Abstract

The invention relates to a water recycling treatment technology, and particularly relates to a method for solving membrane bio-reactor (MBR) membrane blocking and a composite MBR membrane bio-reaction system. A sewage treatment tank of a water treatment system adopting the MBR membrane and activated sludge attached with microorganisms is partitioned into at least two treatment regions; an MBR membrane is arranged in one treatment region; the other treatment region is a pretreatment region; the activated sludge attached with the microorganisms is arranged into the pretreatment region. The system comprises a waste water tank, a sewage treatment tank, a hair dreg collector, and an MBR membrane, wherein the sewage treatment tank is communicated with the waste water tank through a drain pipe; the hair dreg collector is arranged on the drain pipe; the MBR membrane is arranged on the sewage treatment tank; the sewage treatment tank comprises an MBR membrane pretreatment tank and a pretreatment region, which are independent. The blocking probability of the MBR membrane is reduced, the service life of the MBR membrane is prolonged, and the use cost is reduced.

Description

technical field [0001] The invention relates to a water reuse treatment technology, in particular to a method for solving MBR membrane clogging and a composite MBR membrane bioreaction system for reducing the probability of MBR membrane clogging, prolonging the service life of the MBR membrane and reducing the use cost. Background technique [0002] The MBR membrane bioreaction system is divided into two types: built-in type and external type according to the use status of the MBR membrane. The built-in type is to directly immerse the MBR membrane in the biochemical reaction tank, and directly pump out the purified water from the MBR membrane unit, while the external type uses a pump to pass the water in the biological reaction tank through the MBR membrane module for cross-flow filtration and circulation to obtain clean permeation. water. [0003] The built-in MBR membrane reaction system uses a large membrane area due to its low operating pressure, while the external MBR ...
