Chapter 426 The bitter taste of the salt pond in Hedong

……………………………………

The amount of slag produced in the smelting process is very large, and if you want to get a ton of pig iron, you will produce about a ton of slag at the same time, and if you want to get a ton of copper, you can even produce five or six tons of slag. Year after year, day after day, if the slag is piled up in one place, the highest peak of the world may become the "slag peak", and I don't know if this is a miracle created by mankind.

Fortunately, Liu Hanshao comes from an era of environmental protection, although he doesn't know much about slag, but he has heard of slag bricks. "It's the same scum at the end of the world, why should we have known each other when we meet." When he was in Luoyang before, Liu Hanshao noticed this problem, whether it is casting, forging, glass, ceramics, as long as coal is used for fire, a large amount of slag will be produced. Then let Liu Zi lead the team to research and make slag cement bricks.

Speaking of which, this thing is easy to do now, that is, it uses slag instead of stones, and after crushing evenly, it is mixed with sand and cement to make cement bricks. Anyway, it is paved on the road, as long as it is strong, and there are no strict standards. But Liu Hanshao is not satisfied, because he also knows that it seems that the slag itself can be used as a raw material for making cement, as well as the hollow bricks made of slag, as well as the environmental protection filtration function of the slag, similar to bamboo charcoal, if there is wastewater filtered by the slag, it can greatly reduce the harmful substances in it.

Of course, there are many other uses for slag, such as making phosphate fertilizer, insulation materials or something, but this is no longer something that slag can know, but this does not prevent him from giving an order to let Liu Zi lead the team to specialize in slag. Poor Liu Zi burned the broken clay jar, burned the floor tiles, burned the cement and burned the toilet, and finally burned himself into a pile of slag.

"Slag water filtration" is a big project, industrial wastewater, urban wastewater after precipitation, filtration, and then discharge into the river waterway, how to determine whether it has reached the standard? Dig another pond behind the filter pond and keep fish in it, and as long as the fish don't die, the water should be a problem.

In addition, there is a biogas digester project, whether to separate the municipal manure from other sewage, or to build a biogas digester nearby? Will there be a safety hazard to build this thing in a densely populated city? It is impossible to use it instead of coal for large-scale heavy industry, and it is okay for small light factories and wealthy people to use it. It should be piloted in the suburbs, away from crowded areas.

And all of this, in addition to continuous research and experiments, what is needed most is money, since Min Gong has a lot of money to build a small field for Liu Hanshao, then it is the best thing to put these money-burning experiments in Hanoi.

…………

After leaving Hanoi, Liu Hanshao did not go north to Shangdang, but went west to Hedong, not only to see the steel mills in Hedong, but also the Hukou Canal built by the Ministry of Water Resources.

Now Gao Jie is the head of the military department of the Han Zheng Army, Wu Kuang took over the post of commander of the First Army, and Wu Kuang was replaced by Liu Pi's deputy, Shi Lian. The three counties of Hanoi, Hedong, and Shangdang were all defense areas of the First Division, so since Liu Hanshao crossed the river, Shi Jian reported to the Supreme Commander, accompanied him throughout the process, and arranged for the soldiers and horses of the outer guards.

After Liu Hanshao arrived in Hedong, Wang Yi, who succeeded Huang Shao as the magistrate of Hedong, led his subordinate officials to greet him, and the entourage was nearly 10,000 people. Liu Han was suspicious of the mobilization of the army and the loss of money and money, so he ordered Shi Jian and Wang Yi to withdraw most of the guards

followed, and criticized them "harshly", not to be so unprofessional.

Before, Huang Shao, Wu Kuang, and Han Hao first killed people in Hedong in order to avenge Liu Pi, and later Wang Yun went to Taiyuan to sit in the town, transferred Taihang immigrants, and cleaned up a group of powerful households, so Hedong and Taiyuan always think that the imperial court is too strong, and there is no grace, although they dare not say anything strange, but they are still very dissatisfied in their hearts.

After Beidi Wangyi took over as the magistrate of Hedong, he implemented a pacification policy, and tried his best to help those seriously damaged famous families in Hedong find a new way out within the framework of the law. If there is no land, you can still open factories, and if you have fewer slaves, you can still hire workers, and even if you organize people to transport steel and coal from Hedong to Hanoi, you can make a lot of money. In the treatment of ordinary people, in addition to dividing the land and resolutely collecting more taxes and rents, they are also encouraged to raise poultry and livestock, go out to help during the slack season, and even develop special agricultural products on a large scale.

For example, Guan Yu's hometown of Xie County used to plant a lot of jujube trees, and when the people had no food to eat, they could only pick jujube trees to satisfy their hunger. And now Wang Yi has a plan to encourage the people to plant a variety of jujube trees, because the former Xie County jujube has been a tribute, the fruit is huge, the color is purple and red, the skin is thin and the flesh is thick, the core is small and sweet, and the high-achieving students dug from Luoyang Agricultural College also said that this kind of jujube can nourish qi and blood, nourish the heart and lungs, and is a high-grade fruit. Now the emperor doesn't want to pay tribute, let's plant the jujube and sell it to those rich people in Luoyang and Hanoi, which will definitely make a lot more money than growing grain.

And then there's Wenxi's persimmon, everyone knows that this thing can be made into vinegar, right? But you can still make wine, you know? It can also be made into persimmons, hung with thick icing, and when you bite into it, the taste is called beautiful.

