The booming era begins with the director of the Propaganda Department!

Chapter 493 Two-compartment septic tank!
Liu Haizhong and Yan Bugui had no choice but to get up and say goodbye.

As he walked, he was not convinced and kept muttering, "What era is this? Do you still want to follow the rules of parents' orders and matchmaker's words?"

"Ren Weihong must get married, I don't believe you two have any solution!!"

"These Old Liu and Old Yan!! They are really... unreasonable!" Yi Zhonghai collapsed on the stool in anger, cursing hatefully.

I prepared some wine and food and invited these two people over. In the end, these two people ate their own food and drank their own food, which made me very angry.

Where can I go to seek justice for this? !

An auntie came out and started to clear the table. Seeing his red face and thick neck due to anger, she advised him, "You have been neighbors for so many years, don't you know who Lao Liu and Lao Yan are? Just don't take their words to heart."

Although she said this, she also understood her man.

Mr. Yi in their family is a daughter slave. He had a daughter when he was old, and he treated Yi Weihong as the apple of his eye.

Today, Lao Liu and Lao Yan also touched his reverse scale.

"Hey... can I not know them? But, they are talking about our daughter's affairs, how can I not take it to heart?" Yi Zhonghai sighed again. "Is the child asleep?"

"He's asleep, sound asleep..." said the aunt, looking towards the inner room, "It's getting late, you should go take a shower and go to bed too."

"Okay, you don't have to sleep too late. You promised the child that you would take her to the department store to buy new clothes tomorrow..." Yi Zhonghai stood up while giving instructions.

Most of the children in the courtyards cut cloth to make clothes.

But he felt that the clothes he made were not as good as the ones he bought, so every year he went to the department store to buy ready-made clothes for Yi Weihong.

The Chinese New Year is just around the corner, and I must buy new clothes for this year tomorrow.

Yi Weihong kept urging him in the afternoon. Not only that, she also asked him to help Zhang Ximei buy one as well.

"Brother Ximei's pants are too short, can't you buy him a pair too, Dad?" These are the little girl's exact words.

When he thought of this, Yi Zhonghai felt even more disgusted.

Although there is a saying that girls are extroverts, their Wei Hong is too extroverted...

Besides, this girl and Zhang Family's Ninth Brother haven't done anything yet...

Buy a house, you must buy a house! ! It’s best to stay far away from Zhang’s old ninth son, so that they can be like the cowherd and the weaver girl, not seeing each other once a year! !

Even if I risk my life to be the villain who breaks up the couple, I can't let these two be together! !

……

Backyard, Xu family.

After Xu Damao finished pupating the cricket pupae, he stopped Yu Haitang and smoked comfortably.

Yu Haitang looked at him with disgust, and then suddenly thought of something, moved closer, and put her pretty face on his chest;

"Da Mao, the factory is going to build a new house. Should we buy one too?"

"Why buy a house? That's for people who don't have a house. Our house is so spacious..."

Xu Damao lives quite comfortably in the courtyard house and has no plans to buy a house.

Yu Haitang's eyebrows twisted into a knot: "These two rooms are just right for us to live in now, but what about later? Are we not going to have children?"

Xu Damao felt a little guilty. How could he not know his own strength?

Having a child is too far away for him.

He drank the medicinal wine and went to the Union Hospital. Knowing that he would never have the possibility of having children in his lifetime, he had given up.

Now I just want to enjoy life today, have more women, eat more and drink more.

He didn't want to spend a lot of money to buy a house? Or a house that was destined to have no son to inherit?

But he couldn't tell Yu Haitang this. He thought for a moment and said, "It won't be too late to buy it after the baby is born..."

Yu Haitang let go of his arm: "Prepare for a rainy day, understand? Besides, we are both working, and there are so many families with only one worker in the factory who have bought it.

Others go upstairs and downstairs every day, but we, a cadre and a broadcaster, live in this shabby yard, emptying urine pots and using public toilets every morning..."

The more he spoke, the angrier he became. He turned around and pointed his big butt at Xu Damao, ignoring him.

Xu Damao tried to pry her shoulders with a smile, but she refused.

After failing to persuade her for several times, Xu Damao saw that she was really angry, so he gave in.

After all, Yu Haitang is pretty! And she's also a broadcaster, so it's prestigious to take her out. He hasn't had enough fun yet!

Besides, he has been married for the third time. If he divorces Yu Haitang again, it will be disadvantageous for his future promotion! !

Thinking of this, Xu Damao decided to spend money to avoid the disaster.

He came close to Yu Haitang and slid his big hand under the quilt: "Okay, don't be angry. You said you would buy it.

Isn't it just a house? You're talking as if we can't afford it..."

Yu Haitang took advantage of the situation and turned to look at him: "Then you have to buy it in my name."

