摘要

Abstract

[Objective]To address the odor and taste problems in drinking water,pilot tests are conducted at water treatment plant A and B to investigate the removal efficiencies of typical odorous and taste substances such as 2-methylisoborneol(2-MIB)and geosmin(GSM)by ultraviolet/hydrogen peroxide(UV/H2O2)advanced oxidation process.[Methods]This paper conducted a pilot test verification of UV/H2O2 advanced oxidation process,and found that the initial concentrations of 2-MIB and GSM,the dosage of H2O2,the dosage of UV radiation,and the coupling of biological activated carbon(BAC)all had significant effects on the removal rates of 2-MIB and GSM.[Results]Under the experimental conditions of this study,the removal rate of 2-MIB was 87.24%when the dosage of hydrogen peroxide was 12 mg/L,and the removal rate of GSM was 91.36%;when the dosage of UV radiation was increased,the removal rates of 2-MIB and GSM increased to 94.79%and 95.90%,respectively.UV/H2O2 advanced oxidation process effluent met the water quality requirements of odorous and taste substances in the Standard for Drinking Water Quality(GB 5749-2022).[Conclusion]Presence of H2O2 can significantly improve the removal rate of odorous and taste substances,and the hydroxyl radical(·OH)plays a key role in the removal process of odorous and taste substances,and H2O2 can generate more·OH under UV irradiation.BAC can effectively quench the residual H2O2 and further remove the odorous and taste substances in water,optimizing the water quality.This study can provide powerful technical support for the removal of odorous and taste in drinking water.
