Factors of treating wastewater with modified carbon and nitrogen materials

Abstract

Nowadays, environmental pollution, climate change and energy shortage have become widespread concerns in the world. With the rapid development of industrial production, more and more refractory organic matter enters the water environment.Traditional treatment methods have been unable to fully meet the requirements of wastewater treatment at the present stage. Studies in recent years have found that metal frame nanocomposites have a remarkable effect in the treatment of refractory wastewater. With the proposed goals of "carbon peak" and "carbon neutrality", lithium-ion batteries have been widely used in various fields of daily industrial production and life. The waste lithium-ion batteries have significant resource characteristics, and the valuable metal elements contained in them play an active role in the neighborhood of refractory wastewater treatment.In this paper, the recycled NCM material was prepared by the method of reusing the metal leaching solution of Ni, Co and Mn in waste batteries, which combined with the activation of persulfate to produce highly active sulfate free radicals, and realized the efficient degradation of pollutants in organic wastewater.
