After leaving the presidential palace, Liao Bin visited several other powerful people in Angola in succession. It was nothing more than sending flying cars and sending money to open the road. In addition, the land required by Qingquan Technology was indeed the most deserted Namib Desert. In the name of the experiment, and promised to help Angola in desert greening for free after the future results.
Within a few days, Liao Bin received the consent of the Angolan government. The two sides officially signed a cooperation. Qingquan Technology exchanged 10 billion US dollars of new seeds for 30 years of use rights of 1,000 square kilometers of land along the Atlantic coast of Namib for scientific experiments. ， Research on the technology of managing arid deserts!
As far as the Angolan government is concerned, this pie fell off during the day! A broken desert, nothing could be exchanged for a new seed of 10 billion U.S. dollars, a few powerful people in charge, and everyone's pockets swelled instantly, not to mention these are new energy trees that can provide a long-term source of income !!
In addition, Qingquan Technology has very eloquently sent to every Angolan official in charge an atmospheric and beautiful "Sheng Tang Datang" flying car, plus a fund for activities unknown to the outside world!
For Qingquan Technology, the real cost is actually not much. The seed of 10 billion US dollars is just seeds, not cash. As for the cost of seeds, this has been reduced to a very low level! The real need to spend cash is to open the way for those in power!
I did n’t spend a lot of money to get a piece of land. Although the agreement wrote about 30 years of use rights for research on desert management, it was really not that easy when Qingquan Technology was in the hands. As the most important back-off base!
1,000 Hercules cargo transport flying cars are fully loaded with goods, which can transport millions of tons of materials at one time; 10,000 flying cars with 100 surnames will transport all construction workers in charge at one time.
This time Qingquan Technology set up its own construction company, recruiting construction workers, technical talents, etc. Now the overall environment is still not good, and there is a surplus of talents in the construction industry. Qingquan Technology found all kinds of talents with just one move.
Mo Qingming stopped his "Shengshi Datang" flying car, and when he came to the speeding car, a hot wave hit, and the golden desert was like waves, forming countless beautiful crescents.
It's extremely desolate here. There are some desert plants, cacti and the like only near the sea. Other creatures can't be seen at all. There may be some desert snakes and scorpions, but most of them are hiding in that hole. inside.
Hai Dao is very clean, azure blue, corresponding to the blue sky and cloudless sky. The Buddha is like a reflection, which makes one's mind open. There is a book business spirit, which is used to exhort Fang Yan and point the country's pride!
"How? This land is good!" Liao Bin saw Mo Qingming in a daze, came over and patted his shoulder with a smile.
"I'm sorry to say that more than 10 billion U.S. dollars have changed this barren land, and the company doesn't know how much to invest here to build a similar base! The deserted barren land has spent so much. More! "Mo Qingming shook his head.
He is really not very satisfied with it. It's all desert and nothing. It's too desolate!
"What I want is a barren and barren land. How did the boss explain to me at the beginning? Now the world has been divided up, and there is only such a place that can open up our company. Otherwise, how can we hide it! Liao Bin also shook his head. There is no way. If the company wants to develop, it is natural to get rid of various restrictions from the country.
But all the land of the earth already has a master, even the Antarctic has a master, uh, they are penguins! No matter which country the company goes to, it will be subject to various restrictions. It can only find a backward country, find a barren land, and slowly develop!
"Yeah! But having said that, building a huge base in such a desolate place is also a huge achievement!" Mo Qingming smiled very sullenly. For everyone in Qingquan Technology, everyone is young What are you afraid of, man!
"Come step by step. The first thing this base needs to solve in the future is water. There is nothing when there is no water. We are useless at Tianda!"
That's right, this base was named Future, Future Base by Qingquan Technology!
"Don't you see the company drain me? Rest assured, our materials company has already developed a variety of new seawater desalination materials, plus other new seawater desalination technologies, here will be flooded in the future!" Mo Qingming smiled proudly.
Liao Bin is not engaged in technology. He is in charge of sales. He is completely curious about the technology!
"Hurry up and listen!"
With the introduction of Mo Qingming slowly, the comprehensive display of seawater desalination technology was presented in front of Liao Bin.
Desalination is the use of seawater desalination to produce fresh water. It is an open source incremental technology that realizes the utilization of water resources. It can increase the total amount of fresh water without being affected by time, space and climate. It can ensure stable water supply for coastal residents' drinking water and industrial boiler make-up water.
