Three days later, in a French restaurant, Ling Shizhe met Daniel again. Forrest, at this time, Forrest was wearing an orthodox suit, and his body was full of a gentlemanly demeanor, which was very different from the bad old man when he first met him. Pen ~ fun ~ pavilion www.biquge.info

The table was full of delicious and hearty French meals, and unlike Forrest, who was eating heavily, Ling Shizhe had no interest in the food in front of him, and he was now flipping through the wetland environmental survey report handed to him by Forrest.

Forrest's report is detailed, and Biambrera has done a much more detailed environmental survey herself, because this report has been documented by Forrest since '72.

Reading page by page, Ling Shizhe gradually had a clear answer to the reasons for the excessive heavy metals in the constructed wetland.

When the treated sewage is discharged into the wetland, the peatland will filter the sewage again, and the remaining heavy metal ions in the sewage will be absorbed by the peatland, and although the plants planted on the peatland have the ability to further absorb heavy metals, the plant's ability to absorb the heavy metals in the peat is limited after all, and it cannot keep up with the accumulation rate of heavy metals. Heavy metals in the wetlands are exceeded.

Continue to flip, the following is the investigation report on the heavy metal content of wetland plants, and the heavy metals contained in all wetland plants also exceed normal values, and there is a tendency to further aggravate, which makes Ling Shizhe frown.

Although wetland plants have a strong ability to absorb and transform heavy metals, but can not absorb indefinitely, they have an upper limit, once the upper limit is exceeded, there will be large-scale death, the report of these wetland plants has some bad signs, some plants began to wither and die, if you do not come up with effective measures, this wetland is really ruined.

But what to do, Ling Shizhe didn't think of it. Just such a small amount of heavy metal residue can cause such a big harm, Ling Shizhe remembered that there did not seem to be this problem in Germany in his previous life, and the artificial wetland they built has always been good. Everyone uses the same way to deal with it, why is it that Germany is fine, and when it comes to him, there is a problem?

There must be a key link missing, and this link will only appear in this situation, what is it?

Looking at Daniel, who was feasting on a large block. Forrest. Ling Shizhe's heart moved, and said: "Professor Forrest, your investigation report is very detailed, much more detailed than ours, I want to hire you as the chief scientific advisor of Ambrera Integrated Environmental Company, I wonder if you are willing?" ”

Ling Shizhe didn't believe that Forrest made such a detailed investigation report, so he didn't have any ideas in his heart, so he threw a stone first to ask for directions, and threw out the title of a scientific advisor first, and saw how he answered.

Forrest smiled. "I'm more than happy to serve you, but how much do I get paid?" ”

"$300,000 a year." Ling Shizhe investigated, Daniel. Before Forrest retired, his annual salary was only $150,000 at most, and his annual salary of $300,000 has more than doubled.

"It's a good salary, but unfortunately I'm retired." Forrest smiled faintly.

Damn, an annual salary of $300,000 can't satisfy your appetite, how much do you really want?

"Tell me about your conditions." Lawrence, who was sitting next to Ling Shizhe, spoke.

Forrest finished the last bit of caviar on the plate, wiped his lips with a napkin and said, "I'll retire." I opened a private laboratory specializing in the study of the ecological balance between plants and animals, and the laboratory was funded mainly through social donations and corporate sponsorship, and my first sponsor was Dow Chemical. My contract expired last year and I'm looking for a new sponsor but haven't found it yet. ”

"Understood," Ling Shizhe nodded and said, "Okay, I'll take over from Dow Chemical Company, and I'll sign you a ten-year contract." I'm going to give you $500,000 a year to sponsor the lab, and I'm going to hire you as the lead consultant for Ambrera Integrated Environment. ”

"Deal!" Daniel. Forrest quickly reached out and said, "I like a generous boss. ”

Ling Shizhe stretched out his hand and shook him heavily, and said, "But I want to state in advance that our company never raises idlers, if you can't solve the problem, the contract will be terminated, understand?" ”

Forrest laughed and said, "If I can't solve the problem of excessive heavy metals in the wetland, I don't need you to remind me, and I will roll up and get out of the way." ”

Seeing that the matter had been discussed, Ling Shizhe stood up and said, "The contract will be delivered tomorrow, inform your lawyer." ”

After saying that, Ling Shizhe and Lawrence left.

