Fight the battle to defend the blue sky
Recently, the "Action Plan for Continuous Improvement of Air Quality" was issued, which is the third national action plan to defend the blue sky after the "Ten Atmospheric Measures" in 2013.
The plan calls for coordinated promotion of carbon reduction, pollution reduction, green expansion, and growth, with improving air quality as the core, reducing heavily polluted weather and solving outstanding atmospheric environmental problems around the people, and reducing fine particulate matter (PM25) Concentration as the main line, vigorously promote the emission reduction of nitrogen oxides and volatile organic compounds (VOCs), carry out regional coordinated governance, combine research and planning the path of air pollution prevention and control from near and far, and solidly promote the green and low-carbon transformation of industry, energy and transportation.
It is estimated that by 2025, PM2 will be in cities at and above the prefecture level across the country5. The concentration will be reduced by 10% compared with 2020, the proportion of days with severe pollution and above will be controlled within 1%, and the total emissions of nitrogen oxides and VOCs will be reduced by more than 10% compared with 2020.
pm2.5
pm2.5（partoculate matter 2.5) i.e. fine particulate matter, which refers to a diameter of 2Particulate matter below 5 microns (smaller than 1 20 the thickness of a human hair), also known as particulate matter that can enter the lungs, is mainly used in industrial production, automobile exhaust emissions, coal combustion, construction dust, catering fumes, etc. Its diameter is small, the area is large, the surface is easy to carry toxic and harmful substances, can be suspended in the air for a long time, and can also be transported across thousands of kilometers, which is extremely harmful to human health and air quality.
Nitrogen oxides
Nitrogen oxides (NOx) is a class of compounds generated by nitrogen and oxygen under high temperature combustion conditions, mainly in fossil fuel combustion, industrial production, etc., common nitric oxide (NO), nitrogen dioxide (NO2) and nitrogen oxides (N2O), easy to cause respiratory problems, induce cardiovascular disease, interfere with the immune system, and also bring acid rain, photochemical pollution and other environmental problems.
vocs
VOCs (volatile organic compounds) are volatile organic compounds, which generally refer to organic compounds that can participate in atmospheric photochemical reactions, or organic compounds that are measured or calculated according to the prescribed methods, mainly in fuel combustion, transportation, coatings, tobacco, textiles, furniture and other industries. It is volatile, and generally has the characteristics of toxicity, irritation, teratogenicity and carcinogenicity.
The Action Plan for Continuous Improvement of Air Quality has put forward corresponding goals in optimizing the structure of industry, energy and transportation, strengthening non-point source pollution control, reducing multi-pollutant emissions, strengthening mechanisms and capacity building, improving the system of laws, regulations and standards, and implementing the responsibilities of all parties.
Hanwei's solution helps air quality monitoring and governance
It is worth noting that relevant enterprises, parks and regulatory authorities have made significant concerns about PM25. The detection, monitoring and treatment of nitrogen oxides and VOCs are inseparable from various fixed portable detectors and comprehensive solutions with sensors as the core sensing elements.
Hanwei Atmospheric Monitoring Sensor Solution (Swipe to view).
In terms of sensors, Hanwei Technology Group launchedSensor solutions for atmospheric monitoring, including general-purpose atmospheric monitoring module, photoionization PID sensor, all-in-one detection module, electrochemical module, PPB-level ozone sensor and other sensor module products, can be PM25. PM10, CO, SO2, NO2, O3, VOCs, benzene, toluene, vinyl chloride, etc., which can be widely used in various fixed portable monitoring instruments, as well as petrochemical, iron and steel metallurgy, coatings, fugitive emission of pollutant gases in industrial plants, emergency monitoring, urban atmospheric environment and other scenarios.
In terms of monitoring and supervision solutions, Hanwei Technology Group has launched precise atmospheric environment supervision solutions and ultra-low emission measurement and control solutions. Among them,Solutions for precise supervision of atmospheric environmentCombine the use of various types of IoT sensing terminals, such as grid air quality monitoring stations, unorganized dust monitoring systems, catering fume monitors, odor monitors, VOCs monitoring systems, portable air quality monitors, etc., to build an intelligent supervision platform, which can realize the protection of urban air, industrial enterprises, Precise monitoring and fine management of air pollution in industrial agglomeration areas, monitoring and early warning of toxic and harmful gases in industrial parks, accurately tracing the source of heavily polluted areas and emission sources, and providing effective support for scientific research and decision-making.
Ultra-low emission measurement and control solutionsThe application of a series of intelligent perception terminals, the integration of the Internet of Things, big data, artificial intelligence technology, through the comprehensive management of organized and unorganized emission control and clean transportation of bulk materials and products, to build an integrated platform for the measurement, management, control and treatment of ultra-low pollutants, for steel, coking, cement and other heavy industry enterprises to provide whole-process environmental management, systematic environmental governance, improve the level of refined management and green environmental performance, and promote the transformation and upgrading of enterprises and high-quality development.
In terms of governance schemes, Hanwei Technology Group has matureVOCs control and odor gas treatment solutionsRelying on core technologies such as regenerative high-temperature oxidation catalytic oxidation (RTO RCO) technology, adsorption and concentration combined oxidation technology, solvent technology, and biological deodorization technology, the relevant solutions can provide one-stop services from design, construction, treatment to operation and maintenance for enterprises in coating, petrochemical, packaging and printing, pharmaceutical, electronics, hazardous waste treatment and other industries, and have many successful implementation cases across the country.

Air pollution is a typical tragedy of the commons, in order to prevent the tragedy from happening, China has abandoned the Western model of "pollution first and then treatment", adhering to the principles of protection first, prevention first, comprehensive treatment, etc., and has continuously issued relevant documents in legislation, standard setting, supervision and other aspects. Hanwei Technology Group will give full play to the scientific and technological power of IoT sensing terminals and intelligent platforms to help the supervision and governance of air pollution in China and the green and low-carbon development of various industries.
