Chapter five hundred and seventy-six sludge treatment process
After making arrangements for Huayu (Modu) Real Estate Co., Ltd., Yu Qingyang did not leave Modu.
But stay in the magic city.
The completion of the personnel adjustment of Huayu (Modu) Real Estate Co., Ltd. does not mean the completion of the restructuring.
Later, Chen Changyi also led the people from the finance department to divide the finances of Modu Company.
Financial division is not troublesome, as the financial general ledger is originally located 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 as well as the financial relationship between Shanghai, 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 now the first draft is almost ready.
With the experience of Qindao City and Quanshui City, this design of Bailonggang Sewage Treatment Plant can be regarded as a test for Huayu Water Design Institute.
“The Modu government means that the Bailonggang sewage treatment plant will be upgraded on the basis of the old plant!
But later, after our explanation, the Modu City 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 1.2 million square meters!" Gu Wen gave a lecture in the multi-functional hall of Huayu Water Design Institute.
Let’s first introduce the overview of Bailonggang Sewage Treatment Plant.
“Our initial idea is that the entire Bailonggang sewage treatment plant will be built 20 meters underground!
We plan to build five groups of high-efficiency sedimentation tanks, each with an independent reaction unit, consisting of a mixing zone, a flocculation zone, a plug-flow reaction zone, a sedimentation zone and a sludge concentration zone.
The single pool is 25.9 m long, 17 m wide, 8.3 m deep, 2407 cubic meters in volume, and 64 min in residence time.
An inclined plate is set up in the upper part of the sedimentation area. The area of the inclined plate of a single tank is 170 square meters. The volume of a single pool of the coagulation tank is 140 cubic meters, and the size is 6 m×3.2 m×7.3 m.
Each set of high-efficiency sedimentation tanks can process 420,000 cubic meters of sewage per day."
Teacher Lu and his colleagues are very efficient in their work. In just a few months, they even produced renderings.
Moreover, their design was very bold, and they actually had to excavate the entire 1.2 million square meters of land.
Built twenty meters underground, this is an ultra-deep foundation pit excavation.
The amount of this project is huge!
You know, when he was bragging to the city government, he was not really planning to build everything underground.
It would be great to be able to do half underground and half above ground!
The originally planned budget is probably not enough!
You really don’t know how expensive firewood, rice, oil and salt are!
Yu Qingyang sat in the audience and muttered, but he had forgotten that at the beginning, he said 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 completely realized his ideas.
"The mixing area is equipped with 18 sets of Ф500 mixing mixers, the flocculation area is equipped with 18 sets of Ф3600 flocculation mixers, the concentration area is equipped with 18 sets of Ф17 m thickening sludge scrapers, 18 sets of residual sludge pumps are used and 6 are in standby, and 18 sets of return sludge pumps are in use and 6 are in standby. In addition,
, set up a dosing system, including coagulant decomposition, dilution, proportioning and dosing, controlled by PLC."
Gu Wen on the stage didn't know Yu Qingyang's thoughts. He was still immersed in the great design and continued to explain their design.
“The sludge is first stored in the storage tank and then enters the dewatering machine room.
The sludge storage tank is divided into 6 compartments, each compartment is 13 m × 13 m, and the water depth is 4.5 m. Each compartment is equipped with 2 submersible mixers...
The plane size of the sludge dewatering machine room is 13.3 m × 27 m, two-story, equipped with 4 centrifugal dehydrators and 1 standby, with a single machine capacity of 2 600 kg/h, working 20 hours a day, and 3 sets of dosing equipment.
After centrifugation and dewatering, the sludge has a moisture content of approximately 65% and is transported to a sludge landfill for disposal.
The empty land within the factory dike is used as a sludge landfill, with an area of about 27 hectares inside the factory and about 16 hectares outside the factory. The landfills inside and outside the factory are each divided into 6 landfill areas, with the largest landfill area
About 5.5 hectares, separated by earth embankments, with a single lane built on the embankment to facilitate the transportation of sludge...
The quality of the tail water after being treated by the underground sewage treatment plant can reach Class A discharge standards!
Then, through the artificial ecosystem purification of the above-ground artificial wetland system, it can reach Class III drinking water standards!
