When the motorcade entered the gate, Guo Ming, Hua Ling, and Zhong Yue were standing next to Chen Guang. Lu Fei was looking around the pond and clicking her tongue from time to time.
The medicine was put in last night, and the reaction was almost complete by now.
Before the sun rose, Hua Ling and Zhong Yue tested the main indicators such as CODcr, total phosphorus, and ammonia nitrogen. The concentration of soluble pollutants in these water bodies had dropped to a level that met the requirements.
In addition, during the whole process of adding the drug, the amount of drug in each section was accurate to the gram.
In the end, the test results of the various sections were perfect. Basically, they were very close to the original design parameters. Of course, this was the ideal conditions that disregarded the super difficult to deal with components, and the biggest technical difficulty of classification and pretreatment.
For example, the chemical oxygen demand in the anaerobic pond, which was the concentration of CODcr, was 6000 mg/L. After the drug was added to the second anaerobic pond, the concentration of the effluent directly dropped to 1500 mg/L. The COD removal rate of the UASB anaerobic process reached 75%, which was just reasonable.
The subsequent two-stage aerobic process was also strictly according to this ratio, and finally, the effluent concentration was controlled at around 400 mg/L, and the removal rate of the two-stage aerobic process was maintained at around 50%.
The large capacity of the effluent stabilization pond was also put in drugs to ensure that the COD concentration in the entire pond was around 400 mg/L, and it was seamlessly connected with the effluent of the previous process.
In the entire wastewater treatment plant, each function group was strictly advancing according to this pollutant removal rate ladder. Even if it was a fraud, it was still a very high-end fraud.
Without very professional calculations and accurate tests, it couldn't even be faked.
With the technical ability of the previous staff of the Tongshan Plant, it was impossible.
Fortunately, there were two top students from Gokyo University, Hua Ling and Zhong Yue. The two of them followed Zhuo Jingsi to conduct photocatalysis related research in the school's laboratory. In the past, the two of them had to do precise research to at least four decimal places.
With Professor Shu escorting them, the equipment they brought here was almost all good goods directly from the national photocatalyst laboratory of Gokyo University. Even the pipette guns they used were imported. They were many times better than ordinary local laboratories. They were even better than the ones brought by the central review team.
It was because of Hua Ling and Zhong Yue's continuous and precise tests that they were able to understand the situation of the pollutants in the major functional groups like the back of their hands. Similarly, Hua Ling and Zhong Yue had also put in a lot of effort in the calculation of the dosage. This was also a very meticulous and complicated work.
Chen Guang could do it himself, but he was lazy. He was also very bad at doing experiments. No matter how much of a genius he was, he couldn't know everything that he hadn't learned.
Of course, Guo Ming couldn't relax at all, and Hua Ling and Zhong Yue were also full of melancholy.
The reason was very simple. Although the soluble pollutants could meet the standard, the floating mud floating on the water surface like a floating island was too eye-catching.
This was especially so during the two-stage aerobic treatment process. As the aerator below continued to aerate, the bubbles in the pool rose up along with the mud. It looked like moldy congee with century eggs and lean meat that was boiling.
Although it was not uncommon to force the standard by using drugs to meet the standard in China, it couldn't be a pool full of floating mud, right?
With this kind of operation, there was no need to test it. They could just take a picture and post it on the Internet on the spot. It would be dead in minutes.
It was said that one was deceiving oneself while stealing a bell, but one couldn't poke the eyes of others.
Guo Ming looked at Chen Guang awkwardly, then looked back at the pool in front of him. "Sigh, there's too much mud. It's impossible to fish it all out. There's too much mud in the entire factory."
Hua Ling wanted to laugh, but she couldn't. She patted on Chen Guang's shoulder and continued, "Look, I told you yesterday that it's useless to add medicine, and you insisted on me calculating it. You've really tired me and Zhong Yue."
Zhong Yue also frowned. "In the past, Hua Ling and I also represented the school to help the provincial department do a similar investigation. When the time comes, they will definitely take photos and video evidence, then use a large number of tubes to take samples of the mud and water in the pool. It won't pass."
Guo Ming said again, "That's right. When the time comes, we might be criticized by the whole country again. Although Tongshan Factory has been criticized at least 20 to 30 times, Boss Xia used to be the scapegoat. Now it's you, Chen Guang."