This is the way to enrich the people!

It is with such efforts that Wang Yi has been unanimously recognized by the whole of Hedong, and his prestige is getting higher and higher. Who would have thought that the emperor criticized it first when he came.

This one...... You are the emperor's brother, let's not bring more people to greet you, it's not that I am afraid of not respecting you enough.

Of course, this is just a joke between the monarch and the minister, Liu Hanshao is still very satisfied with Wang Yi's governance methods, and told them that they can grow fungus and mushrooms in the shady place behind the mountain, and build a pond near the river to raise fish, that is, to dare to be eclectic and make a fortune.

…………

Hedong "Salt Pond" is the oldest and most famous salt lake in the Han Dynasty, the legend of the Yellow Emperor vs. Chiyou, this place is the place where Chiyou's head is decomposed, so it is also called "Jiechi", and the salt produced is also called "Jieyan".

There is also a legend that in order to compete for the salt pond in Hedong, the Yellow Emperor fought two wars with Chiyou and Yandi, which are the famous "Battle of Zhuolu" and "Battle of Hanquan" in history. The victory of these two wars made the Yellow Emperor firmly control the salt pond in Hedong and the salt lifeline in the Central Plains, and finally became the leader of various tribes and obtained the lofty status of "the ancestor of China".

Of course, the credibility of the legend depends on whether people are happy or not, but it is not an exaggeration to say that salt is the "lifeblood" of daily life, otherwise the successive dynasties would not have strictly managed salt, or extracted heavy taxes, or court officials. In the past, Emperor Wu of the Han Dynasty set up salt and iron as an official camp, and private salt production was punishable by imprisonment, which not only required a large amount of money to support Emperor Wu of the Han Dynasty's ambition to conquer, but also to prevent the flow of salt and iron to the northern Xiongnu. Later, with the strength of the imperial court,

This system was also intermittent, and after the emperor, it was completely abolished, allowing private salt to be sold and taxed by the imperial court. However, the people still can't eat cheap salt, in addition to the heavy taxes of the imperial court and the huge profits of salt merchants, the inconvenience of transportation is also an important reason.

Liu Hanshao took Yun Liuniu, Ren Hongchang and Cao Cao and others to walk on the bank of the salt field, originally Yun Liuniu thought that the salt field should be as white as snow, but he thought that the salt lake was brown and red, and the color in the salt field was even different shades, and even red purple, only the salt pile that had been piled up in the middle was crystal clear.

Such a colorful scene made Yun Liuniu excited, and Wang Yi also explained on the side that this is Chiyou blood, which was decomposed here in the past, and the aura in the blood gathered but did not disperse, and the lake would be red in summer. Everyone listened to the magic, but Liu Hanshao was a black line in his head.

The discoloration of the salt lake is due to the fact that in summer, a large amount of water evaporates, which increases the concentration of potassium and sodium in the lake water, but it is unevenly distributed, so that some areas can change color heavily, and some areas can change color lightly. In addition, there is a salt algae growing in the salt lake, which is normally green, but when the growing conditions are poor, heme is produced, which turns the algae red, so the lake water will look green and red. The turquoise water of the lake is not unusual, but the red water of the lake can turn people beautiful, so it is also called "Rose Lake".

It's a pity that the scumbag probably knew what was going on, but he couldn't say it clearly, so he could only pull Yun Liuniu over and whisper in his ear: "Don't listen to Lao Wang's nonsense!" ”

Yun Liuniu is humble and studious, Liu Hanshao knows nothing, and the two of them stay away from everyone and mutter, making Ren Hongchang, who is far away, both envious and disappointed.

Just as there must be grains of wheat next to the wheat field, the salt pans are all grayish and white, as if the soil also contains a lot of salt grains. Cao Cao grabbed a handful, sniffed it, rubbed it, and then said with emotion: "Your Majesty is right, Hedong is really a treasure house, and salt production alone can make huge profits, not to mention steel and coal." If the people are poor, they can grab a handful of clay and boil it to make brine, which can also be eaten as salt. "TV Mobile/

Wang Yi hurriedly responded: "Minister Cao said with a smile. If there is no salt, how can the poor people come to Hedong to boil brine? It's just that the salt produced in Hedong is salty and bitter, and it is not of the highest quality, even if there is salt, it is not suitable to eat more. ”

Is it bitter?

Hearing this, Liu Han ordered someone to go to the salt field to bring some salt cubes, and tasted it, and it was really salty with bitterness, bitterness with astringency. Look at the salt cube in your hand, it is crystal clear, but there are a lot of impurities in it.

Liu Hanshao asked in surprise: "Just eat it directly?" ”

Yun Liuniu was afraid that her husband would be stupid, so she hurriedly said: "This is salt, how can you eat it directly?" Just put a little bit in when cooking. ”

Foul words, have you forgotten that your husband can also cook?

"It's not. Brother means to ask, what to do with the mud and sand grains in this salt? ”

Wang Yi explained: "When you eat it, you will smash the salt cubes, turn them into water, and sink the sediment. And this is just the method used by wealthy families, if ordinary people can get food and clothing and are already satisfied, who cares about a little sediment in the salt? ”

No, my brother is a person who has been in the kitchen, even if he learns scum, he can't make a joke of "why not eat minced meat", right? But the salt my brother used really didn't look like this.

"Second baby, second baby!"
