Mayor Gao said excitedly: "Smart city is not just a set of software that can be achieved. He depends on all of us working together.

It also has to cooperate with a lot of hardware facilities. If it is a city full of garbage, it is impossible to say that it is a smart city.

In Yanjing alone, 20,000 tons of garbage are generated every day. It all depends on the simplest landfill treatment, and the price is 500 yuan per ton

To dispose of them all, it costs 10 million yuan a day. Our whole city range, the whole country. The daily cost of disposing of garbage will be astronomical.

If the land used for landfill is fully developed every year, it can create a lot of value. Not to mention polluting the environment.

We are determined to build a smart city, can we still use this primitive waste disposal method? No, we cannot!

This affects the land we leave to future generations, and we must not do so.

Smart cities also need supporting facilities to ensure their operation.

We have cooperated with many scientific research institutions to finally solve the problem of waste disposal, which is difficult to solve all over the world.

We have built a garbage disposal center outside the city, which can process all the garbage in the city. ”

Mayor Gao made an invitation in the direction of Zhang Zhi, "Here is the core technology inventor of the garbage disposal center."

Professor Yang Bei of the Department of Biology of Huaxia University, and Mr. Zhao Zhiyong, an expert in organic chemistry of Xingyu Technology, please come to the stage. ”

Professor Yang walked up confidently, and Zhao Zhiyong looked a little hesitant.

Zhang Zhi encouraged him and said: "Zhao Zhiyong, go up quickly, this can be on TV, and you will soon become famous."

When you become famous, your parents, your future parents-in-law will be happy for you.

You don't have to worry about anything else, just like you usually do a project review report, you just have an attitude towards those researchers. ”

Zhao Zhiyong got up, he overcame his nervousness and kept cheering himself up.

When Mayor Gao saw them coming up, he happily shook hands with everyone one by one.

On the light curtain on the stage, the resumes of Professor Yang Bei and Zhao Zhiyong are displayed.

Mayor Gao said politely: "Two experts, you can introduce yourself first and briefly introduce your technology.

Educate the people present about the basic scientific principles used in the garbage treatment center. ”

Professor Yang Bei was the first to speak, and he spoke with the temperament of a scholar.

"I am Yang Bei, the former head of the Department of Biology at Huaxia University, and the first person to use life-prolonging medicine.

The journalists who were there probably knew me. After I regained my youth, I put more energy into scientific research.

At that time, I was inspired by Xingyu Technology that the genes of plants can be changed. The genes of other organisms can also change.

I chose to start with bacteria, but viruses were a better choice.

However, the virus mutates too quickly, and host cell culture is required. After careful weighing, I chose the bacterial cells.

The scientific research process is too boring, and everyone doesn't want to listen to it, and there are people who want to know about it. You can go to the virtual space of Huaxia University to find out. ”

From Professor Yang's bland narration, everyone can think of his love for scientific research.

The audience burst into warm applause, all celebrating Professor Yang.

Seeing the performance of the crowd, Professor Yang said calmly: "We have made unremitting efforts to develop a variety of functional bacteria.

There's a group of bacteria, which I've called decomposer bacteria. It can produce a variety of decomposing substances and can dissolve most of the substances.

Some specialize in decomposing organic matter, some decompose metals, and some can decompose cement and stone.

They are cultured specifically to convert most of the material into ionic solutions. ”

After Professor Yang finished speaking, Mayor Gao motioned for Zhao Zhiyong to start speaking.

After listening to Professor Yang's account, Zhao Zhiyong was no longer nervous.

Walking to the front and looking at the people below, he said confidently: "I am the head of the organic chemistry department of Xingyu Technology, my name is Zhao Zhiyong."

I'm not an old professor who uses life-prolonging potions like Professor Yang. I am a real fresh graduate of Huaxia University.

If you want to be like me and want to become a scientist, you are welcome to come to Xingyu Technology. It's going to change your life here. ”

The applause from the audience rang out, and Zhao Zhiyong saw this situation, and he became more confident.

"I developed a material that selectively passes ions through the membrane, 0.5 mm thick material, integrating thousands of different options through the membrane.

At different voltages, it can actively absorb different ions. Trivalent iron, divalent iron, hydroxide, hydrogen ions, etc.

It can actively select the ions needed, one or more ions, through the back of the material, through electrochemical and other methods, recycled and reused. ”

Mayor Gao saw that Professor Yang Bei and Zhao Zhiyong had finished speaking, and he invited them to step down.

Zhao Zhiyong returned to his seat, and he relaxed. Nervous heads are sweating. He thought he wasn't nervous, but he didn't expect that he was still nervous.

Zhang Zhi saw his appearance and said approvingly: "You performed very well. ”

Mayor Gao was at the booth, and he said to everyone solemnly: "Wait a minute, show the garbage disposal center, people with strong mental endurance can use quantum hands to connect the playback device."

He can really experience the effect of the garbage disposal center, and you must adjust the intensity of the bearing and adjust it to the minimum. The main sense is the sense of smell. ”

Hearing his words, someone was curious. Through the quantum phone, connect to the playback device.

Zhang Zhi didn't do that, he knew that the smell of the garbage disposal center must be bad, and this was to find guilt for himself.

Mayor Gao saw that most of the people chose to finish. He began to play the footage of the garbage disposal center.

"This is the real-time picture now, and I'll explain it to you. ”

"The garbage treatment center receives domestic waste, industrial waste and construction waste through pipelines, vehicle transportation and other modes. ”

Garbage disposal centers, sewers, and industrial wastewater pipes are shown in the picture. There are a lot of big trucks.

"The liquid waste is placed in the sedimentation tank and the solid cargo is unloaded into the reaction tank. ”

Everyone saw many large pools, people who didn't use quantum phones were fine, and people who brought quantum phones. There are a lot of people retching, and the smell is too pungent.

Turned to the lowest, the smell is simply indescribable, many times worse than the smell of not cleaning the bathroom for a month.

They can see from the footage that the employees here are working with gas masks.

"Solid waste is put into three types of reaction tanks, which are pre-treated and carefully sorted waste.

If there is no way to sort it, it will be put into the mixing pool, so please be sure to sort the garbage well. Don't waste extra resources.

The bacteria and bait required to be fed into these four types of decomposition tanks were different.

We have different ways to recycle the decomposed objects that are decomposed by bacteria. What is difficult to recycle still needs to be filled up.

Each ion in the sedimentation tank will pass through the membrane through the corresponding ion, and we will compensate by electrons. Recycling. ”

The picture changes, and I see the product after recycling.

Gold bars, platinum bars. Iron ingots, copper ingots. Hydrochloric acid, sodium hydroxide. Most of the common metals and chemical raw materials are found here.

Mayor Gao said excitedly: "We only need 50 yuan to dispose of a ton of garbage. The government also gives subsidies.

It is far less than the cost of them to pull away the smuggling, and we are using economic means. to solve environmental problems.

The water discharged through the garbage disposal center has reached the standard of Class I water and is completely drinkable. ”
