Embodiment 1

[0033] A method for traceability of odor pollution based on odor fingerprints, the specific implementation steps are as follows:

[0034] A. Identify suspected sources of contamination

[0035] 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.

[0036] B. Sampling and Analysis of Pollution Source Emissions

[0037] 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 2

[0057] 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. Utilize the present invention to help the environmental management department to identify the source of pollution that causes the odor pollution in the community, and trace the source according to the following steps:

[0058] A. According to the complaints of residents in the community, 7 factories were identified as the suspected source of odor pollution.

[0059] B. According to the investigation of the factory, the gas discharged from the exhaust pipe of the factory workshop was collected, and qu...

Abstract

The invention relates to a stink fingerprint spectrum based stink pollution source tracing method. The method comprises the following steps: A, determining a suspected pollution source; B, discharging, sampling, analyzing the pollution source; C, sampling and analyzing an environment stink gas; D, screening a stink pollutant; E, constructing a pollution source and environment stink fingerprint spectrum; F, calculating the similarity through a source tracing mode; and G, identifying the pollution source according to the similarity. The stink fingerprint spectrum is constructed through the fingerprint spectrum technology and the odor threshold of a stink substance, the similarity coefficient of the pollution source and environment stink fingerprint spectrum is calculated by using an includedangle cosine method, so that the possible source of the stink pollution is judged, the source of the stink pollution is rapidly and accurately identified, the difficult problem of tracing the sourceof the stink pollution is solved, the technical defect of complaint management of the stink pollution is overcome, and the effectiveness and the authority in supervision and law enforcement of the stink pollution of the environmental management department are improved.

Description

technical field [0001] The invention belongs to the technical field of odor pollution traceability, and in particular relates to a method for traceability of odor pollution 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 component...
