In some quiet and unique corners of the world, the Lord of All Things has created some precious and magical water sources, which are as transparent as diamonds in color and outstanding in quality.

Nankai City in Min Province, the place where Jiagu was born, was not among them.

But I don't know when it began, not only the environmental scenery in Nankai City is top-notch, but the water quality is also at the top level in China and even in the world.

Isn't this normal in the eyes of outsiders? The water quality of an area can reflect the local ecological level in a concentrated manner, and the water source of the land where Xianming rice can be grown must also be convincing.

Ten years ago, the ecological scenery of Nankai City was not bad, but the water source was really high-quality. At that time, agricultural pollution, industrial pollution, and even domestic sewage all had a great impact on the quality of water sources in the territory. In some places, the water source is even more polluted.

In order to learn from the water, Nankai City has also used the method of combining source pollution control and water environment remediation, from the local to the whole city, and persisted for more than ten years to have today's "diamond water source" with evergreen water quality.

Among them, I dare not say that it is all the credit of Jiagu Group, but Jiagu can indeed say with confidence that without Jiagu, the water source of Nankai City will definitely not have the purity it is now.

At the mouth of the confluence of the tributaries of the Minjiang River in Nankai City, Li Fan, head of the "Water Environment Biopurification" Research Institute of Qi Zhenghe Laboratory, is witnessing a group of green "visitors" - evergreen aquatic iris, aquatic canna, calamus, goldfish algae, etc., with the help of Jiagu staff, these plants with water purification function either sink to the bottom of the water or are planted on the river beach.

"This month, the city has just carried out water quality monitoring, and most of the rivers have outstanding performance in key indicators such as ammonia nitrogen content, dissolved oxygen content, and transparency, and the average water quality has reached Class II. This section of the river is considered to be a poor performer. Li Fan said with a smile on his face.

Of course, the "poor" in his mouth is not bad anywhere.

Qi Zheng took a natural look and asked, "This is your latest achievement?"

Li Fan pushed the glasses that looked like the bottom of the wine bottle, and said calmly: "It should be said that only super canna and evergreen aquatic iris are the latest achievements, and the others are not new." ”

"Aquatic iris?"

"Oh, an evergreen aquatic herb, made of hexagonal fruit iris, tall iris, short-stemmed iris and other hybrids, the hybrid original species from the United States, Russia and other high latitudes, because of its strong cold resistance, can make up for the lack of evergreen aquatic plants in the middle and lower reaches of the Yangtze River in winter. ”

"What about the advantages?"

"We amplify its vigorous metabolism and can effectively absorb, accumulate, and decompose nutrients and a variety of organic pollutants in wastewater even in the middle of winter......"

"Where's the canna?"

"Super Canna has a 70% removal rate of harmful heavy metals such as lead, mercury and cadmium in the aquatic environment, and this section of the river is navigable, and it has been detected that it is susceptible to heavy metal pollution......"

From Li Fan's introduction, we can know that there are certain "routines" for aquatic environment, especially river management. Generally, it is necessary to cut off the external pollution of the river, that is, the shore pollution sources around the river, so that their pollution will no longer affect the river; secondly, it is necessary to control and clean up the endogenous pollution of the river, such as removing the silt and impurities in the water at the bottom of the river; thirdly, to further purify the water quality of the river; and finally, to try to restore the ecosystem of the river, and strive to restore the original self-purification ability of the river.

The excellence of the lab-grown "super aquatic plants" is that they are almost the last two steps in place.

However, this kind of purification + ecological restoration does not mean that a variety of water purification plants can be planted densely in the water, if there is no reasonable matching, there are many water purification plants, but it is too much.

For example, the arrangement of water purification plants is to be layered, the upper layer is arranged with floating plants such as water lilies, which mainly play the role of beautifying the river landscape; the middle layer is arranged with water plants such as Zaili flower and calamus, which are rooted in the river, exposing the "head" and "body", which can not only intercept the sediment that may flow into the river on the bank, but also stabilize the water and soil, and even play a role in shielding the river from sunlight and cooling the river; the lower layer is arranged with submerged plants such as goldfish algae, which are lurking in the river and do not show their "heads" The main function is to compete with the algae in the water for nutrients, consume nutrients such as nitrogen, phosphorus, permanganate and other nutrients in the river, and inhibit the growth of algae that affects water quality, so as to improve water quality......

For example, in winter, these water purification plants stop growing, and some will rot in the water, and if they are not cut in time, the water will not be purified and the water will be muddy - for this reason, the laboratory has introduced the evergreen aquatic iris, a cold-tolerant aquatic plant, to improve.

There is a lack of systematic research on the effect of various aquatic plants on sewage treatment in China, and a large number of excellent aquatic plant resources adapted to growth have not been developed and utilized. Li Fan's work is to obtain a batch of water purification plants with good genetic traits, strong adaptability and strong purification ability through systematic screening and cultivation.

