NOVELTY - The utility model claims a graphene stack-based filler for sewage processing biological membrane, it is composed of six parts, which are respectively a graphene stack (1), an aerobic layer (2), facultative aerobic layer (3), an anaerobic layer (4), an attachment layer (5). flowing layer (6), the graphene layer is middle layer, graphene stack formed by surface van der Waals adsorption aerobic amine type of aerobic layer, then through the adhesion surface of the aerobic layer adsorption facultative aerobic, facultative aerobic layer through adhesion and anaerobic layer adsorption. anaerobic layer surface to form a highly hydrophilic surface layer attached layer, firstly absorbed in organic thing sewage of adhering layer, when the attached contaminant reaches a certain thickness, flow through scouring the biological membrane updating. The utility model is to remove sewage nitrogen and phosphorus element and so solve the problem of breeding water body biological film, compared with common filler is featured with simple preparation, low cost, easy recycling, environment-friendly application and theory, it has important value.
