The invention discloses a method for preparing a plain-film filter membrane of a membrane bioreactor used in treatment of industrial sewage. The method comprises: dissolving polymer membrane material in solvent; adding with additive and evenly stirring; adding with pore-forming agent and evenly stirring so as to prepare casting solution; after filtering and vacuum defoamation of the casting solution, blade-coating the casting solution on polyester non-woven fabrics; and after being stood in air for a period of time, soaking the polyester non-woven fabrics in gel bath for gel curing, and preparing the plain-film filter membrane. The filter membrane prepared by the method simultaneously has the characteristics of strong tolerance, pollution resistance, high pure water flux, high rejection rate and the like. When the filter membrane is used to prepare MBR series membranes in 0.25, 1.0 and 1.5 square meters, the MBR series membranes can be used for industrial sewage treatment, and the effluent ...
