I thought I was still Long Aotian

When everyone learned that the fluorescent blue substance on the water was not gamma rays, they all turned back to the shore.

At this time, the equipment had been running for more than half an hour, and Hao Wu did the water sample test again, and found that the pollution indicators had all decreased, but the methyl mercaptan had not changed significantly.

"Boss, look at this." Hao Wucai handed the data report to Yuen Long.

After Yuen Long browsed it, he passed it to Director Li, "Is there a fertilizer factory in the upper reaches of this river?"

Director Li nodded, and looked at the data. The content of total nitrogen, total phosphorus, lead, mercury, and coliform bacteria decreased by one-third, and indicators such as sulfate and oxides also dropped significantly. Only the value of methyl mercaptan stay high.

Director Li was a little puzzled, how did Yuen Long determine that it was from the fertilizer factory, "If your water purifier can filter other substances, then it should also be able to filter this methyl mercaptan. Why is it the only one with such high data?"

Yuen Long said: "Our water purifier is said to be filtering, but in fact it only accelerates the biodegradation reaction of the water body. Other values ​​​​have decreased, except for the value of methyl mercaptan.

This is the same as people eat. Cream cake is the favorite of many people, but people must eat it 24 hours a day, no matter if it is chocolate, strawberry or matcha, no matter how delicious it is, they will always eat it. I can't eat it either.

Yuen Long: "The concentration of methyl mercaptan produced in the production of chemical fertilizers is about 0.200-0.280 mg/m0.060, and the concentration of methyl mercaptan produced in the production of pesticides is about 0.0120-[-] mg/m[-]. As for pharmaceutical, food and synthetic material factories The concentration used is lower than this."

Yuen Long pointed to the data report in the hands of Director Li: "From this data, the concentration of methyl mercaptan is as high as 0.189. Excluding the volatilization amount at this distance, it is obvious that the fertilizer factory about 30 kilometers away directly discharges sewage into the canal. Now check the upstream fertilizer factories that are still working overtime, and you should be able to find the source of the pollution soon.”

"That's really great!" Secretary Qian said happily. He called his secretary to get a phone number and personally contacted relevant departments to carry out a surprise inspection of the upstream fertilizer factory.

Director Li also called his scattered colleagues and asked them to cooperate with those departments in the inspection.

If we can find the source of the pollution, stop the discharge, and then purify the river water, we will definitely be able to clean up the pollution in the wetland before next Monday.

However, things didn't go so well.

More than three hours later, Director Li's colleague called and said that there were two fertilizer factories working overtime, but both of them had regular sewage treatment equipment, and there was no secret sewage discharge.

Director Li: "Mr. Yuan, could it be that someone from a factory further away discharges sewage?"

Yuen Long frowned: "Impossible, if it is farther away, the concentration cannot be so high."

For a while, everyone was worried.

Sewage treatment has always been a headache for major factories. As national standards are in line with international standards, chemical factories are spending a lot of money, and production costs continue to increase. However, the products they sell encounter severe market competition.

If you want to reduce costs and expand market share, secretly discharging sewage is a trick.

It was very late, and most of the surrounding factories had already closed get off work. I don’t know who else secretly discharged sewage into the canal in Yuen Long before, but the most powerful one at this time must be the fertilizer factory.

Yuen Long: "I still have another way, but I can't do it until tomorrow morning."

"What method?" Secretary Qian and Director Li asked at the same time.

Yuen Long chuckled: "You'll know when the time comes, it's 1 o'clock in the morning, everyone is tired."

Director Li stroked his hair anxiously, "Oh, Mr. Yuan, don't be a fool. What is the solution?"

Secretary Qian breathed a sigh of relief when he saw that Yuen Long was confident, "Okay, it's getting late, let a few people stay here on duty to check the equipment, everyone else should go back and rest, and come back tomorrow."

Director Li: "But, we are running out of time!"

Yuen Long: "The two leaders can rest assured that as long as the source of pollution is stopped, the purifier can purify 1 kilometers in one hour."

In other words, if the polluting company is really 30 kilometers away, it only takes more than 10 hours to purify all the sewage they discharge.

Secretary Qian's eyes lit up, he laughed and patted Yuan Long on the shoulder, "Mr. Yuan, if it's true as you said, if your equipment is going to be mass-produced, give me a batch first, it's better than a sewage treatment plant! "

Yuen Long replied: "Okay, then I will go back and prepare for production."

Regardless of whether it was a joke or having fun, the two leaders, Qian and Li, relaxed a little.

Early the next morning, Hu Xizhou went to pick up Yuen Long and the others with great enthusiasm.

Yuen Long and his colleagues were about to go downstairs to have breakfast, and he was a little surprised to see him, "Why are you here so early?"

Hu Xizhou asked embarrassedly: "What method are you talking about, can you tell me in advance?"

He didn't sleep well last night, thinking about what miracles Yuen Long could do.

At the Crescent Lake Wetland, the high-viewing rocker was already shocking, and then the strawberry live streaming incident, it can be said that it caused a sensation all over the country. The strawberries in that village were almost sold out, and the fruit farmers got real benefits.

Yuen Long: "You'll know when you see it later, let's go and have breakfast with us."

Hu Xizhou smiled and said, "Okay, I just haven't eaten yet."

This time, Yuen Long brought a large metal box. When he arrived at the polluted canal wetland, he asked two mechanical engineers to lift the metal box out of the car.

"How about the water quality data?" Yuen Long asked the staff on the night shift.

"Methyl mercaptan still exceeds the standard." The staff handed him the report and couldn't help yawning at the same time.

"I just have breakfast over there. After you finish eating, go back and have a good rest. Today is your holiday, so you don't need to come here again." Yuen Long said.

"Okay, thank you boss." The staff member stretched, turned and left happily.

Hu Xizhou looked at them sideways, and sighed softly: "You are very kind to the employees."

Yuen Long: "That is, I still rely on them to work for the company."

While the two were chatting, the metal box was opened by the mechanical engineer, revealing a knee-high white machine.

Hu Xizhou: "Ah, I've seen this thing before, isn't it the carrot robot produced by your company?"

After the Strawberry Incident, Hu Xizhou did some research on Yuen Long, and found out that Carrot Technology is a famous high-tech company in City B, and that they had produced intelligent robots.

Hu Xizhou has already passed the age of liking Gundam, but this does not prevent him from being happy and excited after seeing the robot.Maybe there will always be a little boy in every man's heart. He fell in love with the carrot robot the moment he saw it.

Hu Xizhou stepped forward quickly, raised his hand and gently stroked the shell of the carrot robot: "Oh, look, this is a real robot!"

Yuen Long: "That's right."

This radish robot is the same type of intelligent robot as the RV in the Pingfu Village factory. It has super computing power and self-learning ability, and it is considered the lowest level of intelligent equipment.Before coming out, he made a small modification to it, just waiting for this time to prepare for a rainy day.

Hu Xizhou asked curiously, "You want it to investigate the source of pollution?"

Yuen Long nodded: "Yes."

Hu Xizhou was surprised: "Could it be like a robot in a sci-fi movie, detect water quality, and then start tracking?"

Yuen Long laughed: "What are you thinking, this is just an underwater robot!"
