▎ 摘　　要

NOVELTY - Method for purifying waste water based on graphene membrane, involves storing waste water in large-diameter transparent container, placing graphene membrane on surface of the waste water, illuminating the transparent container, and evaporating the waste water. The graphene membrane comprises 2-4 pts. wt. poly(N,N-dimethylaminoethyl methacrylate), 1-3 pts. wt. sodium alginate, and 9-12 parts of graphene. USE - The method is useful for purifying waste water (claimed). ADVANTAGE - The method saves energy and provides high purity distilled water.
