Differential comparison of degradation efficiencies in urban environmental waters and effluents and with and without nanoparticles

Abstract

DOM is an important component of water bodies and provides unimaginable vitality to the entire water body. This paper employed a filter configuration method to extract dissolved organic matter and sewage. In the control group, nanoparticles are added to set up a control group. The degradation efficiency of urban water bodies and sewage and their degradation efficiency in the presence or absence of nanoparticles was compared using a UV spectrophotometer and a photochemical reaction meter. By analyzing the degradation efficiency of DOC, we observed that the degradation efficiency of urban water is much higher than that of wastewater, and nanoparticles can increase the reaction rate. This effect is particularly pronounced in pond water, which can provide a reference for the standard of wastewater discharge and urban water management.
