A week after inspecting the site, the group arrived at the oven, and the office of the Luyuan Ecological Restoration Engineering Company held a meeting to discuss the plan.

The headquarters of the Luyuan Ecological Restoration Engineering Company is in the provincial capital, but now it is only an empty shell, and there are no people. Previously, because of poor management, internal strife was fierce, and many people who really did things left the company one after another. It was also because of this that Cao Zhengyang had the opportunity to inject capital into it. However, Cao Zhengyang himself did not plan to engage in this industry, so he thought that the project of Longtoushan would be over, and as for whether the company would live or die in the future, he didn't think too much.

He Tianqi, who really has feelings for this company, has been an employee of this company before, and has experienced many turmoil in many companies, but he has never given up. He is also one of the founders of the company, and as a technician, he does not have much money to invest in it, but only holds a symbolic 5% stake. As an insider, he couldn't speak in the company's disputes, and could only watch the company go from prosperity to decline, but he couldn't do anything.

Cao Zhengyang's capital injection reinvigorated his entrepreneurial passion. He also knows his flaws, as a pure technical controller, he really has no enthusiasm for money and relationships, and he needs support in these aspects very much. And the original company has basically gone out with these abilities, and those who are left behind are some infighting masters and fools. After Cao Zhengyang injected capital, he cleaned up these people, leaving only him, and rebuilding the team according to his ideas. This made him feel that what he had learned in his life could finally be put to use.

He also came to the small county town of the oven with the whole team. In his heart, for the Longtoushan project, it is also worth temporarily moving from the provincial capital to the county seat. The goal, of course, is to go back to the provincial capital.

Others, either like He Tianqi, or similar to Zhang Yuerong, are stationed in this office for this project. This was deliberately arranged by Cao Zhengyang, and it was also convenient for future management.

This office has three separate small offices, one for chairman and general manager Cao Zhengyang, one for chief engineer He Tianqi, and one for executive vice president Ren Feng; There is also a large general office, which is where other engineering personnel are concentrated; There is also a meeting room for entertaining guests and holding meetings. Cao Zhengyang and Ren Feng will not stay in the office for long. Cao Zhengyang's office was simply changed to a mahjong room, and when everyone was on vacation, he could find mahjong friends to play cards here. And Ren Feng's office is usually used for finance, that is, Zhang Yuerong usually uses this office.

The meeting is, of course, in the conference room.

This time it was supposed to be an internal meeting, but there were two more "outsiders" Shen Yi and Fang Xiao, although they had met last time, this time they specially introduced the two of them again.

The meeting was mainly to discuss the plan, and the text was printed in advance and shown to Cao Zhengyang and Ren Feng and others, but He Tianqi was still asked to introduce it to everyone on the spot, mainly because some professional things need to be explained to everyone.

The plan divides the remediation area into two areas, one for the mine, one for the concentrator and the contaminated farmland.

The restoration of the mine itself is relatively mature, with slope protection and rock formations fixed; Dredging ditches, planting trees with turf, keeping the soil on it. Basically, He Tianqi explained that there were no major objections from the Du family.

The area of the concentrator is not so easy to decide. The soil is heavily polluted and has had a significant impact on the lives of the surrounding villagers through the transfer of groundwater. And the remediation of this soil pollution is very troublesome. Generally, it can be simply divided into two methods, one is in-situ repair and the other is ex situ repair.

In-situ restoration, as the name suggests, is a restoration that takes place directly at the original location. However, due to the fluidity of groundwater, this method is slow to work and requires a large area.

Ex-situ remediation is the excavation of contaminated soil to another place for treatment. In this way, as long as the polluted soil is removed, the pollution to the local area will disappear. This requires a place to store and dispose of these contaminated soils, and the cost of excavation and transportation is high, and the excavated potholes need to be filled in time, which is relatively uneconomical.

He Tianqi suggested that the in-situ remediation method should be adopted, so that the total investment cost is much lower and the relative competitive advantage is relatively competitive.

But everyone is worried about one thing, in-situ remediation is not immediate, and groundwater pollution is often solved after twenty or thirty years. Originally, this project was based on the rescue of these villagers, but the result may not be seen in more than ten years, what will these villagers think?

If off-site remediation is used, where will the contaminated soil be disposed of? Where can I store these soils without worrying about contamination of the local soil? What about the fees?

Cao Zhengyang listened to everyone's analysis, it is really a first two big! I was so naïve that I didn't know it would be so troublesome! He asked Ren Feng to share his opinion.

