Compact Municipal Sewage Wastewater Plant For Industrial And Municipal Sewage
Product Description
In the field of sewage treatment and water reuse, MBR, also known as Membrane Bio-Reactor (Membrane Bio-Reactor), is a new type of water treatment technology that combines a membrane separation unit and a biological treatment unit. According to the structure of the membrane, it can be divided into flat membrane, tubular membrane and hollow fiber membrane. According to the membrane pore size, it can be divided into microfiltration membrane, ultrafiltration membrane, nanofiltration membrane, and reverse osmosis membrane.
Process composition
Membrane-bioreactor is mainly composed of two parts: membrane separation module and bioreactor.
① Aeration Membrane Bioreactor (AMBR);
② Extractive membrane-bioreactor (ExtractiveMembrane Bioreactor, EMBR);
③ Solid/Liquid Separation Membrane Bioreactor (Solid/Liquid Separation Membrane Bioreactor, SLSMBR, referred to as MBR).
Process characteristics
Compared with many traditional biological water treatment processes,MBR has the following main advantages
1. High quality and stable effluent water quality Due to the efficient separation of membranes, the separation effect is much better than that of traditional sedimentation tanks, 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 domestic miscellaneous water quality standards issued by the Ministry of Construction (CJ25.1-89), it can be directly reused as non-potable municipal miscellaneous water.
2. Less surplus sludge output The process can be operated under high volume load and low sludge load, and the remaining sludge output is low (theoretically, zero sludge discharge can be achieved), which reduces the cost of sludge treatment.
3. Small footprint, not restricted by setting occasions The bioreactor can maintain a high concentration of microorganisms, the processing device has a high volume load, and the floor space is greatly saved; the process is simple, the structure is compact, and the floor space is saved. It is not restricted by the installation location, and is suitable for any occasion. It is ground, semi-underground and underground.
4. It can remove ammonia nitrogen and refractory organic matter Since the microorganisms are completely trapped in the bioreactor, it is beneficial to the trapped growth of slow-proliferating microorganisms such as nitrifying bacteria, and the nitrification efficiency of the system is improved. At the same time, it can increase the hydraulic residence time of some refractory organics in the system, which is beneficial to improve the degradation efficiency of refractory organics.
