Flat-sheet membrane reactor for laboratory

The invention discloses a flat-sheet membrane reactor for a laboratory and belongs to the technical field of water treatment adopting membrane bioreactors and membrane chemical reactors. The flat-sheet membrane reactor is used for evaluating filtering performance of an ultrafiltration membrane, is prepared from transparent organic glass and stainless steel screw rods and comprises a detachable casing and a flat-sheet membrane assembly, wherein the realization mode of the detachable casing is that a left plate and a right plate after being drilled on the thickness surfaces are connected with a front plate and a back plate through the screw rods in a penetrating manner, two ends are fastened by butterfly nuts, and joint parts are sealed by foamed rubber plates; the membrane assembly mainly comprises concave cover plates, convex guide plates and a pumping central cavity plate which are connected through nylon screws in a penetrating manner, joint parts of the concave cover plates and the pumping central cavity plate are sealed by foamed silica gel, the convex guide plates are wedged into the concave cover plates to clamp a membrane, and clear water reaches a central cavity through the membrane and guide plate round holes during pumping filtration and flows out through a water outlet round pipe above the central cavity. The casing of the reactor has good sealing performance, the left plate and the right plate can be detached and are convenient to clean, and the volume of the reactor can be flexibly extended.
