Chapter 166 Rebuilding the Yellow River

8 month 11 day.

The seawater desalination plant of the first phase of the seawater desalination project in Bohai Sea was officially completed.

Zhu Jianguo, the president of Dongtang Yinhe Water Company, Ma Chang, the vice president, Yuan Quan, the director of the Seawater Desalination Research Institute who came here to guide the work, Fang Ping and Zhang Haifeng from Haifeng Wind Power, and others gathered together in the first phase of the seawater desalination plant in.

"Yuan Suo, can we do a trial run now?" Zhu Jianguo asked.

Yuan Quan nodded: "It's fine."

"Let's get started!" Zhu Jianguo ordered to the factory manager beside him.

The factory manager quickly ordered the workers to start the equipment of the seawater desalination plant according to the operation procedure.

The cross-section of the desalination reservoir of the seawater desalination plant is a trapezoid with a design length of one kilometer and a width of 50 meters.

Seawater desalination membranes are set on slopes on both sides. The length of the slopes is kilometers and the width is 20 meters. One side covers an area of ​​[-] square meters, and the two sides cover an area of ​​[-] square meters.

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

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

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

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

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

It is just one of the desalination canals currently in operation. This desalination canal alone can produce 280 billion cubic meters of fresh water a year.

A total of three desalination canals are planned for this seawater desalination plant, two for daily production and one for backup.

If the three desalination canals operate at full capacity, they can produce 840 billion cubic meters of fresh water a year.

Of course, full load is impossible. It is not that the desalination plant cannot produce, but that the transportation pipeline cannot transport so much fresh water.

The water pipeline currently being erected has a single-line annual water delivery capacity of 150 billion cubic meters.

If the desalination plant is operating at full capacity, six water pipelines with an annual capacity of 150 billion cubic meters are required.

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

The water level in front of this reservoir with an area of ​​30 square meters, a depth of 300 meters, and a capacity of [-] million cubic meters is rising at a speed visible to the naked eye.

Don't think that a 300 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 this reservoir.

So during the test run, only 40% of the power was activated, but even so, the reservoir would be completely filled in about two and a half hours.

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

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

Others picked up cups to fill water and drank.

"not bad!"

"I didn't feel the bitterness."

"It's almost like pure water."

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

"It's not that simple! The water delivery capacity of the water pipeline is a problem." Zhu Jianguo smiled wryly.

Everyone couldn't help laughing when they heard it. Now it's not the pipes waiting for the water, but the water and other pipes.

"Don't worry, Mr. Zhu. I'll report this issue to the higher-ups immediately. Since there is so much fresh water surplus, we can't let this production capacity be wasted here." Ma Chang said hastily.

"Then please trouble Mr. Ma."

"No trouble, it's all a matter of duty."

Ma Chang wished there would be more such things. After all, the more important the water company was, the higher his position would be and the higher his grades would be.

After the desalination canal was tested, the crowd split into three groups.

Ma Chang went to report to the higher authorities; Yuan Quan, the factory manager and others continued to test the condition of the desalination equipment to see if there was room for improvement.

Zhu Jianguo, Fang Ping and the others went to discuss the construction and layout of the wind power station.

……

In the scientific research area of ​​Shanmei Yinhe Technology, Huang Haojie is busy with experiments.

Suddenly the little secretary came in.

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

Huang Haojie put down the work in hand, took over the report and read it.

[The trial operation of the first phase of the seawater desalination project in the Bohai Sea area is in good condition. A single desalination canal can produce 280 billion cubic meters of fresh water per year... At full capacity, it can produce 840 billion cubic meters of fresh water per year...]
Seeing this, the corners of Huang Haojie's lips turned up, applauding the quick action of the water company:

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

He took out his mobile phone and called Zhu Jianguo.

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

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

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

When Huang Haojie thought about it, he immediately realized that the annual water delivery capacity of that water pipeline was about 150 billion cubic meters, and the pipeline was too single, obviously unable to meet the water delivery requirements.

At present, how much water do the five cities of Hebei Province, Mongolian District, Liaodong Province, Tianjin City, and Beiping City need in a year?
冀省181亿立方米、蒙区185亿立方米、辽东省167亿立方米、津市27亿立方米、北平市43亿立方米，五地一共603亿立方米淡水。

603 billion cubic meters, which means that the first phase can meet the water needs of the five cities of Hebei Province, Mongolian District, Liaodong Province, Tianjin City, and Beiping City.

"Well, our fresh water is more than enough to supply the five places in the north. Now everything is ready and we only owe the east wind."

After pondering for a while, Huang Haojie ordered:

"The water pipeline will be built immediately, and the pipelines leading to Hebei Province, Jin City and Beiping City will be built first. These fresh water are too 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, President Ma has made arrangements."

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

In fact, the first phase of seawater desalination plant in Bohai District can actually be called "reconstruction of the Yellow River".

Because the annual flow of the Yellow River is about 560 billion cubic meters, which is equivalent to the annual output of two desalination canals.

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

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

It was decided to add two main water pipelines, one to supply Line [-] of Hebei Province, Tianjin City, and Beiping City; the other to supply Line [-] of Liaodong Province.

Construction of Line [-] will be started first, and Line [-] will be constructed in the second half of next year.

In addition, it is planned to build two new seawater desalination plants in the coastal areas of Lu Province and Jiangsu Province in the Bohai Sea District.

From the blueprint of the plan, 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 route are like the leaves.
