Yan Shiyue was not polite, and directly in front of them, he instructed Ding Xiaoyan to prepare limestone and white coal quickly, and then took the two of them to the study and called the fourth prince: "Fourth brother, I said you write." ”

The fourth prince was very proactive, and immediately rolled up his sleeves to polish the ink and lift the pen.

Yan Shiyue tried hard to recall, and then integrated the knowledge in his mind before saying: "In a flooded place, the most important thing is to prevent all kinds of epidemics, so we must pay attention to disinfection." ”

Disinfection needs to be bleached, the main ingredient of bleaching is calcium hypochlorite, calcium hypochlorite preparation, limestone and white coal, according to the ratio of 1: (0.11~0.13) intermittently from the top of the lime kiln, added to the lime kiln for calcination, the temperature needs to be controlled at 800 ~ 1200 °C. The generated lime is discharged intermittently from the bottom of the kiln, and it is digested with water to obtain slaked lime containing a small amount of free water, which is aged for more than eight days, and sent to the winnowing system for slag removal by the auger.

The powdered slaked lime is separated by a cyclone for gas-solid phase separation. The fine-grained slaked lime containing 3%~6% free water is added from the fourth layer of the chlorination tower through the auger under the slaked lime silo, the first layer of the chlorination tower is passed, and the bleached finished product is discharged from the first layer of the chlorination tower (1).

This process, for this era, is very complicated, a lot of equipment needs to be researched and produced, even if it is urgent, it will not be possible to get it out in ten days and half a month.

So, at present, you can first sterilize with a simple, boiling boil.

Then, remember that the disease comes from the mouth, for example, do not eat drowned animals, do not eat stagnant food, and do not drink unboiled water...... Wait a minute. This can be directly made up and sung by the people.

In addition, disinfection of feces and corpses, as well as mosquito, fly and rodent eradication after the disaster, are also top priorities.

She said a lot and messily, the fourth prince finished remembering, and exchanged glances with the prince, and both of them were in a somewhat complicated mood.

Really, Princess Fuyan has never been expected, nor has she ever disappointed.

Disaster relief, who calls the civil and military officials, is also the first priority to control the water, such as the reinforcement of embankments, the diversion of rivers, and second, it is naturally an epidemic, take the imperial doctor to go, how to treat it, and then appease the people......

But what she is talking about is "prevention", the prevention and control of epidemics.

The prince groaned slightly.

The fourth prince took another piece of paper to tidy up. Witnessing the miracle for the first time, his expression was vaguely excited: "Anything else?" ”

Yan Shiyue thought carefully.

The first thing that comes to her mind is always modern disaster relief methods.

But the ancients did not have any merit in disaster relief?

Yes, of course.

Fan Zhongyan, a famous minister of the Northern Song Dynasty, took several measures for disaster relief back then, which was very courageous and ingenious.

For example, he was the first to propose "cash-for-work".

She has always been very much in agreement with this idea, and she has also talked to the four princes.

Moreover, he also encouraged the local community to hold more events, and he himself took the lead in participating and encouraging them. At the same time, he also summoned the chairmen of the monasteries and told them that during the famine years, the wages were the lowest, and the monasteries could take advantage of the opportunity to renovate the monasteries.

The hosts thought so, so they seized this rare opportunity to recruit the homeless people to come and work, only giving a very small amount of wages and providing three meals a day, and the homeless people flocked to it.

The government, businessmen, and wealthy families also saw a good opportunity and built a large number of buildings, so that the victims had food to eat and something to do, and the situation was naturally stable.

In addition, when this time comes, there is not enough food for disaster relief, and those profiteers who raise prices, hoard goods, and want to make a fortune in the country will always be indispensable.

He asked people to spread the word in the surrounding states and counties, saying that now the price of rice in Wuzhong is 180 wen per bucket, and those who want to make a fortune should come quickly!

When the merchants from other places saw that it was profitable, how could they not be tempted, and immediately organized a large amount of grain to be transported over.

After countless grains were brought in, they competed with each other to lower prices, and the market levers began to come into play, and the stubbornly high grain prices immediately fell, which not only solved the suffering of food shortage in the disaster areas, but also dealt a severe blow to those profiteers who tried in vain to make a fortune in vain.

What she said was still a little messy, but the crown prince and the fourth prince were already shocked and speechless.

You must know that a talented person may not be an official.

In this era, there are really few people who understand the economy.

Fan Zhongyan's economic thinking, at that time, was also impeached by countless people, accusing him of not being sympathetic to the wasteful government, and indulging in frolicking and amusement at the time of the disaster, building a large number of buildings, working the people and losing money, and so on.

Including the crown prince and the fourth prince, it sounded a little confused at first glance.

But when she directly clarified her thoughts and said the results that would be, the crown prince and the fourth prince were not stupid, so they naturally understood.

understood, and only admiration remained.

Then Yan Shiyue was carried into the palace by the two, and Emperor Ming Yan couldn't help but be shocked when he heard the two of them say it carefully.

Not to mention this "disinfectant powder", this follow-up measure has great wisdom.

The key to raising events and building a large number of civil projects is to "employ people" and raise private financial resources for local prosperity, which not only provides disaster relief, but also comforts the people, and immediately produces immediate results.

If in the past, the imperial court was responsible for the people, but now, the imperial court has become a promoter and guide, fully dispatching the local "surplus wealth" to appease the local people.

For him, it opened the door to a new world.

Moreover, Yan Shiyue, who proposed this, really impressed him.

Emperor Ming Yan glanced at the little girl who looked down.

She yelled that she hadn't eaten lunch just now, so she asked Gu Jiuxing to serve a bowl of noodles, and she was sitting by the window eating, like a little squirrel.

Although she used to have a lot of weird talents, they were all biased towards "skills", and it was only at this time that he realized that what she had in her head was indeed worth excavating.

It was at this time that he strengthened his determination to let Yan Shiyue enter the court, and when he looked at her, he even thought about what official position he would let her hold in the future.

Emperor Ming Yan smiled slightly, and said: "The prince goes first, Shilang, you organize people to make this disinfectant powder, Yue'er, you help your fourth brother." ”

Yan Shiyue didn't notice anything wrong at all, and bit her face in response.

Then the prince left first, she finished eating noodles, went out of the palace with the four princes, and immediately organized people to prepare to get disinfectant powder.

The four princes have always done things personally, and she is also the first in important matters, and the two of them quickly organized the manpower, and then rushed to make cyclone separators and other equipment.

The two took a group of craftsmen and worked non-stop for several days, during which they finally began to produce after several failures. It wasn't until it entered the aging stage that it was a relief.

Although the flood is a major event, after all, it is far away, and life in Chang'an City is still as usual.

At dinner, Yan Shidi asked Yan Chengyuan: "Dad, where are Yue'er and the fourth prince now?" ”

Before Yan Chengyuan could answer, Meng Min said, "Yue'er came back at noon today, saying that she came to eat in the evening, why hasn't she come over yet?" While calling someone to urge, he asked him again: "Why did you remember to ask Yue'er?" What do you ask her for? ”
