, with membrane module Substitution secondary settling tank keeps high activity sludge concentration to reduce sewage treatment facility occupation of land in the bioreactor, and passes through and keep low dirt Mud load reduces sludge quantity.There is MBR techniques easy to operate, hydraulic detention time (HRT) to be detached with sludge age (SRT), sludge The advantages that concentration is high, capacity of resisting impact load is strong, effluent quality is good.In membrane bioreactor, bioreactor is mainly completed The degradation of dirty water pollutant;Film separation unit mainly completes separation of solid and liquid and some macromolecular compounds is played with retention work With used film is generally ultrafiltration or microfiltration membranes.
In practical applications, since the membrane module of MBR in the process of running is vulnerable to pollution, flux depression, shadow are caused The stable operation of membrane module is rung, fouling membrane is made to become the critical issue of limitation MBR applications.Fouling membrane refers to suspended particulate, colloid Particle or dissolubility larger molecular organics are caused membrane aperture to reduce or block, lead to film in film surface and fenestra interior suction adventitious deposit The phenomenon that amount declines.
