"This special meow is simply a 'living dictionary of pollution'!"

In the pilot area of heavy metal pollution control in Hunan Province, Qi Zhengluo sensed that the whole person was not good.

This is an old industrial area in the Xiangjiang River basin and the surrounding farmland, along the east bank of the Xiangjiang River is distributed in a long and narrow way, and was identified as one of the 14 fine chemical bases for priority development by the state in the 80s. Today, it seems that this former development advantage is becoming a shackle to Hunan Province's environmental governance.

Wastewater, waste gas, waste residue, especially heavy metal pollution ions, not only caused heavy metal pollution incidents in the Xiangjiang River many times, but also brought serious soil pollution problems.

Qi Zheng didn't have to wait for the test results of the drilling site to come out, and released his divine sense, and the variety of heavy metals in the soil was clear at a glance.

Needless to say, chromium can cause numbness in the limbs and mental abnormalities; lead and heavy metal pollution is one of the more toxic ones, which can directly harm human brain cells; vanadium hurts people's heart and lungs, leading to abnormal cholesterol metabolism; and zinc fever can occur when there is too much zinc......

Very good, worthy of a pilot, typical enough!

Yue Jianping, the person who connected the pilot project, smiled.

To be honest, such a "poisonous land" is really not an exception in Hunan Province.

When the proud "land of fish and rice" was covered with a shadow of pollution, he felt very uncomfortable. "If you want gold and silver, you want green waters and green mountains", this is Yue Jianping's heart, and it is also a choice that Hunan Province has to make.

The "toxin" is in the soil, and the roots are in the ground.

In response to the pollution caused, the province has prescribed a prescription to "shut down and withdraw". However, cutting off the source of pollution is only the first step in the control of soil heavy metal pollution.

"How is it?, is Jiagu sure?" asked Yue Jianping tentatively.

Jiagu undertook a pilot project for the treatment of nearly 5,000 acres of heavily polluted heavy metal land, with an initial capital of 250 million yuan for the implementation of the project, and an average remediation cost of 50,000 yuan per mu.

Don't think it's an exaggeration to invest in the last century, when the island nation used the guest soil method to restore more than 12,000 acres of cadmium-contaminated farmland, a 33-year project that cost $340 million, with an average cost of nearly 200,000 yuan per mu. Even with today's technological advances, the level of pollution is even worse.

Qi Zheng pouted: "Could it be that I said that I am not sure, so I can quit?"

Yue Jianping smiled "hehe" and didn't answer.

Qi Zheng said casually, and then asked: "Has the pilot project been approved to start? ”

Yue Jianping nodded hurriedly: "It has been approved, the funds have been allocated, and Jiagu can start governance." ”

Yue Jianping has not been idle these days, he has been supervising and running between the governance project site and the government non-stop.

The pilot includes the treatment of contaminated farmland, which not only involves a large number of stakeholders, but also requires the cooperation and effective connection of various stakeholders.

Prior to the project, the team organized a multidisciplinary group of researchers, including experts in environmental, psychological and sociological studies, to conduct a series of surveys in the area, and conducted a detailed analysis of local farmers' perceptions of pollution and the changes in farmers' land use over the decades. This governance can be said to be planned and then moved.

After analysis, the leading group divided the cultivated land in Hunan Province into key protection areas, safe use areas and strict control areas. The first two are safe and reliable main grain producing areas, and the strict control areas are governed by adjusting the varieties of planting items, which is the main battlefield of Jiagu.

Of course, there are quite a few experts who are not optimistic about this.

Professor Dai, a consulting expert of the leading group, was also at the scene, and he heard the confidence hidden in Qi Zheng's words, and he was quite disapproving: "Qi Jiagu should still think more about the governance plan, you know, price factors, efficiency, etc. are great challenges......

Yue Jianping said: "Professor Dai also led a team in charge of a pilot project for the remediation of contaminated soil in Hunan Province, which lasted for nearly four years and restored nearly 20 acres of contaminated land. So he's quite experienced......"

Professor Dai's team is also facing the problem of how to treat it.

Changing the soil is the easiest, but there are so many polluted plots in the country, where to pile up the polluted soil, and where to find new soil to fill?

Bioremediation is still in the laboratory stage and is neither suitable for large-scale promotion nor cheap. According to Professor Dai's calculations, even if the plants are cheaper, the restoration cost per mu will be tens of thousands of yuan per year, and it will take several years of continuous planting, and the total investment can be imagined.

Therefore, Professor Dai's team mainly adopts chemical remediation. That is, the use of chemicals to change the composition of the soil, or reduce the activity of heavy metals in the soil, so that it no longer migrates.

After treatment, the heavy metal contaminated soil was restored to the expected target, but the process was not easy: the remediation cost of nearly 500,000 yuan per mu and the remediation method were not too popular...... Perhaps the biggest takeaway is a warning to people about how costly it will be to reclean the soil once it is contaminated.

