Foul odor is a common environmental pollution problem, which has a serious impact on people's lives and health. The odor is mainly industrial waste gas, landfills, livestock and poultry farms, sewage treatment plants, etc., which contain hydrogen sulfide, ammonia, methyl mercaptan, volatile organic compounds and other harmful substances, so effective monitoring and treatment of the odor is an important task to protect the environment.
At present, the monitoring method of odor pollution mainly adopts the traditional instrument method, that is, the qualitative and quantitative analysis of various components in the odor by using various instruments, but this monitoring method has some limitations, such as difficult sampling, time-consuming analysis, and non-real-time results, so it is not suitable for large-scale and rapid monitoring. In order to solve these problems, a new type of environmental monitoring tool - vehicle-mounted odor monitor came into being.
The vehicle-mounted odor monitor is a device that uses the vehicle as a mobile platform and is equipped with high-sensitivity sensors and analytical instruments to realize real-time, continuous and rapid monitoring and positioning of odorous substances in the air. It can freely carry out navigation monitoring in different areas and times according to the monitoring purpose and route, and obtain the type, concentration, distribution and quality of odorous substances in the air in real time, so as to provide a scientific basis for the treatment and traceability of odor. The main advantages of vehicle-mounted odor monitors are as follows:
1.Wide monitoring range and large coverage area: According to the actual needs, the appropriate route and speed can be selected to monitor different areas and directions, so as to obtain more comprehensive and detailed air quality information, and avoid the blind spots and errors of traditional point or surface monitoring.
2.High monitoring efficiency and fast response speed: The use of advanced sensors and analytical instruments can achieve second-level response and millisecond-level resolution of odorous substances in the air, which greatly shortens the time of sampling and analysis, and improves the efficiency and accuracy of monitoring. At the same time, the vehicle-mounted walk-in odor monitor can also transmit the monitoring data to the background server and data platform in real time through the wireless network, which facilitates the management and analysis of data.
3.Strong monitoring function and abundant data: not only can the odorous substances in the air be monitored, but also other environmental parameters, such as temperature, humidity, air pressure, wind speed, wind direction, particulate matter, etc., so as to obtain more environmental information and analyze the causes and influencing factors of odor. In addition, the vehicle-mounted odor monitor can also record the time and location of monitoring through the GPS recorder, providing a basis for the spatial distribution and traceability of odor.
For example, in Chengdu High-tech Zone, the vehicle-mounted odor monitor has carried out navigation monitoring of atmospheric VOCs (atmospheric volatile organic compounds) in the area, using modern rapid monitoring technology, which can analyze and quickly detect more than 300 kinds of organic waste gases during driving, and depict the pollution map according to the total concentration of pollutants monitored, intuitively provide regional and enterprise pollutant emissions, and realize the coordination of "measurement and management", so as to comprehensively and quickly lock the key pollution sources. At present, it has been sailing for 132 days, 540 hours, nearly 9093km, more than 100 VOCs substances have been monitored, and a total of 247 abnormal points have been found.
Vehicle-mounted odor monitor is a new type of environmental monitoring tool, which provides new ideas and methods for odor monitoring and control, and provides more comprehensive and efficient services for environmental protection. The equipment has broad application prospects and can be used for various occasions and purposes, such as the monitoring and treatment of odor pollution sources such as industrial parks, landfills, sewage treatment plants, livestock and poultry farms, as well as the monitoring and early warning of emergency situations such as major activities and events, environmental emergencies, and heavily polluted weather.
