China News Network, Taiyuan, April 10 (Reporter Li Xinsuo) to defend the blue sky and breathe freely. Taiyuan, Shanxi, held a press conference on the 10th to announce the idea of improving the air quality of this energy capital city: reducing coke and controlling steel to ban cars.
Sun Jianxing, director of the Taiyuan City Ecology and Environment Bureau Office, introduced that the local “Taiyuan City Winning the Blue Sky Defence Battle 2020 Decisive Battle Plan” (hereinafter referred to as the “Plan”), the goal is to remove ambient air from other counties (cities, districts) except Qingxu County The annual average concentration of quality sulfur dioxide has all reached the first-class standard of "Ambient Air Quality Standards".
"In the first quarter, the number of excellent days in Taiyuan urban area and above was 48 days, an increase of 6 days from the same period last year, but the number of heavy pollution days also increased by 3 days compared to the same period last year." Hou Xiaojiang, a member of the party group of the Taiyuan City Ecological and Environmental Bureau, said in the first quarter, Taiyuan The urban air quality composite index was 6.65, a decrease of 16.4% compared with the same period last year, ranking 9th among the 168 cities nationwide, and 7th among the “2 + 26” cities.
As a traditional energy city, coal coke smelting power was once the pillar industry here. The aforementioned "Plan" also launched targeted reduction coke, steel control, car control, and coal ban strategies.
Sun Jianxing introduced that Taiyuan will significantly reduce the total amount of air pollutant emissions through the four structural adjustments of industry, energy, transportation and land use.
"Relying on the construction of Qingxu Economic Development Zone, the shutdown and elimination of 4.3-meter machine coke ovens and clean heat recovery coke ovens will be completely shut down, and the total amount of pollutant emissions from the coking industry will be significantly reduced." Sun Jianxing said that Taiyuan will focus on the steel industry and be strong Promote ultra-low emission transformation. TISCO has completed the ultra-low-emissions transformation. Among them, the ultra-low-emissions transformation in the sintering link has reduced nitrogen oxides by about 5,000 tons, accounting for more than 20% of the total nitrogen oxide emissions of local industrial enterprises.
In addition, the local will continue to promote the management of loose coal. Official data shows that there are currently about 227,000 rural clean heating users in rural areas, and rural clean heating coverage reaches more than 80%, basically achieving full coverage in the plains.
Sun Jianxing said that Taiyuan will continue to promote clean heating reform this year, and strive to achieve a rural clean heating coverage of more than 85%. Through clean heating renovation and loose coal treatment, the average concentration of local sulfur dioxide decreased by 46.3% in 2018, and by 18.5% in 2019. The average concentration is close to the first-class air quality standard.
With the rapid growth of local motor vehicle ownership and the use of non-road mobile machinery, pollutant emissions have become an important source of local air pollution.
In this regard, Sun Jianxing said that on the basis of vigorously implementing the "transit rail", the local will realize the pure electrification of buses and the new energy of environmental vehicles, and at the same time fully complete the task of eliminating diesel trucks operating at the national level III and below emission standards issued by the state Establish a normalized working mechanism for diesel truck road inspection and inspection.