The process of obtaining fresh water from seawater is called seawater desalination. The seawater desalination methods currently used include seawater freezing method, electrodialysis method, distillation method, reverse osmosis method, and ammonium carbonate ion exchange method that can be profitable. Currently, reverse osmosis membrane is used. The reverse osmosis method quickly occupied the market with its advantages of simple equipment, easy maintenance and modularization of equipment, and gradually replaced the distillation method as the most widely used method.
There are more than 100 scientific research institutions in more than ten countries in the world conducting desalination research, and there are hundreds of desalination facilities with different structures and capacities. A modern large-scale desalination plant can produce thousands, tens of thousands or even millions of tons of fresh water every day.
The cost of water is constantly decreasing. Some countries have reduced the price to the price of tap water. In some areas, the amount of desalinated water has reached the national and urban water supply scale.
Currently, the mainstream seawater desalination technologies in the world are mainly two types: traditional distillation (thermal) and reverse osmosis (membrane). Among them, low-efficiency distillation, multi-stage flash evaporation, and reverse osmosis are the mainstream in the world. Technology, distillation method is currently the most widely used, with the advantages of low seawater pretreatment requirements and high quality of desalinated water. The disadvantages are serious energy consumption and difficult to treat dirt!
The reverse osmosis membrane method has the advantages of low investment and low energy consumption, but the seawater pretreatment requirements are high, that is, when the reverse osmosis method is used to desalinate the seawater, some seawater treatment must be performed in advance.
Of course, in addition to these two seawater desalination technologies, there is also a frozen seawater desalination treatment technology. This technology uses the three-phase point of seawater, even if seawater vapor, liquid, and solid three-phase coexist and reach a special point of equilibrium. If the pressure or temperature deviates from the three-phase point, the balance is broken, and the three phases will automatically approach one or two phases.
Vacuum freezing seawater desalination is a low-cost desalination method that uses the three-phase point principle of seawater and uses water itself as a refrigerant to simultaneously evaporate and freeze seawater, and then separate and wash ice crystals to obtain desalinated water.
Compared with the distillation method and membrane desalination method, the frozen seawater desalination method has low energy consumption, light corrosion and scaling, simple pretreatment, small equipment investment, and can handle seawater with high salt content, which is an ideal seawater desalination method. law.
However, both the freezing method and the distillation method have disadvantages that are difficult to overcome. The distillation method consumes a large amount of energy and generates a large amount of scale in the instrument, but the fresh water is not much. The freezing method also consumes a lot of energy. However, the fresh water obtained had a bad taste and was difficult to use.
After listening to Mo Qingming's speech, Liao Bin finally understood some of the knowledge of seawater desalination. After thinking about it, he said, "How come, you have invented a special material and prepared to Desalination of seawater by membrane method? "
Mo Qingming smiled and said, "Clever! I am studying materials, and naturally start from materials, but you are not entirely correct, this time I brought over the latest research seawater desalination film material!"
"I don't understand your technology. How can this film desalinate seawater?" When it comes to technology, Liao Bin is completely confused.
"Membrane separation technology refers to the technology of selective separation of a mixture of molecules with different particle sizes at the molecular level when passing through a semi-permeable membrane. In simple terms, water molecules and sodium molecules in seawater are separated because water molecules It is smaller than sodium molecules, so when designing this film, it is only necessary to open the pores only through water molecules! "Mo Qingming explained patiently!
"How simple?" Liao Bin's eyes widened and it was hard to imagine that this seawater could be turned into fresh water by passing a simple film. How could the whole world suffer from water shortage!
"The principle is how simple it is, but this biomimetic material is very similar to biological cell membranes. Before we developed a new technology, its cost was still very high, and the yield was very low. The price is too expensive, and only the second-stage reverse osmosis method can be used to desalinate the seawater. Now, simply pressurize the seawater through the new material film to obtain fresh water! "Mo Qingming smiled proudly stand up.
Inside the company, especially the research institute, the competition between them is still very fierce. Everyone does not care about the material things, but pays great attention to the internal honor. After receiving this material company from Mo Qingming, compared with other The research department is inferior, but he Mo Qingming has always been a director, and he needs to come up with achievements that can convince other people.
This time, the biomimetic filter membrane that Mo Qingming took the lead in researching can quickly, simply and cost-effectively desalinate seawater, which can be said to be a promising technology!
There are too many countries and regions in the world without water! Not to mention other countries and regions, the Beijing-Tianjin-Tangshan region in the north, the North China region, and the inland region in the northwest are all very scarce, which seriously hinders the development of all aspects of society. New materials, there will be endless water, use as you want! (To be continued.) Mobile users please browse and read for a better reading experience.
