Send InquiryIntroduction
Membrane Bio-Reactor (MBR) is a new high-efficiency wastewater treatment process combining biological treatment technology and membrane separation technology. It uses anoxic and aerobic organisms to degrade organic pollutants and efficiently separates membrane components. The function is to completely separate the mud and water, and the effluent is clear and transparent, which can be directly reused.
Membrane bioreactor equipment overcomes the shortcomings of the traditional "contact oxidation + filtration" treatment process that the effluent cannot meet the standard requirements stably, and the process is too long, covers a large area, has large sludge discharge, and has a large amount of operation and maintenance workload. The membrane separation is organically combined with traditional biochemical treatment, and the water quality is purified through a one-step unit operation. The sedimentation tank is omitted, the floor space is greatly saved, and the membrane pore size reaches 0.1 micron, so that the tiny impurities in the sewage are completely retained, the turbidity of the effluent is close to zero, and it is clear and transparent.

Equipment characteristics
(1) High efficiency. The process has a high removal effect on the organic matter ammonia nitrogen in the wastewater. When the total residence time is greater than 54h, the effluent after biological denitrification and coagulation sedimentation can reduce the COD value to less than 100mg / L. Other indicators also reach the emission standard. The total nitrogen removal rate is above 70%.
(2) Simple process investment and low operating cost. The process uses organic matter in wastewater as a carbon source for denitrification, so no additional expensive carbon source such as methanol is needed. In particular, the carbon-to-nitrogen ratio is increased after the ammonia distillation device is provided with a device for defixing ammonia, and the alkalinity generated in the denitrification process correspondingly reduces the alkali consumption required for the nitrification process.
(3) Anoxic denitrification process has high degradation efficiency for pollutants. For example, the removal rate of COD, BOD5 and SCN- in the anoxic zone is 67%, 38%, 59%. The removal rates of phenol and organic matter are 62% and 36% respectively. Therefore, the denitrification reaction is an economical and energy-saving degradation process.
(4) The volume load is high. Because the enhanced biochemical denitrification stage and the high-concentration sludge membrane technology are used in the nitrification stage, the nitrification and denitrification sludge concentrations are effectively increased compared with similar foreign processes, which have a higher volume load.
(5) The load-bearing shock resistance of the anoxic / aerobic process is strong. When the quality of the incoming water fluctuates greatly or the pollutant concentration is high, the process can maintain normal operation, so the operation management is also simple.
