Design of deodorization system for Xiong’an comprehensive waste treatment facility

The ventilation of the comprehensive waste treatment facility plant arranged in the sunken space is in bad condition, and there are many odor release sources in the plant. In this paper， the sources of odor in waste treatment facilities are analysed, and the design principles and methods of ventilation and deodorization system in the sunken workshop are expounded based on air volume balance calculation and negative pressure control of the waste pit. Based on the analysis of actual project case data, this paper proposes some suggestions on the operation control strategy of the deodorization system.
