The "near thirsty" trapped by the Northern Shaanxi Nenghua Base is solved

The five-year exploration of groundwater resources in the energy and chemical industry base in northern Shaanxi has finally reached the end. The total amount of water resources that can be used each year is 1.365 billion cubic meters, which can fully meet the water demand of the chemical industry base during the “Twelfth Five-Year Plan” period. For the northern Shaanxi energy and chemical industry base that is being developed on a large scale but water shortages, the thirst for thirst will be eased. This is the information that the reporter learned at the review conference of the groundwater exploration results of the Northern Shaanxi Energy and Chemical Industry Base held in Xi’an on December 19.
The groundwater resources exploration project of the Northern Shaanxi Energy and Chemical Industry Base started in 2004 and was carried out by the China Geological Survey of the Ministry of Land and Resources and the People's Government of Shaanxi Province. The Shaanxi Provincial Department of Land and Resources and the Xi'an Geological Survey Center of China Geological Survey organized and implemented the project. Industrial water resources exploration and evaluation conducted by the provincial and ministerial departments.
Zhang Mao, head of the Xi'an Center for Geological Survey Water Division, introduced that based on traditional exploration technologies such as hydrogeological drilling and hydrogeophysical exploration, the use of advanced technologies such as GPS, satellite remote sensing, remote telemetry, and artificial earthquakes will enable the surveyors to The groundwater resources of the North Energy and Chemical Industry Base conduct comprehensive and systematic high-precision surveys and evaluations. The system has ascertained the conditions for the occurrence of groundwater, the total amount and distribution of water resources, and proposed countermeasures for the development, utilization, and protection of water resources, providing the planning for the energy and chemical bases. Important reference. The survey results show that the total available water resources in the region is 1.365 billion cubic meters per year, of which the groundwater utilization is 1.035 billion cubic meters per year and the surface water availability is 651 million cubic meters per year (the two are duplicated 321 million cubic meters. The current utilization of groundwater is 216 million cubic meters, and the annual potential for utilization is 8.19 cubic meters.
It is understood that the shortage of water resources is a bottleneck in the development of the energy and chemical industry base in northern Shaanxi. The current annual water consumption in the region is 112 million cubic meters, and the gap is 273 million cubic meters. The water demand for some large-scale and extra-large chemical projects cannot be met. Zhang Hongtao, Chief Engineer of the Ministry of Land and Resources, and Wang Zheng, Director of Shaanxi Provincial Department of Land and Resources, said that according to the results of the survey, the existing total water resources can fully meet the “Eleventh Five-Year” and “Twelfth Five-Year Plan” plans for energy and chemical bases in northern Shaanxi Province. Demand and base water shortages will be solved.
Relevant experts reminded that although the energy and chemical industry bases in Northern Shaanxi are relatively rich in water resources, the ecological environment in this area is relatively fragile. The spatial distribution of water resources is uneven and the dynamic changes are large. It is necessary to cherish resources, moderately exploit, and orderly use. At the same time, water-saving technology should be adopted to increase the intensity of sewage treatment and improve the reuse of water resources.
Linkage The national-level energy and chemical industry base in northern Shaanxi covers Yulin City and Yan'an City in Shaanxi Province, north of 36 degrees north latitude. It is rich in coal, oil, natural gas, rock salt and other mineral resources and is known as China’s “Kuwait”. The groundwater resources exploration area of ​​Northern Shaanxi Energy and Chemical Industry Base is located in the core area of ​​Northern Shaanxi Energy and Chemical Industry Base north of 38 degrees north latitude. It covers 5 counties (districts) of Fulin City Fugu, Shenmu, Fuyang, Jiaxian and Hengshan with a total area of ​​22604 square meters. km.
Northern Shaanxi is located on the edge of the Loess Plateau and the Mu Us Desert and belongs to arid and semi-arid climates. The lack of precipitation, large evaporation, fragile ecological environment, and shortage of water resources have become the bottlenecks that seriously restrict the construction and development of the base. According to the Yulin City Water Resources Plan, Yulin City's social water requirements in 2010 and 2020 were 1.457 billion cubic meters and 1.994 billion cubic meters, respectively, which were 445 million cubic meters and 7.1 million cubic meters of water respectively. With the acceleration of the pace of construction of energy and chemical bases, some large-scale and extra-large-scale projects have been started one after another. Industrial water consumption has grown rapidly, and chemical bases are facing severe “thirst” difficulties.
