【摘要】 紫外/过氧化氢（UV/H₂O₂）和紫外/过硫酸盐（UV/PS）均可有效降解纯水体系中的2-甲基异莰醇（2-MIB）和土臭素（GSM）,且UV/PS的降解效果更优。重碳酸根和天然有机物均可以显著抑制UV/H₂O₂和UV/PS降解2-MIB和GSM的效能,但对UV/PS体系的抑制作用显著强于其对UV/H₂O₂体系的抑制作用,结果导致UV/H₂O₂在重碳酸根或者天然有机物存在时降解2-MIB和GSM的效果优于UV/PS体系。由于实际水体中通常含有较高浓度的重碳酸根和天然有机物,因此UV/H₂O₂降解松花江水体中2-MIB和GSM的效果优于UV/PS体系。通过此研究可知UV/H₂O₂相对于UV/PS更适于实际水体中2-MIB和GSM的去除。更多还原

【Abstract】 Both ultraviolet/hydrogen peroxide（ UV/H₂O₂） and ultraviolet/persulfate（ UV/PS）are effective in the degradation of 2-methylisoborneol（ 2-MIB） and geosmin（ GSM） in pure water. The degradation efficiency of UV/PS was better than that of UV/H₂O₂. Both bicarbonate and natural organic matter（ NOM） could inhibit the removal of 2-MIB and GSM significantly. However,the inhibition effect on UV/PS system was more significant than that on UV/H₂O₂ system,resulting in a fact that UV/H₂O₂ showed higher removal efficiencies of 2-MIB and GSM than UV/PS system in the presence of bicarbonate or NOM. Due to the high contents of bicarbonate and NOM in real water,UV/H₂O₂ was more effective than UV/PS in the degradation of 2-MIB and GSM contained in Songhua River water. This study suggested that UV/H₂O₂ might be a better choice than UV/PS when treating 2-MIB and GSM in real water.更多还原
