In-depth fight against pollution prevention and control, instruments to report
.

 

In the past 2021, the eight binding indicators in the field of ecological environment in the national economic and social development plan have been successfully completed, pollutant emissions have continued to decline, the quality of the ecological environment has been significantly improved, the people's sense of gain in the ecological environment has been further enhanced, and ecological and environmental protection has been achieved.
The 14th Five-Year Plan is off to a good start
.

 

But at the same time, we need to be soberly aware that China's ecological and environmental protection work is still facing multiple pressures at this stage
.
The 2022 National Ecological Environmental Protection Work Conference proposed to continue to promote the prevention and control of air, water and soil pollution, promote the implementation of key emission reduction projects, and focus on solving outstanding ecological and environmental problems
.

 

Therefore, it is necessary to focus on the elimination of heavy pollution weather, the prevention and control of ozone pollution, the pollution control of diesel trucks, the coordinated control of PM2.
5 and ozone pollution, and the continuous improvement of air quality
.
It is necessary to solidly promote the management of urban black and odorous water bodies, the protection and restoration of the Yangtze River, the ecological protection and management of the Yellow River, the comprehensive management of key sea areas, and the protection and construction of beautiful rivers and lakes and beautiful bays
.
It is necessary to promote the prevention and safe utilization of soil pollution in agricultural land, and implement actions to prevent and control the source of heavy metal pollution such as cadmium in agricultural land soil
.

 

　　In-depth fight against pollution prevention and control, instruments to report
.

 

　　First of all, in order to strengthen the monitoring and control of air pollution in the promotion of heavy pollution weather elimination, ozone pollution prevention and control, and diesel truck pollution control, China has built an environmental monitoring air station.
Its main equipment includes online ion chromatography, heavy metals, OC/EC (organic carbon/elemental carbon), single particle time-of-flight mass spectrometer, VOCs (volatile organic compounds), black carbon, turbidity, aerosol lidar, wind profiler radar, microwave radiometer, etc.
, mainly for particulate matter and VOC data Perform audit analysis
.

 

　　Ozone pollution prevention and control, the current ozone detection instruments and technologies include ozone space-time distribution detection lidar system, grating spectral filter, ground-based ozone radar observation, vehicle-mounted ozone radar observation,
etc.
Some provinces and cities have already deployed atmospheric ozone lidar systems, ozone sondes, etc.
, and have been successfully applied
.
The application of these instruments and technologies provides important technical support for ozone pollution control
.

 

　　Pollution control of motor vehicles such as diesel trucks
.
Through the use of various advanced vehicle monitoring and exhaust remote sensing, it is conducive to the construction of an intelligent vehicle emission monitoring system, and a management monitoring center information integration platform that supports the operation of the system.
In the process of urbanization, it is helpful to solve urban pollution problems.
, it can play a better control of motor vehicle exhaust pollution
.

 

　　Secondly, it is necessary to solidly promote the treatment of urban black and odorous water bodies, the protection and restoration of the Yangtze River, and the ecological protection and management of the Yellow River.
Black and odorous water bodies are an extreme phenomenon of water pollution and are currently a more prominent environmental problem
.
Traditional screening and monitoring methods require people to arrive at the scene, while remote sensing technology can quickly locate black and odorous water bodies in a wide range, saving time and resources, and can dynamically reflect changes
.
Therefore, as a large-scale black and odorous water monitoring method, remote sensing technology has the advantages of low cost, wide coverage and fast speed compared with traditional ground monitoring methods
.

 

　　In the protection and restoration of the Yangtze River, through monitoring, it is possible to analyze the impact of different pollution sources on the water environment quality.
The equipment provides necessary technical support for the management department to aim at the key goals of pollution control, supports the evaluation of the implementation effect of the project, and provides important support for the management department to make scientific decisions on water resources protection
.

 

　　In the ecological protection and governance of the Yellow River, monitoring of water environment protection and pollution prevention is very important.
The monitoring of water environment and the construction of automatic monitoring stations for water environment quality are inseparable from the application of water quality analysis instruments
.
With China's emphasis on the water environment, the market demand for water quality monitoring instruments has been continuously expanded, and China's water quality monitoring market has shown a rapid development trend
.

 

　　In addition, in soil pollution prevention and control, soil monitoring, as the "pioneer" of soil pollution remediation, will be the first to benefit
.
Due to the concealment, hysteresis and accumulation of soil pollution, it is necessary to sample and test relevant instruments and equipment to obtain specific data before taking corresponding control measures and monitoring the effect of soil remediation in the later stage, which requires a large number of soil monitoring instruments.
Equipment; according to the requirements of the national soil detailed investigation laboratory, the laboratory undertaking the detailed soil investigation must have a certain number of instruments and equipment, such as spectrophotometer, inductively coupled plasma emission spectrometer, atomic fluorescence spectrometer, microwave digestion instrument, Soxhlet extractor, Gas chromatography-mass spectrometry,
etc.

 

　　Clear waters and lush mountains are invaluable assets.
We will fight the tough battle of pollution prevention and control in depth, and the instruments and meters will escort them in many aspects
