The reporter learned from the recently held national conference on eco-environmental protection that in 2022, the construction of beautiful China was solidly promoted, the discharge of major pollutants in the country continued to decline, the goal of improving eco-environmental quality was successfully completed, and the eco-environmental protection work achieved hard-won new results.
According to the Ministry of Ecology and Environment, in 2022, 25 new cities across the country were included in the scope of clean heating support in the northern region, and the ultra-low emission transformation of 210 million tons of crude steel production capacity and the rectification of more than 46,000 outstanding volatile organic compounds were completed. We will continue to investigate and rectify the sewage outlets of the Yangtze River, the Yellow River and the Bohai Sea into the sea, start the investigation and evaluation of the pollution situation of mines left over from the history of the Yellow River Basin, promote the remediation of black and odorous water bodies in county towns and county-level cities, delimit township-level centralized drinking water source protection zones, and implement actions to improve the water quality of rivers entering the sea. Carry out actions to prevent and control the source of heavy metal pollution such as cadmium in agricultural land soil. Environmental improvement in 16,000 administrative villages has been completed nationwide. The construction of a "waste-free city" was launched in an all-round way, and 14 new pollutants were included in the key control list.
According to reports, in the past 10 years, China has continued to fight the defense of blue sky, clear water and pure land, and the prevention and control of pollution has advanced in depth, and the improvement of ecological environment quality has achieved remarkable results. The average concentration of PM2.5 in key cities in China decreased by 57%, and the concentration of PM2.5 in cities at prefecture level and above fell below the first-stage transition value of 35 μ g/m3 determined by WHO for three consecutive years from 2020 to 2022. In 2022, the proportion of days with excellent air quality in cities at prefecture level and above reached 86.5%, making China the country with the fastest improvement rate of air quality in the world.
In the past 10 years, the proportion of excellent surface water quality in China has increased by 23.8 percentage points, reaching 87.9%, which is close to the level of developed countries. For three consecutive years, the main stream of the Yangtze River reached Grade II water quality, and the main stream of the Yellow River reached Grade II water quality for the first time. The proportion of excellent water quality in coastal waters nationwide increased by 17.6 percentage points. Black and odorous water bodies are basically eliminated in the built-up areas of cities at prefecture level and above. In the past 10 years, China has successfully achieved the goal of "zero import" of solid waste, effectively controlled the environmental risks of soil and groundwater, and significantly improved the rural ecological environment.
The Ministry of Ecology and Environment said that the prevention and control of environmental pollution will be further promoted in 2023.
Promote the blue sky defense war-promote the construction of environmental infrastructure such as natural gas pipeline network, promote clean heating in the northern region in an orderly manner according to local conditions, promote ultra-low emission transformation and comprehensive treatment of key industries, carry out in-depth treatment of volatile organic compounds, deepen joint prevention and control of air pollution in key areas, and implement the noise pollution prevention and control action plan.
Promote the defense of clear water-promote the pilot project of water ecological assessment in the Yangtze River basin, comprehensively implement the rectification of tributaries entering the Yellow River, organize the rectification of black and odorous water bodies in cities (including county towns), consolidate and improve the level of drinking water safety, and comprehensively strengthen the supervision of mariculture, marine engineering, marine dumping and marine garbage.
Promote the battle of defending the pure land-strengthen the implementation effect of major projects to control the source of soil pollution, strengthen the control of soil pollution in production enterprises and closed relocation enterprises, delimit key areas for groundwater pollution prevention and control, and continue to promote rural environmental improvement. Strengthen the treatment of solid waste and new pollutants, further promote the high-quality construction of "waste-free cities", further promote the reform of strengthening the supervision, utilization and disposal capacity of hazardous wastes, start the pilot project of new pollutant treatment, and carry out in-depth prevention and control of heavy metal pollution in key industries.
