Abstract:
Ozonation was applied to investigate the removal efficiency of 6 odorous organic compounds in eutrophic water from Taihu Lake (Wuxi). The results showed that the ozonation process could be described by first order kinetic model and the overall kinetic rates of the odorous compounds were determined by their chemical characteristic and structure, which could be ranked: beta-Ionone (3.3 x 10(-3) s(-1)) > beta-Cyclocitral (2.8 x 10(-3) s(-1)) > 2,4-Decadienal (2.7 x 10(-3) s(-1)) > Neryl Acetone (2.2 x 10(-3) s(-1)) > Geosmin (1.4 x 10(-3) s(-1)) > 2-Methylisoborneol (5.6 x 10(-4) s(-1)). Ozonation of eutrophic water led to the formation of a series of aldehydes, ketones, alcohols and esters. The influence of bicarbonate and natural organic carbon on odorous compounds ozonation were further investigated, results showed that the bicarbonate could restrain the effect of ozonation by cutting down the radical pathway and natural organic carbon in the water by competition with target compounds.