Lu Fei ran down the stairs with her hands clasped. Unlike the others who were sighing, she looked at Chen Guang excitedly and urged, "Hurry up, hurry up!"
Chen Guang, who had been sitting on the chair with his eyes closed, finally opened his eyes. He stood up and smiled at Guo Ming and the others. "Don't panic. Everyone, don't panic."
"How can we not panic? They will be here in a minute! "
Guo Ming was so anxious that he jumped up and down.
Hua Ling and Zhong Yue were confused by his inexplicable calmness. They felt that something was wrong. They looked at Lu Fei, who was eager to try, and they were even more confused.
Hua Ling quietly moved next to Lu Fei. "Sister Fei, does Chen Guang still have some trump card?"
Zhong Yue also pricked up her ears. She wanted to hear a legend.
Lu Fei laughed. "I can't say, but I can promise you that you will soon witness a miracle."
At this moment, an employee ran over from afar. "Chief Chen! Manager Guo! They are here! The inspection team's convoy has entered our factory! "
Guo Ming was shocked. His dark skin instantly turned pale. "This … we're doomed!"
Chen Guang suddenly waved his hand. "Hey, everyone, get ready! It's time to witness a miracle! "
At the same time, Guo Ming wanted to go to the entrance to receive Chen Guang. At the same time, he wanted to know what Chen Guang was trying to do. If Chen Guang wasn't the boss, he would've slapped him in the face by now.
While Guo Ming was still in a daze, Lu Fei had already run to the anaerobic pool and clapped her hands excitedly. "It's going down! It's going down! Awesome! "
"What?"
Hua Ling was still standing next to Chen Guang. She asked from afar.
Lu Fei waved her hand. "You will understand when you see it."
Chen Guang stood there with a smile. He looked like an expert.
Seeing that Chen Guang wasn't going to explain himself, Guo Ming immediately ran towards the anaerobic pool. Hua Ling and Zhong Yue also glared at Chen Guang before they ran towards Lu Fei.
When the three of them finally reached the pool, they realized something was wrong.
The sludge floating on the surface of the Anaerobic Pool, which looked like a bird's eye view of the Thousand-island Lake, was long gone.
"There is another piece! It's sinking! "
Zhong Yue pointed to the corner of the square pool.
"What … what's going on?!"
Guo Ming had been working at Tongshan Factory for half a year, but he had never seen anything like this. There was no special reason for the floating mud to sink!
Hua Ling shook her head. "I don't know."
Lu Fei shouted at the side of the anaerobic pool. She turned around and waved at everyone. "Come over here. We can still see something!"
The three of them ran towards the oxygenation pool again, just in time to catch up with the last batch of sludge that was sinking. The sludge that was bubbling up like boiling porridge had now all gathered together and turned into blocks of rock that were sinking at an extremely fast speed.
The people standing by the pool could even hear the thumping sounds coming from the bottom of the pool. It sounded like someone was throwing bricks into it.
After a few seconds, the anaerobic pool, which had been boiling due to the aeration, gradually became much brighter.
The few of them continued to look down the section. The water in the sedimentation pool was also brightly lit, and the stabilizing pond at the end was as green and translucent as a river.
The mud was all gone!
Guo Ming didn't understand what was happening. It was completely different from the popular science education he had been exposed to.
But he didn't have time to ask Chen Guang for an answer. He quickly excused himself and went straight to the office building.
Hua Ling and Zhong Yue returned to Chen Guang's side.
"Why is this happening? The mud inexplicably congealed together and sank down like bricks! "
Hua Ling waved her hands and said.
Zhong Yue also stared at Chen Guang with wide eyes.
Chen Guang crossed his legs and sat back on the swivel chair. "You don't understand. This is God's will."
"God's will?"
Hua Ling and Zhong Yue were both confused.
Chen Guang nodded heavily. "Yes, this is God's will. It's God's guidance. In fact, I've already expected this. According to my precise calculations, after eight hours of reaction, the drug we put in will produce a chelate structure that you can't understand with your knowledge. I've calculated with my fingers, and now it's time for these flocculation structures to be fully unleashed. "
"So?"
Hua Ling felt that he was talking nonsense.
Chen Guang grinned again. "It's like a spring. You keep stretching the spring, and when you loosen your hand, it will retract with a hum. When the Van der Waals force between the molecules, the molecular chain force, or any other kind of stress exceeds the limit, it will be instantly released. This will cause the originally scattered mud to be instantly absorbed, forming an insoluble precipitate, and then hardening at the bottom of the pool. "
"It's fake!"
