Chapter 1179: Buy land!

"Xiao Xuan, the old man is here today, there is one more thing to discuss with

you!"

In the main hall, Li Zexuan, Li Jingmo, and Han Tianhu sat in sequence. Han Li

was taking a sip of tea and said sternly.

"Oh? Father-in-law, don't hesitate to say something!"

When Li Zexuan heard this, his spirits suddenly appeared.

In other words, since Han Lizheng returned from Yunzhou last year, Li Zexuan

felt that his father-in-law was like a different person. What happened to Han

Li in Yunzhou, Li Zexuan has no way of knowing. He asked, but Han Li is

avoiding it. Talk, he can't help it!

Now Han Lizheng said that he had something to discuss with Li Zexuan, and told

Li Zexuan intuitively that this might have something to do with Han Lizheng's

previous trip to Yunzhou.

At this moment, Han Li was silent for a moment, and said, "Xiaoxuan, you

opened five mines in Hedong Road last year. The old man went to see them one

by one. In general, each mine was brought to the surrounding people. This is a

great benefit, because the people can work in the mines and subsidize their

families! But as far as the old man knows, the mines have also brought a lot

of trouble to the people around!"

"Trouble? What's the trouble? Did someone have an accident in the mine?"

Li Zexuan frowned and subconsciously had some bad feelings, so he asked

quickly.

Father Li, who was on the side, also showed a trace of nervousness on his

face. Obviously he didn't want his son's life to be killed in the mine!

Seeing that the father and son had misunderstood, Han Li hurriedly waved his

hands and said, "No! No! The trouble that the old man said was that the dirty

water produced in the mine often flowed down the ditches and into the nearby

rivers or lakes. In this way, the people daily Drinking water will cause a lot

of trouble!

Last year, cholera occurred in Chang'an City. I heard from Xiaoxuan that the

main reason was that the water source was polluted! Now, the old man is

worried that the people around the mine may get sick if they use this polluted

water source for a long time! If you want to come to Xiaoxuan, you don't want

to see that kind of result, so the old man will say it and let you make plans!

"

Li Zexuan's heart moved. It turned out that there was a problem with sewage

discharge from the mine. At the same time, he couldn't help but praise his

father-in-law for being so careful that he could see the negative effects of

the mine on the environment forward-looking.

"Xuan'er, your father-in-law is right! This problem must be resolved as soon

as possible, otherwise it will be too late when something happens at the end!

And it will ruin your reputation!"

Father Li spoke out to help.

Li Zexuan nodded, and after pondering for a moment, he said: "This is indeed a

problem. Father-in-law and my son-in-law have a way. Although it is a bit more

troublesome, it can solve the water problem of the people around the mine!"

Han Li's eyes lit up and he said excitedly: "Xiaoxuan, do you have a way?

Great! You can talk and listen!"

Li Zexuan narrowed his eyebrows and said, "Xiaohe, get paper and pen!"

"Okay! Master!"

Xiaohe’s promise came from outside. After a while, the little maid brought a

piece of white paper and a pencil. Li Zexuan took it, spread the paper on the

table, and said while drawing:

"First of all, a sewage treatment pond must be dug between the major mines and

the rivers and lakes. The terrain of the sewage pond must be higher than that

of the river. The outlet of the sewage pond must be set up with one after

another special dams. This dam is filled with gravel and charcoal. After the

sewage from the mine enters the cesspool, it passes through one gravel **

and then discharges into the river, it will no longer pollute the water source

in the river!"

This method is actually called the biofilm method in modern times. Since

sewage flows continuously through the solid filler, a sludge-like biofilm will

be formed on the filler. A large number of microorganisms multiply in the

biofilm, and the microorganisms will release protein during the growth

process. It can convert the soluble heavy metal ions in the sewage into

sediments and remove them, thereby purifying the sewage.

This is the least laborious and feasible sewage treatment method Li Zexuan can

currently think of.

"Xuan'er, is this possible? What if the local water source is still polluted

by the time?"

When Father Li listened, some of them were believing.

Li Zexuan waved his hand and said, "Father, don't worry! This method

definitely works!"

Han Li was staring at the manuscript previously drawn by Li Zexuan, frowning,

and said: "Xiaoxuan, if you want to build this sewage pond, it will take a lot

of manpower and material resources, right? Not only that, this sewage pond

also takes up a lot of space! Is it worth it to do this so aggressively?"

He is the one who proposes to treat the sewage, and he is the one who feels

that it is too exhausting for the people and money! It is not that Han Li is

hypocritical, but that he wants to solve the sewage problem without adding too

much cost burden to Li Zexuan!

But how can there be such a perfect thing in the world?

"Father-in-law! This matter is not a question of whether it is worth it or

not, but a question of whether to do it or not! If we do

nothing~www.mtlnovel.com~ waiting for the water source to be polluted by the

sewage from the mine, then 100 years later, even After a thousand years, will

our descendants not even drink a drop of clean water? So, for our children and

grandchildren, we must take the lead in doing this!"

There is no concept of environmental protection in this era, but Li Zexuan

hopes that he, Datang’s largest private mine owner, can set an example for

those mine owners behind him, and wait until others later become mine owners,

more or less. Will notice environmental problems!

"Okay! The old man is relieved with your words! After a few days, the old man

will leave for Hedong Road and urge all mine owners to step up preparations

for this sewage treatment pond!"

Hearing what Li Zexuan said was really serious, Han Li nodded solemnly and

said.

"By the way! Father-in-law! How many Zhuangzi are the closest to the five

mines of my son-in-law?"

Li Zexuan suddenly smelled it.

Han Li didn't know why, but still replied, "There are three, what's wrong?"

Li Zexuan smiled, and then said: "Three Zhuangzi? That's good! My son-in-law

plans to pay for the three Zhuangzi, and then give it to his father-in-law,

how will your old man go to manage these three Zhuangzi? "

Han Li was startled, and quickly waved his hand: "No, no! Xiaoxuan, why is

this a good way to buy Zhuangzi? Even if you really want to buy it, it's for

you, why do you have to send it to the old man?"

Li Zexuan explained: "Hehe! Father-in-law, listen to me slowly. These

villagers are very close to the mine. What pollution is the mine? They are the

first to suffer! If pollution is to be controlled later, these three must be

dealt with. Zhuangzi carries out a large-scale transformation! In this case,

the best way is to buy all of these Zhuangzi first! And under the name of my

son-in-law, there are now eight large Zhuangzi, and they cannot expand any

more! So only I can give these three Zhuangzi to your father-in-law!"

Second!
