MBR membrane Analysis of advantages

Compared with traditional microbial wastewater treatment process, MBR membrane has the following key advantages:

1. The outlet water body is excellent and stable

Because of the separation efficiency of the membrane, the actual effect of separation is far better than that of the traditional grit chamber. The effluent is clear, the suspended solids and turbidity are close to zero, and the bacteria are largely removed. The effluent water is better than the water quality detection standard for daily miscellaneous tap water (CJ25.1-89) granted by the Ministry of Housing and Urban Rural Development, and can be immediately reused as miscellaneous tap water for non edible municipal projects.

At the same time, the membrane separation technology also enables microbial strains to be completely trapped in the membrane bioreactor, enabling the system software to maintain a high concentration of microbial strains, which not only improves the overall removal efficiency of the equipment for pollutants, but also ensures an excellent outlet water body, At the same time, the tubular reactor has a very good adaptability to various changes in the seepage load (water body and water flow). It can resist the impact load, and can stably obtain excellent water outlet.

2. Less production of remaining sludge

The process can operate under high capacity load and low sludge concentration, and the remaining sludge production is low (theoretically, zero sludge discharge can be completed), reducing sludge disposal costs.

3. Small area, not limited by the set place

Membrane bioreactor can maintain a high concentration of microbial species, solve the problem of high equipment capacity load, and greatly save land occupation;

Mbr membrane is simple in steps, compact in structure, and economical in land occupation. It will not be limited by the set site. It is suitable for all places and can be made into pavement type, semi basement type and underground type.

4. It can remove ammonia nitrogen and insoluble organic compounds

Because microbial strains are completely trapped in the membrane bioreactor, which is beneficial to the interception and growth of slow growing microbial strains such as nitrifying bacteria, the efficiency of nitrification reaction in the system software has been improved. At the same time, it can improve the retention time of some insoluble organic compounds in the system software for hydropower generation, which is conducive to improving the dissolution efficiency of insoluble organic compounds.

5. The practical operation and management method is convenient, and it is convenient to complete the automatic control system

This process has completed the complete separation of the retention time (HRT) of hydropower generation and the retention time (SRT) of sludge, making the operation more flexible and stable. It is a new technology application that is very easy to complete weaponization in wastewater treatment, and can complete the microcomputer automatic control system, thus making the actual operation management method more convenient.

6. It is convenient to carry out renovation from traditional process

Mbr membrane technology can be used as a deep control component of traditional wastewater treatment process, and has broad application prospects in industries such as deep solution of effluent from secondary sewage treatment stations in large cities (thus completing a lot of reuse of domestic sewage).
