With the increasing attention to environmental protection in recent years, the odor emitted from municipal drainage pipelines (such as H2S, NH3, etc.) has attracted more attention. Odors directly affect the living environment of residents and seriously impact people's perception and urban environment, causing discomfort and disgust. At the same time, there are also large amounts of aerosols formed by viruses and other substances in the gases emitted from drainage pipelines. In 2020, the novel coronavirus was detected in sewage treatment plants and sewage systems. In addition to human-to-human transmission, aerosols emitted from sewage systems also have the potential for transmission, seriously affecting the health of local residents. The odors and aerosols emitted from municipal drainage pipelines need to be effectively treated. The research institute combines practical situations with mathematical model simulations to analyze the causes, properties, and emission paths of odorous gases and aerosols emitted from drainage pipelines. It engages in research on pipeline odor removal processes and equipment.
