Chapter 349 Water and Salt

Egypt.

4.6 kilometers southeast of Kom Ombo City.

After more than ten days of construction, the new Gobi Desert area has changed drastically.

At the same time, Juxi No. 1 also completed the excavation of the canal's double track, returned to Hongku Port again, and is currently resting in Hongku Port.

With the opening of the double line of the canal between Hongku Port and Kom Ombo City, the previous boat schedule every 8 hours can now be increased to every 2 hours.

Of course, this also needs to increase the unloading speed of the temporary dock, otherwise the speed can be further improved.

But at this time in the Gobi Desert new area.

The person in charge, Hu Mingliang, didn't pay too much attention to the wharf area. After all, there were no giant rhinoceros-shaped canal-drilling boats. With the help of excavators, they couldn't dig much earth at all. Therefore, he focused on the construction of supporting facilities in the Gobi Desert New Area.

For example, the water purification plant that has just been built with modular equipment.

On the side of the Gobi Desert, there is also a relatively high mountain depression, the height of several hills is between 173 and 192 meters, and there is a small basin in the middle, with an area of ​​about 4.9 square kilometers.

After the investigation by the leader of the planning team, Kamijo Beiyang, he thought that this mountain depression could be used to build a water storage reservoir.

As for the water source of the reservoir, it comes from the sea water of the canal.

At this time the water purification plant has been put into use.

The roof of the water purification plant is covered with a large area of ​​solar panels, and these solar panels are also arranged in a concentric circle, reflecting part of the sunlight to the molten salt thermal storage column in the middle.

This tropical desert area is the most suitable for arranging solar panels.

In the tropical desert area of ​​Egypt, the air is dry and cloudless, and the daily sunshine time is about 8-11 hours, and the light intensity per square meter can reach 2000-3000 kWh.

The solar power generation system of the water purification plant is a photovoltaic photothermal composite power generation system, which can solve the disadvantage that photovoltaic solar energy can only generate electricity during the day.

At present, the solar power generation system of the water purification plant has a power generation area of ​​40 square meters and can generate 240 megawatt hours of electricity every day.

The water purification system of the water purification plant adopts Homo sapiens' unique water purification technology - biological nanostructure infiltration technology.

The characteristic of this technology is that the cost of the permeable layer is very cheap, and the service life can reach about 17 months.

Moreover, this technology has another feature, that is, it can accelerate water molecules to pass through the permeable layer through pressurization, so as to achieve the effect of increasing production and saving equipment footprint.

At present, the water purification system of the water purification plant can produce 5000 cubic meters of pure water per hour and 12 cubic meters per day.

Hu Mingliang stood outside the pressurized water chamber.

Huang Chongxin, director of the water purification plant, pointed to both sides of the pressurized water room: "Manager, this is the temporary storage pool for purified water, and this is the storage pool for miscellaneous salt."

"How much miscellaneous salt is produced every day?"

"About 4200 to 4400 tons per day, the salinity of seawater on the Red Sea side is relatively high."

Hu Mingliang squeezed his beard: "We must find a way to deal with these miscellaneous salts."

"There are supporting facilities on it, but the equipment is still at Hongku Port, and it will take about five days to transport it to Kom Ombo." Huang Chongxin replied.

Hu Mingliang's assistant took out a tablet computer and found out the equipment transportation situation of the supporting factory: "It is indeed at Hongku Port, do you want to urge it?"

"No, all the tasks in the transportation department have been lined up. It's not good to jump in the queue temporarily. Don't mention this kind of thing in the future." Hu Mingliang directly vetoed it.

"Sorry, I understand." The rookie assistant hurriedly apologized.

Hu Mingliang turned his head: "Old Huang, you are also in charge of the supporting factories, and how many temporary workers can your factory take?"

"Temporary workers? Hmm..." Huang Chongxin thought for a while: "About 20 to 30 people, mainly for solar panel dust removal and miscellaneous salt processing plants."

"Okay, let's just have 25 people!"

"Yes, I will arrange the team leader as soon as possible."

The two chatted for a while, and suddenly Huang Chongxin remembered something: "Manager, the things produced by the miscellaneous salt processing plant need you to do a good job in supporting them."

"Salt Brick, I will arrange a team to take care of it."

For the 4200-4400 tons of miscellaneous salt produced every day, it is naturally impossible to process edible salt or industrial salt, because so much cannot be eaten.

According to this scale, the entire water purification plant will produce millions of tons of miscellaneous salt a year, and this is just one of the water purification plants.

In Homo sapiens' plan, 80 new cities will be built in Egypt. These cities will definitely need water purification plants, and hundreds of millions of tons of miscellaneous salt will be produced every year by then.

Obviously, edible salt and industrial salt cannot digest this production capacity.

But if it is not treated, it will take up space and even pollute the surrounding land.

Therefore, after Homo sapiens developed water purification technology, they were thinking about how to use these miscellaneous salts from waste. After much deliberation, they finally thought of the construction field.

By adding aluminum alloy mesh, as well as coagulant and structural reinforcement, the miscellaneous salt is pressed into bricks.

If it is in other places, it is difficult to apply this compressed salt brick to the construction field.

But where is it?

This is a tropical desert area, with high temperature and little rain all year round, and dry air. The salt bricks will not absorb water and dissolve, let alone be washed away by rain.

Of course, considering the structural strength of salt bricks, Homo sapiens did not include them in high-rise buildings, and even urban buildings did not approve the use of salt bricks.

Now the use of these salt bricks is to build simple roads, especially simple roads passing through desert areas, and salt bricks can be used to lay foundations and road surfaces.

Anyway, there is no problem of soil pollution in these desert areas, as long as salt bricks are not used in the valley plains and delta plains of the Nile River.

In addition, roads in seawater rice planting areas can also be paved with salt bricks. After all, seawater rice planting areas must be saline-alkali land, so there is no need to care too much about soil salinization.

These miscellaneous salts can be used as waste to build roads in the Sahara desert area.

the other side.

In the staff dormitory area of ​​the Gobi Desert New Area.

After work, all the employees hurried back to their rooms.

These days are really uncomfortable. Although the new human beings are relatively adaptable, many people are actually not used to it when they have gone from tropical rainforests and tropical monsoons in Southeast Asia to tropical deserts in Egypt.

Like taking a shower.

In Southeast Asia, one bath a day is standard, and two or three baths a day are also quite common.

But in Egypt, where water resources are scarce, taking a bath once a day is a luxury.

However, Homo sapiens still cares a lot about the life of its employees.

As soon as the water purification plant was put into use, shower rooms and swimming pools were opened in the dormitory area.

A dozen local temporary workers who had just joined Homo sapiens were brought to the swimming room by their captain.

"Don't stand still, change your clothes quickly."

The temporary workers who woke up from a dream hurriedly went to the locker room to change their clothes, and then followed the captain to find a small swimming pool.

The cold pure water made everyone refreshed and swept away their previous fatigue.

A young local temporary worker asked curiously: "Captain! How much does this swimming pool cost once?"

"No money, this is one of the employee benefits, the infrastructure here is not good, I wash every day in Johor."

"No money?" Many temporary workers were shocked.

After all, in their previous lives, this kind of indoor swimming pool was usually enjoyed by rich people, and ordinary people could only swim in the Nile River at best.

"Don't make a fuss, it's just a small benefit."

A group of temporary workers became more and more envious of the life of Homo sapiens company.
