▎ 摘　　要

NOVELTY - A hydroxyethyl cellulose oxidation graphene flocculating agent comprises 75-90 pts. wt. hydroxyethyl cellulose graphene oxide microcapsule and 10-25 pts. wt. dispersant. The hydroxyethyl cellulose graphene oxide microcapsule comprises core material and wall material for covering core material. The mass ratio of wall material and core material is 0.5:1-1.6:1. The core material is graphene oxide. The wall material is hydroxyethyl cellulose. USE - Hydroxyethyl cellulose oxidation graphene flocculating agent used in sewage treatment (claimed). ADVANTAGE - The agent maintains or decreases dosage, and improves flocculation efficiency and purification unit flocculating agent. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the hydroxyethyl cellulose oxidation graphene flocculating agent comprising mixing dispersant and hydroxyethyl cellulose graphene oxide microcapsule.