According to Professor Dai's governance method, this pilot will cost at least 2.5 billion yuan to implement. Therefore, its solution was eliminated in the face of Jiagu's phytoremediation technology.

But Professor Dai was neither convinced nor convinced by Jiagu's boasted super-rich plants.

Qi Zheng didn't bother to explain this. Anyway, facts speak louder than words.

The Jiagu soil treatment team led by Liu Xu drove into the pilot area and carried out phytoremediation with ease.

This time, "Golden Ramie No. 1" was used as the main force, but because the types of heavy metal pollution were more complex, the interplanting of southeast sedum was also carried out.

The mutated "Golden Ramie No. 1" is indeed a magical plant, without the mutagenesis of the "Nine Turns Nirvana Array", how can such an excellent super-enriched plant come from?

Although it only adsorbs cadmium metal, its roots can also transform other heavy metals into chemically inactive forms, preventing them from migrating and spreading in the environment, which is equivalent to integrating bioremediation and chemical remediation.

Under Qi Zheng's induction, the roots of "Golden Ramie No. 1" emitted a special frequency, cadmium was "attracted" and "swallowed", and other free heavy metal elements were "fixed" or adsorbed by the southeast sedum.

The higher the content of heavy metals in the soil, the higher the removal efficiency.

Each ramie plant can be said to be equivalent to a small function of the simpler "six gold and six building arrays", don't you say magical?

Qi Zheng doesn't need to do more, as long as he ensures his growth rate.

"Green Bamboo Hundred Soul Array (Second Order) trigger, main wood system, range: one hundred kilometers away. Effect: Moisturizes, grows. The creature is in the array, as if it was newborn, raising purple flowers, and growing vigorously. ”

The application of sufficient organic fertilizer nutrients, coupled with the moisturization of the spirit array, made the root system of ramie and southeast sedum develop particularly rapidly, and the "greed" of its "gold absorption" simply made Professor Dai look straight.

Witnessing the curve of soil metal content plummeting as plants grow, Professor Dai was frightened, this is too fierce, isn't it?

At this rate, at most three years, this land that is heavily polluted by heavy metals, which is a headache for everyone, will basically return to normal?

The most important thing is that this will not only not destroy the soil fertility, look at the situation of Jiagu vigorously applying organic fertilizer, and even fertilize the land; and then calculate the economic benefits of ramie, the investment is not large.

Where did Jiagu get these two varieties?

Remembering that he had been forced to remove heavy metals from the soil one by one, and then looked at the super-rich plants in front of him, Professor Dai almost burst into tears.

"I suggest that Jiagu's phytoremediation technology be included in the Ministry of Science and Technology's Science and Technology Benefiting the People Program Achievement Database, and vigorously promote it in the mining areas and industrial polluted areas of Hunan Province!" Professor Dai did not hesitate to change his stance and solemnly suggested to the Xiangjiang River Basin Management Group.

The progress of the Jiagu heavy metal treatment project exceeded the expectations of the leading group, and also made the local governments of Hunan Province rejoice.

For a while, the invitation for investment inspection floated to Jiagu Group like snowflakes, and the support of the same preferential policies as state-owned enterprises given in the grain production base and processing plant was used as a breakthrough to attract Jiagu to invest in the landing.

Wang Yuye enthusiastically arranged personnel to inspect and respond, while Qi Zheng was busy...... Open hanging.

Now that it has made plans to enter Hunan Province, it is the vision and demand of Jiagu itself to get rid of the haze of heavy metal pollution.

More than 50% of the farmland in Hunan Province is polluted by heavy metals, and more of it is actually lightly polluted.

But compared to the heavily polluted areas that can be centrally treated, these mild pollution are even more of a headache.

First of all, trace amounts of heavy metals can pollute food, which is both hidden and large, but the efficiency of treatment is very low. In addition, as one of the major grain-producing provinces, the pressure on grain production is high, and it is impossible to be idle for a long time.

Therefore, normally speaking, the treatment of mildly polluted farmland is beyond imagination and is impossible in a short period of time.

However, someone in Qi is never "reasonable".

"Six gold and six building arrays (fourth order) trigger, the main gold and earth two systems, range: a radius of 1,000 kilometers. Effect: Condensation, Ore Accumulation. It can condense the earth's veins and produce gold and silver. ”

Heavily polluted land is centrally treated, while lightly polluted farmland is "purified" unconsciously.

The two-pronged approach to "absorb gold" dares to call Hunan Province a new place!

Heavy metal elements such as cadmium, chromium, manganese, and zinc in the lightly polluted cultivated land in Hunan Province are divided into categories under the condensation of the spirit array, and the dust returns to the dust and returns to the mining area, and the destination directly refers to several non-ferrous metal mining areas of Tianhua Mining in Hunan Province!
