Compared with the same period of the previous year, the number of days with good air quality increased by 10 Day, the excellent and good rate increased by 4.1 percentage points.” On September 1, a set of data released by the Liuyang Branch of the Changsha Municipal Ecological Environment Bureau once again revealed the good results of "Liuyang Blue".
Liuyang's air quality from January to August was 100%
Liuyang Daily News (Reporter Zhang Kefu, Correspondent Lai Yuanqing) "As of August 31, the number of days with excellent air quality was 157 days, 87 days with good air quality, and the excellent rate was 100%. Compared with the same period last year, the number of days with good air quality increased by 10 Day, the excellent and good rate increased by 4.1 percentage points.” On September 1, a set of data released by the Liuyang Branch of the Changsha Municipal Ecological Environment Bureau once again revealed the good results of "Liuyang Blue".
The continuous improvement of air quality benefits from scientific protection and governance. "Emissions reduction is the leading factor in air quality improvement." Dong Aizhong, full-time deputy director of the Liuyang Blue Sky and Clear Water Office, said that in the battle to defend the blue sky, Liuyang focused on four types of pollution sources: industrial sources, construction sources, mobile sources, and non-point sources. , To vigorously promote the two fronts of "control particulate matter and control ozone", reduce pollutant emissions from the source, and let the blue sky and white clouds permanent.
Boilers with dense smoke are a major air polluter, and coal-fired boilers are one of the main sources of particulate matter. In 2019, Liuyang comprehensively promoted boiler emissions reduction, completing the transformation of 31 sets of coal-fired boilers of 10 steam tons or more with special emission limits, 208 sets of coal-fired boilers of 10 steam tons and below, and 25 gas-fired boilers with low nitrogen.
Yangjia Paper, located in Hehua Street, is the first company in the city to complete the transformation of the special limit for coal-fired boilers of more than 10 steam tons. “Environmental protection facilities such as desulfurization, denitrification, and dust removal have been added, and boiler emissions have reached national standards,” said Hu Yong, chairman of the company. Changsha Xinben Pharmaceutical Co., Ltd., located in Xichong Town, transformed coal-fired boilers into biomass pellet boilers, reducing pollutants emissions by more than 50%.
In summer and autumn, the temperature rises and ozone becomes the primary air pollutant. How to treat ozone pollution? VOCs (volatile organic compounds) treatment is the key. Since the beginning of this year, Liuyang has promoted the use of low-volatility raw and auxiliary materials to 264 companies involved in VOCs, including furniture manufacturers. Compared with the beginning of the battle to defend the blue sky in 2018, the city's total VOCs emissions have dropped by more than 20%. For agriculture and daily life, non-point source pollution is diverse and difficult to control. In 2019, Liuyang promoted the return of broken grass to the field and the removal and utilization of 769,000 mu, and the phenomenon of open-air burning of straw was greatly reduced. This year, Liuyang also comprehensively promoted the transformation of the catering oil fume purification system in the canteens of 749 government agencies, enterprises and institutions in the city, so that there is nowhere to escape the cooking fume.
In the process of air pollution prevention and control, "departmental linkage" and "early warning mechanism" have played an important role. "For example, for ozone prevention and control, at 8 o'clock every morning, we will activate the early warning mechanism once the ozone concentration is found to be too high through actual measurement." Dong Aizhong introduced that after the early warning mechanism is activated, the Blue Sky Office, Park, Environmental Protection, Housing Construction, and Urban Management , The traffic police and various towns (sub-districts) and other departments and units acted quickly to reasonably arrange restricted traffic, restricted production, staggered production and increased frequency of sprinkling water to reduce dust, effectively preventing the formation of ozone.
The fineness of the ecological environment is related to the foundation for building a well-off society in an all-round way. In the next stage, Liuyang will take the opportunity of striving to create a national "green water and green mountains are the golden mountains and silver mountains" practice innovation base work as an opportunity to do a good job of blue sky, clear water and clean land, and contribute to the new victory of ecological civilization.
