The characteristics of odor and VOCs emitted from a sewage treatment plant was investigated to provide the basic informations in the design of odor and VOCs treatment processes. The sewage treatment plant which treated domestic wastewater only and consisted of a flow equalization tank, thicker, and sludge container was selected. Odor and VOCs sampled three times (June - July) at the temperatures ranging from 24℃ to 27℃ were analyzed by GC/MS and GC/FPD. Odors were hydrogen sulfide, dimethylsulfide, ammonia, and styrene. Among them, the main compounds were dimethyldisulfide (14.45~2,340.91 O.U.) and ammonia (18.51~16,520 O.U.). The order of odor dilution ratio and odor unit can be listed as follows : Sludge container ＞ Flow equalization tank ＞ Thicker. The main VOC produced from sewage treatment plant was benzenes, and the others were dichloromethane, toluene, ethylbenzene, m,p-xylene, styrene, 1,2,4,-trimethylbenzene, 1,3-dichlorobenzene, and 1,2-dichlorobenzene. The concentration of toluene of a flow equalization tank, thicker, and sludge container were produced from 70.38 ppb to 103.07 ppb, from 28.18 ppb to 40.35 ppb, and from 67.92 ppb to 180.26 ppb. The producing order of VOC can be listed as follows : Sludge container ＞ Flow equalization tank ＞ Thicker.
