Social and air pollution is becoming more and more serious, which not only affects human health, but also threatens ecological balance and sustainable development. Therefore, it is particularly important to establish a perfect and efficient air purification and environmental protection mechanism. This paper will discuss how to achieve this goal from three dimensions: technical means, policies and regulations and public participation.

First, technological innovation is the foundation

1. Green energy substitution: vigorously develop renewable energy sources such as wind energy and solar energy, and reduce pollutant emissions from fossil fuel combustion.

2. Research and development of efficient purification equipment: Encourage scientific research institutions and enterprises to increase investment and develop new air purification technologies and products, such as nano-filtration materials and biological purification technologies, so as to improve the efficiency of air quality control.

3. Construction of intelligent monitoring system: Using modern information technologies such as the Internet of Things and big data, a comprehensive environmental monitoring network is established to grasp the dynamic changes of pollution sources in real time and provide a basis for accurate policy making.

Second, strict laws and regulations are the guarantee.

1. Formulate and improve relevant laws: introduce or revise the air pollution prevention and control law and other relevant laws and regulations, clarify the responsibilities and obligations of all parties, and increase the punishment for illegal sewage discharge.

2. Implement the total amount control system: scientifically set the total amount indicators of major pollutants according to the regional environmental carrying capacity, and promote emission reduction through market transactions.

3. Promote cleaner production standards: guide and support industrial enterprises to adopt advanced and applicable technologies and processes, reduce waste gas generation, and promote industrial upgrading and transformation.

Third, the participation of the whole people is the key

1. Enhance civic awareness: Promote public awareness of the importance of air quality through education and publicity, and advocate a low-carbon lifestyle, such as using more public transport and driving less.

2. Support the activities of non-governmental organizations: The government should give more support to non-profit environmental protection groups, including financial assistance and information sharing, and play its role as a bridge to connect all sectors of society to participate in environmental protection.

3. Carry out volunteer service projects: organize volunteer teams to participate in activities such as urban greening and afforestation, and also participate in monitoring and reporting environmental pollution incidents to form a good social atmosphere.

In a word, facing the severe air pollution challenge, we need to take comprehensive measures to deal with it from multiple angles. Only when scientific and technological innovation, rule of law construction and people's actions are closely combined can we truly establish a sound and effective air purification and environmental protection system and make our sky bluer and brighter.
