Application environment of odor on-line monitoring system

Malodorous gas is a kind of gas with pungent odor, and the pollutants emitting malodorous odor are called malodorous substances. According to the different sources and properties, odor substances can be divided into three categories: inorganic odor, organic odor and biological odor. At present, malodorous gas pollution has become a global environmental problem.
Due to the increasingly serious environmental pollution, it is necessary to strengthen environmental protection, so as to guarantee the quality of people’s life. At present, air pollution monitoring and early warning is one of the important means to solve environmental problems. Therefore, the online monitoring system of air pollution source has a special demand.
Industrial enterprise
Industrial enterprises are the main source of air pollution. The waste gas produced in the process of industrial production contains a large number of malodorous substances, such as sulfur oxides, nitrogen oxides, hydrocarbons, etc., which will cause pollution when discharged into the atmosphere during the production process. When the concentration of enterprise waste gas reaches the standard, it is necessary to take effective measures in time to deal with industrial waste gas in time. So the treatment of industrial waste gas is very important. In addition, with the progress of society and the development of science and technology, it is inevitable to conduct online and real-time monitoring of odor. The on-line monitoring system of air pollution source can effectively solve the problem of malodorous gas emission.
Agricultural production
In the process of agricultural production, fertilizers, pesticides, feed and other agricultural inputs in the process of use will produce a lot of odor, which will have a certain impact on the environment, so we must do a good job of environmental protection, so as to avoid the impact on the environment. For example:
1. In the process of livestock and poultry breeding, the use of a large number of agricultural inputs such as feed and fertilizer will produce a large number of foul gases. In addition, in the process of breeding, clean production technology should be actively implemented and clean feed and fertilizer should be used to meet the needs of livestock and poultry farming.
2. Agricultural inputs such as pesticides, fertilizers and additives will also produce a large number of foul gases in the process of use. On this basis, a variety of measures should be adopted to reduce or avoid the use of pesticides and fertilizers on the environment.
3. When fetid gases such as animal excreta and garbage are produced in the process of treatment, the detection of exhaust emissions should be strengthened. In addition, the choice of fertilizer and feed should be reasonable.
Family house
Garbage, toilet and sewage management are the main sources of odor in domestic homes. And fetid gases from garbage and toilets have a serious impact on residents’ quality of life. In the family residence, the online odor gas monitoring system can be established to monitor the odor concentration in real time, calculate the odor concentration threshold according to the needs of users, and carry out early warning and treatment when the data exceeds the standard.
Environmental monitoring station
The online odor monitoring system can monitor the concentration of odor substances in the air in real time, such as ammonia and hydrogen sulfide, and judge the air quality by monitoring the concentration of these gases in real time.
Once an exception occurs, the system will notify the management personnel in the first time so that measures can be taken in time. In the current development stage, the online monitoring system of malodorous gas has become an indispensable part of air pollution control.
Environmental sanitation department
In Chinese urban sanitation departments, some enterprises that use large machinery for garbage removal and collection need to pay more attention to odor pollution in key areas such as garbage ponds and garbage transfer stations. If the smell is serious, the environmental health department will investigate immediately and take effective measures to eliminate the impact in the first place. For example, if hazardous materials are present in the garbage pond, workers clean it up and then either flush the site with water or dispose of it in a landfill.
The online odor monitoring system can monitor the pollution source in real time and quickly discover the change of odor substance concentration and pollution in the environment. If the pollutant concentration exceeds the control value of the environmental protection department, the system will automatically send an early warning message to the manager, providing important data support for the enterprise’s environmental protection work.
