Chapter 636: Visiting the Waterworks

It didn't take long for Qin An to take everyone to a fitting room, which was the place where the staff changed their clothes.

Two security guards were already waiting.

"Village Chief, sir, the clothes and shoe covers are here." A security guard said.

Qin An said, "Okay, you go back to work, don't let people sneak in."

"No." The two security guards immediately left in a hurry.

They feel that their lifespan is one day less when they stay here for one more second, and they are already under a lot of pressure in the face of a group of big guys, not to mention the big guy among the big guys, the first emperor Yingzheng, which makes them breathless.

The so-called clothes are white coats, and wearing them on the body is to let people know that they are clean and tidy.

Qin An picked up a white coat and demonstrated it to everyone, followed by shoe covers, and everyone learned in style.

After Qin An put it on himself, he helped Ying Zheng and the others put on the white coat.

Once everyone is dressed, it's time to go inside the real waterworks.

On the way, Meng Sheng and Gong Yang looked at this waterworks, and couldn't help but be shocked, and at the same time felt very sorry, because they didn't participate in it.

"Sir, we've been in the village for a few months, why didn't we know anything about the waterworks when we built it?" Meng Sheng said.

Qin An rolled his eyes and said, "I'm embarrassed to say that the two of you have been studying the harvesting cart with the cuttlefish, and you haven't shown your face once.

I'm afraid this appearance is also because my father-in-law is here."

Meng Sheng and the male loser suddenly looked embarrassed, indeed, as Qin An said, they hadn't shown up for several months.

It's not that they don't want to show up, it's that damn self-esteem and face that make them not want to show up.

This time, I studied with a group of disciples such as cuttlefish, and found that the disciples' eyes on Qin An's worship were better than the two of them.

This made the two of them feel very uncomfortable, a little jealous, as if something important had been robbed.

So in order to maintain their poor self-esteem and dignity in front of their disciples, they have been studying steam harvesters with their disciples.

Even if they encountered difficulties, they didn't ask Qin An, just like that, according to Qin An's suggestion and cuttlefish's drawings, they simply drew the complete drawings of the steam harvester.

Now it's just a matter of making it and experimenting.

But they want to talk about it after the experiment is successful, and they don't plan to make it public yet.

Ying Zheng glanced at them and said, "How is the harvester researched?"

"Return to the village chief." "The drawings have been redesigned, and now we just have to wait for them to be made and experimented.

We want to wait until the experiment is successful before reporting to the village chief."

Ying Zheng nodded and said, "I and the people of ten miles and eight towns are waiting for your good news.

Qin An, let's take us around the waterworks first."

Qin An said, "Walking forward is the raw water inlet, which is also the real entrance of the waterworks, which is responsible for receiving water from rivers, lakes, groundwater and other water sources.

After the initial treatment, the raw water is fed into the subsequent water treatment system."

Everyone soon came to the entrance of the raw water, and saw that the raw water continued to enter the waterway, like a silver snake running wildly.

Meng Sheng saw the grille not far away and asked, "Sir, what is that for?"

Qin An smiled, "It is a filtration equipment used to remove suspended solids, impurities and large particles of impurities in the raw water.

Because this grid is artificial, it has to be replaced basically every day to keep the water clean and avoid being blocked and the water source cannot enter the sedimentation tank."

"Sedimentation tank?" Ying Zheng said, "Is there anything that needs to be precipitated with such clean water?"

"Father-in-law, although he can intercept suspended solids, debris and large particles of impurities, it does not mean that he can block everything, so the sedimentation tank is a must

To prepare.

It can further remove impurities such as suspended solids, sediment and other impurities in the raw water. Through natural precipitation or chemical precipitation, the suspended solids in the water settle to the bottom of the pool, so as to achieve the purpose of purifying water quality.

But don't think that the unclean stuff is ready to drink after it has been settled in the sedimentation tank."

"Why can't you do it?" Guiguzi asked.

Qin An said, "Of course not, there are a lot of microorganisms in the water, these microorganisms are not good things for the human body, just drinking it like this, there is a high probability that it will make you have worms in your stomach."

Medically known as parasites.

And people who have parasites will have stomach pain and swelling for no reason, and sometimes pull out worms. It could even be fatal."

Everyone was shocked, they didn't expect that there was such a terrible thing in the water, and if it was drunk into the stomach, no one knew if there were parasites in the stomach.

"What should I do if I get parasitic disease?"

"See a doctor, take medicine." Qin An replied simply.

"What medicine?"

"This really stumped me, when I was a child, I had parasitic diseases because I didn't eat and didn't wash my hands, and I only knew that the doctor prescribed medicine for me, but I didn't know what medicine I was dispensing.

And you can't take too much of this medicine, too much of it will poison people, oh, I remember, it's arsenic." Qin An said.

"What?"

Everyone was taken aback again, and this time even Guiguzi and Huangshi changed their faces.

Guiguzi said, "Qin An, do you know that arsenic is a highly poisonous thing?"

Qin An said, "Of course I know, but eating a certain amount will not poison people, it will only poison the parasites in the stomach.

Don't worry, I've done a lot of experiments on this, and I've eaten it, haven't I lived well.

If you don't believe it, you can ask Lao Xia to find a group of patients with parasites in their stomachs, and then feed them arsenic.

I don't know if there were any other herbs in there at that time, I didn't study medicine."

Ying Zheng bowed his head and said, "I'll do this thing, let's continue to look at the next area."

"The next area is the Bioprocessing Zone." Qin An said.

Later, under the leadership of Qin An, he went to the biological treatment area, and at the same time, under Qin An's explanation, he knew the importance of this biological treatment area.

Then, Qin An took everyone to the advanced treatment area, water outlet, sludge treatment area and other places.

Finally, Qin An also took everyone to visit the auxiliary facilities area, so that everyone knew that the waterworks are also equipped with some auxiliary facilities, such as office buildings, laboratories, maintenance workshops, warehouses, etc., to meet the needs of production, management and operation.

For a waterworks, Qin An and they spent most of the day.

However, this waterworks also shocked Yingzheng and them, it turned out that all the pipes used to transport tap water were bought underneath and the quality was very good.
