▎ 摘　　要

NOVELTY - The device has an inlet barometer (2) that is arranged on a pipeline. A syringe (4) is connected to a syringe pump (3). The injection rate of the syringe is controlled by the syringe pump. The outlet of the syringe is connected to a gas-liquid three-way valve (7) through a sealing rubber tube (6). A syringe lock valve (5) is provided at the outlet of the syringe. An inlet of a quartz tube (8) is in communication with the gas-liquid three-way valve. The quartz tube is externally provided with radio frequency plasma generating source system (9) and a heating system (10). A sail-shaped foam nickel substrate (12) is placed in the reaction section of the quartz tube. The outlet of the quartz tube is connected to a vacuum pump (15) through a line, and an outlet barometer (13) is placed on the pipeline. USE - Device for cooperatively treating organic waste liquid and preparing graphene by using low-temperature plasma technology. ADVANTAGE - The process can be simplified, and treatment efficiency can be improved. The wide application range, flexible adjustability and high product value can be ensured. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for cooperatively treating organic waste liquid and preparing graphene by using low-temperature plasma technology. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the device for cooperatively treating organic waste liquid and preparing graphene by using low-temperature plasma technology.
