With the rapid development of industrialization and urbanization, air quality has increasingly become the focus of social attention. In recent years, the Chinese government and all walks of life have attached great importance to the prevention and control of air pollution, issued a series of policies and measures, and achieved remarkable results. The purpose of this paper is to discuss the challenges and opportunities that air pollution is facing at present, and how to achieve more efficient environmental improvement through scientific and technological innovation in the future.

First, the current situation analysis

1. Significant achievements but arduous tasks

Since the implementation of the "Ten Atmospheric Articles" in 2013, the national PM2.5 concentration has dropped by more than 40% on average, and the decline in key areas such as Beijing, Tianjin and Hebei is more obvious. However, the phenomenon of exceeding the standard still exists in some areas, especially during the heating period in winter.

2. The trend of diversification of pollution sources is increasing.

In addition to industrial emissions, non-traditional pollution sources such as motor vehicle exhaust and construction dust have an increasing impact on air quality. In addition, ammonia nitrogen gas produced by agricultural activities is also one of the important factors that cause the increase of particulate matter.

Second, the main challenges faced

-Insufficient technological innovation: There is still much room for existing governance technologies in terms of cost control and efficiency improvement.

-Insufficient enforcement of laws and regulations: Although relevant laws and regulations are constantly improving, there is still a problem of poor supervision in the specific implementation process.

-Low public participation: Lack of broad social consensus and support is another major obstacle to promoting air pollution control.

Third, the future direction and strategy

1. Strengthen investment in scientific research and promote technological innovation.

Encourage universities, research institutes and enterprises to cooperate in the research and development of cutting-edge technologies, especially in the fields of new energy vehicles and clean production technologies, so as to improve the energy efficiency ratio and reduce pollutant emissions.

2. Improve the legal system and strengthen law enforcement supervision.

Establish stricter standards and norms to ensure the effective implementation of policies; At the same time, we will strengthen the punishment for illegal acts and form a powerful deterrent effect.

3. Enhance public awareness and build a pattern of co-governance.

Use the media platform to popularize environmental protection knowledge and guide consumers to choose a low-carbon lifestyle; Organize volunteers to participate in community cleaning actions and jointly safeguard a beautiful home.

IV. Conclusion

Air treatment is a long-term and complex systematic project, which requires the joint efforts of the government, enterprises and every citizen. Let's go hand in hand and write our own blue sky and white clouds story in this hopeful new era!