"Why?" Xu Damao frowned and asked.

"Why do you care about me? We are husband and wife. If you love me, buy it in my name and write my name on it." Yu Haitang pulled her pretty face down again and wanted to turn around again.

Xu Damao quickly grabbed her shoulders and said, "Write, write, write! Whatever you say is what it is! You've got me, little girl, totally taken advantage of by you. You're such a goblin!"

"Don't you just want someone like me?" Yu Haitang chuckled.

Xu Damao was so excited that he wanted to have another go, but he suddenly shuddered...

Well, his face changed, and he turned over with his back to Yu Haitang: "Well, I'm tired. I have things to do at work tomorrow, so I'm going to sleep first."

……

The second day after the Little New Year, the 24th day of the twelfth lunar month.

Grandma Zhang is full of energy because of the return of her eldest grandson.

I got up at six in the morning, cooked a big pot of sticky rice porridge, and steamed a pot of big white steamed buns.

I also fried two dishes early in the morning, one was scrambled eggs with green onions and the other was cabbage stewed with tofu.

When Zhang Shenfei got up, the old lady had already prepared the water for washing his face and had squeezed out the toothbrush.

"Come on, Dafei, wash your face and brush your teeth, and get ready for dinner."

Zhang Shenfei looked at the attentive old lady, and then thought about Tian Xiaozao who was extremely enthusiastic last night, and sighed that it was more than just a short separation that made the heart grow fonder.

After this short separation, even my grandma finds me particularly cute.

After washing up, he sat at the dining table. Tian Xiaozao had already served the porridge to him: "Are you going to the peeler factory later? Or to the municipal party committee?"

"Let's go to the Municipal Party Committee first. I promised Lao Zhao that I would help them renovate the toilets in the old city." Zhang Shenfei took a sip of porridge and felt relieved!
In Hong Kong, I always drink seafood porridge with various ingredients, but in fact, plain porridge tastes better. "Renovate the toilet? This is a big project. Do you have any ideas?" Tian Xiaozao suddenly became interested.

The Jiaodaokou Street she is in charge of is the old city area, and the area within its jurisdiction is full of alleys.

There are many large courtyards and quadrangles in every alley, but almost none of them have toilets in the courtyards.

Most residents can only use the public toilet at the entrance of the alley. There are too many people and too few toilets. Almost every now and then, there are fights over who gets to use the toilet.

Not to mention that dry toilets are difficult to maintain. They are cold in the winter and full of maggots and flies in the summer. These carry viruses and are bad for the hygiene of the area.

So when he heard Zhang Shenfei's words, he was immediately interested and wanted to find out what was going on.

Zhang Shenfei took a steamed bun and ate it, and told her that he had an idea and a rough outline.

But you need to ask a professional to check if this is feasible.

"If professionals say the plan is feasible and can be mass-produced, I will tell you."

"Okay, then I'll wait for your news. By the way, come back early from get off work in the evening. The New Year is almost here, so let's go to the department store and buy some new clothes for the children." Tian Xiaozao didn't have time to make clothes for her children.

In previous years, it was the old lady in their family who did it, but the old lady is old and she doesn’t want to let her work so hard anymore.

Zhang Shenfei nodded and said, "I have to buy it for you too. Although female cadres should be more plain, it would be festive to wear something bright during the New Year, right?"

Tian Xiaozao is the same age as him and is also thirty years old this year.

But she has a baby face, and the years have not left any traces on her face. Instead, they have given her a mature temperament.

In addition, after becoming a cadre, Tian Xiaozao has become more stable and steady. She has lost her former immaturity and recklessness, and instead has the demeanor of a married woman.

Zhang Shenfei thought that at night when the old lady and Zhang Weiguo were not at home, he could take out the QQ underwear he brought back from Gangcheng and let her try it on.

Last night, we were so happy that I forgot about it in a hurry.

After all, they are an old couple and grew up together as childhood sweethearts.

Tian Xiaozao could tell at a glance that this guy had bad intentions.

With the old lady present, she couldn't say anything. She just secretly glanced at Zhang Shenfei and then buried her head in drinking her porridge.

"Little eyes, wait and see how I deal with you tonight!" Zhang Shenfei did not suffer any loss and also gouged it back.

You dare to glare at me? Isn't it time to call at night?

It seems that my Erlang Shen whip still can't teach you how to behave! !
After the family had dinner together, Grandma Zhang took Zhang Weiguo out for a walk.

Zhang Shenfei rode a bicycle and took Tian Xiaozao to work. He first sent Tian Xiaozao to the street office, and then walked towards the municipal party committee.

When I arrived at the place, I first strolled around the collective housing office, showed my face and reported in, then staggered to the urban construction department.

