The sewage treatment equipment adopts Membrane Bioreactor (MBR) technology, which is a new equipment combining biological treatment technology and membrane separation technology, replacing the secondary sedimentation tank in the traditional process. It can efficiently separate solid and liquid and obtain stable water for direct use. It can also maintain a high concentration of microorganisms in the biological tank, the remaining sludge of the process is less, the ammonia nitrogen is very effectively removed, the suspended matter and turbidity of the effluent are close to zero, the bacteria and viruses in the effluent are greatly removed, the energy consumption is low, and the footprint is small. It can be installed in buried, semi-buried or ground type according to the site conditions.
