The invention claims a sewage treatment process the process of the sewage treatment device and the membrane component and membrane biological reactor. in the sewage treatment process firstly enters the sewage inlet is installed with a large aperture filter membrane of membrane module (503) in the aeration section (502). to obtain active sludge in the aeration tank and controlling the oxygen transmission rate of the aeration section (502) to maintain enough oxygen. sewage inlet and activated sludge are mixed into the first mixed liquor. part of the first mixed solution after membrane filtering forming a permeate liquid and discharged from the reactor as the water outside the residual part is still treated as un-filtering active sludge suspended in the aeration section (502). the second portion of the first mixed solution is migration into the anaerobic area (515) to form a second mixed solution. the second mixed liquid will then return to the aeration section (502).
