August is the hottest season of the year in Fujian, and the "ozone prevention and control" being carried out throughout the province is also very hot.
Take the lead in issuing ozone prevention and control guidelines, promote 120 provincial key emission reduction projects, and consolidate the foundation of pollution control and emission reduction … … Fujian started with the top-level design, played a combination boxing, treated the ozone with the right medicine, and made the blue sky defense war develop in a scientific and refined direction.
Strengthening the top-level design and paying attention to both the symptoms and the root causes
Fujian’s air quality has been excellent for a long time, ranking in the forefront of the country, and the overall ozone concentration has remained excellent, which is better than the national average. Why should we keep an eye on ozone? "You can’t take it lightly, or be lucky. You must plan ahead, make precise policies, and grasp ozone prevention and control like smog control." The relevant person in charge of the Fujian Provincial Environmental Protection Department said frankly.
The person in charge’s worries are not excessive. From 2014 to 2016, the average specific percentile concentrations of ozone in Fujian Province were 115&mu respectively; g/m3、111μ g/m3、115μ G/m3, which is generally excellent, is better than the national average. However, in 2017, under the effective control of PM2.5, due to adverse meteorological conditions and other factors, the ozone concentration in Fujian Province increased significantly, especially from April to November, which was a high-value period of ozone concentration in Fujian Province and became a prominent factor dragging down air quality.
Fujian Province is soberly aware that at present, ozone pollution control in various places is not strong enough, measures are not in place, the level of waste gas collection and treatment of VOCs-related enterprises is still low, and unorganized emissions are serious. At the same time, there are a certain number of "scattered pollution" enterprises in various places, with backward production technology and simple pollution control facilities, which are also important factors causing atmospheric environmental pollution.
The "Guidelines for the Prevention and Control of Ozone Pollution in Fujian Province (Trial)" was first issued in China. According to the characteristics of climate, topography and industrial structure in various places, it emphasized local conditions and the right medicine, and put forward the requirements of refined management in the whole process from source prevention, process control to terminal treatment.
Twelve departments, including Fujian Provincial Environmental Protection Department, National Development and Reform Commission, and Economic and Information Committee, jointly issued the Work Plan for Ozone Pollution Prevention and Control in Fujian Province, establishing and improving the working mechanism of ozone pollution prevention and control with clear responsibilities, division of labor and joint management, and proposing to establish and improve the ozone pollution prevention and control management system with improving ambient air quality as the core by 2020, and strive to reduce the total emission of VOCs by more than 10%.
In order to fill the shortcomings of the emission standards for volatile organic compounds (VOCs) of ozone precursors, Fujian Province has formulated three mandatory local standards for VOCs emission standards for printing industry, industrial painting process and industrial enterprises, which have been agreed by the provincial government and will be issued and implemented in the near future.
At the same time, Fujian Province has also listed ozone remediation as the focus of the "three-in-one" inspectors, namely, the feedback from the central environmental protection inspectors, the feedback from the provincial environmental protection inspectors and the inspection and notification of the responsibility book of the party and government leaders for ecological environmental protection. The problems of poor promotion, serious lag in the progress of rectification, superficial rectification, pretend rectification and perfunctory rectification are held accountable according to laws and regulations, and the responsibility of local party committees and governments for ozone pollution prevention and control is consolidated.
Implement 120 key emission reduction projects to promote precise governance.
Enterprises with large VOCs emissions such as petroleum, chemical industry, painting and shoemaking in Fujian Province, and enterprises with large NOx emissions such as thermal power (including thermal power and self-provided power stations), steel and flat glass are mainly concentrated in coastal areas, which is also an area with serious ozone pollution in Fujian Province.
Targeted prevention and treatment, the right medicine. All parts of Fujian Province cooperate to control VOCs and NOx for key pollution sources, focus on key industries and key enterprises, and promote ozone prevention and control to be precise, accurate and practical.
"Up to now, 50 precision management projects have been completed, and the emission reduction ratio has been 38%." Pointing to the schedule of atmospheric environmental precise control and emission reduction projects, the person in charge of the Atmospheric Department of Fujian Provincial Environmental Protection Department said that on the basis of reports from various places, the Provincial Environmental Protection Department screened out 120 provincial-level key precise control and emission reduction projects, and implemented regular scheduling, notification, early warning, supervision, interviews and other systems. According to preliminary statistics, these key projects can reduce VOCs emissions by nearly 10,000 tons and NOx emissions by more than 3,000 tons annually.
Fujian Province has also carried out intensive supervision of key areas in the province, strengthened law enforcement inspection of waste gas emission enterprises in key areas such as Zhangzhou City, Quanzhou City and Putian City, and created a strong offensive and high-pressure situation of law enforcement supervision. More than 2,000 enterprises involved in VOCs emission were inspected, and corporate environmental violations were severely investigated according to laws and regulations.
All localities closely follow the actual situation and implement rectification of key industries.
Fuzhou has optimized its industrial layout and prohibited the introduction of projects with serious pollution. Comprehensive treatment of VOCs in chemical, pharmaceutical, synthetic leather and other industries in Jiangyin Industrial Zone of Fuqing and Minhou Automobile City; Deepen the rectification of the iron and steel industry around Luoyuan Bay and reduce NOx emissions.
Xiamen has implemented rectification in stages by industry, and has started the third stage of rectification of four industries: shipbuilding and maintenance, rubber products, shoemaking and handicrafts.
Quanzhou has strict access to new reconstruction and expansion projects, and VOCs emissions are replaced by the same amount or times. At the same time, it will promote the treatment of VOCs in key industries such as petrochemical industry, industrial painting, packaging and printing, shoemaking, textile printing and dyeing, further improve the LDAR (LDAR) level of Quangang and Quanhui Petrochemical Park, and promote the environmental protection upgrading and transformation of industrial pot kilns.
Putian deepens the VOCs management of key industries such as shoe-making, packaging and printing, coatings, rubber, chemical fiber and furniture in urban areas; Promote environmental protection upgrades such as industrial boilers and kilns, and reduce NOx emissions.
Since mid-July, Zhangzhou has taken the standardized management of VOCs-related furniture enterprises as a breakthrough, enforced the law with an iron fist, promoted the closed operation of VOCs-related workshops of furniture enterprises to realize the complete collection and treatment of organic waste gas, regularly replaced waste activated carbon, and strictly implemented the standardized temporary storage and disposal of waste paint barrels, waste paint residue, waste activated carbon and other hazardous wastes.
Ningde focuses on prevention and control in Zhangwan area, and strengthens VOCs treatment in key industries such as battery manufacturing, industrial painting, packaging and printing in Zhangwan Industrial Zone to ensure the stable operation of treatment facilities; Promote waste incineration power generation, steel environmental protection upgrading, and reduce VOCs and NOx emissions.
