A few days ago, the Ministry of Ecology and Environment held a regular press conference in August. Zou Shoumin, Director of Science, Technology and Finance Department of the Ministry of Ecology and Environment, attended the conference and introduced the situation of science and technology helping ecological environment protection and high-quality development. Liu Youbin, spokesperson of the Ministry of Ecology and Environment, presided over the press conference, informed the recent progress of key work on ecological environmental protection, and jointly answered questions from reporters.
We sorted out and analyzed the information about air pollution, hoping to attract more attention and find new ideas to solve the air pollution problem.
Synergistic control of three axes by PM2.5 and ozone
At the press conference, a reporter asked about the work, public relations achievements and further plans in supporting ozone pollution and PM2.5 coordinated prevention and control by science and technology in recent years. Director Zou Shoumin answered around three aspects.
First, strengthen scientific research and lay a solid foundation for scientific pollution control.Through scientific and technological research and subject research, the formation mechanism of ozone pollution has been gradually proved, the understanding of the causes and influencing factors of ozone pollution has been further deepened, and the coordinated prevention and control ideas and pollution reduction strategies of PM2.5 and ozone pollution have been put forward.
The second is to adhere to the scientific and technological guidance and improve the precise prevention and control system.A comprehensive three-dimensional monitoring system of ozone and its precursors has been gradually formed, and short-term accurate forecasting and medium-and long-term trend forecasting have been basically realized. Modern scientific and technological means have been fully utilized to effectively integrate multi-source regulatory data such as satellite remote sensing and automatic monitoring. Through collaborative analysis of big data, the accuracy of problem clue identification has been greatly improved.
The third is to strengthen scientific and technological assistance to help local scientific decision-making and precise policy.Organize the implementation of the "one city, one policy" stagnation tracking research on coordinated prevention and control of PM2.5 and ozone pollution, and send 52 expert teams to 54 cities in Beijing-Tianjin-Hebei and surrounding areas, Fenwei Plain, and the junction of Jiangsu, Anhui and Lu Yu to conduct stagnation tracking research and technical assistance and guidance.
Carry out in-depth scientific and technological assistance,Help local and enterprises to scientifically control pollution according to law.
In recent years, the Ministry of Ecology and Environment has attached great importance to scientific and technological assistance, established a national comprehensive service platform for the transformation of scientific and technological achievements in ecological environment, and organized and carried out "one city, one policy" stagnation point tracking research in key regional basins, constantly summing up experience, optimizing and perfecting it, and through various modes such as "one city, one policy" stagnation point tracking research, "one thing, one discussion" scientific and technological consulting service, and "one topic, one training" technical training, it has laid a solid battle for pollution prevention and control for localities and enterprises.
Environmental protection industry becomes a strategic emerging industry.andNew economic growth point
In terms of the development of environmental protection industry, Zou Shoumin believes that China’s environmental protection industry has made great progress in recent years, providing an important guarantee for deepening the battle against pollution.
First, the scale of the environmental protection industry has continued to expand, and its contribution to the national economy has gradually increased.In 2021, the operating income of the national environmental protection industry was about 2.18 trillion yuan, an increase of 11.8% compared with 2020.
Second, the continuous transformation and application of new technologies and new achievements has strongly supported the battle against pollution.
Third, the environmental protection industry system and layout are more optimized.It covers pollution control and ecological restoration technology research and development, equipment manufacturing, design and construction, operation and maintenance, investment and operation, comprehensive consultation and other links.
Fourth, the service model of environmental protection industry is constantly innovating.Pollution third-party governance, environmental performance services, environmental stewardship and environmental financial services have shown a rapid development trend, and the PPP model has been gradually standardized. Next-generation technologies such as big data, cloud computing and Internet of Things are accelerating the infiltration and integration into the environmental protection field, which has improved the precision governance effect.
Scientific and technological progress is the key to promote air pollution control.
The conference repeatedly emphasized the role of science and technology, scientific and technological support in promoting air pollution control, from which we can easily see that scientific and technological progress is an important driving force to promote the development of air pollution control in a scientific and standardized direction, and it is also the development direction of air pollution control in the future, which is one of the reasons why Fossett Bio insists on biotechnology innovation.
Whether it is the coordinated control of PM2.5 and ozone or supporting local and enterprises to control pollution according to law, it depends on the development and progress of science and technology. In order to promote the development of related technologies, the Ministry of Ecology and Environment has also adopted science and technology projects as the leader to consolidate the foundation of scientific pollution control; Take scientific and technological achievements as the starting point to promote the deep integration of scientific and technological innovation and pollution prevention; Encourage all departments and enterprises to carry out scientific and technological innovation by means of innovative organization and cohesive efforts in pollution prevention and control.
With international advanced achievements,Help air pollution control
As a high-tech enterprise that has been committed to the research and development of compound biological enzyme for a long time, Fosai Bio has the international advanced level of FS compound biological enzyme research and development achievements, and has creatively applied this achievement to ozone pollution, PM2.5 pollution control, PM10 collaborative control, VOCs collaborative control and other air pollution control work, and achieved satisfactory results.
In the aspect of ozone pollution control, the biological enzyme ozone purifier generates O2 when combined with ozone, and the ozone purifier itself is oxidized into components that can be absorbed by plants. The biological enzyme components in the purifier can catalyze and accelerate this reaction, greatly improving the removal efficiency, and at the same time, it has the advantages of colorless, odorless, nontoxic and harmless, and does not produce secondary pollution. It is widely used in urban air control, industrial park and surrounding ozone exceeding the standard, and ozone pollution control in closed environment.
In the aspect of PM2.5 treatment, the active polymer components in the product have positive charge, which has a strong adsorption and coagulation effect, so that the small solid particles in the air are agglomerated and the liquid in the product condenses into small droplets to fall down, thus purifying the air. It is suitable for PM2.5 pollution control in urban atmospheric environment, industrial parks and surrounding open environments, and industrial environment workshops and workshops.
summary：Air pollution not only affects the days when the air is good, but also is the "culprit" that is potentially harmful to human health, and the influence of different pollutants on human health presents a phenomenon of 1+1 > 2. For example, in the same PM2.5 concentration environment and higher ozone environment, the harm of particulate matter to human body will also increase, and it is undoubtedly one of the important means to protect the people by using scientific and technological means.
