Long Zihan asked again: "How is electroplating wastewater usually treated?"

"So, we're all doing redox reactions with ferrous sulphate and hexavalent chromium, and then creating flocs under alkaline conditions. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 Info and other flocs come to the surface, so that the water becomes clear. ”

(It's just a novel, you don't have to worry about the time and age of the emergence of this technology.) Don't take it seriously!)

Long Zihan frowned slightly, and asked, "Can you take us around the neighborhood?"

The person in charge was slightly stunned, then pursed his lips and said, "Okay, I'll take a few people around the factory." ”

Following the person in charge, Long Zihan and the three of them observed while walking.

The person in charge is gushing about the workshops along the way, and even more exaggerated and contrived to say that their factory is a conscientious enterprise.

And the three of them obviously didn't take his words to heart, and let him sell melons and boast there.

At this time, the person in charge walked to the door of a workshop and said, "This is the workshop for treating wastewater." ”

Walking in, Long Zihan swept around, pointed to a machine and asked, "This machine doesn't seem to be working, right?"

"Ah......" The person in charge raised his hand and touched his neck, and said vaguely: "This machine is not very useful, and it will only be turned on when it can be used." I don't need ...... yet."

Long Zihan stared at the face of the person in charge for a while, and then said, "We want to take some wastewater samples, don't you mind?"

The person in charge shook his head and said, "Don't mind, Long Shao, please do it." ”

After extracting, Long Zihan visited for a while, checked around, and finally said, "After bothering for so long, we should also leave." Thank you very much, farewell!"

The person in charge looked overjoyed, and he hurriedly said, "I'll send Long Shao." ”

"No need, Your Excellency is busy, and I'm already embarrassed to delay for so long. Then, Long Zihan didn't give him the slightest chance to be polite and refute, turned around directly, looked at the two, and said, "Erin, Mo Bei, let's go!"

The person in charge suddenly looked ugly, but it was not easy to attack on the spot.

He raised his voice and greeted: "A few people go slowly, then I won't send it." ”

After the three of them left, the person in charge took a sip and said, "What!"

This is the power of a seasoned businessman, even if there are countless dissatisfactions in his heart, he will never openly offend others on his face.

And especially a high-ranking disciple like Long Zihan, who has a very wide range of paths, is the object of his dare not easily offend. So, this kind of face-losing thing, he can only get through it.

On the way out, Erin thought in pieces: "That bald man must be playing sloppy with us, and when he answered your words before, he either pursed his lips or wiped his neck, these are all mechanical reactions when lying." There must be something wrong with the machine that stopped. ”

Mo Bei guessed: "Perhaps, he didn't treat the electroplating wastewater as well as he said." ”

Long Zihan said: "That person is a shrewd businessman, and it is because of problems that it is even more impossible to expose his old background." Therefore, it is completely normal for him to hide and tuck, and there is no need to dwell on this issue. ”

Erin winked at him and asked, "You just deliberately gave him a look on his face, so that you wanted to probe again, right?"

Long Zihan "looked back and smiled" raised his eyebrows and said, "Knowingly ask!"

Seeing this, Mo Bei couldn't help but shiver, and whispered: "Why do these two people pretend to be intimate, which makes people feel like a yin wind?"

Immediately, Mo Bei received the white eyes of the two people.

He touched his nose and reluctantly followed.

On the way out, Long Zihan and the three of them did not follow the route they came, but walked around the "garden" generously.

At this time, they heard the sound of two people arguing.

"What now?"

"What can I do? The report is up, and now I have lost something, but it can be big or small. If we don't get it right, we're going to be suspected of being thieves. ”

"Are you stupid, report it, isn't this our own compensation?"

"But ......"

"But what? These are all leftover goods from last year, and no one cares if they are useless, so what if there is one less bag? If you don't say it, I don't say it, who knows?"

The conversation between the two people was listened to word by word.

Long Zihan walked out, looked around, took the opportunity to observe the terrain and environment, and asked, "What did you lose?"

As soon as the two of them saw that someone found out, they immediately became nervous.

One of them asked, "Who are you?"

Long Zihan took out his police ID card and said, "We are policemen!"

Mo Bei had some doubts in his heart: Could it be that at this time, his eldest brother wants to take the initiative to take the initiative to take up a theft case and postpone the murder case for the time being? This is not his style.

There is no waste water leaking inside or outside this electroplating plant, and they may be going in the wrong direction.

But Long Shao generally doesn't do useless things and delay big cases.

Even if there were other cases, he would call another team to investigate. What's wrong with him today?

"What?

Hearing Long Zihan's introduction, these two people immediately became anxious.

"We just found out that we lost something, why did you come so quickly? Did the director find out a long time ago, so he called the police?"

"Comrade policeman, we are wronged!"

"That's it, comrade policeman, we are really wronged! We have been diligent and conscientious for so many years, our hands and feet are clean, and we never dare to swallow things privately. ”

The two of them were like frightened birds, immediately explaining to themselves.

Long Zihan explained: "I came to the electroplating factory to investigate another case, and we all heard what you said just now. Now can you tell me 1510 what you lost?"

Another person asked in a panic, "We just found out that we lost a bag of copper pieces." ”

Long Zihan asked, "Where did you put the bronze piece before?"

"It's been down the wall outside our workshop warehouse, and that's it!"

Long Zihan looked in the direction the man pointed, and there were a lot of large and small things under the wall, but because of the placement, they didn't seem to be very eye-catching.

Now it seems that among the easiest items to take, the most valuable is the bag of copper.

Long Zihan looked at these things and asked very casually, "Why don't you put them inside?"

"There were a lot of large items in it at that time, all of which were received from new orders this year. And the handling of large items needs to be open and bright, so some small pieces, or inconsequential things, we will put them outside. Moreover, the bag of copper pieces was also left, and no one wanted it, so it was temporarily put outside. ”
