With the acceleration of urbanization, more and more enterprises are choosing to move out of cities and into parks, forming a trend of enterprise agglomeration and development. However, this has also caused industrial parks to become major gathering places for VOCs (volatile organic compounds) and odor substances. Frequent complaints about environmental pollution and odor not only restrict the sustainable development of the park, but also have a serious impact on the normal life of surrounding residents. In this context, the application of odor sensors is particularly critical.
1. Analysis of the current situation of VOCs and odors in the park At present, there are many companies in the industrial park and there are many types of waste gas emissions, among which VOCs and odor substances are the main sources of pollution. The presence of hydrogen sulfide, ammonia, methyl mercaptan, odor factors, TVOC and other substances not only seriously pollutes the atmospheric environment, but also interferes with residents’ lives. Therefore, it is urgent to carry out atmospheric environment monitoring and control work in the park.
2. Governance plan
“Inspection”: First, with the help of advanced navigation monitoring and portable monitoring equipment, a comprehensive investigation of the exhaust gas emissions of enterprises in the park is carried out to understand the base number of exhaust gas emissions of each enterprise. At the same time, a fingerprint database of enterprise exhaust gas characteristics is constructed to screen out optimal control factors in the park and provide data support for subsequent environmental monitoring and control.
“Measurement”: Based on the investigation and the principle of “source-diffusion pathway-receptor”, select a suitable atmospheric grid monitoring system and build a network for monitoring the park’s atmospheric environment. This network will have the ability to comprehensively monitor “time, space, and factors”, provide timely and accurate early warning services, and provide strong support for the environmental management of the park.
“Tracing”: By building a “characteristic factor library + small-scale meteorological field + traceability strategy library”, using platform early warning and odor complaints as trigger events, combined with online early warning traceability and offline navigation methods, we can achieve precise locking of pollution sources. This will help quickly find the source of pollution and provide clear targets for subsequent treatment work.
“Control”: Provide integrated hosting services with the goal of improving the environmental quality of the park. Formulate key control projects, key control factors, closed-loop control mechanisms, etc. to form a comprehensive and systematic governance plan. At the same time, we will strengthen environmental protection publicity and training for enterprises, improve their environmental awareness, and create an environmental protection atmosphere in which the park, enterprises, and residents jointly participate.
3. Odor sensors in the atmospheric grid monitoring system: According to the national “Odor Pollutant Emission Standard (GB14554-1993)”, the 9 parameters of the national standard for controlling odor substances are also called “eight gases and one taste”, among which the eight gases refer to: ammonia, Hydrogen sulfide, methyl mercaptan, methyl sulfide, styrene, trimethylamine, carbon disulfide, and dimethyl disulfide all refer to the nine parameters of “odor”.
Therefore, Gongcai.com recommends the selection of resolution PPB level odor sensor as follows:

In chemical industrial parks, odor sensors can be placed in key areas to monitor the concentration of odorous substances in the air in real time. Once the odor exceeds the standard, the sensor will immediately sound an alarm to remind managers to take appropriate measures. At the same time, through the analysis of sensor data, the source of odor can be accurately determined to provide guidance for subsequent treatment work.
4. Future Outlook
With the continuous development of science and technology , the performance of odor sensors will continue to improve, and the monitoring accuracy and scope will also continue to expand. In the future, odor sensors are expected to play a greater role in the traceability and precise control of odors in chemical industrial parks, helping to create odor-free chemical industrial parks and providing a strong guarantee for the green development of the chemical industry.
In short, traceability and precise management and control of odor are important tasks for environmental protection in chemical industry parks. Through the application of odor sensors, we can more effectively trace the source of odors and accurately control them, ensuring the environmental quality of the park and the quality of life of residents. Looking to the future, we expect odor sensors to play a greater role in odor control in chemical industry parks and promote the sustainable development of the chemical industry.
