MBR Integrated Wastewater Treatment Equipment Chongqing Wolik Environmental Protection Equipment Co., Ltd.
MBR integrated water treatment is a highly efficient new sewage treatment process (that is, MRB membrane life reactor) that uses a combination of hollow fiber membrane high-efficiency membrane separation technology and traditional activated sludge process to treat a variety of organic wastewater. Small area, stable treated water quality, good effluent water quality, simple maintenance and management.
1. It can efficiently perform solid-liquid separation, separating suspended matter, colloidal matter, and microbial flora lost in biological units from purified water. The separation process is simple, the floor area is small, and the quality of the effluent is good. Generally, it can be reused without third-level treatment.
2. The biomass in the biological treatment unit can be maintained at a high concentration and the volume load can be greatly improved. At the same time, the efficiency of membrane separation can greatly reduce the hydraulic retention time of the treatment unit, and the footprint of the bioreactor is correspondingly reduced.
3. As it can prevent the loss of various microbial flora, it is conducive to the growth of slow-growing bacteria (nitrobacteria, etc.), so that various metabolic processes in the system proceed smoothly.
4. Make the residence time of some large molecules difficult to degrade organic matter longer, which is conducive to their decomposition.
Membrane treatment technology is the same as other filtration and separation technologies. During long-term operation, the membrane is easily blocked as a filter medium, and the water production of the membrane gradually decreases with the running time. Effective backwashing and chemical cleaning can reduce the membrane flux. Decrease and maintain the effective service life of the MBR system.
MBR technology is applied in urban sewage treatment. Due to its simple process and convenient operation, it can realize fully automatic operation management.
MBR integrated water treatment equipment has a high removal rate of pollutants, strong resistance to sludge expansion, stable and reliable effluent quality, and no suspended solids in the effluent.
Membrane bioreactor achieves complete separation of reactor sludge age STR and hydraulic retention time HRT, greatly simplifying design and operation
The membrane's mechanical interception function prevents the loss of microorganisms and maintains a high sludge concentration in the bioreactor, which can increase the volume load and reduce the sludge load, and the MBR process eliminates the secondary sedimentation tank, greatly reducing the area
Due to the long SRT, the bioreactor also functions as a "sludge nitrification tank", thereby significantly reducing sludge production, low residual sludge production, and low sludge treatment costs.
The SRT is prolonged due to the membrane's interception effect, creating microorganisms that are conducive to slow proliferation. For example, the environment in which nitrobacteria grow can improve the nitrification capacity of the system, and at the same time, it is beneficial to improve the efficiency of the treatment of refractory macromolecular organic compounds and promote their complete decomposition.
The activated sludge of the MBR aeration tank is not lost due to the production of water. During the operation, the activated sludge will change due to the change in the concentration of entering organic matter, and reach a kind of dynamic balance, which makes the system's effluent stable and resistant to shock loads specialty
The large hydraulic cycle leads to uniform mixing of sewage, so that the activated sludge has good dispersibility and greatly increases the specific surface area of the activated sludge. The high dispersion of activated sludge in MBR system is another reason to improve the effect of water treatment. This is difficult to compare with the common biochemical water treatment technology to form larger bacterial micelles.
The membrane-bioreactor is easy to integrate, easy to realize automatic control, and convenient to operate and manage.
