Abstract
Provided is a method for reducing risks of composite pollutants in sewage, and belongs to the technical field of sewage treatment. The method includes the following steps: S1, measuring the concentration of dissolved organic carbon and the total concentration of composite pollutants in sewage; S2, measuring the proportion P of dissolved organic matter molecules with a modified aromaticity index ≥0.5 in sewage; S3, selecting a corresponding dual-media adsorption column filling scheme based on the ratio of the concentration of dissolved organic carbon to the total concentration of composite pollutants and the P. The method can upgrade the existing activated carbon adsorption process in situ, effectively reduce risks of composite pollutants in sewage, and effectively ensure the effluent safety of sewage treatment plants.
