▎ 摘　　要

NOVELTY - Preparing nanomaterials for sewage treatment, comprises (i) dispersing modified attapulgite into water, dispersing modified activated carbon in water to obtain a modified activated carbon solution, (ii) dispersing graphene oxide in water to obtain graphene oxide solution under stirring, introducing modified attapulgite solution and modified activated carbon solution, stirring until modified attapulgite and modified activated carbon are supported on the surface of graphene oxide, washing, nanomaterials for sewage treatment are obtained by drying. USE - The method is useful for preparing nanomaterials for sewage treatment. ADVANTAGE - The nano improves the adsorption effect and deodorization effect of heavy metal ion in the sewage. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a nano-material for sewage treatment prepared by the preparation method.
