Brief analysis on environmental control strategies and design standards for urban underground sewage treatment plants

In view of the problem that the air environment is often out of control because the deodorization system and ventilation system of underground sewage treatment plants are not considered as a whole in the traditional design, this paper analyses the underground space air environment characteristics, pollutant discharge standards, initial concentration standards of pollutants and key points and difficulties of odor treatment, combined with the practical experience of several underground sewage treatment plants. The environmental control strategy and design standard of the combination of ventilation and deodorization system in underground sewage treatment plants are put forward.
