Taste and odor problems in drinking water as well as their sources were introduced.The composition and classification of odorous compounds were summarized.The detection and control technologies of odorous compounds were discussed.The detection methods of odorous compounds include sensory analysis,instrument analysis and comprehensive analysis.Flavor profile analysis is the most common sensory method.More attention is paid to pretreatment of water samples in instrument analysis,and solidphase extraction is an effective pretreatment method.The removal processes of typical odorous compounds mainly include activated carbon adsorption,chemical oxidation,biological treatment and combination process.The analysis of studies in the last 10 years shows that China needs to conduct as soon as possible a research on standardized testing methods and control technologies of odorous compounds in drinking water,and treatment processes required for different water sources,different seasons and different odorous compounds should be developed to ensure drinking water safety.
