Mbr membrane is a highly effective integration of membrane separation technology and microbial solutions. Its origin is to replace the secondary sedimentation tank in the biological aerated filter with membrane separation technology to carry out solid-liquid separation. This kind of processing technology not only reasonably achieves the goal of sludge separation, but also has the advantages of three-level wastewater treatment that cannot be compared with traditional handicrafts:

1. The solid-liquid separation is carried out efficiently, and the actual effect of its separation is far better than that of the traditional grit chamber. The water body of the effluent is excellent, the suspended solids and turbidity of the effluent are close to zero, and the mbr membrane can be reused immediately, completing the recycling of wastewater.

2. The high interception effect of mbr membrane enables microbial strains to be completely trapped in the membrane bioreactor, completing the complete separation of the hydraulic power generation retention time (HRT) and sludge age (SRT) of the tubular reactor, and the operation is flexible and stable.

3. Because the mbr membrane combines the hydrolysis acidification tank and the secondary sedimentation tank of traditional wastewater treatment into one, and replaces all the processing equipment of the three-level solution, it can greatly reduce the land occupation and save the investment in civil engineering projects.

4. It is conducive to the interception and breeding of nitrifying bacteria, and the system software has high efficiency in nitrification reaction. According to the change of operation method, it can also have the function of ammonia and phosphorus removal.

5. Because the mud age can be very long, the dissolution efficiency of insoluble organic compounds can be further improved.

6. Mbr membrane operates under high capacity load, low sludge concentration and long sludge age, and the remaining sludge production is extremely low, because the sludge age can be infinitely long, theoretically, zero sludge discharge can be completed.

7. The system software completes PLC control, and the actual operation management method is convenient.
