苏州市太湖异味物质主要成分研究

Research on Main Component of Odor Compounds in Taihu Lake in Suzhou City

针对太湖水体异味问题,对2013年以来的苏州太湖饮用水源地和太湖苏州辖区异味物质开展调查,统计异味物质的检出率及浓度,确定太湖苏州辖区异味物质主要成分为2-MIB、土臭素、β-环柠檬醛和β-紫罗兰酮,苏州太湖饮用水源地异味物质主要成分为2-MIB。异味物质主要成分的确定为进一步探索异味的来源提供基础,特别是为水源地异味的监控预警提供科学参考。

Investigation of odor compounds both in drinking water sources of Taihu in Suzhou and the whole Taihu areas in Suzhou from 2013, The results of the detection rates and concentration showed that the main odor compounds in Suzhou Taihu are 2-MIB, geosmin, β-cyclocitral and β-ionone. The main odor compound of Taihu drinking water sources is 2-MIB. This investigation provide a basis for further exloration of the source of odor compounds, particularly to provide scientific reference for the odor monitoring and early warning of the drinking water sources.
