October 15th.

The southeast coast of Qilu Province, near Rizhao Port.

The power grid staff are busy laying an ultra-high voltage line, and in the mountainous area on the west side of the construction site is a medium-sized fire nuclear power plant that has just been established.

Anyway, all nuclear fusion power stations use the thermal power station name outside.

On the east coast of the construction site, there is a huge comprehensive factory, which specifically equips this factory with a medium-sized nuclear power plant, which shows the size of this factory.

Inside the laboratory of the factory.

Yang Bai, chief technical researcher of the Rockmaking Laboratory of the Institute of Materials Research of Siwei Society, is experimenting with a group of researchers.

A pool with a length of 50 meters and a depth of 20 meters was filled with sea water pumped from the Yellow Sea, with a total of 50,000 cubic meters.

Yang Bai held the tablet and ordered the assistant beside him: "A Dong, insert the sodium chloride adsorption box."

"Received." Lin Dong, whose skin was bronzed, picked up the remote control and controlled a box above the pool, which was connected to a robotic arm.

The box is made of hollow pipes, which are like an enlarged version of a car condenser, with a length and width of about 3 meters and a height of 5 meters.

The robotic arm slowly inserts the box into the seawater pool.

Then Lin Dong pressed the switch, and bursts of current flowed into the box, and the sea water in the sea pool began to react subtly.

The sodium chloride in the seawater is attracted by the catalytics and currents in the box, and the sodium chloride quickly attaches to the hollow pipe.

Just like snowflakes falling on hollow pipes, sodium chloride crystals were quickly generated. In less than three minutes, the sodium chloride component in the seawater was absorbed by the box.

Lin Dong pressed another switch, and then the box left the sea pool and moved horizontally to one side in mid-air until the box and the robotic arm moved to a workshop on one side together.

At this time, Lin Dong pressed the pause button. There was a bucket compartment in the workshop, and another robotic arm inserted a row of solid pipes directly into the hollow pipe in the box.

The crystalline salt attached to the hollow pipe is directly squeezed out by the solid pipe and falls into the bucket compartment below.

At the sea pool, Yang Bai stood next to the sea pool, took out the salinity meter from the tool cart on one side, reached out to penetrate the salinity meter into the sea water.

Salinity: 0.37 mg liter

He shook the salinity meter and recorded the value on the tablet.

In addition to water, salt compounds account for 99 in seawater, which means that seawater desalination mainly involves removing salt compounds.

The six types of salts in the main seawater are: 27.213 grams of sodium chloride, 3.807 grams of magnesium chloride, 0.123 grams of calcium carbonate, 1.658 grams of magnesium sulfate, 1.260 grams of calcium sulfate, and 0.07 grams of magnesium bromide.

"Xiao Ou, you can test the catalyst loss rate in the sodium chloride adsorption box." Yang Bai ordered.

"Okay." Osmin carried the sampler to the sodium chloride adsorption box.

Lin Dong continued to operate the magnesium chloride adsorption box, calcium carbonate adsorption box, magnesium sulfate adsorption box, calcium sulfate adsorption box, and magnesium bromide adsorption box.

Continue to absorb these inorganic salts into the seawater pool.

After more than half an hour, the water in the seawater pool had become clearer, and the salts that accounted for 99 of the solvent were absorbed, leaving only a very small proportion.

However, Yang Bai was not too happy because the catalyst loss rate of the magnesium sulfate adsorption box, calcium sulfate adsorption box and magnesium bromide adsorption box did not meet expectations.

Among them, the catalyst in the magnesium bromide adsorption box not only has the highest cost, but the loss rate has always remained high. On average, 12 pools of seawater will be adsorbed, and the loss of magnesium bromide crystal catalyst will exceed 86.

Compared to being able to replace it at one time, adsorb 1,300 pools of seawater and creating cheap sodium chloride crystallization catalysts, the two are simply a very different difference.

He held his tablet and walked towards the two seawater pools next door, where the metal adsorption area and the organic matter removal area.

"A Chao! What are you going to do?"

Yu Hanchao, wearing a protective suit, took off his mask while walking and replied: "It's OK, the adsorption efficiency of gold and silver is quite high, but the adsorption efficiency of uranium is not good."

Yang Bai looked at Yu Hanchao's data through the tablet, but there were not many surprises: "The efficiency of the uranium adsorption box can be gradually improved, and we are not in a hurry."

"Didn't it mean that our desalination water plant will be put into use by the end of this year?" Yu Hanchao asked in surprise.

Yang Bai rolled his eyes: "You guy is confused when you do experiments, these trace elements do not affect the production of desalinated water."

"Uh...that's true." Yu Hanchao reacted.

These trace elements are found in large quantities in liquid water bodies. The tap water we use generally does not have to be thankless to remove these trace elements.

Unless it is some trace elements that are harmful to the human body, such as mercury and lead, which are particularly concerned about.

Otherwise, the tap water plant will be idle and get rid of trace elements such as gold, silver, copper and iron. Unless there is a serious phenomenon of exceeding the standard, the trace elements in the sea water will generally not exceed the standard.

Trace elements that do not exceed the standard are beneficial to the human body's drinking. If they are removed, they will become pure water, but they cannot be drunk for a long time.

Yang Bai and Yu Hanchao walked into the workshop next door together. In one bucket cabin, the bottom was covered with golden metal, while the bottom of the other bucket cabin was sparkling silver.

Yu Hanchao raised the bucket compartment, opened the bulkhead on one side, and gently swept the gold sand at the bottom into the small bucket with a broom.

"The gold that has been absorbed these days is here"

"No, this is the second batch."

Yang Bai grabbed a handful of heavy gold sand. Judging from the quality above, the purity is equivalent to 999 gold.

“How many are there in the first batch”

Yu Hanchao thought for a while and replied: "2.44 kg."

"Where is silver"

“There are 17.51 ​​kilograms of silver.”

Yang Bai nodded, and was very satisfied with the adsorption efficiency.

Refining gold and other metal minerals from seawater is one of the future major directions in the international mineral field.

Land minerals have either been opened or have been discovered; while the moon and asteroids in outer space are not only not satisfied with the development technology, but also the cost is not suitable.

The seabed and seawater of the ocean have become the new goals of mankind.

Rizhao seawater desalination factory can currently extract sodium chloride, magnesium chloride, calcium carbonate, magnesium sulfate, calcium sulfate, and magnesium bromide from seawater on a large scale.

In addition, these elements such as potassium, iodine, phosphorus, gold, silver, copper, iron, and aluminum can also be extracted. These things are strategic materials to a certain extent.

Yang Bai is working on some catalyst research.

However, their research and development work does not affect the engineering construction of the seawater desalination plant.

On the other hand, a water supply pipeline also starts from Rizhao and extends inland along the railway line, and will eventually reach the Xi'an City.

In the future, the water supply pipeline can input desalinated water into inland areas, especially the Guanzhong Plain and Loess Plateau with severe water shortage.

It is conducive to alleviating local water use, especially ongoing greenhouse agriculture and coal chemical industry, which require huge water resources to support.

In addition, the excess desalination water can also be supplied to residents as domestic water.

In fact, with the popularity of nuclear fusion power plants, social production costs are gradually declining. Seawater desalination has become a profitable emerging industry with the support of new technologies and cheap electricity.
