In the article MBR membrane Work content, characteristics of mbr sewage treatment process and relevant performance parameters of MBR membrane.

I The working process of MBR membrane can be described as follows:

Wastewater passing through 1-2mm grid is injected into the sewage pool, where the seepage water quality and water consumption are adjusted; The residue shielded by the grid must be removed regularly. Next, the waste water in the sewage pool is pumped to the mbr system, where the microbial strains are dissolved to reduce pollutants, including aerobic and anoxic reaction areas. The insoluble sundries and activated sludge are separated by membrane modules and then left in the membrane pool. The filtrate produced by activated carbon filtration shall be recycled or discharged as qualified.

II Mbr sewage treatment process characteristics:

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 the membrane module.

2) The transmembrane working pressure (TMP) is low, generally 0.01~0.06MPa. Water can be produced by using the siphon principle without additional liposuction driving force, and the operating system cost is low.

3) The mbr process is composed of anoxic and aerobic components. The waste water goes first to the anoxic zone, where the large amount of long-chain organics are decomposed into small molecule organics that are easy to be biochemical, and then the waste water goes to the aerobic zone to carry out organic compound degradation, carry out microbial diazotization reaction simultaneously, and carry out hydrolysis acidification tank for denitrification by flowing back to the anoxic zone.

In the aerobic zone, the following chemical changes are carried out during the action of nitrifying bacteria:

2NH4++3O2→2NO2-+4H++2H2O

2NO2-+O2→2N03-。

Anoxic zone The following chemical changes are carried out during the action of denitrifying bacteria:

6NO3 -+2CH30H → 6NO2 -+2CO2 hypoxia+4H20

2N02 -+3CH3OH → 3N2 hypoxia+3H20+60H -+3C02.

Summary Mbr is a new sewage treatment technology that combines activated sludge and integrated submerged membrane separation system. This process can be widely used in municipal engineering and industrial wastewater treatment industry, including water source recycling, community development, water source recycling of ecological parks and tourist attractions. As a new sewage treatment technology, MBR has long been widely used in sewage treatment stations around the world.

Mbr is a new sewage treatment technology combining high-efficiency membrane separation equipment with biochemical technology. It inherits the characteristics of membrane separation equipment and biochemical treatment technology and strengthens the practical effect of biochemical treatment.