Getting into the car, Lawrence said, "A greedy old man. ”

"It's very greedy, but he's smart, isn't it, he knows that everything has to be done in moderation, so he doesn't make very excessive demands." Foster replied to Lawrence as he took off his headphones.

Although he did not go up just now, he was in the car to monitor the entire negotiation process.

Alison, who was sitting opposite, said: "Boss, you give too much, I understand, Dow Chemical only signed a three-year contract with him, and the annual sponsorship is only $100,000, and you lack him $500,000 a year, and you have to spend $300,000 to hire him as our consultant, $800,000, what a greedy guy." ”

"Foster, what do you think?" Ling Shizhe didn't answer Allison's words, but asked Foster next to him.

"It can be done!" "The biggest problem now is how to solve the problem of excessive heavy metals in the wetlands, as long as he can solve this problem, this money is nothing, because we can get more," said Foster. ”

Ling Shizhe was satisfied, Foster can be regarded as talking about his heart, what is the most important thing now, of course, is the problem of excessive heavy metals in the wetlands, as long as Daniel. Forrest can solve the problem of excessive heavy metals, not to mention 800,000 US dollars per year, even if it is 8 million US dollars, Ling Shizhe will not hesitate to come out, because the future of sewage treatment is a huge market, think about it Mobil and DuPont, as long as they can win one of them, they can make Ambrera Integrated Environmental Company full, compared with the huge market, 800,000 US dollars is really nothing.

Not to mention that Ling Shizhe has a word first, if he can't solve the problem, Ling Shizhe won't pay a penny. At that time, even if Forrest was a liar, Ling Shizhe would have no loss at all.

Two days later, in the office of Ling Shizhe, the headquarters of the "Water Cube", in the presence of the respective lawyers of both sides. Ling Shizhe signed his name on the contract.

Then, the two parties exchange contracts, and after signing, the contract is officially effective.

After everyone left, Ling Shizhe said to Daniel. Forrest said: "The contract has been signed. Now it's time for you to say it, right? ”

Forrest shrugged his shoulders and took out a document from his briefcase and handed it to Ling Shizhe.

Ling Shizhe took the document, only looked at it twice, then stood up and said in surprise: "Raise shrimp, raise snails!" ”

"Yes, it's shrimp farming, snail farming." Forrest replied with a smile.

In terms of Ling Shizhe's poor agricultural knowledge, his perception of lobsters is that he has eaten crayfish in his previous life.

In fact, shrimp, like crabs, contribute a lot to the oceans and lakes, and their oceans and lakes are regulators of heavy metal content. Like crabs, shrimp are constantly sucking in water throughout their lives, and when the water passes through their lungs, heavy metal ions are sifted out, and the content of related ions in the water is very low.

The heavy metals absorbed by the shrimp will be converted into other substances by the shrimp, and finally completely absorbed by the shrimp, as you will know after watching the BBC's deep-sea documentary, which is thousands of meters below the deep sea. An active volcano under the sea is billowing black smoke, and many people think that in such an environment, there will be no life, but a miracle has happened. A large group of shrimp and crabs are clinging to the "black chimney", and they live by sucking the toxic substances expelled from the "black chimney".

Shrimp and crabs generally live in the tropics at low latitudes, and few shrimp survive in high latitudes; Yes, they are generally cold-water shrimp that live in the ocean, and freshwater shrimp are extremely rare, and even if they do, they have extremely high requirements for water quality. Because the ability of these high-latitude freshwater shrimp to deal with heavy metals has long been degraded, and they cannot adapt to the special environment of the artificial wetland, Ling Shizhe has not farmed shrimp in the wetland since the beginning.