Ren Feng thought for a while and said, "Listening to He Gong's introduction, I also think that it is better to use in-situ restoration. The main problem of the villagers is the problem of water, and it would be good if the water was solved. The water they drink now comes from other villages, and the trouble is that the trouble can be roughly solved. However, other water uses polluted water, which still has a lot of contact with the skin, and the impact is not small. In addition, if the crops in the field are irrigated with polluted water, there will definitely be residues, and it will be a big problem to eat them in the stomach.

So my idea, first of all, is to find a way to give these villages tap water, so that they can use clean water. The second is to take good care of local crops, and if there are indeed residues, do not plant or replant other cash crops. ”

Cao Zhengyang interrupted him: "This place is not close to the county seat, and the cost of laying water pipes is very high, and the villagers here will not agree to pay additional water bills." Also, they complained that their fields were flooded and they couldn't plant them, and they wouldn't let them plant any other land, so they had no choice but to rebel? ”

Ren Feng explained: "The population of these villages is not too large, and it may not be as convenient and cost-effective as building a small water plant to bring tap water from the county. Whether it is the problem of expenses or farming, it still depends on their income, if they can increase their income, many things will be solved. And our project should have that potential. In this regard, you can listen to the advice of Professor Shen and Fang Gong! ”

Everyone turned their eyes to Shen Yi and Fang Xiao to see what kind of speeches they had.

After Fang Xiao whispered a few words with Professor Shen, he said: "I studied circular ecological economy with Shen Lao in graduate school, and I actually have some research on waste mines. It is also possible to build a circular ecosystem. Mines like Dalongshan, which are high in heavy metals and lacking in other nutrients, can inhibit the growth of some plants, but this can be solved by screening specific plants and improving the soil environment.

These plants are used for cultivation, but there are risks, and it is likely to cause an enrichment effect in the animal, resulting in excessive heavy metals and inedible. However, whether it is a plant or an animal, the enrichment of these harmful components is also organ-divided. For example, the fruits, leaves, trunks and roots of the same plant have different levels of the same heavy metal. As long as we do a good job of screening, we can still select the beneficial parts for breeding, and the parts with high content can be used for other purposes. In this way, the entire ecological restoration area can actually generate economic benefits, which can be used to subsidize villagers in polluted areas. ”

As soon as everyone heard it, they understood what it meant, that is, to make money to subsidize the villagers while restoring the ecology, which is a way.

Professor Shen also followed Fang Xiao's words and said: "I would like to add that the circular ecological economy is not only the scope of agriculture such as planting and breeding, but also includes industrial production, but how to connect industry and agriculture? The food processing industry is often thought of. But these times are far from enough, any industrial production can provide raw materials through agriculture, which is the development direction of circular ecology! Mine rehabilitation provides such an opportunity, how to turn mining into agriculture? This is one of my directions of thinking, and I look forward to getting answers from the practice here! ”

Professor Shen's remarks did not mention any specific solutions, but they seemed to be a bit pretentious, and made some bluffing concepts, and everyone seemed to understand them. However, because of his status as a professor and the guest brought by Ren Feng, everyone still applauded warmly.

Cao Zhengyang only understood that he could solve the core problem of villagers not making trouble without paying money, and he didn't need to understand the others, so he let these people who understood discuss it specifically. What he cares about is getting this project, which will make it easier for him to open a mine. So he said: "Then do it according to Mr. Ren's opinion, and you will discuss the specific details carefully, and I will leave first if I have something!" ”

In this way, the discussion is indeed more in-depth, everyone has some foundation, and many things do not need to be explained so clearly, and each other can understand each other.

The final plan is the specific refinement of Ren Feng's ideas, and the role of Green Peak ecology has been greatly strengthened, and it has been promoted from its own tree planting and grass bale foreman to the position of the leader. He Tianqi felt a little depressed, but from the perspective of doing things well, it was understandable to do so.

It has also been suggested that the ecologically restored mine can be considered as an artificial landscape and become a tourist spot, which can also obtain certain benefits, and has also been recognized by everyone, and can be carefully planned in the plan.

The final compilation of this plan was mainly based on He Tianqi, and Ren Feng cooperated to provide specific information on planting and the construction of small waterworks.

Ren Feng actually thought in his heart that it would be better to relocate these villages as a whole, but the investment was really sea. He didn't know that Fang Xiao had bolder ideas than him, but now these obviously unattainable ideas were not spoken.