Of course, this kind of systematic research is maintained by burning money. Fortunately, with the blessing of the Spirit Array, they at least "burned" a batch of achievements.

Qi Zheng was a little more relaxed and asked: "If it is a more polluted water environment, can the water quality be improved in a relatively short period of time, such as ...... within half a year?"

Why is it that everyone knows about the benefits of bio-decontamination but doesn't invest in so much research?

Because the shackles of biological decontamination are even more. First of all, biological purification is a slow process, and the more urgent it is, the worse it is, and even under the premise of serious pollution, it is uncertain whether aquatic plants can grow normally, so how can we talk about "purification"?

Qi Zheng could use the Spirit Array bonus to play "extraordinary", but he wanted to know what step the laboratory's plan could go without him making a move.

Li Fan didn't stumble and said, "Yes." Through the selection of species, the collocation of communities, and the supermicrobes cultivated by the microbiology institute, we can give full play to the purification and application potential of super aquatic plants......"

Qi Zheng suddenly forgot that he could also apply it with the results of the Institute of Microbiology.

The Institute of Microbiology is undoubtedly one of the biggest "hills" in the Jiagu laboratory, and it is even said that no crop can be studied without microorganisms. On the contrary, in many cases, microbial breakthroughs can bring surprises to the breeding of new crop varieties, such as the super rhizobia to the revolutionary "Jiadou 13".

The same is true for water purification. After all, a major turning point in the history of water environmental protection, the basis of today's sewage treatment technology - activated sludge, in the final analysis, is a general term for bacteria, protozoa and algae and the organic and inorganic substances they are attached to.

"The Institute of Microbiology provides us with more powerful super strains and microbiota that can coexist with the microbial populations in the existing water treatment system, so that more than three kinds of microorganisms can coexist in an environment without encroaching on each other and multiply rapidly, and can degrade more kinds of pollutants, and their decomposed substances can be transformed or stored in the body by super aquatic plants," Li Fan said of the Institute ......of Microbiology, his tone was both envious and painful.

Because the Institute of Microbiology is in the Jiagu laboratory, it has abundant funds and remarkable results, and has always been the main focus of other project teams. What's more, if a project like theirs requires the cooperation of the Institute of Microbiology, it is not possible to rely on "the same family" to cooperate.

Thinking of the funds that were divided, Li Fan couldn't help but have a toothache.

Finally becoming the protagonist again, Li Fan also briefly mentioned the "auxiliary achievements" of the Institute of Microbiology, like a few treasures to publicize the research status of his dozens of "super aquatic purification plants".

Qi Zheng knew well that the project teams in the laboratory were "loving and killing each other" for funds, and after listening to Li Fan's report on the results, he nodded heavily and said: "Professor Li has worked hard, and it is not easy to get dozens of results at the same time." ”

This sentence made Li Fan's eyes red, nearly ten years of time, hundreds of millions of investments, not to mention that it is not easy.

Thankfully, at least the investment of the "financier" was not wasted, and it was much more comfortable to open his mouth to ask for funds later.

Li Fan's eating appearance is quite Sven: "We have cultivated a lot of super aquatic plants, but the research on their application is not thorough enough, and we still need continuous research." Didn't someone in the group suggest that we have some high-quality water and can sell it? I hope to build an annual and efficient aquatic plant purification and restoration system, so that there are high-quality water sources everywhere in China!"

Good guy, Li Fan's body looks thin, but his heart is quite big.

But even if he knew that he was "cheating" the funds, Qi Zheng could only nod.

The scope of water sources is too broad. No life can do without water, or any good life needs good water.

In order to produce high-quality agricultural products, high-quality water is inseparable, in order to produce healthy and safe food and beverages, high-quality water is inseparable, and human beings are also inseparable from high-quality water in order to live a long and healthy life...... If nothing else, if we could have the cleanest water source in the world, whether in lakes or rivers, like Finland, and even water that children can drink directly, national happiness can be raised to a higher level.

Qi Zheng knows this kind of truth, and Li Fan is afraid that he knows better.

I have to say that under the influence of Qi Zheng, Jiagu is more or less open-minded - if Li Fan is going for fame and fortune, just the research of dozens of "super aquatic creatures" is enough to become famous.

However, he wants to build a large-scale aquatic plant purification and restoration system, not to mention the difficulty and time required, just putting forward such an idea, in today's era of surging fame and fortune, is thankless.

At least, for Jiagu, it is definitely easier to "occupy" some high-quality water sources to sell mineral water than to "make high-quality water sources everywhere in the country".

Li Fan is another Jiagu man who fantasizes about changing the world.

However, looking at his current achievements, it is not impossible to change the world.

Maybe not as much has changed as expected, but it has changed in the end.

For this kind of challenge, the boss of Jiagu ...... Indulgence, of course.

Qi Zheng quickly decided: "If you have ambition, let's start by winning the sewage treatment and water quality improvement project in Hubei Province." ”
