With the accelerated development of society, industrialization and urbanization, air quality problems have become increasingly prominent and become one of the important factors affecting people's health and quality of life. In order to effectively cope with this challenge, it is particularly important to adopt scientific and reasonable air control measures and environmental protection settings. This paper will discuss how to improve air quality and build a more livable urban environment by optimizing allocation from the technical level.

I. Pollution Source Control

1. Industrial emission management: Strengthen the supervision of key industries such as steel, cement and other energy-intensive industries, promote the use of clean energy and energy-efficient equipment, and reduce the emission of harmful substances.

2. Vehicle exhaust purification: Encourage the use of new energy vehicles or low-emission vehicles, and regularly carry out maintenance and inspection on existing vehicles to ensure that they meet emission standards.

3. Prevention and control of dust in building construction: the closed operation mode is implemented, and technical means such as wet spraying and dust reduction are adopted to reduce the dust diffusion generated in the construction site.

Second, the installation of air purification facilities

1. Construction of urban green belt: increase the area of park green space, plant a large number of plants with strong carbon absorption capacity, and use the self-regulation function of natural ecosystem to purify the air.

2. Layout of negative ion generators in public areas: Install negative ion generators in crowded places such as schools and hospitals to improve indoor air quality.

3. Popularization of household air purifiers: It is advocated that residents should be equipped with high-efficiency filter-type air purifiers in their homes to ensure the breathing safety in their living space.

Third, the establishment of monitoring and early warning system

1. Perfect real-time online monitoring network: set up automatic air quality monitoring stations covering the whole city to realize automation of data collection and transmission, and provide basis for government decision-making.

2. Construction of information release platform: timely and accurately release AQI index (air quality index) to the public through official websites, mobile apps and other channels to guide the public to arrange outdoor activities reasonably.

3. Formulation and implementation of emergency plan: In view of the heavily polluted weather, emergency response measures such as traffic restrictions and factory shutdown should be taken in advance to reduce the harm caused by pollutant accumulation in the short term.

To sum up, air pollution control is a complex and long-term process, which requires the joint efforts of all sectors of society to achieve remarkable results. Each of us should enhance our awareness of environmental protection, actively participate in this "blue sky defense war" and jointly create a fresh and pleasant living space.
