DETAILED DESCRIPTION - Graphene-based water treatment device comprises a reactor unit used for sewage treatment. The reactor unit includes a reactor, a cover plate, a N removable cards (n is an integer greater than 3), a water inlet pipe, a water pipe, a filter element, a micro pressure sensor, a control box and a direct current power supply. The reactor of the reactor unit is made of polyethylene plate, has a certain volume, with packing. The cover plate is located on the reactor. The cover plate and the reactor connection position symmetrically arranged with the micro pressure sensor. The movable board is arranged on the slot of the cover plate at equal intervals. The movable insert board is provided with a nano-composite metal oxide electrode product. The movable plug plate and the cover plate are connected with the direct current power source by wire. The graphite electrode is respectively attached to the wall on both sides of the reactor and connected with the direct current power supply wire. The reactor is respectively connected with a water outlet pipe and a water inlet pipe. The filter box is located between the outlet pipe and the reactor. The control box controls the switch of the water inlet valve and the switch of the direct current power source, and uploads the measured water quantity data to the computer. The computer according to the amount of water, power-on time and decontamination effect of printing reports. An INDEPENDENT CLAIM is also included for manufacturing graphene-based water treatment device comprising the nanometer synthetic metal oxide electrode product is based on graphene synthesis to obtain single layer metal oxide, which comprises pretreating, synthesizing monolayer iron oxide and making single layer iron oxide electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the graphene-based water treatment device.
