Deodorants are an important key element for qualified exhaust emissions:

Due to the complexity and difficulty of haze management, achieving a fundamental improvement in air quality will be a gradual process led by the government, supported by technology, implemented by enterprises, regulated by the market, and participated by the entire population.

Where does haze come from? How to manage haze? Why is the overall air quality improving, but our perception is not obvious? On March 1st, relevant experts pointed out that composite pollution leads to a decrease in environmental capacity, and pollution emissions are the internal cause of haze formation. Climate conditions are the external cause of haze formation. Therefore, specialized deodorants for spray towers and industrial structural adjustments are decisive factors in controlling haze.

Composite pollution leads to a decrease in environmental capacity, and pollution emissions are the internal cause of haze formation. The origin of PM2.5 includes direct emissions (primary source) and secondary generation (secondary source). The secondary generation of PM2.5 refers to the conversion of gaseous pollutants emitted into the atmosphere into fine particulate matter such as sulfates, nitrates, ammonium salts, etc. through various chemical and physical processes. Although some pollution sources have low concentrations of primary particulate matter, they produce many secondary particulate matter, becoming an important source of urban PM2.5. He Hong and his research team found that in the central and eastern regions of China, the contribution rate of secondary particulate matter to PM2.5 is often as high as 60%, and the proportion of secondary particulate matter is often higher during haze formation. However, there are still many unclear aspects regarding the mechanism of secondary particle formation at present.

To achieve long-term and stable improvement of air quality, targeted management of atmospheric haze needs to be strengthened, striving for precise control of haze. Firstly, leverage technological support to strengthen collaborative emission reduction of multiple pollutants. Secondly, first tier cities should prioritize the control of motor vehicle exhaust pollution. In addition, specialized deodorants for spray towers should increase efforts to prevent and control air pollution in northern China during autumn and winter, and vigorously prevent and control seasonal haze pollution caused by the burning of scattered coal and straw in rural and urban-rural areas.

Where does haze ultimately come from? How does atmospheric haze occur? How to control it? On March 1st, experts from the strategic pilot project of "Tracing and Controlling Atmospheric Haze" introduced the results and development of the relevant research. The research results indicate that overall air quality is improving, but compound pollution offsets the management role, and energy and industrial structure adjustment are decisive factors in haze control. This project was launched in 2012 and focused on the generation, evolution, and manipulation of PM2.5, with key areas such as the Beijing Tianjin Hebei region, the Yangtze River Delta, and the Pearl River Delta as the focus for discussion.

Climate conditions are the external cause of haze formation. The occurrence of climate characterized by low wind speeds and temperature inversion increases the probability of haze occurrence. Data statistics show that in the past 40 years, the annual average wind speed in the Beijing Tianjin Hebei region has been decreasing year by year, with a decrease of 37%. The frequency and wind speed of northerly winds, which are beneficial for the diffusion of pollutants in the region, have significantly decreased. In addition, PM2.5 emitted into the atmosphere inevitably leads to a decrease in surface temperature, while the absorbent substances in the upper layer of particulate matter will increase the temperature of that layer of atmosphere, forming a stable atmospheric structure of cold below and hot above, weakening air convection and further exacerbating pollution-- Deodorant manufacturer