Shrimp, is shrimp, only shrimp can solve the problem of excessive heavy metals, by the way there are snails, the growth rate of shrimp in high latitudes is very slow, the processing capacity of heavy metals will decrease a lot, if this is cultivated in the wetland snails, the problem can be perfectly solved.

The snail also has the ability to clean up heavy metals, and it also has the effect of cleaning ponds and paddy fields.

The strongest ability to clean up heavy metals is crayfish, such as the United States crayfish and Australia's red crayfish are among the best, among which the United States crayfish is Ling Shizhe's best choice.

It is very viable and can survive in Europe, Africa, Australia, Canada, New Zealand and the United States.

There is also a very strong anti-pollution resistance of crayfish, in the water containing highly polluting toxins, it can still survive, this is because the crayfish in the green shrimp is working, scientific research has proved that the body astaxanthin content and its ability to resist the external harsh environment is positively correlated, that is, the higher the body astaxanthin content, the stronger its ability to resist the external harsh environment. The content of natural astaxanthin in the body of crayfish with the color of jujube red is several times that of shrimp.

As a result, crimson crayfish can survive and reproduce in foul silt, while pale red prawns do not survive easily even in clear water. Crayfish cannot produce astaxanthin on its own, mainly through the food chain - edible microalgae and other foods to obtain astaxanthin, and continue to accumulate in the body to produce super antioxidant capacity. Astaxanthin can effectively enhance the ability of crayfish to resist harsh environment and improve reproductive ability.

Therefore, astaxanthin is a strong guarantee for the tenacious vitality of crayfish, and it is difficult for crayfish to survive in an environment that lacks these astaxanthin-containing microalgae. This also gives people some illusions that crayfish have to live in a dirty environment.

Now that we know the solution, we have to act quickly and hand over the information to Lawrence and Cai Zhiyang, one is responsible for purchasing the chicks of crayfish in the United States, and the other is responsible for the procurement of Chinese snails.

Why buy Chinese snails, instead of purchasing snails from other regions, the reason is that Chinese snails belong to senior consumers of heavy metals, it has a strong ability to decompose heavy metals, and the crayfish in the United States is not, it is only a primary consumer of heavy metals, and it does not have the ability to convert heavy metals into its own nutrients, and the heavy metals it absorbs are concentrated in the head, and the heavy metal substances contained in the head of the crayfish after death can be decomposed by the snail.

Ling Shizhe instructed the two of them to personally supervise the purchase of crayfish and snails, because Australian crayfish look very similar to American crayfish, but they are not the same animal, the former can only live in subtropical and tropical regions, and the latter can survive in high latitudes, once you buy the wrong one, it will be troublesome.

The Chinese snail is the same, it looks very similar to the South American snail, but the snail contains a lot of parasites, such as strongyloides, which can erode the central nervous system of the human body, causing headache, fever, neck stiffness and other symptoms, and in severe cases, it can cause dementia and even death.

The Sinochem snail does not have these problems, and its environmental adaptability is super strong, and it can also survive in Canada at high latitudes, and the Fushou snail will die if the water temperature is lower than 6C.

But as soon as the notice was sent, Cai Zhiyang came over, and he told Ling Shizhe that the Chinese field snail is also called field snail and fragrant snail, and the English name is mudsnail. It is not only distributed in China, but also widely distributed in North Korea and North America, so there is no need to buy it in China.

Hey, he made a common-sense mistake again, Ling Shizhe hurriedly apologized to him, but in the end he asked him to be in charge of the procurement in person, the reason was that he was afraid that the white employees below would not be able to distinguish the difference between Fushou snail and Chinese snail, Cai Zhiyang is Taiwanese, his ancestral home is in Hubei, and he has not eaten less snails since he was a child, so only he can tell the difference between snails and Fushou snails.

As soon as Cai Zhiyang was sent out of the door, the phone in the office rang, Ling Shizhe lifted the phone, and John on the other end of the phone. Jim told him, "Boss, PHS will be in operation in three days. (To be continued.) )
