The invention discloses an MUCT-MBR (Modified University of Cape Town-membrane bioreactor) combination technique for sewage treatment, which comprises the following steps: inoculating a dominant strain to an anaerobic reactor, a first anoxic reactor, a second anoxic reactor and an aerobic reactor; injecting raw sewage into the anaerobic reactor through a water inlet pump, and stirring to carry out anaerobic phosphorus-release reaction on the raw sewage; sending the effluent mixed solution from the anaerobic reactor in the second step into the first anoxic reactor, and carrying out anoxic phosphorus-absorption reaction under stirring actions; sending the effluent mixed solution from the first anoxic reactor in the third step into the second anoxic reactor, and stirring to carry out anoxic phosphorus-absorption reaction and reduce nitrates in the sewage into nitrogen; and sending part of the mixed solution of the second anoxic reactor into the aerobic reactor, and sending the rest of the mixed solution to the a
