With the acceleration of society, industrialization and urbanization, the problem of environmental pollution has become increasingly prominent, especially the deterioration of air quality has posed a serious threat to human health and ecological environment. Faced with this challenge, national and local governments have introduced a series of policies and measures to effectively improve air quality. This paper will discuss the indispensable environmental protection elements in air treatment from several key angles.

First, source control-reducing pollutant emissions

Source emission reduction is one of the most direct and effective means to prevent and control air pollution. This includes strengthening the management of major emission points such as industrial sources, traffic sources and other sources of life, such as improving energy efficiency, promoting the use of clean energy, and implementing stricter vehicle exhaust emission standards. At the same time, it is necessary to intensify the investigation and punishment of illegal sewage discharge to ensure the effective implementation of laws and regulations.

Second, comprehensive governance-building a multi-governance pattern

The improvement of air quality requires the joint participation of all sectors of society. The government should play a leading role and make a scientific and reasonable planning scheme; Enterprises should actively fulfill their social responsibilities and adopt advanced technology and equipment to reduce emissions; The public also needs to enhance their awareness of environmental protection and practice a green and low-carbon lifestyle in their daily lives. In addition, encourage and support scientific research institutions to carry out relevant research and provide technical support for decision-making.

Third, monitoring and early warning-establish and improve the supervision system

It is very important to establish a perfect atmospheric environmental quality monitoring network to grasp the regional air quality in time. Through the combination of fixed site and mobile detection platform, all-round and all-weather monitoring is realized, and data information is released to the society regularly. When it is predicted that there may be heavy polluted weather, the emergency plan should be started in time and corresponding measures should be taken to reduce the impact.

Iv. international cooperation-sharing experience to promote global action

In view of the characteristics of cross-border transmission of air pollution, it is particularly important to strengthen international exchanges and cooperation. Countries can learn from each other's successful cases and technological achievements and work together to meet the challenges brought about by climate change. For example, China actively participates in multilateral negotiations under the framework of the United Nations, and works with other countries to promote the formation of a fair, reasonable, win-win global climate governance system.

In a word, air treatment is a systematic project, involving many fields and links. Only by adhering to the principle of treating both the symptoms and root causes and comprehensive policies can we fundamentally solve the problem of air pollution and give people a blue sky and white clouds.
