▎ 摘　　要

NOVELTY - Use of hydroxyethyl cellulose graphene flocculating agent in the sewage treatment, is claimed. The hydroxyethyl cellulose graphene flocculating agent comprises 70-90 pts. wt. hydroxyethyl cellulose graphene microcapsules and 10-30 pts. wt. dispersing agent. The hydroxyethyl cellulose graphene microcapsules comprise a core material and a wall material wrapping the core material. The mass ratio of wall material and core material is 0.6:1-1.5:1. The core material is graphene. The wall material is hydroxyethyl cellulose. USE - The hydroxyethyl cellulose graphene flocculating agent is useful for improving flocculation efficiency of flocculating agent in the sewage treatment (claimed). ADVANTAGE - The hydroxyethyl cellulose graphene flocculating agent can improve the flocculation efficiency and the purification rate of the unit flocculating agent, and maintain or reduce the dosage of the flocculating agent.
