The average energy consumption per gram of gold smelting is only 1~12 kWh.
Compared with going to a gold mine, it is also a mine and engineering equipment. Miners risk their lives to add a lot of chemical reagents. If they encounter a low mining area, they may lose money.
Bohai sea is near land, and the richness of marine elements is higher than that of deep sea, and the average gold content per ton of seawater is about 5~ mg.
The ocean with the highest gold content in seawater is the Caribbean near Central America, with an average gold content of 15~1 mg per ton of seawater.
Dongying seawater desalination plant can get 5~ kg of gold for every 100 million cubic meters of seawater.
Gold alone can earn 120,000 to 20,000 yuan a year.
After continuous refining, seawater enters the water purification area, directly passes through the water purification film, then purified water enters the water purification preparation area, and filtered crude salt enters the crude salt preparation area.
At present, the factory can handle about 350,000 cubic meters of seawater a day, and the limit state can handle 50,000 cubic meters of seawater a day.
A temporary small platform was set up in the gate control room of the factory water pipeline to raise the festive red banner.
Several local leaders cut the ribbon with the manager of Blue Times Dongying Branch and the director of the desalination plant to celebrate the commissioning of the desalination plant.
"I declare the first phase project of Dongying seawater desalination plant officially put into production."
In addition to the desalination plant employees, there are also many local media and national news reporters in Shandong Province.
There was a clap at the scene and the photographers snapped the camera.
Wang Xiaobing came to Dongying after an interview with Chagan Lake. After the ribbon-cutting ceremony, she interviewed Wang Competitive, the manager of Dongying Branch.
"Hello, Manager Wang. How much pure water can this desalination plant supply to Dongying every year?"
Wang Competitive replied with a smile, "At present, we should supply 340,000 cubic meters of pure water every day and expect 100 million cubic meters of pure water every year."
Wang Xiaobing turned to stare at the camera and said, "According to the phase data, Dongying City had a water volume of 920,000 cubic meters last year, and in 1999, the annual water consumption reached a peak of 25.9 billion cubic meters. The seawater desalination plant will be put into operation or will completely improve the water problem in Dongying area, which will also enhance the vitality of industry and agriculture."
As soon as the camera turned, she asked again
"Manager Wang, will your company expand the scale of seawater desalination plant in the future?"
Wang Competitive took the interviewer to the factory sand table, which is the terrain of Shandong Province.
"In the future, our company will expand the scale of Dongying, Daocheng and Rizhao desalination plants and gradually build water pipelines."
Sand table is divided into two water conveyance lines from Dongying Old Yellow River Estuary, namely
Dongying Old Yellow River Estuary on Dongying South Line-Dongying City-Binzhou Boxing-Zibo Huantai-Zibo City-Zichuan District-Boshan District
Dongying Old Yellow River Estuary of Dongying North Line-Guhua District of Binzhou-Binzhou City-Quancheng Shanghe-Linyi of Dezhou-Yucheng of Dezhou-Gaotang of Liaocheng-Liaocheng City-Taiqian (Henan Province)-Heze Yuncheng-Heze City
The island city desalination plant should be self-sufficient and Weifang Gaomi, and Weihai and Yantai are preparing to jointly build a desalination plant.
Weifang also built a seawater desalination plant, which was incorporated into Dongying South Line to reduce the water pressure of Dongying seawater desalination plant.
On the Rizhao factory side, the Rizhao line will be established along the way through Rizhao Lanshan District-Linyi Junan-Linyi City-Linyi Lanling-Zaozhuang City.
There are also a large number of feeder lines and reserve reservoirs.
Many reporters were also shocked to see this grand plan.
"… our company plans to increase the desalinated water in Shandong Province to 100 million cubic meters per year in the next five years"
"Will such a huge investment bring pressure to your company’s finances?" Shandong TV reporter asked with a little concern.
Wang Competitive replied with a smile, "The pressure is that we and Shandong Provincial Water Corporation have planned to invest 9% of the profits in the construction of the pipe network in the next five years."
In fact, Shandong Province attaches great importance to the water pipeline plan of Suiren Company, and has set up a special team to cooperate with land acquisition and route planning along the way, and has also given a lot of subsidies.
Because these water pipelines and desalination plants are a great opportunity for Shandong Province.
Although Shandong Province is a strong industrial and agricultural province in the north, the annual precipitation is 6~ mm.
The problem is that industry and agriculture consume a lot of water, and a few industrial and agricultural pollution problems lead to very poor water quality in Shandong Province.
In addition, the huge population leads to a much lower per capita water consumption than some areas in the northwest (the population is small but the per capita water consumption is high).
As Shandong TV station and national news reported one after another, the glistening desalinated water flowed out of the factory continuously.
