Great Power Project

Chapter 559 Sludge Treatment Process
After arranging the affairs of Huayu (Modu) Real Estate Co., Ltd., Yu Qingyang did not leave Modu.

Instead, stay in the magic capital.

The completion of the personnel adjustment of Huayu (Modu) Real Estate Co., Ltd. does not mean the completion of the restructuring.

Afterwards, Chen Changyi had to lead the people from the finance department to split up the finances of Modu Company.

Financial division is not troublesome, the financial general ledger is originally at the group headquarters.

Now we only need to clarify their respective assets and liabilities, and re-establish the financial relationship with the group company and the financial relationship between Shanghai, Jiangsu, Zhejiang and Anhui.

Yu Qingyang stayed for the construction of Bailonggang Sewage Treatment Plant.

The design of the Bailonggang sewage treatment plant has been in progress for several months, and the first draft is almost due.

With the experience of Qindao City and Quanshui City, the design of Bailonggang Sewage Treatment Plant this time can be regarded as an examination for Huayu Water Design Institute.

"The Devil City government means that the Bailonggang sewage treatment plant will be upgraded on the basis of the old plant!
But after our explanation, the Shanghai Metropolitan Government agreed to our plan, the old factory was demolished, and all new factories were built!

The planned area of ​​the new Bailonggang sewage treatment plant is 120 million square meters! "In the multi-functional hall of Huayu Water Design Institute, Gu Wen gave a lecture.

Let me first introduce the general situation of Bailonggang Sewage Treatment Plant.

"Our preliminary idea is that the Bailonggang sewage treatment plant will be built 20 meters underground!

We plan to build five sets of high-efficiency sedimentation tanks, each with an independent reaction unit, consisting of a mixing zone, a flocculation zone, a push flow reaction zone, a sedimentation zone and a sludge concentration zone.

The single pond is 25.9 m long, 17 m wide, 8.3 m deep, with a volume of 2407 m64 and a residence time of [-] min.

A sloping plate is installed on the upper part of the sedimentation area. The sloping plate area of ​​a single pool is 170 square meters, and the volume of a single pool of a coagulation tank is 140 cubic meters, with a size of 6 m×3.2 m×7.3 m.

Each group of high-efficiency sedimentation tanks can treat 42 cubic meters of sewage per day. "

Teacher Lu and the others are very efficient in their work. In just a few months, they even produced the renderings.

Moreover, their design is very bold, and they actually want to excavate all the land of 120 million square meters.

Built at a depth of 20 meters, this is an ultra-deep foundation pit excavation.

The amount of work is huge!

You know, when he was bragging in the city government, he didn't really plan to build all the buildings underground.

It would be nice to be half underground and half above ground!
The original planned budget is estimated to be insufficient!

I really don't know how expensive firewood, rice, oil and salt are!

Yu Qingyang sat under the stage and thought about it, but he forgot that it was he who said at the beginning that he wanted to see the largest sewage treatment plant in Asia and the largest garden-style sewage treatment plant in the world.

Teacher Lu and Gu Wen have completely realized his ideas.

"The mixing area is equipped with 500 sets of Ф18 mixing mixers, the flocculation area is equipped with 3600 sets of Ф18 flocculation mixers, the concentration area is equipped with 17 sets of Ф18 m thickening mud scrapers, 18 sets of residual sludge pumps are used and 6 are used, and 18 sets of return sludge pumps are used and 6 are used. In addition , set up a dosing system, including coagulant dissolution, dilution, proportioning and dosing, controlled by PLC."

Gu Wen on the stage didn't know Yu Qingyang's thoughts, and was still immersed in the great design, continuing to explain their design.

"The sludge is advanced into the storage tank and then into the dehydration machine room.

The sludge storage tank is divided into 6 grids, each grid is 13m×13m, the water depth is 4.5m, and each grid is equipped with 2 submersible mixers…

The plane size of the sludge dewatering machine room is 13.3 m×27 m, two-story, with 4 centrifuges and 1 backup, with a single machine capacity of 2 kg/h, working 600 hours a day, and 20 sets of dosing equipment.

The centrifugally dewatered sludge has a moisture content of about 65% and is transported to the sludge landfill for disposal.

The blank land in the embankment of the factory area is used as a sludge landfill. The area inside the factory is about 27 hectares, and the area outside the factory is about 16 hectares. The landfill inside the factory and outside the factory are divided into 6 landfill areas respectively. About 5.5 hectares, separated by earth embankments, and one-way lanes are built on the embankments to facilitate the transportation of sludge...

