[ Focus on Chemical Machinery Equipment Network ] Asia Clean Air Center today released the latest report "Atmospheric China 2021: China's Air Pollution Prevention and Control Process" at the "2021 China Blue Sky Observation Forum"
.
The report shows that China's overall air quality has achieved 7 consecutive upgrades, and "reaching the standard" has become the main theme, and it has achieved outstanding results among Asian developing countries

Chemical machinery and equipment network hotspots pay attention to chemical machinery and equipment.
The report shows that China's overall air quality has achieved 7 consecutive upgrades, and "reaching the standard" has become the main theme, and it has achieved outstanding results among Asian developing countries
.
The report shows that since 2013, China's air quality has been significantly improved for seven consecutive years.
In 2020, the annual assessment concentration of six pollutants nationwide has achieved full compliance, and the number of air quality compliance cities has also increased to 202
.
Among them, in 2020, the national average annual concentration of PM2.
5 will drop to 33μg/m3, which has entered China's national standard compliance line.
In recent years, ozone, which has been on the rise, has achieved a year-on-year decrease in its annual evaluation concentration in 2020

Air pollution and climate change have the same roots, and pollution reduction and carbon reduction can be synergistic.
The air pollution control measures since 2013 have allowed the public to harvest more blue sky and brought considerable carbon reduction effects

The air pollution control measures since 2013 have allowed the public to harvest more blue sky and brought considerable carbon reduction effects
.
In recent years, due to rapid economic development, the phenomenon of urban compound air pollution has intensified
.
The main sources of compound pollution are: productive pollution, such as harmful substances emitted by fuel combustion, smoke and dust, sulfur dioxide and other harmful gases produced by coal consumption in living stoves and heating boilers; transportation pollution, such as motor vehicle exhaust
.
Therefore, air pollution control is imperative, and related equipment is indispensable

Therefore, air pollution control is imperative, and related equipment is indispensable
.
In order to strengthen the monitoring and control of air pollution, China has established 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, and VOCs (volatile organic compounds).

.
In addition, for productive pollution, a continuous flue gas emission monitoring system can be used, including gas analyzers; particulate matter analyzers; temperature, pressure, flow rate monitors and other instruments and equipment
.
Suitable for continuous monitoring of exhaust gas emissions from various boilers, continuous online monitoring of particulate matter concentration, sulfur dioxide (SO2) concentration, nitrogen oxide compound (NOX) concentration, oxygen (O2) content, flue gas temperature, flue gas pressure, flue gas flow rate , Can also increase the measurement of carbon monoxide (CO), carbon dioxide (CO2), hydrogen chloride (HCL), hydrogen fluoride (HF), ammonia (NH3), hydrocarbons (CHX), humidity and other parameters

In view of transportation pollution, the use of relevant instruments and equipment to detect motor vehicle exhaust is a very important means to control motor vehicle exhaust pollution
.
Vehicle Emission detector is the instrument for the vehicle exhaust condition (concentration) is detected, are: automotive exhaust gas tester, diesel exhaust gas analyzer and other equipment

How to promote the development of high-end scientific instrument industry like mass spectrometer? It is hoped that the “one industry, one policy” approach can be adopted to support the development of the high-end scientific instrument industry in many ways
.
It can focus on supporting industry-leading enterprises, deepen cooperation with scientific research institutions and institutions of higher learning, and open up the industrial chain and innovation chain through "government-industry-university-research funding" collaboration, and build a high-end scientific instrument industry innovation base that gathers advantageous resources
