Study on the Purification Effect of Graphene Photocatalytic Materials on Polluted Water
In order to effectively improve the treatment effect of water pollution from the source,the advantages of graphene photocatalytic technology were utilized to compare and analyze the purification effects of graphene photocatalytic materials composed of graphene+polyethylene+nano TiO2+carbon fibers in different laying area ratios of 100%,70%,50%,and 30%.Compared with the blank group,there is not much difference in the removal efficiency of TN and NH3-N among different laying area ratios,but there is a significant advantage in COD removal and DO improvement.And the final purification effect order is:30%<50%<70%<100%,the optimal laying area ratio is 70%,and its COD removal rate exceeds the blank control group by 75.08%,indicating that this material can effectively treat water pollution.
