▎ 摘　　要

NOVELTY - Processing graphite/graphene oxide in production of waste liquid involves adding slaked lime into acid waste liquid to process, stirring, cooling, testing liquid for acidity-basicity to obtain slurry, subjecting slurry to solid-liquid separation and drying to obtain residue. USE - Method for processing graphite/graphene oxide in production of waste liquid. ADVANTAGE - The method enables to process graphite/graphene oxide in production of waste liquid that realizes industrial grade graphite oxide waste liquid low recycling cost and recycling of solid waste, reduces waste liquid treatment and cement production cost, and in eco-frindly and cost effective manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a cement, which comprises cement retarder and cement clinker.
