MBBR(Moving Bed Biofilm Reactor)
This method adds a certain amount of suspended carriers into the reactor to increase the biomass and biological species in the reactor, thereby improving the treatment efficiency of the reactor. Since the density of the filler is close to water, it is completely mixed with water during aeration, and the environment for microbial growth is three phases of gas, liquid and solid. The collision and shearing of the carrier in the water make the air bubbles smaller and increase the utilization rate of oxygen. In addition, each carrier has different biological species inside and outside, with some anaerobic or facultative bacteria growing inside and aerobic bacteria growing outside. In this way, each carrier is a microreactor, allowing nitrification and denitrification reactions to coexist. , thus improving the processing effect.
MBBR The process combines the advantages of traditional fluidized bed and biological contact oxidation methods. It is a new and efficient sewage treatment method. It relies on the aeration in the aeration tank and the lifting effect of water flow to keep the carrier in a fluidized state, thereby forming suspended growth. The activated sludge and attached growing biofilm make the moving bed biofilm use the entire reactor space, giving full play to the advantages of both attached phase and suspended phase organisms, so that they can maximize their strengths, avoid weaknesses, and complement each other. Different from previous fillers, suspended fillers can frequently come into contact with sewage and are therefore called "mobile biofilms."
Moving bed biofilm reactor process ( MBBR) The key to the technology lies in the research and development of biological fillers that have a specific gravity close to water and are easy to move freely with water under slight stirring. It has a large effective specific surface area and is suitable for the adsorption and growth of microorganisms. It has strong applicability and a wide range of applications. It can be used for organic matter. It can also be used for nitrogen and phosphorus removal; it can be used not only in new sewage treatment plants, but also in the process transformation and upgrading of existing sewage treatment plants.
The equipment has a service life of30YearAbove, the anti-corrosion standards and levels of the equipment box are: the internal liquid immersion area (area where water may be immersed) is three layers of modified epoxy thick build paint, and the external non-liquid immersion area (area where water cannot be immersed) is one layer Epoxy zinc-rich paint (primer) +Two coats of epoxy paint EX(middle level )+ One coat of polyurethane topcoat 3010 (topcoat).This project integratesSewage treatment equipmentPlaced outdoors, the main reactions of the equipment are divided into pre-denitrification zone, anaerobic zone, anoxic zone, aerobic zone and sedimentation zone.
MBBR The process has stable performance under high load conditions and can be used in multiple stages to treat sewage. mbbr Experimental demonstration of process MBBR Based on the performance and characteristics of the start-up and operation of the technology in low-load domestic sewage treatment, it was found that the closed-circuit circulation method starts slightly slower than the sludge discharge and membrane method, but the treatment effect in the early stage of operation is better than the latter.If 3 can be MBBR Connected and used to treat meat processing wastewater, diyi reactor COD Loads up to 10 kg/m3,HRT about 4 h,TC0D Removal rate 50%-75% {The total of the second and third reactors HRT is 4 ~13h,TCOD The removal rate is 75%, SCOD Removal rate 70% ~88%,The organic matter removal rate has a linear relationship with the organic load.
two, MBBR Advantages of sewage treatment systems
(1)Aerobic, anoxic and anaerobic conditions are formed on the filler, and nitrification and denitrification are carried out at the same time, which has a good effect on the removal of ammonia nitrogen.
(2)The high sludge concentration improves the treatment efficiency of organic matter and has strong impact load resistance.
(3)There is no need to install a packing bracket in the aeration tank, making it easy to maintain and manage.
