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 organ

Embodiment 1

[0029] An atmospheric odor pollution traceability system, characterized in that the system includes an information management system, a fingerprint system, a traceability model system, and a result display system; wherein the information management system performs input, storage, modification and display of pollution source emissions and environmental odor gas information ; The fingerprint system screens fingerprints, establishes and displays odor fingerprints; the traceability model system calculates the similarity coefficient of odor fingerprints; the result display system displays traceability results on lists and GIS maps;

[0030] 1. The information management system includes:

[0031] (1) Pollution source information management: By collecting typical odorous gas samples discharged from various pollution sources, including exhaust outlet samples of pollution sources and fugitive emission samples, qualitative and quantitative analysis is carried out by chromatography or chr...

Embodiment 2

[0046] A method for traceability of odor pollution based on odor fingerprints, the specific implementation steps are as follows:

[0047] A. Identify suspected sources of contamination

[0048] According to the odor complaints (including the time of complaint occurrence, odor quality, odor intensity, odor frequency, and duration), screen suspected odor pollution sources around the complaint point.

[0049] B. Sampling and Analysis of Pollution Source Emissions

[0050] According to the production process, production rules, emission characteristics and other information of pollution sources, collect typical odorous gas samples (including exhaust outlet samples of pollution sources and fugitive emission samples) emitted by various pollution sources, and use chromatography or chromatography-mass spectrometry for qualitative and quantitative analysis Analyze, obtain the material composition and material concentration of the pollution source gas sample, and enter it into the datab...

Embodiment 3

[0070] In this example, residents of a residential area in Longgang District, Shenzhen often complained about the bad smell of surrounding factories and disturbed residents. The environmental management department found through investigation that there are many factories emitting odorous gases around the residential area. Factories blame each other, so the environmental management department cannot determine which factory the odor pollution comes from through manual investigation. The atmospheric odor pollution traceability system constructed by the present invention helps the environmental management department identify the source of pollution causing the odor pollution in the community, and traces the source according to the following steps:

[0071] A. According to the complaints of residents in the community, 7 factories were screened out as the suspected odor pollution sources; according to the investigation of the factories, the gas emitted from the exhaust pipes of the f...

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...
