The utility model provides a tubular MBR (Membrane Bio-Reactor) which is not easy to block. The tubular MBR comprises a tubular reactor body, a biological reaction tank and a shelving frame for shelving the tubular reactor body, wherein a water inlet is formed in the top of the tubular reactor body, a water outlet pipe is arranged at the bottom, the biological reaction tank is located under the water outlet pipe of the tubular reactor body, a water inlet pipeline communicated with the water inlet is arranged in the biological reaction tank, and a submersible pump is arranged at the bottom of the water inlet pipeline; a shelving plate is arranged at the lower part of the tubular reactor body, a plurality of through holes are formed in the shelving plate, and an MBR flat sheet membrane is placed on the shelving plate. The water flow in the MBR membrane bioreactor and the MBR flat membrane are always in a relative motion state and are not easy to block, the contact time of sewage and airis prolonged by utilizing
