October 15th.

The southeast coast of Qilu Province, near the port of Rizhao.

Workers at the power grid are busy laying an ultra-high voltage line, and in the mountains to the west of the construction site, a medium-sized thermal nuclear power plant has just been established.

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

On the east coast of the construction site, there is a huge integrated plant, which is specially equipped with a medium-sized nuclear power plant, which shows the size of this plant.

Inside the laboratory of the factory.

Yang Bai, the chief technical researcher of the rock-forming laboratory of the Materials Research Institute of Thinking 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 50,000 cubic meters of seawater pumped from the Yellow Sea.

Yang Bai took the tablet and instructed the assistant on the side: "Adong, insert the sodium chloride adsorption box." ”

"Roger." Lin Dong, whose skin was tanned, picked up the remote control and manipulated a box above the pool, which was connected to a mechanical arm.

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

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

Immediately, Lin Dong pressed the switch, and bursts of electricity flowed into the box, and the seawater in the seawater pool began to react subtly.

The sodium chloride in the seawater is attracted by the catalytic matter and current of the box, and the sodium chloride quickly adheres to the hollow pipe.

Just like a piece of snowflakes falling on a hollow pipe, the sodium chloride crystals are rapidly generated, and in less than three minutes, the sodium chloride components in the seawater are absorbed by the box.

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

At this time, Lin Dong pressed the pause button, there was a bucket cabin in the workshop, and another mechanical arm inserted a row of solid pipes directly into the hollow pipes of 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.

Yang Bai stood next to the seawater pool, took out the salinity meter from the tool cart on one side, and reached out to probe the salinity meter into the seawater.

Salinity: 0.37 mg/l

He shook the salinity meter and recorded the values on the plate.

In addition to water, salt compounds account for 99% of seawater, which means that seawater desalination is mainly to remove salt compounds.

The six salts in the main seawater are: sodium chloride 27.213 g/L, magnesium chloride 3.807 g/L, calcium carbonate 0.123 g/L, magnesium sulfate 1.658 g/L, calcium sulfate 1.260 g/L, magnesium bromide 0.07 g/L.

"Xiaoou, you can test the catalyst loss rate of the sodium chloride adsorption box." Yang Bai commanded.

"Okay." Ou Simin 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.

These inorganic salts continue to be adsorbed into the seawater pool.

After more than half an hour, the water in the pool has become clearer, and 99% of the salts of the solvent have been absorbed, leaving only a very small percentage. 78 Chinese first release www.7* m.7*

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

Among them, the catalyst of magnesium bromide adsorption box is not only the highest cost, the loss rate has been high, with an average adsorption of 12 pools of seawater, and the magnesium bromide crystallization catalyst will lose more than 86%.

Compared with the sodium chloride crystallization catalyst, which can be replaced at one time, adsorbs 1,300 pools of seawater, and is cheap, the two are simply very different.

He took his tablet and walked towards the two seawater pools next door, where there is a metal adsorption area and an organic matter removal area.

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

Yu Hanchao, who was wearing protective clothing, took off his mask and replied as he walked: "It's okay, 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 flat plate, but there were not too many surprises: "The efficiency of the uranium adsorption box can be slowly improved, and we are not in a hurry." ”

"Didn't you say that our desalination plant will be put into use at the end of this year?" asked Yu Hanchao in surprise.

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

"Uh...... That's just as well. Only then did Yu Hanchao react.

These trace elements are abundant in liquid water, and the tap water we use generally does not have a thankless effort to remove these trace elements.

Unless it is some excessive trace elements that are harmful to the human body, such as mercury and lead, which are two elements of special concern.

Otherwise, the waterworks will be idle and sore to remove the trace elements of gold, silver, copper and iron, unless there is a serious exceedance, but the trace elements in the seawater generally do not exceed the standard.

The trace elements that do not exceed the standard are conducive to human drinking, and they become pure water when they are removed, 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 glittering metal, and the bottom of the other bucket cabin was shining silver.

Yu Hanchao lifted the bucket cabin, opened the bulkhead on one side, and used a broom to gently sweep the gold sand at the bottom into the small bucket.

"All the gold that's been adsorbed these days is here"

"No, this is the second batch."

Yang Bai grabbed a handful of heavy gold sand, judging from the fineness on it, the purity was already equivalent to 999 gold.

"How many are in the first batch"

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

"Silver?"

"There are 17.51 kilograms of silver."

Yang Bai nodded, still very satisfied with this adsorption efficiency.

The extraction of gold and other metal minerals from seawater is one of the future directions of the international mineral field.

Minerals on land have either been opened or discovered; The moon and asteroids in outer space are not only not suitable for development technology, but also for cost.

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

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

In addition, potassium, iodine, phosphorus, gold, silver, copper, iron, aluminum and other elements can be extracted, which are strategic materials to a certain extent.

Yang Bai is carrying out some of the catalyst research work.

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

On the other side, a water pipeline also starts from Rizhao and extends inland along the railway line to the city of Xi'an.

In the future, the pipeline will be able to bring desalinated water to inland areas, especially the Guanzhong Plain and the Loess Plateau, which are severely short of water.

It is beneficial to alleviate local water use, especially the ongoing greenhouse agriculture and coal chemical industry, which require large water resources.

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

In fact, with the popularization of nuclear fusion power plants, the cost of social production is gradually decreasing, and seawater desalination has become a profitable new industry with the support of new technologies and cheap electricity.
