Sonochemical Decomposition of Humic Substances in Wastewater Effluent

摘要

The sonochemical process is applied as a treatment method to investigate its effect on the TOC removal of humic substances. The extent of TOC removal was proportional to factors such as ultrasonic energy intensity and hydrogen peroxide concentration while increasing of total carbonate, pH, and temperature decreased the extent of TOC removal of humic substances. The Langmuir-Hinshelwood model provided a good fit of the experimental data. Experimental results also showed the factor such as dose of hydrogen peroxide affected the formation of disinfection by-products. Chloroform and dichlorobromomethane were formed as major THMs during chlorination.
