With the acceleration of industrialization and urbanization, air pollution has increasingly become one of the important factors restricting social and economic development and improving people's quality of life. Facing this challenge, it is particularly urgent to formulate and implement a scientific and reasonable air purification and environmental protection scheme. This paper will discuss how to build a perfect air purification system from three aspects: policy support, technological innovation and public participation.

First, strengthen policy support

The government should strengthen legislation, improve relevant laws and regulations, clarify air quality standards, and regularly evaluate the implementation effect. At the same time, more incentives and support policies will be introduced, such as tax relief or subsidies for enterprises that adopt clean energy; It provides convenient conditions for individuals to use low-carbon travel modes such as new energy vehicles. In addition, it is necessary to establish and improve cross-regional cooperation mechanisms, strengthen information sharing and technical exchanges between different regions, and jointly deal with regional air pollution problems.

Second, promote technological innovation

Scientific and technological progress is the key to solving environmental problems. The state should increase capital investment in scientific research institutions and enterprises to promote the research and development and application of air purification technology. Specifically, we can focus on the following areas:

High-efficiency filter materials: research and develop new high-efficiency filter materials to improve the removal rate of PM2.5 and other particulate matter.

Catalytic purification technology: using catalysts to reduce harmful gas emissions, such as NOx and SOx.

Intelligent monitoring system: establish a wide-ranging air quality monitoring network and collect data in real time for analysis and early warning.

Green energy conversion: promote the wide application of renewable energy such as solar energy and wind energy in industrial production and daily life.

Third, advocate universal action

Improving air quality is not only the responsibility of the government, but also the joint efforts of all sectors of society. Through various forms of publicity and education activities, citizens' awareness of environmental protection will be enhanced, and everyone will be guided to start from themselves and take practical actions to reduce pollutant emissions. For example, choose public transport instead of private cars; Actively participate in afforestation, garbage sorting and other activities; Support and purchase environmental protection products and services.

In a word, it is a long-term and arduous task to realize the fundamental improvement of air quality, which requires the government, enterprises and every citizen to work together and constantly explore and practice new methods and paths in order to finally achieve the goal. We have reason to believe that with the joint efforts of the whole society, the sky in China will be more blue and clear in the future!
