    Wastewater Treatment New film - bioreactor (MBR) technology

    New film - bioreactor (MBR) technology

    Membrane bioreactor (Membrane Bio-Reactor, referred to as the MBR), is a combination of membrane separation and biological treatment, a new, efficient wastewater treatment technology, it is the separation of membrane technology in the engineering applied to the aerobic activated sludgethe mud treatment system to replace the conventional biological treatment technology in the secondary sedimentation tank and sand filter membrane.
    The MBR is the integration of biological treatment and membrane separation technology, water quality is good and stable area of
    province, less sludge production, stable operation and easy management of this century, the most promising high-tech water treatment technology.

    The Company's R & D results: new high efficiency low energy consumption the MBR;
    The mixture of regulation and membrane fouling online control technology integrated membrane fouling control mode;
    Urban sewage MBR strengthen the nitrogen and phosphorus removal, anaerobic pretreatment - MBR, the MRB reverse osmosis (RO), a variety of combinations of new technology; the MBR modular and standardized design methods, a number of technical
    Technological features:
    (1) good water quality, high stability of the membrane transition water makes the bio-concentration is much higher than conventional activated sludge membrane bioreactor, greatly enhancing the biodegradability and resistance to shock loading capability. Sludge retention time is longer, which embarrassed the degradation of organic decomposition bacteria and slow nitrification monocytogenes proliferation of microorganisms can be breeding enrichment reactor, especially for the removal of refractory organics and ammonia can achieve the desired effect. On the other hand, the membrane bioreactor membrane separation on the rejection of organic macromolecules smaller than the membrane pore size, to ensure that the filter effluent sterilization, to remove suspended solids and reduce the BOD is very stable.
    (2) covers an area of less membrane bioreactor can maintain a high sludge concentration, usually MLSS is 8 to 20g / L, 2.5 to 5 times of the conventional biological treatment, the system eliminates the need for secondary settling tank and sludge return equipment, which covers an area of the province.
    (3) membrane bioreactor operation and maintenance simple membrane separation unit process is simple, the water and run from the sludge and mud expansion factors, operation and maintenance simple and convenient, and easy to implement automatic control and management.
    (4) low-cost system of membrane bioreactor sludge at the water sludge concentration, sludge age long, which means that the sludge less sludge production volume accounted for only 30% of the traditional process, this follow-up of sludge treatment is extremely favorable.
    (5) the MBR the aeration tank of activated sludge due to water production loss during operation, activated sludge into the changes in the concentration of organic matter and reach a dynamic equilibrium, which makes the system water stability and resistance to impact load characteristics;
    (6) hydraulic cycle led to the uniform mixing of the sewage, thus making the activated sludge dispersion, greatly improving the specific surface area of activated sludge. Activated sludge in the MBR system is highly decentralized is another reason to improve the water treatment effect. This is a common biochemical method water treatment technology form larger zoogloea to be compared;
    (7), the complete separation of the membrane bioreactor reactor SRT STR and hydraulic retention time HRT, design, operation greatly simplified;
    (8) the entire process of automatic intelligent design, without human duty, simple operation, safe and reliable.
    Applications:
    Widely used in living quarters, guest houses, hotels, resorts, schools, office buildings, and other decentralized user's daily life sewage treatment, reuse and beer, leather, food, chemical and other organic wastewater treatment industry. Water production of the membrane bioreactor is commonly used for irrigation, washing, sanitation, landscaping and other non-potable functions.
