Study on the Color of Biochemical Tail Water by Coagulation Precipitation+Activated Carbon Adsorption Process
With the increase of industrial production capacity and the acceleration of people's pace of life,the discharge of industrial and domestic sewage is gradually increasing,which has a greater impact on the environment.Chromaticity is one of the important indicators for evaluating water pollution,and therefore has become an important research direction for sewage treatment.This article analyzes the formation and harm of chromaticity,briefly explains the current technical methods for chromaticity treatment,introduces the principles of coagulation precipitation and activated carbon adsorption,determines the optimal dosage of PAM,PAC,and activated carbon used in the coagulation precipitation+activated carbon adsorption process through experiments,and determines the optimal time for activated carbon adsorption,laying a theoretical foundation for the subsequent utilization of this process.