Zhong Yue still didn't believe it.
Chen Guang spread his hands. "Is your guess more real, or is it the truth with your own eyes?"
Hua Ling asked, "Then how do you know this will happen?"
"Have you forgotten who I am?"
"Who?"
"I'm an almighty superman! You don't know the terrifying computing power in my brain. It's also because I don't want to compete for the Nobel Prize. Otherwise, it will be me every year, and the Nobel Prize will be renamed to Chen Guang Prize. Anyway, everything is under my control. Okay, you guys go rest and wait for my good news. "
Chen Guang closed his eyes again. He had an expression that said 'summer insects can't talk about ice'.
This time, Hua Ling and Zhong Yue had to believe it even if they didn't want to. Although it was unbelievable, as Chen Guang said, seeing is believing.
In the wonderful world of chemistry, this was actually not impossible. For example, adding the right amount of sodium hydroxide to the copper sulfate solution could instantly form a flocculent precipitate, and the indigo solution would instantly become colorless.
The two girls, whose minds were full of question marks, used this phenomenon to convince themselves as they returned to the factory dormitory.
Perhaps the reaction process in the sewage pool was particularly complicated and had exceeded their understanding, but Chen Guang's explanation was always correct.
"You can't compare people to each other!"
Hua Ling sighed.
Zhong Yue also nodded. "It's just that his brain is so powerful. It's a pity that he didn't come to work with us on photocatalysis. If he had a breakthrough, Teacher Zhuo and Teacher Shu would be smiling even if they fell asleep, right?"
"He's a genius. The thinking of a genius is always something we can't understand."
Lu Fei sat next to Chen Guang and patted his shoulder. "Shameless. You obviously used magic to cheat, and you still have the face to talk about the Nobel Prize. Why don't you go to heaven?"
Chen Guang coughed. "Sister Lu Fei, don't touch me. Don't look at how relaxed I look right now. I'm just pretending. More than a hundred thousand cubic meters of sewage is really not a joke. The resulting sludge is hundreds of tons. I even used up my Earth Elemental MP! "
"MP?"
"It's mana! You don't know how much mana it burns. I didn't even use any endurance equipment! "
"Do you need me to give you a mana buff?"
"Sure. Bring me a big mana potion while you're at it. Okay, okay. I have to meditate to recover my mana. Help me keep an eye on me. Don't let anyone disturb me. "
Chen Guang really didn't talk nonsense with Lu Fei. At this moment, his Earth Burner ability completely covered the entire sewage treatment plant. At the same time, it solidified the sludge in more than a hundred thousand cubic meters of sewage to the bottom of the pool. This consumed his elemental ability very quickly.
Moreover, this was not an instantaneous release. It required continuous support from the ability. He was fighting against the diffusion of nano-scale molecules. The difficulty was not enough to explain to others.
On the other side, Guo Ming rushed back to the office building in time to meet with the experts and leaders of the review team.
The boss, Chen Guang, did not personally welcome the review team. This made the people in the review team feel uneasy, but they did not say anything.
Although everyone now knew that he was the boss of Xiaguang Environmental Protection and the person behind the scenes of Tongshan Industrial Sewage Treatment Plant, Guo Ming was currently the general manager of Xiaguang Environmental Protection on the surface. He had full authorization from Chen Guang and could represent him in all matters within Xiaguang Environmental Protection.
Just like when others came to Microsoft to discuss business, it was already the highest level of courtesy for Microsoft to send their CEO. There was no reason to let founder Bill Gates do all the work.
However, everyone knew that Chen Guang, who wanted to review Tongshan Industrial Sewage Treatment Plant, was a topic that couldn't be avoided.
After the review team leader, Expert Li, got out of the car and instructed others to arrange the equipment and instruments. He went straight to the conference room accompanied by Guo Ming.
On the way, Expert Li asked tentatively, "Is Mr. Chen in the plant today?"
Guo Ming did not intend to hide it from him. Soon, this group of people would meet Chen Guang at the water inlet. He pretended to be very distressed. "Mr. Chen is at the water inlet. He has been sitting there for two days and two nights. Sigh, he refused to come down no matter what we said. We couldn't persuade him."
