The sewage treatment equipment adopts Membrane Bioreactor (MBR) technology, which is a new process that combines biological treatment technology and membrane separation technology. It replaces the two sinking pools in the traditional process. It can efficiently separate solid-liquid and obtain stable reclaimed water for direct use. It can also maintain a high concentration of microorganisms in the biological pool, the remaining sludge in the process is small, the ammonia nitrogen is very effectively removed, the suspension and turbidity of the effluent are close to zero, and the bacteria and viruses are greatly removed from the effluent, and the energy consumption is low, and the floor area is small.
