UV/H2O2高级氧化工艺对去除饮用水中2-MIB和GSM效果的分析
Analysis of Effect of UV/H2O2 AOP on 2-MIB and GSM Removal in Drinking Water
摘要
Abstract
[Objective]Aiming at the problem that typical odor and taste substances such as 2-methylisoborneol(2-MIB)and geosmin(GSM)in drinking water are difficult to effectively control,[Methods]the pilot test of ultraviolet/hydrogen peroxide(H2O2)advanced oxidation was carried out in this paper.[Results]It was found that the initial concentration of 2-MIB and GSM,the dosage of H2O2 and the water intake had important effects on the removal rate of 2-MIB and GSM.Under the experimental conditions of this study,when the dosage of H2O2 increased from 0 to 12 mg/L,the removal rate of 2-MIB increased from 7.54％to 87.24％,the removal rate of GSM increased from 22.77％to 89.66％.When the water intake was halved(ultraviolet dosage doubled)and the H2O2 dosage increased from 0 to 12 mg/L,the removal rate of 2-MIB increased from 7.49％to 92.86％and the removal rate of GSM increased from 17.13％to 90.98％.[Conclusion]The study shows that the presence of H2O2 can significantly improve the removal rate of odor and taste substances,and hydroxyl radical plays a key role in removal process of odor and taste substances,and H2O2 can generate more hydroxyl radicals under ultraviolet irradiation.This study can provide powerful technical support for removal of odor and taste substances in drinking water.关键词
