In the 21st century, an era of rapid development, human society is enjoying the convenience and comfort brought by scientific and technological progress, but it is also facing increasingly serious environmental problems, among which air pollution is one of the most prominent problems. With the acceleration of industrialization and urbanization, a large number of pollutants are discharged into the atmosphere, which not only affects people's health, but also poses a serious threat to the ecological balance. Therefore, exploring an effective air purification scheme and building a clean and healthy living environment have become an important issue to be solved urgently in contemporary society.

First, the current situation analysis

At present, many parts of the world are suffering from different degrees of air pollution. Industrial waste gas, automobile exhaust and construction dust are the main sources. These pollutants contain a lot of harmful substances such as PM2.5, sulfur dioxide and nitrogen oxides. Long-term exposure to such an environment will increase the risk of respiratory diseases and cardiovascular diseases, and even lead to premature death. In addition, air pollution will aggravate the greenhouse effect, accelerate the global warming process, and bring irreversible effects to the earth's ecosystem.

Second, the purification ideas

Facing the global challenge of air pollution, we need to take comprehensive measures from multiple angles:

1. Source control: Strengthen the supervision of key industries (such as chemical industry, steel, cement and other industries), promote the use of clean energy and technology, and reduce pollutant emissions.

2. Technological innovation: encourage and support scientific research institutions and enterprises to develop efficient air purification technologies and products, such as using nano-materials to adsorb and remove tiny particles in the air; Develop more energy-saving and efficient urban ventilation systems.

3. Public participation: raise citizens' awareness of environmental protection and advocate a low-carbon lifestyle, such as choosing public transport, reducing the frequency of private car use and actively participating in afforestation and other activities.

4. International cooperation: In view of the cross-border characteristics of air pollution, it is particularly important to strengthen international cooperation and exchanges. By sharing data information and technical standards, we will jointly deal with regional and global air quality problems.

Third, look forward to the future

We have reason to believe that with the joint efforts of the whole society, the future sky will become more blue. Every individual is a force to change the world. When each of us takes action, we can gather into a powerful driving force to promote social progress. Let's go hand in hand and make unremitting efforts to realize the beautiful vision of "blue sky and white clouds"!

In a word, "Environmental Vision of Air Purification Ideas" is not only a technical discussion about improving air quality, but also a reflection of the values of pursuing the quality of life in the future. I hope that through continuous efforts, we can create a beautiful tomorrow in which man and nature coexist harmoniously.
