Embodiment 1
[0045] The graphite olefum fluid during production of oxidation reduction methods was collected. The graphene content in the graphene gas is 2-8%.
[0046] The graphite olefin obtained in the above step 1 is precisely filtered, (80 mesh), after the sharp substance in the filter solution, enter the feed buffer can, conveyed to the pressurized pump to increase pressure to 0.3 MPa After entering the ceramic membrane module, the ceramic membrane is deacive, and the ceramic membrane assembly is measured, and the temperature of the ceramic membrane degenerate is 20-32 ° C, and when the pH of the tank is 6-7, the ceramic membrane concentrate is obtained. Ceramic membrane dialysate.
[0047] The pH of the ceramic membrane concentrate obtained above was 6-7, and the resulting ceramic membrane concentrate further distilled dried. According to 80 tons of graphite per day, 800 tons of water per day, saving time of running time for 16 hours, and converted costs about 0.6 million yuan.

Embodiment 2
[0050] The graphite olefum fluid during production of oxidation reduction methods was collected. The graphene content in the graphene gas is 5-8%.
[0051] The graphite olefum liquid obtained in the above step (190 mesh), after the sharp substance in the filter solution, enter the feed buffer can, transported to the booster pump to increase the pressure to 0.4 MPa after entering The ceramic membrane module is concentrated in ceramic membrane while measuring the amount of water in the ceramic membrane module, the temperature of the ceramic membrane degenerate is 25-32 ° C, and when the pH of the tank is 6-7, the ceramic membrane concentrate and ceramic film are obtained. dialysate.
[0052]The pH of the ceramic membrane concentrate obtained above is 6-7, and the resulting ceramic film concentrate further distilled dry, according to 70 tons of graphene liquid per day, saving 700-1000 tons per day, saving time of operation 14h, converting a cost About 0.55 million yuan.

Embodiment 3
[0055] The graphite olefum fluid during production of oxidation reduction methods was collected. The graphene content in the graphene fluid is 4-8%.
[0056] The graphite olefum obtained in the above step is precisely filtered (200 mesh). After the sharp substance in the filter solution, the feed buffer can be transferred to the pressurized pump to boost to 0.4 MPa. The ceramic membrane module is reduced by ceramic membrane, and the ceramic membrane assembly is measured, and the temperature of the ceramic membrane degenerate is 22-30 ° C, and when the pH of the tank is 6-7, the ceramic membrane concentrate and ceramic film are obtained. dialysate.
[0057] The pH of the ceramic membrane concentrate obtained above is 6-7, and the resulting ceramic film concentrate further distilled dry, according to 100 tons of graphite liquid group per day, saving water 1000-1200 tons per day, saving running time 18h, converting a cost About 0.8 million yuan.
