"Chairman, you are really good at winning people's hearts! I have to say that working with a boss like you makes me exhausted and happy!" There were no outsiders around, so Liu Yunli also joked with Yu Qingyang.
"Haha! Don't! Don't be exhausted! If you are exhausted, who will do the work for me?
There is no property in hell for me!" Yu Qingyang also joked with Liu Yunli.
"Okay! Chairman, what you are saying is that if you have your property in hell, you will not let us go even if we are exhausted!"
When I get to hell, I will still work as a cow and a horse for you!" Liu Yunli smiled sweetly and glanced at Yu Qingyang with her beautiful eyes.
Yu Qingyang felt numb all over from the electricity.
I have to say that Liu Yunli is very beautiful, with a pair of talking eyes, which is very charming.
Fortunately, Yu Qingyang had just fought Tian Tian for 300 rounds last night, and he was still able to hold his own.
At noon, Yu Qingyang had a meal with the executives of Huayu Animation Production Company and the leaders of various project teams.
…
In the afternoon, Yu Qingyang came to the Bailonggang Sewage Treatment Plant Project Design and Research Office.
A project design research group jointly established by Huayu Water Design Institute and more than a dozen domestic universities.
Originally, only a few universities such as Tongji University, Tsinghua University, and Haihe University participated. However, after learning about the project of Huayu Water and the Shanghai Municipal Government to jointly develop Asia's largest sewage treatment plant, domestic universities began to find ways and rely on connections to find ways to participate.
Sewage treatment projects and sludge treatment research groups are not free markets, so naturally not everyone can enter if they want to.
Yu Qingyang picked and picked, and finally chose 985,211, a dozen relatively strong schools.
The office space of the scientific research team is located in a scientific research building of Tongji University.
When Yu Qingyang came, he did not inform them. When he arrived, Gu Wen and others were having a meeting, arguing fiercely about which sludge treatment process to use.
Yu Qingyang did not go in, nor did he ask anyone to inform the experts who were meeting and discussing inside. He just stood at the door and listened to their discussion.
Sludge treatment is the process of reducing, stabilizing and harmlessly treating sludge.
There are also many classifications of sludge, including original sludge, primary sludge, secondary sludge, activated sludge, digested sludge, etc.
If classified according to source, it can also be divided into domestic sewage sludge and industrial sewage sludge.
Among them, industrial sewage sludge can be divided into many types.
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! To say it is a beautiful dream is not an exaggeration!
Nowadays, urban sewage, even domestic sewage, contains a large amount of detergent, shampoo, car cleaning agent and other chemicals. How can such sludge be composted?
If the fertilizer produced using composting technology is used, will the crops grown contain excessive amounts of toxic ingredients?
Who of you dares to eat the crops grown with such fertilizer?" A gray-haired old professor stood on the stage, staring at the eyes like cowbells, and loudly questioned the experts in the conference room.
"Professor Lin, we didn't say that all sludge should be used for composting!
We can..."
An expert in his fifties stood up and wanted to explain his idea, but was interrupted rudely by Professor Lin, "What can be done? Can sewage be classified?"
Stop joking!
This is simply unrealistic!
Our municipal official website cannot be so detailed!
If we want to classify sewage, how much financial and material resources will be invested to transform 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, for the subdivision and renovation of the municipal official website, not to mention our Huayu Water Affairs, even the country cannot afford the cost for the time being!" Gu Wen shook his head honestly.
Transforming the municipal official website is not just about thickening and expanding the capacity, but subdividing the municipal sewage pipes.
Nowadays, washing pots, washing vegetables, taking baths, toilets and toilets all enter the sewage pipes.
The wastewater produced by washing pots and vegetables contains a large amount of chemical agents such as detergents. These chemicals are not noticeable in small amounts, but they are collected by thousands of households and the sediments after sewage treatment are all accumulated in the sludge.
Can you imagine how many chemical components such sludge contains?
"Professor Lin, your burning method is unreliable!
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 and still cannot solve the generation of secondary pollution!" Another expert and professor stood up to oppose the treatment process advocated by Professor Lin.
"First, the energy consumption issue you mentioned, I have mentioned this before. Carbonizing the sludge first and then incineration can greatly reduce air pollution.
Second, incineration will generate heat energy. The heat energy generated by incineration can be used to dry and carbonize the sludge. This is a recycling method!
In addition, I have also proposed before that the ash produced after incineration should be melted!
All we need to do is research on heavy metal solidification treatments!
Find a practical technical process for heavy metal solidification and extraction!
Huayu Water has invested a lot of money and summoned hundreds of scientific researchers from more than a dozen of our universities, isn’t it just to explore a more feasible sludge treatment process?”
Professor Lin has a good level of eloquence and speaks clearly, and he gradually gained the upper hand.
"Bah!" 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 to Gu Wen, then smiled at the experts and professors in the conference room: "Experts and professors, the discussion just now was very exciting!
As a layman, I benefited a lot from listening to it!
It can be seen that during this period, everyone’s hard work was not in vain, and we basically have a clearer understanding of sludge treatment!”
"Chairman, the order is clear, but there are still many problems that need to be solved to truly realize large-scale and large-volume 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 and the use of thermal energy for drying and carbonization conflict with the design principles of sewage treatment plants!
What we want to build is a garden-style sewage treatment plant. Putting several 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 dehydrated before it is dried!
The dewatered sludge can already avoid environmental pollution during transportation!"
“However, transportation costs are another problem!
When a two-million-ton sewage treatment plant is operating at full capacity, the amount of sludge produced in a day is astonishing!"
“Since this expense is unavoidable, we can only accept it!
No science, technology, or production process is perfect!
They are all constantly improved during use! Continuous progress!" Yu Qingyang said with a smile.
