NOVELTY - The utility model claims a graphene sewage treatment device, comprising a main body, a first water storage chamber, a second water storage chamber and a filter layer; the first water storage chamber is welded on the outer wall of one side of the main body; the second water storage chamber is welded on the outer wall of one side of the main body; the first water storage chamber and the second water storage chamber are separated by the filter layer; the outer wall of one side of the second water storage chamber is fixed with a second sewage pump through a bolt; the top outer wall of the second sewage pump is connected with a second water outlet pipe through screw thread; one end of the second water outlet pipe is connected with one side outer wall of the first water storage chamber through screw thread; the outer wall of one side of the second water storage chamber is provided with a water outlet hole. The utility model is provided with a first water storage chamber, a second water storage chamber and a filter layer, which can make the pre-treated sewage enter into the first water storage chamber, then through the filter layer, sewage into the second water storage chamber, and then discharged by the water outlet hole; when the sewage passes through the filter layer, the porous ceramic (GDPC) modified by graphene absorbs the heavy metal ion in the sewage, It reaches the good processing effect.
