Wang Xiaosong smiled slightly: "The preparation of laughing gas is not complicated. Ammonium nitrate melts naturally at 169 degrees Celsius and decomposes into nitrous oxide and water at 220 degrees Celsius. Therefore, the technical difficulty lies in the aspects of collection, packaging, process safety, and explosion prevention.

Although Ma Weizhou and the others are all reckless, this does not mean that they do not spare their lives. They also make money to spend their lives, so I concluded that they would either build a fully equipped factory on their own or rely on other large companies that could be relied upon. ”

"So you're saying that they might have found some chemical companies with deep backgrounds to help them with production?" Xu Ning said.

"That's right, you've searched all the private chemical factories in Binlai County that have the conditions to produce, but you still haven't found them, so there's only one possibility.

Of course, we can also use technical means to detect it. When I was the head of the Binlai County Environmental Protection Bureau, I introduced an air quality monitoring system.

At the beginning, it could only be tested for the county and its surroundings, but after about a year, Director Xiao has perfected the whole system.

We can easily locate the location of the laughing gas factory by looking for places where nitrogen-containing exhaust emissions exceed the standard. Wang Xiaosong said.

Xu Ning was suddenly overjoyed: "Then how long will this take?"

"Time is running out, let's go now. Wang Xiaosong said, and stood up directly, and Xu Ning also quickly stood up. The two of them got into the car together and went straight to the Environmental Protection Bureau.

Xiao Feihu is not at the EPB today, but this does not affect Wang Xiaosong's efficiency in doing things at the EPA. On the one hand, he himself has been the leader of the place for a long time. On the other hand, now that the Binlai New Area Environmental Protection Bureau has been established, Wang Xiaosong has become the rightful leader of the place.

Seeing that the director of the environmental protection bureau of the new district had arrived, the employees here were quite cooperative, and soon handed Wang Xiaosong a test report.

"The report is presented in the form of charts, and here is the map of Binlai County, but we have already marked out all the places where the nitrogen exhaust gas exceeds the standard. A worker said.

Wang Xiaosong looked at the five or six red dots on it, and then asked: "What is the reason why the content of these nitrogen-containing exhaust gases is relatively high, and why is this not remarked?"

The staff was sincerely frightened, hurriedly apologized, and then took the report aside, and after a while, said: "Director Wang, we have already checked this." Most of them are chemical companies, pharmaceutical companies, and food companies.

Although the relative content is too high, it is also discharged in accordance with our regulations and does not exceed the standards we require. ’

Wang Xiaosong nodded, then pointed to the last red dot on it and said, "What about this red dot? Why is it also exceeding the standard here?"

"There are many factors for the emission of nitrogenous gases, and sometimes a large amount of nitrogenous exhaust gases will be generated when the high-voltage power supply is used. After all, most of the air is made up of nitrogen, so. ”

Without waiting for the employee to finish speaking, Wang Xiaosong said with some dissatisfaction, "It's good to just say that you don't know." ”

Seeing Wang Xiaosong's unhappy look, the staff hurriedly lowered their heads: "I'm sorry Director Wang, we don't know about this for the time being." But I'll find out as soon as I can. ”

Wang Xiaosong waved his hand: "Forget it, this is not in a hurry." ”

While speaking, Wang Xiaosong took out his mobile phone, opened the map of his mobile phone, and after looking at it, he suddenly let out a laugh.

Several people next to him were taken aback, and turned their heads to look at Wang Xiaosong, but Wang Xiaosong just smiled to himself, and then pulled Xu Ning, pointed to the map and said: "Look at what kind of place this is? This red dot is the last place where nitrogen-containing exhaust emissions exceed the standard, but the reason is unknown." Look here, what's the map saying it's for?"

Xu Ning frowned and looked at it, and muttered, "Tianyi Packaging Factory." Is this a packing plant?"

Suddenly, Xu Ning was shocked: "I understand, what you said before, the most troublesome part of this factory is not the production of products, the most important thing is the packaging! So after production, they send the gas tank to the packaging factory for packaging! The final product is produced from here!"

"That's right, what to do next, I don't need to tell you. Wang Xiaosong said.

Xu Ning nodded again and again: "I heard before that you were born as a special forces, and you are a good hand at conducting investigations, but I thought it was just someone else's talk." But today, it seems that you are indeed a master of scouting, and I am convinced!"

In the end, the two men left the EPA and agreed to let Xu Ning remember to inform Wang Xiaosong of his findings at any time.

After solving this matter, Wang Xiaosong returned to the construction office, Gao Yang and Lin Xiaoran had already brought up the plan for the transformation of the rural biogas digester project, Wang Xiaosong looked at the plan, and unconsciously it was late at night.

Wang Xiaosong stretched his waist and began to draft an application, preparing to apply for the project as a joint project between the Environmental Protection Bureau and Huanyu Environmental Engineering Company.

Once the project can be approved, it will be equivalent to solving the two major social problems of urban sewage and rural energy supply at one time. In view of this, Wang Xiaosong also believes that it is normal for him to work a few more shifts.

Over the next nearly a month, Wang shifted his focus to the biogas digester project. Every day, he travels back and forth between the new district government and Cui Jianguo's company.

Seeing that things were progressing steadily step by step, at this time, Xu Ning's call hit Wang Xiaosong's mobile phone.

Wang Xiaosong was very surprised: "Xu Ning, come to me so soon." Did you find anything?"

Xu Ningen's voice: "It's a discovery, and it's a big discovery." Director Wang, this matter involves a wide range of issues, and we have to talk to each other face-to-face. ”

Wang Xiaosong agreed without thinking, and that afternoon, the two met in Wang Xiaosong's office. As soon as they met, Xu Ning said directly: "Director Wang, this time the matter is big. ”

Wang Xiaosong frowned: "You say, what level has it been." ”

Gao Yansheng, deputy director of East China Yongxing Nitrogen Fertilizer Plant. Xu Ning said.

Wang Xiaosong frowned: "Yongxing Nitrogen Fertilizer Plant? ”

Xu Ning cleared his throat and reported the detection of this incident to Wang Xiaosong 1510.
