▎ 摘  要

NOVELTY - The corrosion-resistant sewage treatment membrane (100) has a base layer (10) which is polyvinylidene fluoride material. An anti-impact layer (20) is provided which is a quartz sand layer. A filter layer (30) is a non-woven fabric layer. An adsorption layer (40) is made of carbon material. A corrosion-resistant layer (50) is made of PTFE. The carbon material of the adsorption layer is activated carbon, graphene or carbon nanotubes. The quartz sand layer is reinforced by a stainless steel wire mesh. USE - Corrosion-resistant sewage treatment membrane used in sewage treatment membrane filtration and separation device (claimed). ADVANTAGE - The impact resistance of the sewage is reduced by the reinforced anti-impact layer. The sewage purification degree is made high, after the strong adsorption layer is adsorbed. The use of PTFE as the wear-resistant layer and corrosion-resistant layer allows the sewage treatment membrane to greatly increase the corrosion resistance of the sewage treatment membrane, so that the service life of the membrane is extended. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the corrosion-resistant sewage treatment membrane.