As soon as he entered the door, he was caught by Lao Zhao, the boss of their department: "Comrade Zhang Shenfei, you finally showed up?
What? Just because I asked you to find a solution, you went to hide in Guangdong Province? And you hid there for half a year?
I thought you were going to spend the New Year there and not come back!"

During this period, because Zhang Shenfei had not shown up, the old house toilet renovation project had to be shelved.

Old Zhao was so anxious that he scratched his head every day and ran to the collective housing whenever he had time, but he never saw Zhang Shenfei.

When she saw him appear, she was afraid that he would run away, so she pulled him directly to her office.

"I don't care. Now that you're back, you have to solve the problem for me! If you don't, I'll go to your house during the Chinese New Year."

The dark-faced man even acted like a spoiled brat. Zhang Shenfei felt helpless and teased him, "I don't have any extra beds at home."

"Then I'll sleep on the floor! If that doesn't work, I'll sleep under your eaves. Anyway, you have to come up with a plan for me!!" Lao Zhao started to act like a rogue.

"You don't know, during this time when you were away, I missed you more than your wife did."

"You don't mean to miss me, you just want me to do hard labor." Zhang Shenfei snorted and laughed, "Okay, I won't waste my words with you. I have already thought of a plan. Find the person in charge of this area in your department and let's have a meeting together."

After he finished speaking, he took a clean teacup and went to Lao Zhao's desk to look for tea leaves.

Is there a solution? Hiss! Old Zhao was happy. He didn’t care that he had turned out everything in his desk. He turned around and went out to call for help.

In a small conference room.

Zhang Shenfei took out from his pocket the picture he had drawn when he was bored in Gangcheng, spread it out and placed it on the table.

"This is a two-compartment septic tank I designed. The principle is that the solidified matter decomposes at the bottom of the tank, and the hydrated matter on the upper layer flows into the pipe, preventing the pipe from being blocked and giving the solidified matter (feces and other garbage) sufficient time to hydrolyze.

In simple terms, the tank is divided into three parts: the primary anaerobic chamber, the secondary anaerobic chamber and the clarification chamber. The bottoms of the primary and secondary anaerobic chambers are connected.

After sewage and feces enter from here, they enter the primary anaerobic chamber, and then..."

Zhang Shenfei pointed at the drawings and explained them to everyone bit by bit.

When everyone heard this, they were overjoyed.

Although housing is tight in Beijing now, there is still space to build a toilet in every yard.

The reason why it is not built is simply because dry toilets have a strong smell and are full of mosquitoes and maggots.

If there are such plastic barrels buried underground, the waste produced by everyone can go directly into the barrels. I believe that many courtyards will agree to build toilets.

With a separate toilet in each yard, the flow of people using the toilets at the entrance of the alley can be greatly alleviated, and people don't have to queue up in long queues every morning.

The most important thing is that after the feces are put into the bucket, there is no living space for maggots and flies, and hygiene can be greatly improved.

Clean and hygienic, no more queuing for toilet use, isn’t this the ultimate goal of renovating old toilets?
Old Zhao slapped his thigh excitedly: "I told you, Zhang Shenfei is the best!!!"

"Director Zhang is indeed extraordinary. I heard that you graduated from the Chinese Department? But the design of this two-chamber septic tank uses a lot of knowledge in biology, snow melting, and physics... You are a versatile person!!" The white-faced technician praised with a smile, "If you were not a factory director, I would really like to recommend you to our department."

He was in charge of the biological field of urban construction. The look he gave Zhang Shenfei was even more passionate than the look he gave his newly-married wife.

A technician wearing black-framed glasses pushed the legs of his glasses and suddenly asked a question: "So, most of the substances in this plastic barrel can be degraded, and the gas evaporates from here...

So, the chances of having to scavenge manure are greatly reduced, right? "

Zhang Shenfei nodded. "That's right. Theoretically, if a family of five follows this septic tank, they only need to empty the manure once every three years or so."

“However, nowadays, farmland in rural areas needs to be irrigated with farmyard manure. In this case, there is no way to send manure to rural areas to be used as fertilizer…” said the technician.

He himself came from the countryside and knew the importance of manure to the fields.

Now the streets of the city have cooperated with the rural areas, and the excrement collected by the excrement collectors is taken away by the farmers. Of course, it is not given for free, the commune will give money.

Zhang Shenfei nodded: "You can't have your cake and eat it too. If you want to make money from selling manure, you can't use this, and if you use this, you can't make money from selling manure. It depends on how the street makes the choice."

Another technician also spoke up: "Director Zhang, does this barrel have to be a rubber barrel? Although our country now has Daqing, oil is a precious thing..."

Since the establishment of Daqing, the country has successively built several oil bases. Theoretically speaking, the country can be completely self-sufficient in oil.

But he felt that if the project was to use precious oil to make toilet plastic buckets, it would most likely be rejected...
