Problems solved by technology

Due to the particularity and complexity of odor pollution, there has been a lack of in-depth and systematic research on the emission characteristics and sources of volatile odorous substances in the world so far.
[0005] Due to the particularity and complexity of odor pollution, there has been a lack of in-depth and systematic research on odor pollution source analysis technology in the world.
There are many kinds of odorous substances emitted by various pollution sources. The concentration level, chemical activity and source of each species vary greatly, and there are many interactions between them. Odor pollution is affected by the surrounding environment such as meteorology, terrain, and terrain. Larger, it is difficult to grasp its pollution diffusion law

Embodiment Construction

[0044] The fine source analysis method for atmospheric odor pollution of the present invention will be described in detail below in conjunction with the embodiments and accompanying drawings.

[0045] The fine source analysis method of atmospheric odor pollution of the present invention is based on the investigation data of regional odor pollution sources, puts forward related concepts such as odor characteristic markers and odor fingerprints, and establishes fingerprint database and fingerprint pattern recognition of regional odor pollution sources method, transform the spectral information into a quantitative matrix acceptable to the computer, and realize rapid and accurate comparison between the spectral graphs, which provides a new way and method for the diagnosis and analysis of odor pollution accidents and the rapid tracing of the source of odor pollution.

[0046] The invention firstly determines the typical areas of the odor pollution according to the odor complaints, e...

Abstract

An atmosphere fetor pollution fine source apportionment method comprises determining a fetor pollution source surveying area; performing fetor pollution source survey and establishing a real, reliable and complete fetor pollution information database; based on the foundation of fetor source survey, analyzing influence on environment by a pollution source in different conditions and judging a main fetor pollution source influencing the surveying area; identifying characteristic markers of various emission sources; establishing fetor fingerprints capable of reflecting emission characteristics of the pollution sources; identifying the fingerprints by means of a fuzzy clustering model, programming by adoption of Matlab software and achieving rapid and accurate compare among the fingerprints; and establishing an atmosphere fetor pollution fine source apportionment model. The atmosphere fetor pollution fine source apportionment method is capable of finding the sources of fetor pollutants rapidly and accurately, high in practicality and wide in popularization and application and capable of providing a reliable technical guarantee for environment management departments to deal with an emergent fetor pollution accident and control a pollution risk.

Description

technical field [0001] The invention relates to an environmental pollutant source analysis method, in particular to a fine source analysis method for atmospheric odor pollution, which is suitable for fine source analysis of atmospheric odor pollution. Background technique [0002] Odor pollution is one of the prominent environmental problems in the rapid development of industrialization and urbanization in my country, and it is also a hot and difficult issue that plagues environmental protection management departments. To clarify the source and contribution of odor pollution is the key to the management and control of odor pollution. Due to the particularity and complexity of odor pollution, there has been a lack of in-depth and systematic research on the emission characteristics and sources of volatile odorous substances in the world so far. Odor pollution is mostly compound pollution, and there are many industries involved in odor pollution, including point sources such a...
