Vortex flow membrane bioreactor with low energy consumption

The utility model relates to a vortex flow membrane bioreactor with low energy consumption, relating to physical treatment and biological treatment on waste water or sewage. The vortex flow membrane bioreactor with low energy consumption disclosed by the utility model is composed of a circulation water tank, a peristalsis reciprocating type circulation water pump, a membrane component, a membrane bracket, a bioreactor, a control valve, a communication pipe, a filter net, a pressure gauge and a water outlet. The vortex flow membrane bioreactor with low energy consumption disclosed by the utility model has the characteristics in the operation process that water flow is in a vortex flow state under low Reynolds number in the membrane component, so that high energy consumption caused by high flow speed of the water flow under high Reynolds number in the membrane component in a traditional membrane bioreactor is overcome; artificial aeration is unnecessary; microorganisms are directly in contact with air; high ene
