The water Diversion project in the Bohai Sea in Xinjiang is being questioned.

Core tip: According to the calculation of Wang Yuan, the project a total investment of 62.8 billion yuan, including construction costs of 56.7 billion yuan. The plan is to draw 365 million tons of seawater each year to achieve 4.7 billion economic benefits and a profit of 1.2 billion yuan per year.　　However, behind the feasibility report, the project still suffers from a lot of questioning at both the economic and technical levels.　　The grand idea of the water Diversion project in the Bohai Sea caused a controversy.　　The plan to introduce seawater into the desert has been reported, and many water experts and environmentalists in the country believe that the more than 60 billion water diversion project is not feasible at both the economic and technical levels, and compares it with the Three Gorges Dam and the controversial South-to-north water Diversion project.　　Costs and environmental protection are two of the main concerns of the project. But in response to the outside world, the project is responsible for Wang Yuan Sea Water Desalination Co., Ltd. in Inner Mongolia (hereinafter referred to as "Wang Yuan Company") but not, the company's chairman Wang Xiushun in an interview with this reporter said: "We will not do a loss of business." "It is understood that at present, the Inner Mongolia Development and Reform Commission and the Liaoning Provincial development and Reform Commission has targeted the project.　　According to Wang Xiushun, 5 sites involved in the project have been started.　　High energy consumption or high profit?　　According to the plan, "Sea west of the project will be taken from the northwest coast of the Bohai Sea to reach 1200 meters altitude, the way southeast of Inner Mongolia Autonomous Region, and then 42° line things in the direction of the WA trough surface, flowing through the Yanshan, Yinshan North, out of the Wolf Mountain to the west into the Yenhai, bypassing the horse-horse　　This means that the project will travel through four mountains, a lake, covering the eight deserts of western China.　　According to Wang Xiushun, the "West Sea" project is divided into two major stages, the first stage from the northwest coast of the Bohai Sea up to 1200 meters height, the entire process with a diameter of 3.2 meters of FRP pipe for conveying; the second part of the construction of the 320-kilometer-long underground tunnels, the sea water to the Inner Mongolia xilin Gol desalination plant.　　According to the calculation of Wang Yuan, the total investment of project one period is 62.8 billion yuan, of which the construction cost is 56.7 billion yuan.　　While construction costs account for most of the total investment ratio, experts say the cost of pumping energy is as much as the cost of desalination. "Large-area pumping requires strong power support, which is too much energy consumption, and now the state energy situation is so tense, unless we can draw on the experience of wind power and solar energy from similar projects abroad."　　Zhang Bo, Deputy Secretary-General of China Hydropower Engineering Society, said in an interview with our correspondent.　　In response to the high cost of pumping, Wang Xiushun said that in the pumping process, the project can make full use of the wind power resources in Inner Mongolia, and he further stressed that as the project progresses, solar energy will also be applied to the pumping system. "Wind power itself is not stable, it is impossible to rely on wind to complete such a large amount of pumping."　　"Zhang Bo said. In addition, in the desalination process, Wang Xiushun said it would make full use of local coal chemical enterprises and power plantsWaste heat, dilution and dilution of seawater. "Now coal chemical enterprises and power plants are only 37% of the thermal efficiency, in addition to the volatile parts, we can also use 50% of the residual heat, which can provide a part of the desalination process of energy consumption."　　"Wang Xiushun said.　　Wang Xiushun also to reporters calculate, according to Wang Yuan Company's preliminary planning, the company plans to draw 365 million tons of seawater each year, can achieve 4.7 billion annual economic benefits, of which, the average cost per ton of seawater desalination around 4, the cost of wind water transfer is about 2 pieces. "We can make 1.2 billion a year to get rid of costs," he said.　　"Wang Xiushun said.　　According to Wang Xiushun, Wang Yuan company has now and Shenhua, Datang and other enterprises to reach an agreement, desalination processing after the transaction price of 10 yuan per ton. "The theoretical conclusions that scientists can draw are not practical, and I think the project will be done in 30-50 years."　　Zhang Bo told reporters.　　And according to the calculation of Wang Yuan, the planned project in full implementation of the case, static investment recovery period (including the 3-year construction period) for 6 years before the tax, after 7 years, internal rate of return of about 20%. "This project we have been prepared for 6 years, China Water Conservancy and Hydropower Science research Institute and other domestic 51 research institutes have participated in the assessment and research, this is not Arabian Nights."　　"Wang Xiushun said. The dispute of the practicability of seawater "agriculture water saving and groundwater even take snow is unfavorable to our area long-term development." At the same time, it will destroy the ecological balance. "Land and sea co-ordination, water West" Project is a major strategic choice of our country, but also conducive to the development of regional advantage resources.　　"The Development Research center of Xinjiang Autonomous Region People's government Li New said in an interview. However, along with the "South-to-north Water Diversion" project to alleviate the severe shortage of water in North China, as well as the Three Gorges Large-scale water conservancy project to solve the flood problem in the lower reaches of the Yangtze River, the "Sea West" also has the core problem of destroying the ecological balance, such as man-made natural disasters caused The diversion canal along the Inner Mongolia border may cause saline-alkali dry depressions to form and so on.　　At the same time, some experts questioned the usefulness of seawater.　　At present, some coastal cities due to seawater intrusion caused by land ph change, if the water leakage along the way, lack of rainfall in Inner Mongolia, Xinjiang is likely to lead to land salinization.　　Zhang Baoyin, secretary general of the Ocean branch of China High-tech Industrialization Research Institute, said that the introduction of seawater would not affect the inland soil structure, which would never have any consequences. "The seawater in the Gulf is connected with the Pacific Ocean, the general self-purification cycle is 5 years, and the introduction of Bohai sea water can shorten the purifying cycle, promote the environment change in Bohai Bay Area, and even promote the development of aquaculture."　　"Zhang Baoyin said. "We have solved the problem of environmental protection, the FRP pipe conveying seawater has advanced technology of anticorrosion and leak-proof, and pipeline construction is also the responsibility of China Railway Building Group, so we have protection both technically and in construction."　　Wang Xiushun told reporters. It is understood that at present, Inner MongoliaThe National Development and Reform Commission and the Liaoning Provincial development and Reform Commission have already targeted the project, and according to Wang Xiushun, 5 sites involved in the project have been started. At the same time, Wang Xiushun also stressed that the introduction of seawater into the desert, Xinjiang can add at least 1.8 billion mu of agricultural land. "Israel has a high utilization of deserts and the size of Xinjiang is only 4%." "Wang Xiushun said.
