[Review on the tastes and odors compounds in drinking water of China].
Tastes and odors problems (T&Os) in China and studies on T&Os are reviewed, especially on aspects of the present situation in China, sources of T&Os in water, T&Os qualitative & quantitative technology, odorant composing characters, removal technologies and processes on typical odorant in drinking water. This review aims to elucidate that besides microbial metabolism product such as geosmin and 2-MIB, organic anaerobic decomposition product such as thiol-thioether were also main odorant in drinking water of China. Thiol-thioether odorant which was found in drinking water of Dongguan in 2006 for the first time, was proved to be the main odorant in Taihu Lake drinking water risk in 2007 as well. Geosmin and 2-MIB were more easily removed by adsorption than oxidation, but thiol-thioether was easily removed by oxidation not by adsorption. In order to cope with T&Os in different water source, different season and different odorant,studies on odorant composing character, removal technology, mechanism and process of typical odorant should be carried out as soon as possible in China.
