MBR membrane Bioresponder It is a new type of useful sewage treatment process that combines the useful membrane separation skills with the traditional activated sludge process. It uses MBR flat membrane modules with a unique structure to place them in the aeration tank. The water after aerobic aeration and biological treatment is pumped out by the pump after filtering through the filter membrane. MBR sewage treatment is very different from the traditional sewage treatment method. The secondary sedimentation tank and tertiary treatment process in the traditional process are replaced by membrane separation equipment. Then excellent effluent is obtained, which solves the problem that the effluent quality of traditional environmental protection equipment for sewage treatment cannot meet the requirements of reclaimed water reuse.
MBR sewage treated water can be directly used as municipal water or further treated as various industrial water. Because the existence of MBR membrane has greatly promoted the ability of separating solid and liquid in the system, and then the water quality and volume load of MBR membrane bioreactor effluent have been greatly promoted. The water quality after membrane treatment is of high standard, and after disinfection, it finally constitutes superior reconstituted water with high water quality and biological stability, which can be directly used as the source of regeneration. Because of the filtration effect of the membrane, microorganisms are completely trapped in the MBR membrane bioreactor, completing the thorough separation of hydraulic retention time and activated sludge age, and eliminating the problem of sludge bulking in the traditional activated sludge process. MBR membrane bioreactor has the advantages of high pollutant removal power, strong nitrification ability, good nitrification, denitrification effect, stable effluent quality, low output value of remaining sludge, compact equipment, small floor area (only 1/3-1/2 of the traditional process), convenient incremental capacity expansion, high degree of automation, simple operation, etc. MBR membrane bioreactor module series has the advantages of compact structure, beautiful appearance, small floor area, low operating cost, stability and reliability, high degree of automation, convenient maintenance and operation, etc. The effluent quality of MBR sewage treatment is good, superior to the reclaimed water quality specification. With its unique MBR flat membrane technology, it overcomes many shortcomings of ordinary hollow fiber membrane and is an advanced sewage treatment product equipment in today's society. The series of membrane modules of MBR membrane bioreactor have now become a standardized series of MBR membrane products. Each module is composed of 50-150 standard flat membranes. It can also be planned independently according to the needs of users to meet their needs.
Compared with many traditional biological water treatment processes, MBR has the following primary interests:
1. The effluent quality is excellent and stable. Due to the effective separation effect of the membrane, the separation effect is far better than that of the traditional sedimentation tank. The treated effluent is extremely clear, suspended solids and turbidity are close to zero, bacteria and viruses are greatly removed, and the effluent quality is better than the quality specification for domestic miscellaneous water issued by the Ministry of Construction (CJ25.1-89), which can be directly reused as non drinking municipal miscellaneous water. At the same time, membrane separation also enables microorganisms to be completely intercepted in the bioreactor, enabling the system to maintain a high microbial concentration, which not only improves the overall removal power of the reaction equipment for pollutants, but also ensures excellent effluent quality. At the same time, the bioreactor has good adaptability to various changes in the influent load (water quality and quantity), and is resistant to impact loads, Stable and excellent effluent quality can be obtained.
2. Less output value of remaining sludge This process can operate under high volume load and low sludge load, and the output value of remaining sludge is low (theoretically, it can end zero sludge discharge), reducing the sludge treatment cost.
3. The land occupation is small, and the bioreactor can maintain a high concentration of microbial biomass without being constrained by the setting situation. The volume load of the treatment equipment is high, and the land occupation is large and saves money; The process flow is simple, the structure is compact, the floor area is saved, and it is not bound by the location. It is suitable for any occasion, and can be made into ground, semi underground and underground.
4. The ammonia nitrogen that can be removed and the refractory organics are intercepted in the bioreactor due to the fact that the microorganisms are intact, which is conducive to the interception and growth of slow growing microorganisms, such as nitrifying bacteria, and the nitrification power of the system can move forward. Together, it can increase the hydraulic retention time of some refractory organics in the system, which is conducive to the progress of the degradation power of refractory organics.
5. Convenient operation and treatment, easy to end automatic control This process ends the perfect difference between hydraulic retention time (HRT) and sludge retention time (SRT.
6. It is easy to transform from the traditional process. This process can be used as the advanced treatment unit of the traditional sewage treatment process, and has broad application prospects in the fields of advanced treatment of the effluent of the urban secondary sewage treatment plant (and then the end of the mass reuse of urban sewage).