It is expected to produce about 4,500 cubic meters of tail water with Class III drinking water standards every day!
Regarding the design of the above-ground artificial wetland system, please ask the professor from the Pengcheng Institute of Water Sciences to explain it!" After Gu Wen finished speaking, he was about to step down and gave up the podium to the Pengcheng Institute of Water Sciences.
"Wait!" Yu Qingyang frowned.
The part about sewage treatment I just talked about is good, but the part about sludge treatment is just a matter of landfill.
This made Yu Qingyang very dissatisfied!
At present, domestic sewage treatment technology is basically on par with international standards. The only thing lacking is the commercial operation of sewage treatment, which has just begun to be piloted.
However, when it comes to sludge treatment, it can no longer be described as lagging behind.
It just didn’t even get started!
"Mr. Gu, sludge treatment is a bit too simple and crude. Research on sludge treatment can be put on the agenda!" Yu Qingyang stopped Gu Wen and said.
"Chairman, when it comes to sludge treatment all over the world, the burial method is basically used..." Gu Wen stopped and listened to Yu Qingyang's talk about sludge treatment and explained.
“I don’t care what other countries in the world do, I only care about China’s sludge treatment!
How much sludge can be buried in twenty hectares of idle land in Bailonggang?
According to the designed sewage treatment capacity, how long can a 27-hectare landfill area be used?"
Gu Wen held the computer and pressed it for a while before he said: "According to the designed sewage treatment capacity, it is expected that the twenty-seven hectares of landfill area will be filled by 2020!"
"2020, that is to say, there are only seventeen years from today!
What to do after seventeen years?
Don’t think that 2020 is far away from us. Time flies by and it will fall in the blink of an eye!
What to do after seventeen years?
Are you going to ask the city government to acquire land for landfill?
Mr. Gu, if you don’t have long-term worries, you will have immediate worries!
So, I say, we must start thinking about the sludge treatment process now!”
"Chairman, the mainstream sludge treatment technology in the world is landfill..."
“I know that the mainstream method in the world is landfill, but the national conditions of each country are different!
Which country has a greater population density than China?
Which country has greater sewage treatment pressure than China?
We can't always chase after foreign countries. Foreign treatment techniques may not be suitable for China!" 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 technology, but he was angry that Gu Wen took the United States and Europe as examples in everything.
All foreign practices are advanced and all foreign practices are correct.
Isn’t this a kind of admiration for foreigners?
"Chairman..."
“I’m not asking you to come up with a sludge treatment plan now!
Just telling you, be prepared for a rainy day!
Start studying the sludge treatment process from now on!
The sludge must be treated harmlessly and recycled.
If you need funds, I can give you funds. We can recruit what kind of talents you need, or let a headhunting company do it!" Yu Qingyang directly stopped Gu Wen's words and said sonorously.
"Chairman, we will study it carefully and we will definitely live up to Chairman's expectations!" Gu Wen was blocked by Yu Qingyang from what he wanted to explain, so he could only promise.
"Haha, I look forward to your good news!" Yu Qingyang said with a hearty smile.
“Currently domestic sewage treatment plants are basically heavy on water and light on mud, and they pay relatively attention to the treatment of sewage. However, the sludge produced by sewage treatment is simply and roughly buried.
Some even dumped directly into rivers and 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 companies or local governments can ignore the sludge coming out, and they can focus on water and despise mud. But we can't!
We are the pioneers and pioneers in the sewage treatment industry!
We must have the sense of responsibility and mission to shoulder heavy responsibilities!”
Yu Qingyang was not idle during this period. Although he never came out, he stayed at home with his son.
However, he never fell behind on his homework. He found many books, articles, and reports on water treatment from home and abroad to study and study.
With in-depth research, Yu Qingyang felt more and more that there was too much lacking 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 harmlessly.
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 at the same time, Yu Qingyang also had doubts about the sludge incineration method.
Will incineration cause air pollution?
The incineration method can detoxify and reduce the amount of sludge, but will incineration produce a large amount of harmful gases?
Furthermore, Yu Qingyang did not want his words to constrain Gu Wen and the others.
Gu Wen and others are visionary elites with broad horizons and agile thinking.
You only need to make requests and don't need to give any instructions.
