In 2023, the air quality in Dongguan will improve significantly, and the proportion of good days will be 888%, an increase of 8 from 20228 percentage points, ranking first in the province in terms of improvement; The composite air quality index is 314, ranked 19th among 168 key cities in the country, and ranked 2nd among 15 "double thousand" cities; Achieve the elimination of heavily polluted weather throughout the year; pm2.5. PM10, SO2, NO2 and CO five air pollutants have stably reached the national air quality secondary standard, of which PM25 The average concentration was 21 micrograms cubic meters, which continued to meet the World Health Organization's second phase target value.
Behind this beautiful report card is the result of the joint efforts of all departments at all levels and all citizens of the city. The Dongguan Municipal Bureau of Ecology and Environment adheres to scientific pollution control, precise pollution control, and pollution control in accordance with the law, and has researched and issued the "Dongguan 2023 Action Plan for Continuous Improvement of Air Quality", coordinated the promotion of pollution reduction and carbon reduction, carried out various key measures, and paid close attention to the governance of key areas such as industrial sources, mobile sources, and non-point sources, and went all out to fight the battle to defend the blue sky.
Promote structural optimization and adjustment
Guide more than 400 enterprises in key gas-related industries such as furniture manufacturing, packaging and printing, electronic manufacturing, rubber and plastics, and footwear to implement the substitution of raw and auxiliary materials with low VOCs content, promote the construction of 2 centralized spraying centers and 2 sheet metal spraying sharing centers, and continue to dynamically clear "scattered and polluted" enterprises. Vigorously promote the use of new energy taxis, sanitation vehicles, official vehicles, etc40,000 units; Accelerate the elimination of old vehicles and non-road mobile machinery, and promote about 130,000 China III diesel vehicles were phased out ahead of schedule, and non-road mobile machinery with national I emission standards was basically eliminated, and a number of traffic congestion points were treated.
Strengthen the treatment and emission reduction of boilers and kilns
Promote the full implementation of special emission limits for natural gas boilers in the city, tighten the emission limit standard for nitrogen oxides to 50 micrograms, and upgrade 1,054 gas boilers. Key industries such as glass and waste incineration have carried out investigation and remediation according to ultra-low emission or in-depth treatment requirements to further reduce nitrogen oxide emissions.

Implement in-depth VOCs governance actions
Implement the grading and evaluation system and differentiated management and control of VOCs-related enterprises, complete the grading evaluation of 321 VOCs-related enterprises, and promote 187 enterprises to compile VOCs in-depth governance manuals and complete problem rectification. A comprehensive investigation was carried out on 1,467 organic liquid storage tanks in the city, and all 7 high-quality oil terminals of 10,000 tons and above in the city have completed oil and gas treatment. We will continue to carry out in-depth inspections on air pollution prevention and control, and promote nearly 2,000 enterprises to rectify gas-related problems.
Strengthen the governance of mobile sources
Improve the integrated supervision system of "heaven, earth, people and vehicles", complete the expansion of 6 sets of remote sensing monitoring and the construction of 10 sets of smoky vehicle capture systems, and comprehensively use remote sensing monitoring, remote monitoring, big data analysis and application and other means to strengthen the supervision of motor vehicles and non-road mobile machinery in an all-round way. Carry out road inspections, road inspections, and household inspections on a regular basis, and investigate and deal with nearly 5,000 smoky vehicles, vehicles with excessive exhaust gases, and unqualified vehicles in the annual examination. Strengthen the supervision of the whole chain of refined oil, coordinate and link multiple departments such as ecological environment, development and reform, public security, and market supervision, severely crack down on the illegal storage, transportation and sales of refined oil, destroy more than 200 "black oil" dens, and promote the use of direct oil products at 400 construction sites.
Strengthen the prevention and control of non-point source pollution
Comprehensively strengthen the prevention and control of dust pollution at construction sites, roads, and bare ground, implement dust monitoring at construction sites, and inspect all kinds of construction sites on site220,000 times, and more than 1,300 times to remediate problem sites. Strictly manage the closed transportation of mud trucks, improve the level of road cleaning at all levels in the city, and increase the frequency of road sprinkler fog cannons according to the early warning of air pollution. Comprehensive use of manual inspection, drone cruise, monitoring and other "civil air defense + technical defense" means to improve the level of open burning, open barbecue supervision.
Strengthen the response to polluted weather
Use the automatic atmospheric monitoring network to strengthen air quality monitoring and early warning. Dynamically update the list of pollution sources and emergency lists, in-depth and accurate grasp of the city's base information, and accurately formulate emission reduction measures. Strengthen the research and analysis of the pollution process, implement precise policies according to different meteorological conditions, and organize 96 polluted weather response actions in accordance with the requirements of "preventing the heavy and grabbing the light", and the number of polluted days has been reduced by 32 days year-on-year.
In 2023, the overall air quality of Dongguan will improve significantly, but air pollution control is long-term, arduous and complex. With the further recovery of economic and social activities, the prevention and control of air pollution is facing a severe test.
In 2024, Dongguan will thoroughly implement the national and provincial decisions and arrangements on air pollution prevention and control, vigorously promote the reduction of nitrogen oxides and volatile organic compounds, strengthen regional coordinated governance and prevention and control of pollution sources, continue to promote the green and low-carbon transformation of industry, energy and transportation, improve air governance capabilities, promote the continuous improvement of air quality in Dongguan, and strive to achieve a win-win situation of environmental, economic and social benefits.
