▎ 摘 要
NOVELTY - Flocculating aid comprises 75-85 pts. wt. gum Arabic graphene oxide microcapsule and 15-25 pts. wt. dispersing agent. The gum Arabic graphene oxide microcapsule comprises a core material and a wall material enclosing the core material. The mass ratio of wall material and core material is 0.5:1-2:1. The core material is graphene oxide and the wall material is gum Arabic. USE - The flocculating aid is useful in sewage treatment (claimed). ADVANTAGE - The flocculating aid improves flocculation efficiency, purification rate of flocculating unit, and reduces the dosage of flocculating aid. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the flocculating aid involving (i) preparing gum Arabic oxide graphene microcapsule and (ii) mixing gum Arabic oxide graphene microcapsule with dispersant.
