Datang broom star

It feels like Jia Pingan is going to bury someone!

……

It's the last day of this month... the monthly pass will be invalid if you don't sell it, Jazz asks for a ticket.

Chapter 308 Li Zhi helps each other, the leader is second

Hygiene has always been a big issue closely related to health.

People in Datang also pay more attention to hygiene. For example, Qingming Canal is river water, but people in Chang'an only use it for cleaning and sweeping.And drinking is well water.

Well water is safer and healthier than river water. This is the simplest concept.

"Those stagnant and rotten things gradually polluted the canal water, and the canal water soaked from the ground... Here I want to talk about the source of well water. There are two sources of well water. One is diving. What is diving? It is the nearest The water source is soaked, the well here is like this, its water source comes from the water source soaked in the Qingming Canal..."

Yuchi, it's uncomfortable not to interrupt, Xun Yu suddenly realized, "Sir, those rotten water soaked into the well, and then people who drink this water will get sick."

Jia Ping'an had always wanted to deal with his problem, and Li Yuanying responded most positively, slapping him away.

"This king will teach you on behalf of my husband."

Li Yuanying said it with confidence, and when he saw Yuchi Xunyu's hideous face, he couldn't help but feel a little regretful.

This silly black boy wouldn't be cruel to the king secretly.

Jia Pingan nodded, looked at how embarrassing a certain student was, but secretly hated him, and was about to turn around and deal with this guy.

"It's so? But... how to prove it?" Some officials questioned.

Today, when Jia Ping'an said that he wanted to solve the root cause of the people's easy illness in this area, Li Zhicai sent someone here.But when Jia Ping'an spoke, it was something they didn't understand, and he was confused.

"If the water in the well comes from a ditch, why does it taste different?"

Some of Chang'an's wells are bitter and some are sweet.

"Because the places where the water passes are different!"

A group of idiots, Jia Ping'an just fooled around.

The key is……

"Duke Qin is invited."

Qin Ping is here.

"Excuse me, Mr. Qin, how do you drink the water from the well in the past?"

"Sweet." Qin Ping said: "When I was young, and I was greedy for cold in summer, I would drink the well water directly. The sweetness is still unforgettable for me. But then it gradually changed, and the taste was weird. In recent years, it has become more and more delicious. It's not good to drink."

"Those rotten things gradually soaked in." Jia Pingan knew that what he had heard was false, "There are two ways. One, don't drink raw water, this is the iron law. Second, disinfect!"

"disinfect?"

Jia Pingan nodded, "Everyone, please take a look."

"Lime!"

The water in the well was emptied, and lime was thrown down from the top. Someone looked at it, but Li Yuanying, who was throwing lime, made a big move and even lifted the lime.

"Someone's eyes!"

The official covered his eyes and screamed.

"Get water! Here's water!"

Wang Zhongliang asked someone to help him to wash his eyes with the well water dug earlier.

"If you want to make him blind, just wash him with water." Jia Pingan looked indifferent.

"What do you mean?" Wang Zhongliang turned around and looked at him.

"Quicklime is highly corrosive, and it will react strongly when it meets water, burning..."

This group of pampered guys have never touched quicklime at all.

Jia Pingan got a handful of quicklime and sprinkled it in a bowl of water.

laugh!

Got mad.

Wang Zhongliang went limp all over, "Then what?"

"Here's the oil."

Isn't it fragrant with vegetable oil?

After washing the eyes with vegetable oil a few times, the official screamed: "A certain person must be blind, blind!"

"I can't be blind." Jia Pingan looked at his eyes, but they were corroded, but it was not serious, and it would be fine after a while.

"Go home and raise them."

Someone helped the official back, Wang Zhongliang asked, "Why?"

"I said..." Jia Pingan wanted to say that you didn't understand, but he still explained, "Quicklime will react when it meets water, releasing a lot of heat..."

The bowl of water was a little hot.

"Then why can it be disinfected?" Wang Zhongliang felt that this was unclear.

Jia Pingan deeply misses those years of study, "Because many germs have a substance called protein, quicklime can not only generate heat when it meets water, but also generate strong alkali... Heat cannot sterilize, but strong alkali can make the protein of those germs lose active, thereby completing the disinfection."

Everyone was dumbfounded.

Jia Pingan smiled wryly and said, "It's not that a certain person doesn't want to explain, but it's that he can't finish explaining for three days and three nights."

"A certain person is willing to listen for three days and three nights." An official seemed very interested.

"But you have to learn from scratch."

"Yes, I am eager to learn."

"It's a new learning." Jia Pingan said with a smile, "You have to learn it from scratch...that is a whole set of knowledge system, are you sure you are ready?"

"system?"

This is an unfamiliar word.
