On April 29, under the guidance of the Internet Information Office of the Shaanxi Provincial Party Committee of the Communist Party of China, the Internet Information Office of the Yan'an Municipal Committee of the Communist Party of China, the Internet Information Office of each county (city and district), the Western Decision-making Network, the Yan'an Financial Media Center, and the County (City, District) Financial Media Center, the "Catching Up and Surpassing the New Chapter, Adding Glory to the Future" network theme publicity and interview group came to Yanchang County, and jointly walked into the Industrial Park of Heijiabao Town and Luozishan Town of Yanchang County, and visited the sewage upgrading and transformation project of Oilfield Gas Chemical Technology Company and the ecological protection and restoration project of degraded ecosystems in northern Shaanxi.
Yanchang County is located in the hinterland of the Loess Plateau in northern Shaanxi and the west bank of the Yellow River. It has a long history and abundant products, and is the location of China's first onshore oil well, as well as the world's best eugenic area for melons and fruits, known as the "mother of oil, the hometown of melons and fruits, and the home of food".
Oilfield Gas & Chemical Technology Co., Ltd. is an important project of Yanchang Petroleum Group to optimize the industrial layout, improve the industrial energy level, and promote the extension of the fine chemical industry chain, and is also a scientific and technological demonstration project of green and low-carbon, circular economy, and comprehensive and efficient utilization of resources.
It is reported that the sewage upgrading and transformation project plans to build a new 80m3/h carbon black sewage pretreatment unit, a 4m3/h PT pretreatment unit, a 10,000m3 accident buffer tank and supporting facilities, and a 210m3/h advanced treatment unit and supporting facilities. and a new sodium sulfide dosing unit with a treatment scale of 80m3/h BOD detachant wastewater to remove excessive copper ions in BOD detachant wastewater, and a new sodium carbonate dosing device with a treatment scale of 700m3/h high-density clarifier for the hardening of high-density clarifiers of the existing water reuse station, as well as ancillary public works. The estimated cost of the project feasibility study approval is 93.8362 million yuan.
The project of restoration of degraded ecosystems and comprehensive control of soil erosion in northern Shaanxi (referred to as the "dual" project in 2023) Yanchang County is of great significance to improve the ecological environment, improve the quality of forest stands, and build Yanchang County into a green demonstration county with "beautiful mountains and rivers and ecological livability".
The total construction scale of the project is 115,000 mu, including 25,000 mu of artificial afforestation, 30,000 mu of degraded forest restoration, and 60,000 mu of mountain closure and afforestation, with a total investment of 48 million yuan, which is uniformly implemented by the Municipal Forestry Bureau. Construction will start on March 15, 2024, and is expected to be fully completed by May 1.
The project is divided into three modes: artificial afforestation, degraded forest restoration, and mountain closure and afforestation, and the degraded forest is restored by three restoration methods: "replanting + site clearing, replanting + thinning + site cleaning and thinning". At present, 24,000 acres of artificial afforestation, 26,000 acres of degraded forests have been restored, and 50,000 acres of mountains have been closed for afforestation. After the completion of the project, it will further expand the green territory of Yanchang County, improve the quality of forest stands, improve the management and protection of forest and grass resources and soil erosion control, and lay a solid foundation for winning the battle of "Jizi Bay" of the Yellow River.