The quality of the tail water treated by the underground sewage treatment plant can reach the first-class A discharge standard!
After the artificial ecological system purification of the artificial wetland system on the ground, it can reach the drinking water standard of Class III!

It is estimated that about [-] cubic meters of tail water of Class III drinking water standard can be produced every day!
Regarding the design of the above-ground constructed wetland system, please invite the professors from Pengcheng Institute of Water Sciences to explain! "After Gu Wen finished speaking, he was about to step down and gave up the podium to Pengcheng Institute of Water Sciences.

"Wait!" Yu Qingyang frowned.

The part about sewage treatment just now is good, but the part about sludge treatment is just a matter of landfilling.

This made Yu Qingyang very dissatisfied!

At present, the domestic sewage treatment process is basically on par with the international level. The only thing that is lacking is the commercial operation of sewage treatment, which has just begun to be piloted.

However, in terms of sludge treatment, it is no longer backward.

It just didn't even start!

"Mr. Gu, the sludge treatment is a bit too simple and rough, and the research on sludge treatment can be put on the agenda!" Yu Qingyang called Gu Wen and said.

"Chairman, now the whole world is dealing with sludge, and the landfill method is basically used..." Gu Wen stood still, and after hearing what Yu Qingyang said about sludge treatment, he opened his mouth to explain.

"I don't care about other countries in the world, I only care about China's sludge treatment!

How much sludge can be buried in the [-] hectares of idle land in Bailonggang?
According to the designed sewage treatment capacity, how long can the landfill area of ​​27 hectares be used? "

Gu Wen pressed the computer for a while, and then said: "According to the designed sewage treatment capacity, it is estimated that by 2020, the landfill area of ​​27 hectares will be filled!"

"2020, that is to say, only 17 years from today!

What to do after 17 years?
Don't think that 2020 is far away from us, time flies, and it will fall in a blink of an eye!
What to do after 17 years?
Then let the city government expropriate land for landfill?

Mr. Gu, people have short-term worries without long-term worries!

So, I say, start to consider the sludge treatment process now! "

"Chairman, the sludge treatment process, the mainstream in the world now is the landfill method..."

"I know that the mainstream of the world is landfill, but the national conditions of each country are different!
Which country has a higher population density than China?
Which country's sewage treatment pressure is greater than China's?
We can't always chase after foreign countries, the processing technology of foreign countries is not necessarily suitable for domestic! "Speaking of this, Yu Qingyang's tone became a little harsh.

He was not angry that Gu Wen did not come up with a reliable sludge treatment process, but was angry that Gu Wen took the United States and Europe as examples in everything.

The practices of foreign countries are all advanced, and the practices of foreign countries are all correct.

Isn't this a kind of xenophiliac?
"Chairman..."

"I'm not asking you to come up with a sludge treatment plan now!

Just telling you guys, be prepared for a rainy day!

From now on, study the process of sludge treatment!
It is necessary to achieve harmless treatment of sludge and recyclable treatment.

If you need funds, I can give you funds. What kind of talents are needed, we can recruit them, or let headhunting companies dig them! "Yu Qingyang directly stopped Gu Wen's words, and said sonorously.

"Chairman, we will definitely study it carefully, and we will definitely live up to the expectations of the chairman!" Gu Wen was blocked by Yu Qingyang from trying to explain, so he could only promise.

"Haha, I look forward to your good news!" Yu Qingyang smiled heartily.

"The current domestic sewage treatment plants are basically heavy water and light mud, and they pay more attention to the treatment of sewage, but the sludge produced by sewage treatment is simply buried.

Some are even dumped directly into rivers, lakes...

Cause secondary pollution to river water and lake water!

It should be noted that sludge that has not undergone harmless treatment itself is a big source of pollution!
Other enterprises or local governments can ignore the sludge, and can pay more attention to water than mud.But we can't!

We are the pioneers and pioneers in the sewage treatment industry!
We must have a sense of responsibility and a sense of mission to shoulder heavy responsibilities! "

Yu Qingyang has not been idle during this time, although he has not come out, staying at home with his son.

But he has never left behind his homework. He has found many books, articles, and reports on water treatment from home and abroad to study and research.

With in-depth research, Yu Qingyang felt more and more that there was too much shortage in the domestic sewage treatment industry.

