August 11th.

The desalination plant of the first phase of the Bohai Sea Area Desalination Project has been officially completed.

President Zhu Jianguo and Vice President Ma Chang of Dongtang Yinhe Water Company, as well as Yuan Quan, director of the Desalination Research Institute who came here to guide the work, as well as Fang Ping and Zhang Haifeng of Haifeng Wind Power, gathered together at the first phase of the desalination plant. in.

"Yuan Suo, can it be put into trial operation now?" Zhu Jianguo asked.

Yuan Quan nodded: "Okay."

"Let's start!" Zhu Jianguo ordered to the factory director on the side.

The factory director quickly ordered the workers to start up the equipment of the desalination plant according to the operating procedures.

The cross-section of the desalination reservoir of the desalination plant is a trapezoid, with a design length of one kilometer and a width of fifty meters.

Seawater desalination membranes are installed on the slopes on both sides. The length of the slope is kilometers and the width is 20 meters. The area on one side is 20,000 square meters and on both sides is 40,000 square meters.

The entire desalination reservoir is semi-sealed, and seawater can pass through the head and tail.

There is a pressure gate every 100 meters. After seawater enters the first gate, the pressure gate is closed and pressed to the other side.

When one kilometer is pressed from beginning to end, 95% of the water is pressed to the other side of the desalination membrane like a juicer.

At the end of the process, only 5% high-concentration sodium chloride and other solutions remain. These solutions are discharged into a special brine reservoir, and then transported through pipelines to the sea salt chemical plant and storage not far away.

The fresh water that is also squeezed out is quickly transported through pipelines to where it is needed in the reservoir.

Only one of the desalination canals is currently in operation. This desalination canal alone can produce 28 billion cubic meters of fresh water a year.

This seawater desalination plant has planned a total of three desalination canals, two of which are used for daily production and one is for backup.

If the three desalination canals are operated at full capacity, they can produce 84 billion cubic meters of fresh water a year.

Of course, full capacity is impossible. It’s not that the desalination plants can’t produce it, but that the transportation pipelines can’t transport so much fresh water.

The water transmission pipeline currently being built has an annual water transmission capacity of 15 billion cubic meters per line.

If the desalination plant were to operate at full capacity, six water pipelines with an annual capacity of 15 billion cubic meters of water would be needed.

Therefore, the seawater desalination plant is currently putting a desalination channel into trial production, and the operating efficiency is only about 40%.

In front of us is a reservoir with an area of ​​100,000 square meters, a depth of 30 meters, and a capacity of 3 million cubic meters of water. The water level is rising at a speed visible to the naked eye.

Don't think that a 3 million cubic meter reservoir can meet the fresh water production rate of a desalination canal. The fresh water produced by a desalination canal in one hour can fill the reservoir.

Therefore, during the trial operation, only 40% of the power is activated, but even so, the reservoir will be completely filled in about two and a half hours.

Vice President Ma Chang quickly took a bucket tied with a rope and threw it into the fresh water reservoir. After a while, he picked up a bucket of water.

"Come on, how about you try this water?" Ma Chang directly filled a glass of water with a disposable cup and tasted the taste of the water.

Others also picked up cups to fill with water and drank.

"not bad!"

"There is no bitterness."

"It's almost like pure water."

"Great, now the water problem in the north can be solved." Ma Chang drank a glass of water happily.

"It's not that simple! The amount of water delivered by the water pipeline is a problem." Zhu Jianguo smiled bitterly.

Everyone couldn't help laughing when they heard it. Now it's not a matter of pipes waiting for water, but water waiting for pipes.

"Don't worry, Mr. Zhu. I will report this issue to the superiors immediately. Since there is so much fresh water surplus, we cannot let this production capacity be wasted here." Ma Chang said quickly.

"Then I'll trouble you, Mr. Ma."

"It's no trouble, it's all part of your duties."

Ma Chang wishes there would be more of this kind of thing. After all, the more important the water company is, the higher his position will be and the higher his achievements will be.

After the trial operation of the desalination channel, everyone divided into three groups.

Ma Chang went to report to the superiors; Yuan Quan, the factory director and others continued to test the desalination equipment to see if there was anything that needed improvement.

Zhu Jianguo and Fang Ping went to discuss the construction and layout of wind power stations.

…

In the scientific research area of ​​Shanmei Galaxy Technology, Huang Junjie is busy experimenting.

Suddenly the little secretary came in.

"Ajie, this is the report sent by Mr. Zhu from the water company."

Huang Junjie put down his work and took the report to read.

[The first phase of the Bohai Sea Desalination Project is in good trial operation. A single desalination canal can produce 28 billion cubic meters of fresh water per year... At full load, it can produce 84 billion cubic meters of fresh water per year...]

Seeing this, Huang Haojie raised the corners of his mouth and cheered for the water company's quick action:

"Good! Good! Very good! Now the greenhouses in the northern desert finally have water available, and I have an explanation for it."

He took out his mobile phone and dialed Zhu Jianguo's number.

"Boss!" Zhu Jianguo's voice came out immediately.

"Jianguo has done a good job. The water problem in the north has now been solved."

"Boss, there is no problem with the output of the desalination plant. Now the pipeline cannot transport so much fresh water!" Zhu Jianguo explained quickly.

Huang Haojie immediately realized when he thought about it. The annual water delivery capacity of that water pipeline is about 15 billion cubic meters, and the pipeline route is too single, which obviously cannot meet the water delivery requirements.

Currently, how much water do the five regions—Hebei Province, Mongolia District, Liaodong Province, Jin City, and Beiping City—need each year?

There are 18.1 billion cubic meters in Hebei Province, 18.5 billion cubic meters in Mongolia, 16.7 billion cubic meters in Liaodong Province, 2.7 billion cubic meters in Tianjin City, and 4.3 billion cubic meters in Peiping City. The five places have a total of 60.3 billion cubic meters of fresh water.

60.3 billion cubic meters, which means that the first phase can meet the water needs of Hebei Province, Mongolia Region, Liaodong Province, Tianjin City, and Beiping City.

"Well, our fresh water is more than enough to supply the five northern regions. Now everything is ready and all we need is the east wind."

After thinking for a while, Huang Haojie ordered:

"The water transmission pipeline will be built immediately. Pipelines leading to Hebei Province, Tianjin City and Beiping City will be built first. This fresh water is so important to the north. Ma Chang should help us solve this matter. After all, they own 70% of the shares of the water company. of."

"Yes, Mr. Ma has already gone to make arrangements."

"Okay, besides, the name of this project is too common, so let's change it to the Yellow River Reconstruction Project!"

In fact, the first phase of the desalination plant in the Bohai Sea District can actually be regarded as the title of "rebuilding the Yellow River".

Because the annual flow of the Yellow River is about 56 billion cubic meters, which is equivalent to the annual output of two desalination canals.

But the two are different, because the water from the Yellow River contains a lot of sand and cannot be used directly; while the fresh water from the desalination plant can be drank directly.

Soon after an intensive discussion with the water company, a general plan was reached.

It was decided to add two main water transmission pipelines, one is Line 2 supplying Hebei Province, Jin City, and Beiping City; the other is Line 3 supplying Liaodong Province.

Line 2 will be given priority to start construction, and Line 3 will be constructed in the second half of next year.

In addition, two new seawater desalination plants are planned to be built in the coastal areas of Lu Province in the Bohai District and the coastal areas of Su Province.

Judging from the blueprint, the first, second and third phases of the Yellow River Reconstruction Project are like three big trees. The desalination plant is the root, the water pipeline is the trunk and branches, and the cities along the line are like the leaves.
