Atmosphere odor pollution tracing system and application

Abstract

The invention relates to an atmosphere odor pollution tracing system based on an odor fingerprint spectrum and similarity analysis. The system comprises an information management system, a fingerprintspectrum system, a tracing model system and a result demonstration system. The system comprises steps of pollution source information management, odor pollution information management, odor fingerprint spectrum establishment, similarity calculation of the tracing model system, and tracing result display. According to the system provided by the invention, on the basis of information management system collection, stored pollution source discharge and environment odor gas related data, environment and pollution source odor fingerprint spectrums are established through the fingerprint spectrum system, similarity coefficients of the environment and pollution source odor fingerprint spectrums are calculated through the tracing model system on the basis of an included angle cosine method, the similarity of the environment and pollution source odor fingerprint spectrums is displayed on the system, then possible sources of odor pollution can be judged, precise recognition on odor pollution sources can be achieved, difficulties of odor pollution tracing can be solved, technical defects of odor pollution complaint management can be overcome, and effectiveness and authority of environment administrative departments in odor pollution supervision and law enforcement can be improved.

Description

technical field [0001] The invention belongs to the technical field of odor pollution traceability, and in particular relates to an odor pollution traceability system based on odor fingerprints and graph similarity analysis. Background technique [0002] With the rapid development of my country's social economy, people's awareness of environmental protection and the requirements for the living environment are getting higher and higher. As a kind of pollution that disturbs the people and endangers human health, stench (odor) has become the most intense environmental problem complained by urban residents in our country. one. Odor pollution complaints in Shanghai, Shenzhen, Guangzhou, Tianjin and other cities account for more than 30% of environmental complaints, and the proportion of complaints near industrial zones can even reach 90%. Odor pollution has increasingly become a serious environmental and social problem. Due to its wide range of sources and complex components, the...

Problems solved by technology

Fingerprint technology has been widely used in the fields of chemistry and traditional Chinese medicine in recent years, but it has not been found to be used in the traceability of air pollution, especially the traceability of atmospheric odor pollution.

Different from general air pollutants, odor pollution has the characteristics that can be perceived by the human body. The traceability of odor pollution pays more attention to the odor pollutants that can be perceived by human olfactory organs and have a strong smell. The main problem of applying fingerprint technology to trace the source of odor pollution is ① Lack of information management of odor pollutant emissions from pollution sources and environmental odor pollution events; ② Substances screened during the establishment of fingerprints are not representative; ③ The size of pollutant gases is not considered in the similarity analysis of fingerprints, resulting in unrealistic traceability results sources of odor pollution
