[ Market analysis of chemical machinery and equipment network ] Recently, * released the "12369" environmental protection report from 2020 to the present, which shows that from January to September this year, air pollution reports exceeded half of the total number of reports, and malodorous reports accounted for the atmosphere.
About half of the report.

According to the data, since the 2016* environmental protection inspection, cases of malodor and odor harassment have been common all over the country, and it has become one of the key contents of environmental protection inspections.

There are a wide range of odor pollution sources.
The industries involved include petroleum refining, chemical, pharmaceutical, rubber, paper, food processing and other point sources, as well as sewage rivers, sewage treatment plants, landfills, livestock and poultry breeding, and catering oil fume.
, Non-point source, diffuse source.
Among the areas where the petrochemical and chemical industries are concentrated, 90% of environmental complaints come from odor problems.

Therefore, the treatment of malodorous gas in industrial enterprises has attracted widespread attention.

Professionals pointed out that there are two main reasons for the formation of odor pollution in the industrial park, namely, the formation of the source and the formation of the secondary.
Simply put, it means that the raw and auxiliary materials are diffused, dripped, and odor pollution caused by the volatilization of the surface of the sewage treatment facilities in the enterprise during the transportation, production and storage; or the raw and auxiliary materials diffuse into the air, and the air Through microbial decomposition, high-temperature reactions, anaerobic fermentation, light, etc.
, other intermediate products with malodorous properties are formed among the substances in it.

　　In recent years, the relevant departments of our country have also paid attention to the fact that reports of malodors and odors remain high.

　　The Air Pollution Prevention and Control Law stipulates that “Enterprises, institutions and other producers and operators who produce malodorous gases in their production and business activities shall select sites scientifically, set up reasonable protective distances, and install purification devices or take other measures to prevent the emission of malodorous gases.
.
"

　　At the end of 2018, * released the "Emission Standards for Odor Pollutants (Draft for Comment)", involving seven aspects including tightening the limits of eight pollutants, improving emission and monitoring requirements.

　　In addition, the upgraded "Odor Pollution Environmental Monitoring Technical Specifications" stipulates the whole process of monitoring the odor pollution discharged by the ambient air and various odor pollution sources (including waters).

　　In terms of treatment methods, activated carbon adsorption, biological filtration method, low temperature plasma method, plant liquid spray deodorization and UV photo-oxygen catalytic waste gas purification are the current methods of malodor treatment in industrial enterprises.

　　Even so, in the treatment of malodorous gases, there are still problems such as backward monitoring and analysis methods, the unfair principle of implementing different emission limits in different regions, and the urgent need to increase the number of pollutant projects that need to be resolved.

　　On the other hand, the timeliness and uncertainty of odor emission have led to the difficulty of obtaining evidence and law enforcement by environmental protection departments.
Therefore, it is urgent to establish a real-time, efficient and rapid online monitoring system for odorous gases to monitor the situation of odor emissions.
Hourly continuous monitoring.

　　Specifically at the enterprise level, different odor control technologies have different applicable scopes.
The removal effect is affected by factors such as the type of odor emission source, emission concentration, and emission parameters, so it needs to be further improved.

　　Under this circumstance, some experts analyzed that as the prevention and control of air pollution gradually enters the subdivision field, the market space in the fields of treatment, monitoring and supervision induced by odor pollution is expected to reach the order of hundreds of billions.
