Human activities, particularly agriculture and urbanization, have led to increased nitrogen and phosphorus discharge to inland water systems. This condition leads nutrient enrichment which causes eutrophication. Eutrophication can profoundly alter the structure and function of aquatic ecosystems, potentially endangering human health, biodiversity and ecosystem sustainability. Moreover, phosphorus which is vital for life and fertilizer industry will be exhausted shortly in the near future and become a major challenge for the global society. Therefore, both nitrogen and phosphorus in wastewater...
