太湖饮用水源地主要异味物质时间变化规律研究

Study the Time Relationship with the Main Odor Source Water in Taihu

以苏州饮用水源地的主要异味物质2-甲基异莰醇、土臭素等为研究对象,采用顶空固相微萃取-气相色谱质谱法对其含量进行测定。对饮用水源地9种异味物质监测数据进行统计分析,苏州水源地的主要异味物质分别为是：β-环柠檬醛、β-紫罗兰酮、2-甲基异崁醇、土臭素等。异味物质浓度高的月份主要在4~10月。异味物质含量跟降雨量也呈现一定的相关。

2-methylisoborneol and Geosmin are the main odor materials for potential threat to water safety. There were the main objects of study. They Determination of the contents in water are gas chromatography-mass spectrometry with headspace solid phase micro-extraction. Statistical analysis of the drinking water sources in 9 kinds of odor monitoring data, The main odor material respectively is：, β Cyclocitral, Beta-ionone, 2-MIB, Geosmin,. The month of high concentration of odor substances was mainly in 4~10 months. Odor material content and rainfall also showed a certain correlation.
