According to the secondary pollution problem of odorous compounds which produced by urban sewage pumping station, the odorous compounds hazards and health risk were assessed. Taking 6 urban sewage pumping stations in north China as an example, firstly, the main components of odorous compounds in different positions of sewage pumping stations was monitored and analyzed. Secondly, the odorous compounds strength grading method of Japan was used to assess the hazards of odorous compounds. Then, the health risk of pumping station operators was also assessed. The results showed that the strength of odorous compounds was reached the level of giant stink, and the safety of operators was threatened greatly. Finally, according to the characteristics of the 6 sewage pumping stations above, through a comprehensive analysis of existing deodorization processes, the deodorization process and design flow for the 6 sewage pumping stations were defined.