In scientific research, one cannot give too many instructions. Too many instructions will only constrain their thinking.
"Bah, bang, bang!" There was a burst of applause from the side.
It was Vice Mayor Sun who was listening to the design report with Yu Qingyang.
"What Director Yu said is great! Director Yu's sense of social responsibility and historical mission is admirable!" Vice Mayor Sun praised while applauding.
"Mayor Sun, you are so grateful! If an enterprise loses its sense of social responsibility and its sense of historical mission, it will not survive in the long run!
Even if it achieves temporary success due to the trend of the times, it will be abandoned by the trend of the times and quickly go bankrupt!" Yu Qingyang said modestly.
It was not because Vice Mayor Sun was here that Yu Qingyang said those high-sounding words before.
These are Yu Qingyang's true thoughts.
Next, the explanation from Pengcheng Water Research Institute was even more exciting.
The design of the above-ground artificial wetland system was jointly designed with Jiangnan Landscape Design Institute.
The entire artificial wetland system is a huge Jiangnan garden.
The design is very beautiful, at least that's what it looks like when you look at the design renderings.
Pavilions, water pavilions, small streams, artificial lakes, and artificial waterfalls are formed by gurgling water on rockeries.
The renderings even depict the koi carp raised in the lake.
However, because of Yu Qingyang's sudden interruption, although the subsequent report was exciting, many people were a little distracted.
At least Teacher Lu and Gu Wen were a little distracted.
They were all thinking about the questions Yu Qingyang raised before.
Teacher Lu couldn’t help but sigh inwardly. He, as a student, has such a big heart! He also has a very forward-looking vision!
While other domestic water treatment companies are still groping forward and cautiously testing the waters, Huayu Water has quickly occupied several important cities and become the largest sewage treatment company in the country.
And further, it turned its attention to the research on sludge treatment technology that other water treatment companies have not yet touched.
At the same time, I feel lucky that I resolutely accepted Yu Qingyang’s invitation.
It was that phone invitation that changed his entire life trajectory.
I have personally witnessed the development of the national water treatment industry and participated in the development of the water treatment industry through personal experience.
"Director 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!
Look, do you want them to participate in your sludge treatment research? You two can join forces and strive to produce practical research results as soon as possible..." Vice Mayor Sun did not listen to the report attentively;
Discussing with Yu Qingyang in a low voice.
As the deputy mayor of a municipality directly under the Central Government and an economic capital, Vice Mayor Sun still has a good vision.
Perhaps I had not paid attention to the issue of sludge treatment before, but after Yu Qingyang raised it, Vice Mayor Sun became acutely aware that research on sludge treatment was urgent.
Research on sludge treatment is very necessary.
Otherwise, as Yu Qingyang said, after spending a lot of effort and money to treat the sewage, the sludge produced by the recycled sewage will pollute the water system again.
That really became a joke!
As everyone knows, in later generations, this joke in Deputy Mayor Sun's heart will be played out every moment every day.
Treatment on the front foot, pollution on the back foot, then treatment again, pollution again, has formed a cycle.
"Mayor Sun, our Huayu Water Design Institute has many top students from Tongji University! Not only top students from Tongji University, but also top students from Peking University, Tsinghua, Chinese Academy of Sciences, Fudan, and Wuhan!
Our company has always attached great importance to cooperation with universities!" Yu Qingyang laughed softly.
“As for joint research with Tongji University on the sludge treatment technology project, we are definitely very willing!
I also hope that Mayor Sun can help bridge the gap and facilitate this matter!"
While Yu Qingyang said that his company has many top students from Tongji University and Tsinghua University, he also asked Vice Mayor Sun to help with matchmaking.
It may seem like he is talking a lot of nonsense, but in fact, Yu Qingyang’s nonsense has reversed the relationship between supply and demand.
The suggestions and instructions from the deputy mayor in charge of science, education and health turned into a favor given by Yu Qingyang to Vice Mayor Sun.
What Yu Qingyang said was to tell Vice Mayor Sun that our Huayu Water Design Institute does not lack scientific research capabilities and has always been in contact with these universities.
However, now I give you the piece of cake of promoting school-enterprise joint scientific research, let you take it to increase your resume and political achievements.
