In recent years, China’s total environment of water body has been in deterioration, and accidental/sudden pollution in water source happened frequently, which pose a serious threat to the security of urban water supply. The traditional technological process “coagulation-sedimentation- filtration-oxidation” which can not effectively deal with sudden pollution in raw water, is adopted by the overwhelming majority water plant in China. In order to improve the security of drinking water, it is essential to carry out studies on the emergent treatment of sudden pollution in water source. The background of this paper was based on the sudden taste and odor pollution underwent in Huyan water plant of Taiyuan City. Fenhe Reservoir, the water source of Huyan water plant, was investigated during the study. The chemical compound of the taste and odor and its origin were studied. According to the flavor origin, an emergent treatment technology suited for sudden taste and odor pollution was chosen after comparison, and the operation parameters were optimized by jar experiment. The engineering project of taste and odor control was designed, followed by the risk analysis of this emergent processing technology. The main conclusions in this study were listed as follows: The water quality of Fenhe Reservoir was in normal level, and all of the indexes investigated during the study satisfie
