How does the city and state dynamics 丨 how to create a clear "Gobi Pearl" in Jiayuguan?

In the distant northwest, Yijiang Qingshui wind down from the Qilian Mountain and pass through Jiayuguan City to bring rare water vapor to this arid and rainy city. A lot of charm is added to Jiayuguan.

The "Display River", known as the mother River of Jiayuguan City, originates from the middle section of Qilian Mountain, Qinghai Province to dean Henan Mountain with a total length of 370 kilometers and flow through 32.08 kilometers of Jiayuguan. The only river water source of greening.

In recent years, Jiayuguan City has firmly established the concept of "green water and green mountains is the golden mountains and silver mountains". The major historical mission makes Laihe more full, clearer, and more beautiful.

Manage and control the sewage port, the sewage does not enter the river

Due to mining enterprises, the name of the enterprise, the name of the city, Jiayuguan City is the key project of the "Jiuquan Iron and Steel (Group) Co., Ltd. (hereinafter referred to as" Jiu Steel "during the national" 1st Five -Year Plan "plan and the" three -line "construction period. ) "Industrial cities developed by construction. In the early days of the city, deserts, Gobi, and factories constituted the main urban landscape.

Jiayuguan City is in steel, and the key to the governance of ecological environment is also in steel. During the steel production process, the opening of the mountain mining and pollutant emissions to the ecological environment of Jiayuguan City, especially the water environment brings a lot of pressure.

In this regard, Zhao Jianhui, deputy general manager of Jiu Gang Safety and Environmental Protection, said: "As a provincial -owned state -owned enterprise and national policies focusing on the metallurgical energy industry, we have a sober understanding of the shortcomings, key points, and difficulties of environmental protection. The arduous and long -term are also prepared. "

In recent years, Jiu Gang has completed a total of 573 million yuan to implement 14 water pollution treatment projects. In 2022, Jiu Gang further focused on "gas raising, water treatment, solidifying the soil, and strong ecology", and fascinated the pollution prevention battle.

Among the many environmental protection projects of Jiugang Group, the most representative is the wine steel sewage treatment plant that has been completed by environmental protection in June 2011.

The wine and steel sewage treatment plant is responsible for the production of wastewater in various plants in the wine steel metallurgical plant and the treatment of sewage in the urban area of ​​Jiayuguan. After years of operation and technological iteration, the wine and steel metallurgical factory area has now achieved "near -zero" emissions, and all of the recycled water are used for green irrigation and production of water.

"On this basis, Jiu Gang actively carried out the governance of the Laihe River, and invested more than 60 million yuan to implement the optimization and transformation of the mirror Tieshan Mine for drainage and sewage treatment systems." Zhao Jianhui said. This has greatly reduced the outer displacement and the concentration of pollutants, laying the foundation for the improvement of the water quality improvement in the Jiayuguan section of Laihe.

Strengthen sewage treatment and realize the entire process supervision

Water resources, water ecological health, and livable water environment are the inevitable requirements for implementing the construction of ecological civilization. It is the deserved meaning of building a happy and beautiful river and lake target. Essence And these are inseparable from a powerful sewage treatment system.

Since the "Thirteenth Five -Year Plan", the daily sewage discharge of urban and towns in Jiayuguan has increased year by year. However, with the increase in the construction and treatment standards of sewage treatment facilities, the removal rate of pollutants has increased significantly, and the major pollutants emissions have reduced the trend year by year.

In addition to the "near -zero" discharge of the wine and steel sewage treatment plant, Jiayuguan City has also built the distributed sewage treatment station of Jiayuguan Industrial Park, the Jiabei sewage treatment plant, the implementation of the urban sewage treatment plant bidding and reconstruction project, and the sewage pipe network in the area was built. The system is perfect. The full collection of industrial wastewater and domestic sewage is fully collected. The quality of the water out of the water has reached the first -level A standard.

In addition, Jiayuguan City relies on online monitoring and other means to comprehensively strengthen the supervision of sewage treatment facilities and surrounding water environmental problems.

Speaking of the focus of the future work, Zhang Fang, the Ecological and Environment Bureau of Jiayuguan City, told reporters, "We will insist on not setting up the river drainage port, continue to carry out inspections of dirt -draining ports, prevent illegal sewage, and form a long -term effect of effective supervision of the river drainage port. mechanism."

In addition, prevention and treatment of agricultural and rural pollution is also a key task to ensure water quality.

Zhang Fang told reporters: "In recent years, Jiayuguan City has passed the construction of rural sewage treatment stations, rural garbage clearance treatment, comprehensive utilization of livestock and poultry manure, agricultural film recycling, and improving pesticide fertilizer utilization. System governance. Rural sewage treatment rates reached 35%, rural garbage collection rates reached 100%, the supporting rate of pollution prevention facilities for large -scale livestock poultry farms reached 100%, agricultural membrane recovery rates reached more than 80%, pesticides and chemical fertilization utilization Rate 40%. "

Do a good job of "water articles", high people's livelihood

In Jiayuguan, the concept of "urban water interaction and human water harmony" can be seen everywhere.

Adhering to the "ecological market" strategy, Jiayuguan focuses on "water articles". Drimp to the city, water planting with water, and green city, and a 17 -seater reservoir has been built. The per capita water area is 27m2, and the green coverage rate reaches 40.7%.

In order to conform to the people's expectations for the happy rivers and lakes, the planning of Jiayuguan City first, in 2010, compiled the "Jiayuguan City Display Ecological Environmental Governance Engineering Planning Plan" in 2010, around the construction of the "Safety River, Ecological River, Landscape River, Culture, Culture The goal of River and Happiness River adopts the "Qinghong Division of Governance" governance mode, and according to the "Wetland Cultural Sports Area, Wetland Play Water Leisure Area, Greenland Science Popularization Education Area" and other nodes, build a "forest embankment from the outside to the inside The continuous natural ecological pattern of the beach water will be invited to the Laihe River into a happy river in the lake and mountains, the river of Hedao, the dependency of the forest water, and the park embellishment of the park. On this basis, the comprehensive management of the ecological environment governance project of Laihe Jiaguanguan to Jiajiu's boundary section was officially started in 2020. The main construction contents include planting soil backfill and greening pipeline laying.

To this day, Jiayuguan City has invested 1.28 billion yuan to comprehensively govern the Laihe River. In the past, the problem of the piles of sand and gravel was gone. In the first quarter, the first place of the national surface water assessment section was the first place.

On April 20, 2022, after the acceptance of the provincial acceptance team, the Laihe Jiayuguan section became the first demonstration rivers and lakes to pass the first batch of 4 pilots in the construction of the beautiful happy rivers and lakes in Gansu Province. Hearing this news, Hou Zengyi, director of the management department of Laihe Ecological Culture Scenic Area, was very excited, "this means that our governance work is effective."

"The current Daihe Jiayuguan section, the snow mountain is reflected, the water is clear, the scenery is pleasant, and the scenery is beautiful." A citizen told reporters excitedly. The ecological scrolls of "River Chang, Water Clear, Green, Jingmei, and People" are unfolding slowly in Jiayuguan ...
