Technical development of hospital wastewater treatment

Abstract

The source and composition of hospital wastewater are complex，including pathogenic microorganisms，chemical drugs and metabolites，heavy metals，contrast agents，resistance genes，etc. When it in a special period of repeated outbreaks of Corona Virus Disease 2019（COVID-19）， the number of patients in the hospital is increasing rapidly，and the corresponding consumed therapeutic drugs，disinfectants，pathogenic microorganisms are increasing significantly. If the hospital wastewater is not effectively treated by cutting off the ways of pathogenic microorganisms and toxic and harmful substances into the environment，the risk caused by effluent would increase rapidly. This paper analyzes the current situation and problems of domestic hospital wastewater treatment，and clarifies the conventional and frontiers technologies on effluent treatment based on the main components and characteristics of hospital wastewater，and combines with the existing policies and technical specifications on hospital wastewater treatment. Finally，some relative countermeasures and constructive suggestions were proposed to provide some technical reference for the hospital wastewater treatment in China.
