"Chairman, you are really good at buying people's hearts! I have to say, working with a boss like you, I am happy to be tired!" There were no outsiders around, and Liu Yunli also joked with Yu Qingyang.

"Haha! Don't! You can't be tired! You're tired, who's going to work for me?

There's no such thing as my property in hell!" Yu Qingyang also joked with Liu Yunli.

"Yes, Chairman, you mean that if there is your property in hell, we will not let us go even if we are tired to death!

When you go to hell, you will be treated as a cow and a horse!" Liu Yun Lijiao smiled, and glanced at Yu Qingyang with beautiful eyes.

Yu Qingyang, who was electric, was numb.

I have to say that Liu Yunli is very beautiful, with a pair of talking eyes, which is very seductive.

Fortunately, Yu Qingyang just fought with Tian Tian for 300 rounds last night, and he was still able to hold it.

At noon, Yu Qingyang had a meal with the executives of Huayu Animation Production Company and the leaders of each project team.

......

In the afternoon, Yu Qingyang came to the Bailonggang Sewage Treatment Plant Project Design and Research Office.

Huayu Water Design Institute and more than a dozen universities in China jointly established a project design research group.

Originally, only a few universities such as Tongji, Tsinghua University, and Haihe University participated, but after knowing that Huayu Water and the Shanghai Municipal Government were jointly engaged in the project of Asia's largest sewage treatment plant, domestic universities tried their best to participate in the project.

Sewage treatment projects and sludge treatment research groups are not free markets, and naturally not everyone can enter if they want to.

Yu Qingyang picked and picked, and finally chose more than a dozen relatively powerful 985,211.

The research group's office is located in a research building at Tongji University.

When Yu Qingyang came, he didn't inform them, and when he arrived, Gu Wen and the others were in a meeting, and they were arguing fiercely about the sludge treatment process.

Yu Qingyang didn't go in, and he didn't let anyone notify the experts who were holding a meeting and discussing inside, just stood at the door and listened to their discussion.

Sludge treatment is the process of reducing, stabilizing and harmless sludge.

There are also many classifications of sludge, including raw sludge, primary sludge, secondary sludge, activated sludge, digested sludge and so on.

If it is divided according to the source, it can also be divided into domestic sewage sludge and industrial sewage sludge.

Among them, industrial sewage sludge can be divided into many kinds.

Listening to the discussion, Yu Qingyang also realized that sludge treatment is not an independent process, and must be combined with sewage treatment.

"Sludge composting, just a beautiful idea! It's not too much to say that it's a beautiful dream!

Nowadays, urban sewage, even domestic sewage, contains a lot of detergent, shampoo, car cleaner and other chemicals, how can such sludge be used for composting?

Will the fertilizers produced by composting technology grow crops with excessive levels of various toxic components?

Which of you would dare to eat a crop grown with such fertilizer?" a gray-haired old professor, standing on the stage, staring at the cowbell-like eyes, loudly questioned the experts in the conference room.

"Professor Lin, we didn't say that all sludge is composted!

We can ......."

An expert in his fifties stood up and wanted to explain his assumption, but was unceremoniously interrupted by Professor Lin, "What can it be?

No kidding!

It's simply not practical!

Our municipal official website can't be so detailed!

If you want to classify sewage, how much financial resources and materials will be invested to renovate the municipal official website?

Mr. Gu, do you Huayu Water have the strength to complete the subdivision and transformation of the municipal official website?" Professor Lin pointed the finger at Gu Wen again.

"Professor Lin, the subdivision and transformation of the municipal official website, not to mention our Huayu Water, even the state can't afford this cost for the time being!" Gu Wen shook his head honestly.

The transformation of the municipal official website is not a simple expansion of the capacity, but a subdivision of the municipal sewage pipeline.

Now, brushing pots, washing vegetables, bathing, toilets and toilets all go into the sewage pipes.

The wastewater produced by brushing pots and washing vegetables contains a large number of chemical agents such as cleaning agents, which are not visible in small amounts, but are collected by thousands of households and precipitated by sewage treatment, all of which are accumulated in the sludge.

As you can imagine, how big is the chemical composition in such sludge?

"Professor Lin, your burning method is not reliable!

First, incineration causes air pollution, and second, incineration consumes a lot of energy!

Third, the incineration method will cause the accumulation of heavy metals, and it still cannot solve the generation of secondary pollution!" Another expert professor stood up against the treatment process advocated by Professor Lin.

"First, the energy consumption you mentioned, which I have mentioned before, is to carbonize the sludge first, and then incinerate it, which can greatly reduce air pollution.

Second, incineration will produce heat energy, and the heat energy generated by incineration can be used to dry and carbonize the sludge, which is a recycling treatment method!

In addition, I have proposed that the mud produced after incineration be melted!

All we need to do is to do research on the curing of heavy metals!

Find a feasible heavy metal curing and extraction technology process!

Huayu Water has invested a lot of money and convened hundreds of researchers from more than a dozen colleges and universities, isn't it just to explore a more feasible sludge treatment process?"

Professor Lin has a good level, eloquence is also very good, and he speaks clearly, and gradually has the upper hand.

"Bang bang!" Seeing that the argument inside was almost over, Yu Qingyang clapped his hands and walked in.

"Chairman, you're here!" Gu Wen saw Yu Qingyang coming in, and hurriedly stepped forward to say hello.

Yu Qingyang nodded at Gu Wen, and smiled at the experts and professors in the conference room: "Ladies and gentlemen, the discussion just now is very exciting!"

I'm a layman, and I've benefited a lot from listening to it!

It can be seen that during this time, everyone's hard work has not been in vain, and we basically have a clear understanding of sludge treatment!"

"Chairman, the organization is clear, but there are still many problems to be solved to truly achieve large-scale and large-scale sludge treatment!

First of all, the drying and carbonization of sludge consumes a lot of energy!

If electricity is used for drying and carbonization, the amount of electricity required will be astronomical!

The use of incinerators, the use of heat energy for drying, carbonization, and conflict with the design principles of sewage treatment plants!

What we want to build is a garden-style sewage treatment plant, and a few incinerators will be placed in the sewage treatment plant, which will directly affect the overall effect of the garden!" Gu Wen stepped forward to explain the current research progress.

"Is it okay to choose another place to build an incinerator to dry and carbonize the sludge and incinerate it?

I know that the sludge is dewatered before it dries!

After dewatering the sludge, it can already avoid environmental pollution during transportation!"

"However, the cost of transportation is another problem!

The 2 million ton sewage treatment plant is running at full capacity, and the amount of sludge produced in a day is very amazing!"

"Since this cost is unavoidable, then we can only accept it!

Any kind of science and technology, any kind of production process, will not be perfect!

It's all in use, constantly improving!, constantly improving!" Yu Qingyang said with a smile.
