Rotary forward permeable membrane sewage treatment device

The invention discloses a rotary forward permeable membrane sewage treatment device. The device comprises a sewage treatment pool, a hollow rotary shaft, a forward permeable membrane assembly arrangedon the hollow rotary shaft and a driving mechanism which is in driving connection with the hollow rotary shaft; the driving mechanism drives the forward permeable membrane assembly to immersedly or semi-immersedly rotate in the sewage treatment pool through the hollow rotary shaft; the hollow rotary shaft is internally partitioned by a partition plate into a first cavity and a second cavity; an inlet of the first cavity is communicated with a seawater inlet pipe; an outlet of the first cavity is communicated with an inlet of the forward permeable membrane assembly; an outlet of the forward permeable membrane assembly is communicated with an inlet of the second cavity; an outlet of the second cavity is communicated with a seawater outlet pipe. According to the rotary forward permeable membrane sewage treatment dev
