Description
Résumé:This study takes the Nanfei River as an example, using a hydrodynamic and water quality model based on MIKE11 to predict the effect of graphene photocatalysis on urban rivers. The effect of water quality improvement in the Nanfei River was simulated under three different scenarios (treatment plant upgrade, use of graphene photocatalytic oxidation technology, and a combination of both), and the results showed that implementing a graphene photocatalytic network could significantly improve water quality. The improvement of sewage treatment plants can also improve the water quality to a certain extent, improving the sewage treatment plants alone is insufficient. The combination of graphene photocatalytic oxidation technology with methods to improve wastewater treatment plants produced the best improvement in water quality. The required water quality was achieved, as the total phosphorus content throughout the year was below the limit, and the ammonia nitrogen standard was met 95.89% of the time in the State-controlled section (Shikou section). Therefore, this study provides a new, feasible method for treating the water of polluted rivers
