The invention relates to an MABR membrane material capable of fast biofilm culturing, a membrane module and a biochemical reactor containing the membrane module, the MABR membrane material comprises an inner layer of non-woven fabric and an outer layer of non-woven fabric, the inner layer of non-woven fabric plays a supporting role, the outer side face of the outer layer of non-woven fabric is coated with a nutrient layer, the nutrient layer comprises polyhydroxyalkanoate and sulfur powder, and the outer layer of non-woven fabric plays a supporting role. The method is used for providing nutrients for microorganisms in the initial biofilm formation stage. The membrane assembly comprises a plurality of membranes, each membrane is composed of two MABR membrane materials, ultrasonic spot welding is carried out on the outer sides of outer-layer non-woven fabrics of the two MABR membrane materials, so that the two MABR membrane materials form a plurality of vertical protruding parts, the interiors of the protruding
