MBR sewage treatment equipment

The utility model relates to the technical field of sewage treatment, in particular to MBR (membrane bioreactor) sewage treatment equipment which comprises a base, a primary filter tank is welded at the top of the base, a solid screening component is arranged above the primary filter tank, an adjusting tank is arranged on one side of the primary filter tank, a membrane tank is arranged on one side of the adjusting tank, and a water outlet is formed in the other side of the membrane tank. The regulating tank and the membrane tank are respectively and fixedly connected to the top of the base, and a collecting box is arranged at the top of the membrane tank. According to the improved MBR sewage treatment equipment, the purpose of vibrating the MBR membrane body below is achieved by utilizing the contact striking process of the eccentric wheel and the pressing block and the elastic structure of the first tension spring and the second tension spring, and impurities adsorbed on the surface of the MBR membrane body
