MBR membrane bioreactor

 Through the treatment of MBR process, sewage can be reused.The COD removal rate of MBR is greater than 93%, and most suspended

 solids are removed. The effluent quality is good and stable.Applicable to all kinds of office buildings, hotels, restaurants, offices, restaurants,

 restaurants, factories and other domestic sewage and textile, beer, paper, leather, food, oil and other industries organic wastewater 

treatment.MBR is a new water treatment technology combining high efficiency membrane separation technology and activated sludge 

process.The application of hollow fiber membrane can effectively trap microorganisms and nitrifying bacteria in sewage, so that nitrification 

can be carried out efficiently and ammonia nitrogen in water can be removed effectively.At the same time, large organic molecules which 

are difficult to be degraded in sewage were trapped and their residence time in the reactor was prolonged until they were decomposed.

Hollow fiber membrane can well realize mud and water separation, so that the activated sludge is not lost and the sludge age is improved

. Therefore, MBR does not need the secondary sedimentation tank in the traditional process.The MBR bioreactor is controlled by programm

able logic controller (PLC).It has the following functions: the whole process of membrane bioreactor adopts automatic control system,

 which greatly reduces the operation and management cost.The feed pump runs automatically.When the water in the bioreactor reaches 

the high water level, the feed pump stops running, and when the water level drops to the low water level, the feed pump automatically 

opens.Automatically open and close the circulating pump according to the water level of the reservoir.Automatically open and close the

 dosing pump, dosing amount can be adjusted as required.Automatically run the film cleaning program.The motor is equipped with

 overcurrent and overload protection.

Membrane biological reactor is a new and efficient sewage treatment technology which combines membrane separation technology and 

biological technology.The role of the membrane is to replace the secondary sedimentation tank, to trap organisms in a bioreactor,By 

maintaining high biological concentrations and intercepting high molecular weight solutes, mineralization of influent organisms is 

promoted without subsequent treatment. Compared with conventional technology, it has the following characteristics:

1.The removal efficiency of contamination is high, which can not only efficiently separate solid and liquid, but also effectively remove 

pathogenic microorganisms.

2.The concentration of microorganisms in the bioreactor was high, and MLSS was 3-10 times of the conventional treatment process.

Therefore, the reactor has a large solvent load, compact equipment and less floor space.

3.The adsorption and long-term contact of high concentration activated sludge make the residence time of slow decomposition of large

 molecules of organic matter become longer, so that its degradation rate increases, sludge production is less, effluent water quality is 

stable.4.Due to the mechanism of filtration and separation, it is not afraid of sludge swelling, and the effluent from membrane filtration

 and interception will not affect the effluent quality even if sludge swelling occurs.

5.The amount of surplus sludge is small, and the sludge treatment and disposal costs are low.Due to the long SRT and high sludge 

concentration, the bioreactor ACTS as an aerobic sludge digester, which can eliminate sludge concentration tank and sludge digester, and 

also saves the basic investment and operation cost of sludge treatment.
