NOVELTY - This utility new type claims a filter one, comprise a main body, a filter layer, a filter layer fill the inner of the device body, a device main body set with a water inlet and a water outlet, a filter material in a filter material of surface layer is covered the graphene thin film layer. This utility new type through for filter material in filter layer is covered with a layer of graphene film, graphene a efficient adsorbent, a valid removal of a substance in water, and for water in a colloid, iron, organic matter, pesticide, manganese, bacteria, virus and so on is a pollutant removing effect. The filter speed is fast, also has filter precision high, capacity is large, a widely used for each a process water, domestic water, circulation with preprocessing field of water and waste water.
