摘要:
于2013年每月测定了苏州太湖饮用水源地9种异味物质含量及TP、TN、水温、藻密度等指标,结果表明,苏州太湖饮用水源地主要检出的异味物质有2-甲基异崁醇、土臭素、β-环柠檬醛和β-紫罗兰酮等4种。2-甲基异崁醇年均值是其嗅觉阈值的2.9倍,水体主要表现为土霉味。根据异味物质与环境因子相关性分析结果及相关文献讨论,水温是影响异味物质含量的重要因素。微囊藻等藻类对β-环柠檬醛和β-紫罗兰酮有明显贡献。

Abstract:
Nine off flavor compounds, and several environmental factors such as TP, TN, water temperature, and algal density et al. in drinking water sources of Taihu in Suzhou were measured monthly in 2013. The main off flavor compounds were 2-methylisoborneol (2-MIB), geosmin,β cyclocitral, and β ionone. Annual average concentration of 2 MIB was 2.9 times of its odor threshold value, which caused earthy odor of the water. According to correlation analysis between off flavor compounds and environmental factors, and together with discussion from related literature, water temperature was one of the main factors affecting concentration of off flavor compounds. Microcystis contributed obviously to the occurrence of β cyclocitral and β ionone.
