Chapter 636 Visiting the Water Plant
Not long after, Qin An took everyone to a fitting room, where the staff changed their clothes.
Two security guards were already waiting.
"Village chief, sir, the clothes and shoe covers are all here." A security guard said.
Qin An said: "Okay, you go back to work, don't let anyone sneak in."
"No." The two security guards immediately left in a hurry.
If they stay here for a second longer, they will feel that their life span has been shortened by one day. They are already under a lot of pressure facing a group of big bosses, not to mention the boss of the bosses, the First Emperor Ying Zheng, which makes them unable to breathe. Angry.
The so-called clothes are white coats. Wearing them lets others know that you are clean and tidy.
Qin An picked up a white coat and demonstrated it to everyone, followed by shoe covers, and everyone started to learn in style.
After Qin An finished dressing himself, he helped Ying Zheng and others put on their white coats.
Once everyone was dressed, we began to enter the real inside of the waterworks.
On the way, Meng Sheng and Gong Shuyang looked at the water plant and couldn't help being shocked. At the same time, they felt very sorry because they were not involved in the process.
"Sir, we have been in the village for several months. Why were neither of us aware of the construction of this water plant?" Meng Sheng said.
Qin An rolled his eyes and said, "It's embarrassing to say that you two have been studying the harvesting truck with Cuiyu and the others, and you haven't shown your face even once.
I'm afraid this appearance is also because my father-in-law is here. "
Meng Sheng and Gong Shuyang suddenly looked embarrassed. Indeed, as Qin An said, they had not shown up for several months.
It’s not that they don’t want to show up, it’s their damn pride and face that makes them not want to show up.
This time, I studied with a group of disciples such as Cuyu and found that the disciples admired Qin An more than the two of them.
This made the two of them feel very uncomfortable and 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 harvesting vehicles with their disciples.
Even if they encountered difficulties, they did not ask Qin An for advice. Just like that, based on Qin An's suggestions and Cuttlefish's drawings, they just drew the complete drawing of the steam harvesting truck.
Now it's just a matter of making it and experimenting.
But they plan to tell them 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 research on the harvesting vehicle going?"
"Report back to the village chief." Gong Shuyang said, "The drawings have been redesigned. Now we are just waiting for them to be produced and tested.
We want to wait until the experiment is successful before reporting to the village chief. "
Ying Zheng nodded and said, "I and the people from all over the country are waiting for your good news.
Qin An, please take us to visit the water plant first. "
Qin An nodded and said: "Going forward is the raw water entrance. This is also the real entrance of the water plant, responsible for receiving water from rivers, lakes, groundwater and other water sources.
After preliminary treatment, the raw water enters the subsequent water treatment system. "
Everyone soon arrived at the entrance of the raw water, and saw the raw water continuously entering 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 and said: "That is a filtration equipment, used to remove suspended solids, debris and large impurities in raw water.
Because this grille is an artificial grille, it basically needs to be replaced every day in order to keep the water quality clean and avoid being blocked and preventing the water from entering the sedimentation tank. "
"Sedimentation tank?" Ying Zheng said, "With such clean water, is there anything that needs to be settled?"
"Father-in-law, although it can intercept suspended solids, debris and large impurities, it does not mean that it can block everything, so a sedimentation tank is a must.
Be prepared.
It can further remove suspended solids, sediment and other impurities in raw water. Through natural precipitation or chemical precipitation, suspended solids in the water settle to the bottom of the pool, thereby achieving the purpose of purifying water quality.
But don’t think that those unclean things can be drunk after settling in the sedimentation tank. "
"Why not?" Guiguzi asked.
Qin An nodded and said: "Of course not. There are many microorganisms in the water. These microorganisms are not good for the human body. If you drink it like this, there is a high probability that you will get bugs in your stomach.
Medically called parasites.
People with parasites will have unexplained pain and swelling in their stomachs, and sometimes they may pull out worms. It may even cause death. "
Everyone was shocked. They did not expect that there was such a terrifying thing in the water. If this was drunk into the stomach, no one would know whether there were parasites in the stomach.
"What should I do if I get a parasitic disease?"
"See a doctor and take medicine." Qin An replied simply.
"What medicine should I take?"
"This is really confusing to me. When I was a child, I had parasitic diseases because I didn't eat or wash my hands when I was eating. At that time, I only knew that the doctor prescribed medicine for me, but I didn't know what medicine was given.
And don’t take too much of this medicine, as it will poison you if you take it too much. Oh, I remembered, it’s arsenic. Qin An said.
"What?"
Everyone was shocked again, this time even Guiguzi and Huangshi changed their expressions.
Guiguzi said: "Qin An, do you know that arsenic is highly poisonous?"
Qin An said: "Of course I know, but if you eat it in a certain amount, it won't poison you, it will only poison the parasites in your stomach.
Don’t worry, many experiments have been done on this, and I’ve also eaten it. Aren’t I living 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 medicinal materials in it at that time. I'm not a medical student. "
Ying Zheng nodded and said, "I will take care of this matter. Let's continue looking at the next area."
"The next area is the biological treatment area." Qin An said.
Later, Qin An led us to the biological treatment area. At the same time, under Qin An's explanation, we learned 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 and let everyone know that the water plant is also equipped with some auxiliary facilities, such as office buildings, laboratories, maintenance workshops, warehouses, etc., to meet the needs of production, management and operation.
It took Qin An and the others most of a day to build just one water plant.
However, this water plant also shocked Ying Zheng and the others. It turned out that all the pipes for transporting tap water were bought from the underground and the quality was very good.
