NOVELTY - The utility model claims a cage-type combined graphene sponge biological filler for water treatment, relating to graphene sponge processing technology field, comprising a shell, one side of the middle position of the shell fixedly connected with with a driving motor, one side of the shell close to the driving motor is rotatably connected with a driving shaft, the bottom of the driving shaft fixedly connected with with a connecting rod, two ends of the connecting rod are connected with a graphene sponge ring, the middle position of the shell fixedly connected with with a baffle plate, the shell is provided with a baffle plate and a horizontal position fixedly connected with the processing box. when the driving motor drives the bottom of the driving shaft through the belt transmission mechanism to fix the graphene sponge ring fixedly connected by the connecting rod to rotate the graphene sponge ring absorbed with oil stain to the lower part, the driving motor drives the pressing rod to move downwards to drive the pressure rod to extrude the dirty oil on the graphene sponge ring by driving the inclined plate intermittently, so as to realize the kitchen sewage treatment device without changing the graphene sponge, still make the graphene sponge ensure the normal work.
