Chapter 636 Debate over Sludge Treatment Process

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

"Haha! Don't! Don't be exhausted! You are exhausted, who will work for me?

I have no inheritance in hell! "Yu Qingyang also joked with Liu Yunli.

"Okay! Chairman, what do you mean, if there is your property in hell, even if we are exhausted, we will not let us go!

When I get to hell, I will treat you like a cow or a horse! "Liu Yunli smiled coquettishly, and gave Yu Qingyang a look with her beautiful eyes.

Yu Qingyang was numb all over.

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

Fortunately, last night Yu Qingyang had just fought Tian Tian for [-] rounds, and he was still able to hold on.

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 Design and Research Office of the Bailonggang Sewage Treatment Plant Project.

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

Originally, only a few universities including Tongji, Tsinghua University and Haihe University participated, but after knowing that Huayu Water and the SH Municipal Government jointly built the project of Asia's largest sewage treatment plant, they all tried their best to participate through connections.

Sewage treatment projects and sludge treatment research groups are not free markets, so naturally not everyone can get in if they want.

Yu Qingyang picked and picked, and finally chose more than a dozen 985, 211 with relatively strong strength.

The office space of the scientific research team is located in a scientific research building of Tongji University.

When Yu Qingyang came, he didn't inform them. When he arrived, Gu Wen and 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 ask anyone to notify the experts who were discussing the meeting inside. He just stood at the door and listened to their discussion.

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

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

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

"Sludge composting is just a beautiful idea! It is not too much to say that it is a beautiful dream!
Nowadays, urban sewage, even domestic sewage, contains a lot of detergent, shampoo, car cleaning agent and other chemicals. How can such sludge be used for composting?

Will the crops grown with the fertilizer produced by composting technology be born with excessive levels of various toxic components?

Who of you would dare to eat the crops grown with such fertilizer? "An old professor with gray hair stood on the stage, staring into cowbell-like eyes, and loudly questioned the experts in the conference room.

"Professor Lin, we didn't say that all the sludge was composted!
We can..."

An expert in his fifties stood up and wanted to explain his idea, but was interrupted by Professor Lin unceremoniously, "What can we do? Can we classify sewage?

Do not make jokes!
It's not practical at all!

Our municipal official website can't be so detailed!
If you want to classify the sewage, how much money and resources will be invested in the renovation of the municipal official website?
Mr. Gu, Hua Yu Water has the ability 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 renovation of the municipal official website, not to mention Huayu Water, even the country can't afford the cost for the time being!" Gu Wen shook his head honestly.

Renovating the municipal official website is not simply bolding and expanding, but subdividing the municipal sewage pipes.

Now, washing pots, washing vegetables, bathing, and toilets all enter the sewage pipes.

Wastewater from washing pots and washing vegetables contains a large amount of chemicals such as cleaning agents. These chemicals are not visible in small quantities, but thousands of households gather together, and the sediments after sewage treatment are all accumulated in the sludge.

It is conceivable how big the chemical components are in such sludge?
"Professor Lin, your method of burning is not reliable!

First, incineration will cause air pollution, and second, incineration requires a lot of energy!

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

"First, the energy consumption problem you mentioned, I have mentioned this before, the sludge is first carbonized and then incinerated, which can greatly reduce air pollution.

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

In addition, I have also proposed before that the marl produced after incineration should be melted!

All we need to do is research on heavy metal curing!
Find out a feasible heavy metal solidification and extraction technology process!
Huayu Water has invested a lot of money and convened hundreds of scientific researchers from more than a dozen of our colleges, isn't it just to explore a more feasible sludge treatment process? "

Professor Lin's level is good, his eloquence is also very good, his speech is clear, and he gradually gained the upper hand.

"Papa papa!" Seeing that the debate inside had almost come to an end, Yu Qingyang clapped his hands and walked in.

"Chairman, you are here!" Seeing Yu Qingyang coming in, Gu Wen rushed forward to say hello.

Yu Qingyang nodded at Gu Wen, then smiled at the experts and professors in the meeting room: "Experts and professors, the discussion just now was very exciting!
As a layman, I have benefited a lot from listening to it!
It can be seen that during this period of time, everyone's hard work has not been in vain. Basically, we have a relatively clear understanding of sludge treatment! "

"Chairman, the order is clear, but there are still many problems to be solved to realize large-scale and large-scale sludge treatment!
First of all, the drying and carbonization of sludge consume a lot of energy!
If electricity is used for drying and carbonization, the power consumption will be astronomical!

Using an incinerator to use thermal energy for drying and carbonization treatment also conflicts with the design principles of the sewage treatment plant!

What we are going to build is a garden-style sewage treatment plant. Putting a few incinerators in the sewage treatment plant will directly affect the overall effect of the garden! "Gu Wen stepped forward to explain the current research progress.

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

I know that sludge will be dewatered before drying!

The dehydrated sludge can already avoid environmental pollution during transportation! "

"However, transportation costs are another problem!
The 200 million-ton sewage treatment plant is operating at full capacity, and the amount of sludge produced in a day is very amazing! "

"Since this fee is unavoidable, we can only accept it!
Any kind of science and technology, any kind of production process, will not be perfect!
They are constantly being improved in use!Keep improving! "Yu Qingyang said with a meaningful smile.
