Zhu Shun was also waiting for the construction of this waterworks, riding on the Liaodong horse, Li Zhouqiao and others rode a little donkey and went to the construction site of the waterworks together.

The most important thing in the waterworks is the water source, and you must choose a clean water source.

Jingxi is located at the junction of the Taihang Mountains and the Pingchuan River, the Taihang Mountains as a huge mountain range that divides the Ming Dynasty into east and west, vast and boundless, the west and north of Jingxi are mostly mountains and hills, accounting for about two-thirds of the western part of Beijing.

A few miles away on the western outskirts of the industrial city are the rolling verdant mountains and verdant hills, undulating, lush with flowers and trees, and sweet mountain springs.

The water source of the waterworks is in a valley three miles away, which is the source of the Liuli River, which flows through Hejian and Baoding, and finally flows into Baiyangdian in Baoding in the south.

Zhu Shun rode a Liaodong horse to the western suburbs of the industrial city, and there were continuous cyan peaks in front of him.

The valley is not long, and after walking for more than a hundred meters, I saw a clear river flowing in the mountains, flowing south.

The end of the valley was not suitable for horseback riding, so Zhu Shun and the others walked over and came to the bank of the clear river.

Fifty meters from the shore, a pool was excavated.

Because it is a mountainous area, there are many stones in the soil, and it is difficult to excavate, so the pond is basically blown out with gunpowder and then repaired manually.

The group walked to the pool where there was no water, and Li Zhouqiao introduced: "At the head of the meeting, the waterworks is composed of four parts, a filter tank, a sedimentation tank, a reservoir, and an elevated water tower. ”

"This pond is a filter pond, and the clear Liuli River water enters the filter pond through a concrete pipe three meters below the water level."

"The bottom of the filter tank is composed of small stones, coarse sand and fine sand to form a filter bed, the filter bed is divided into two layers, the lower layer is fine sand to filter small particles, and the upper layer is paved with small stones and coarse sand to filter large particles."

"With these two layers of filter beds, we can basically filter out impurities in the water."

After introducing the filter tank here, Li Zhouqiao led the group to the sedimentation tank next to it: "This is the sedimentation tank. ”

"The water in the filter tank will flow through the water pipe at the bottom to this low-lying sedimentation tank, where it will settle the sediment that may be in the water."

The filtration tank and sedimentation tank are located in the valley, and the remaining two parts, the reservoir and the elevated water tower, are located in the lower lying areas.

Through the introduction of Li Zhou Bridge, Zhu Shun had a general understanding of the reservoir and elevated water tower structure designed by the Infrastructure Construction Department.

There is also a water pipe in the sedimentation tank, and in the middle of the side wall of the sedimentation tank, this wide water pipe, with concrete on the outside and a wooden pipe in the middle, flows into the reservoir.

The structure of the cistern resembles a deep well, but it is very different, the general well is a cylindrical structure straight up and down, and the cistern structure is a triangular structure.

It gets narrower and narrower as it goes up, and is finally sealed with a cement lid with a pipe in the middle that pumps clean clean water through a steam engine to an elevated water tower.

In order to ensure the draft of millions of people at the metropolitan level in the future, a total of nine such permeable corridor water supply systems will be built, one in each district.

There is also an elevated water tower in the middle of each district, which is connected to the elevated water tower in the valley by pipes, and there are a large number of small pipes on the outside to carry clean water to each house.

This year's plan is to build the eastern area connected to the cement factory.

An eastern district is already equivalent to a county seat that can accommodate more than 100,000 people, and whether it can be successfully built this year is still a question, so a set of infiltration corridor water supply system has been built for the time being.

This permeable corridor water supply system is already very complete and does not need to be modified.

Zhu Shun watched very carefully, after all, when it comes to the domestic water of the future industrial city, he has to be careful: "There is no problem with the water supply system of the waterworks, but there are two points that you have not considered. ”

Hearing that Zhu Shun was about to give instructions, Li Zhouqiao and the genius students hurriedly took out charcoal pens and scrolls, ready to record them.

Zhu Shun pointed to the elevated water tower that had already begun to build the frame and said: "Water purification and ozone sterilization. ”

"This is the water source of the Liuli River, and there is no pollution, which is the highest level of water source."

"After this set of permeable corridor water supply system purification, it seems to be very clean, but there are still some invisible things in the water quality."

"That's when the water needs to be purified and ozone sterilized."

"Water purification is easy to solve, just use alum, but this ozone sterilization."

When it comes to ozone sterilization, Zhu Shun is also a little difficult, not that there are no sterilization methods, but those methods have reached the ceiling of the current industrial level.

There are two main methods of sterilization, one is to use high-frequency electronic devices to generate ozone to sterilize tap water, and the other is to sterilize with chlorine.

The high-pressure steam engine has not yet been invented, let alone steam power generation, or even high-frequency electronics.

There is no need to think about chlorine, the industrial level can make chlorine, and Zhu Shun can sell refrigerators and air conditioners in the Ming Dynasty.

However, it can be solved in the most primitive way.

Zhu Shun thought for a while and continued: "The accumulated salary is already researching coal washing, as long as it is researched, a large number of briquettes can be produced, and the price of firewood for opening the door will definitely fall sharply." ”

"In addition, the trade of briquettes will also give workers certain discounts, and when the time comes, the workers should ensure that they have the habit of drinking hot water."

Zhu Shun knows very well that China's unique habit of drinking hot water is one of the important reasons why the physical condition of Chinese people is much better than that of other European and American countries.

After the founding of the People's Republic of China, the three magic weapons to improve the life expectancy of the people, cool white water, antibiotics, barefoot doctors, hot water is not only one of them, but also ranked first, enough to see the importance of hot water.

It's not that people in the Ming Dynasty don't want to drink hot water, but the cost is too high, and ordinary people will have the luxury of burning hot water with charcoal at home, basically drinking cold water directly when they are thirsty.

Li Zhouqiao, who was born in poverty, mentioned the word firewood and sighed a lot: "Firewood for opening the door for seven things is really important, even more than food." ”

"The head of the meeting may not know that there are often fights in the countryside because of the competition for firewood, and one of the students' uncles died in a fight for firewood."

However, when it came to Xu Jixin, Li Zhouqiao's face showed a smile, and he admired this No. 1 talent in the capital very much.

The current Jingshi University Hall is also very famous in the capital.

Bo Jue, the first beautiful man in Beijing, Huang Zongxi, the first genius in Beijing, and Xu Jixin, the first genius in Beijing, are all in Beijing Normal University, and it is difficult to think of being famous.
