| 摘 要： | 以典型的致嗅物质二甲基异茨醇(2-MIB)为代表,考察了臭氧氧化工艺去除水体嗅味的效能.试验结果表明:臭氧投量为1.5 mg/L时,蒸馏水和自来水中2-MIB的氧化降解率分别为57.3%和54.2%.水中臭氧浓度和pH值的升高可以明显提高工艺对2-MIB的去除率,臭氧投量从1.0 mg/L提高至2.0 mg/L后,2-MIB的去除率由43.9%上升至72.8%;当溶液分别由弱酸性(pH=4.0)升高至中性偏酸(pH=6.5)以及由中性偏碱(pH=7.5)升高至弱碱性(pH=9.0)时,2-MIB的去除率分别提高了24.9和21.8个百分点.水中腐殖酸的浓度不同时对反应体系的影响不同,促进与抑制作用并存.

| Abstract: | Experiments were conducted to investigate the efficiency of ozonation process into degrading 2-Methylisoborneol(2-MIB),which was a typical taste and odor causing compound.Results showed that the 2-MIB removal efficiency in distilled and tap water were 57.3% and 54.2% respectively with an ozone dosage of 1.5 mg/L.A higher ozone concentration and higher pH in the water could increase the removal efficiency of 2-MIB,augment from 43.9% to 72.8% was obtained when the concentration of ozone increased from 1.0 mg/... |
