Abstract

The invention relates to the technical field of sewage purification, in particular to a graphene sewage purification material and a preparation method thereof. The graphene sewage purification material is prepared by the following four formulas: 1, 10-20 parts of graphene powder, 2-10 parts of polyacrylamide and 60-80 parts of polypropylene pyrrolidone; 2, one of a 100-800-mesh mesh fabric, a polyester mesh fabric, an acrylic fabric, a polypropylene fabric, a spandex fabric and a nylon fabric; 3, one or more of polyurethane sponge, polyvinyl alcohol sponge and melamine sponge, 100-150 parts of absolute ethyl alcohol, 5-10 parts of tetraethoxysilane, 2-5 parts of ammonia water and 2-3 parts of deionized water; and 4, a PVA aqueous solution or cross-linked PVA hydrogel are prepared by usingone or more of boric acid, borax and glutaraldehyde as a cross-linking agent. According to the invention, the prepared graphene sewage purification device is convenient to use, can perform large-scale oil-water separation, does not need to perform any post-treatment on a filter screen after separation, improves the analysis efficiency, and is long in service life.

Description

technical field [0001] The invention relates to the technical field of sewage purification, in particular to a graphene sewage purification material and a preparation method thereof. Background technique [0002] Water pollution is water that reduces or loses the use value of water caused by harmful chemicals and pollutes the environment. Acids, alkalis, oxidants, and compounds such as copper, cadmium, mercury, and arsenic in sewage, organic poisons such as benzene, dichloroethane, and ethylene glycol, will kill aquatic organisms and affect drinking water sources and scenic spots. When the organic matter in the sewage is decomposed by microorganisms, the oxygen in the water is consumed, which affects the life of aquatic organisms. After the dissolved oxygen in the water is exhausted, the organic matter undergoes anaerobic decomposition, producing hydrogen sulfide, mercaptan and other unpleasant gases, which further deteriorates the water quality. Increasing water pollution ...