For example, in the treatment of sludge, foreign countries have begun to reduce the amount of sludge through incineration and treat it in a harmless manner.

The reason why Yu Qingyang did not directly mention this method at the meeting was because he believed that Gu Wen would definitely know about the sludge incineration method, and Yu Qingyang also had doubts about the sludge incineration method.

Does incineration cause air pollution?

The incineration method can treat the sludge in a harmless and reduced amount, but will incineration produce a large amount of harmful gases?
Another one, Yu Qingyang didn't want his words to bind Gu Wen and the others.

Gu Wen and others are elites with broad vision and keen thinking.

You only need to make a request, and you don't need to make any instructions.

For scientific research, you cannot give more instructions. If you give too many instructions, it will only constrain their thinking.

"Papa papa!" There was a burst of applause beside him.

It was Deputy Mayor Sun who listened to the design report with Yu Qingyang.

"What Director Yu said is great! Director Yu's sense of social responsibility and sense of historical mission is admirable!" Deputy Mayor Sun applauded while applauding.

"Mayor Sun, you are too proud! If a company does not have a sense of social responsibility and a sense of historical mission, it will not last long!
Even if it achieves temporary success due to the trend of the times, it will also be abandoned by the trend of the times and quickly close down! "Yu Qingyang said modestly.

Yu Qingyang said those words before, not because Deputy Mayor Sun was here, so Yu Qingyang said those words that sounded very high-sounding.

These are Yu Qingyang's true thoughts.

Next, the explanation of Pengcheng Institute of Water Sciences will be even more exciting.

The design of the artificial wetland system on the ground is jointly designed with Jiangnan Landscape Design Institute.

The entire artificial wetland system is a huge Jiangnan garden.

The design is very beautiful, at least it looks like this in the design renderings.

Pavilions, waterside pavilions, small streams, artificial lakes, and gurgling water on the rockery form artificial waterfalls.

The renderings even depict the koi raised in the lake.

However, because of Yu Qingyang's sudden interruption before, although the subsequent report was wonderful, many people were a little absent-minded.

At least Teacher Lu and Gu Wen were a little absent-minded.

They are all thinking about the question Yu Qingyang raised before.

Teacher Lu couldn't help but sigh in his heart, as a student, he has a really big heart!Foresight is also very high!

While other domestic water treatment companies are still groping forward and exploring carefully, Huayu Water has quickly occupied several important cities.Become the largest sewage treatment company in China.

And it went a step further, turning its attention to the research on sludge treatment technology that other water treatment companies have not yet touched.

At the same time, I feel fortunate that I resolutely accepted Yu Qingyang's invitation.

It was also the invitation of that phone call that changed the trajectory of his entire life.

I personally witnessed the development of the national water treatment industry, and I personally experienced it and participated in the development of the water treatment industry.

"Dong Yu, our Tongji University has done a lot of research on water treatment.

They participated in the design of the previous Bailonggang sewage treatment plant!
You see, did you involve them in your sludge treatment research?The two of you can join forces and try to come up with practical research results as soon as possible..." Deputy Mayor Sun didn't concentrate on listening to the report, but discussed with Yu Qingyang in a low voice.

As the deputy mayor of a municipality directly under the central government and an economic capital, Deputy Mayor Sun still has a vision.

Maybe he didn't pay attention to the problem of sludge treatment before, but after Yu Qingyang raised it, Deputy Mayor Sun keenly realized that the research on sludge treatment is urgent.

Research on sludge treatment is very necessary.

Otherwise, as Yu Qingyang said, a lot of effort and a lot of money was spent to treat the sewage, but the sludge produced by the sewage polluted the water system again.

That was a joke!
As everyone knows, in future generations, this joke in Deputy Mayor Sun's heart will be played out every day and every moment.

The front foot is treated, the rear foot is polluted, and then treated again, and then polluted again, which has formed a cycle.

"Mayor Sun, Huayu Water Design Institute has many talented students from Tongji University! Not only are there talented students from Tongji University, but also Peking University, Tsinghua University, Chinese Academy of Sciences, Fudan University, and Wuhan!
Our company has always attached great importance to the cooperation with universities! "Yu Qingyang laughed softly.

"As for the joint research with Tongji University on the sludge treatment process, we are definitely very willing!
I also hope that Mayor Sun can help to bridge the gap and make this happen! "

　I drank too much yesterday and forgot to update!

　　Make it up today!
