This article introduces in detail Jiefu MBR Membrane work content and mbr Advantages of sewage treatment process
I MBR The steps in membrane operation can be described as follows:
Sewage passing through 1-2mm Geshan is injected into the sewage pool, where the seepage water body and water flow adjustment ; The residues blocked by the grid deletion must be removed on time. Below, the sewage in the sewage pool is pumped to mbr System, on mbr The system completes the dissolution and reduction of pollutants by microbial strains, including aerobic and anoxic reaction areas. The insoluble residues and activated sludge membrane components are separated and then left in the membrane tank. The filtrate produced by activated carbon filtration shall be recycled or discharged as qualified.

II mbr Characteristics of sewage treatment process:
1) The unique time water softener, organic chemical softener and chemical water treatment process are selected to ensure the water production capacity and membrane flux of membrane components.
2) Transmembrane working pressure (TMP) Low, usually zero point zero one ～ 0.06MPa , siphon principle can be applied without additional aspiration The driving force can produce water, and the operating cost of system software is low.
3)mbr The processing technology is composed of anoxic and aerobic components. The sewage flows into the anoxic zone, where the long-chain organic compounds with large relative molecular weight are dissolved into small molecular water organic compounds that are easy to be biochemical, and then the sewage flows into the aerobic zone for organic compound degradation. At the same time, the biological weight nitridation reaction is carried out, and the hydrolysis acidification tank is carried out according to the flow back to the anoxic zone for denitrification.
In the aerobic area, the following chemical changes are carried out under the effect of water quality stabilizer:
2NH4++3O2 → 2NO2-+4H++2H2O
2NO2-+O2 → 2N03- 。
Anoxic zone . The following chemical changes are carried out under the effect of anti water quality stabilizer:
6NO3-+2CH30H → 6NO2-+2CO2 ↑ +4H20
2N02-+3CH3OH → 3N2 ↑ +3H20+60H-+3C02 。
Summary mbr It is a new sewage treatment technology that closely combines denitrification and integrated immersion membrane separation technology system software. This whole process can be widely used in municipal engineering and industrial production sewage treatment industry, including water reuse, community development, ecological parks and tourist attractions. As a new sewage treatment technology, MBR It has been widely used in sewage treatment plants around the world.
mbr It is a new sewage treatment technology combining high-efficiency membrane separation equipment and biotechnology. It inherits the technical advantages of membrane separation equipment and biochemical solutions and strengthens the practical effect of biochemical solutions.
