Before returning to the college entrance examination, I became popular in the science circle

"Our ultrafiltration membrane is awesome, and the amount of wastewater is only one thousandth!" It deserves the name of ultrafiltration. Such a superior filter membrane was born in front of his eyes. Although he only did some trivial auxiliary work, the same With honor.

"I dare say that this small filter membrane has an economic value of no less than [-] billion!"

As the most important element of human survival, no matter whether you are poor, rich or not, who doesn’t want to have a safe drink of water? Especially today when water pollution is becoming more and more serious and threatens the safety of human life, a safe drink of water is undoubtedly what many people dream of.

Some excellent water purification technologies on the market, such as reverse osmosis filter membranes, can also achieve the effect of filtering water, but the amount of wastewater can reach two-thirds, causing serious waste of water resources and making it uneconomical to use.The water purification equipment currently on the market has a low wastewater ratio.

And now, they have ultrafiltration purification membranes!

The amount of wastewater is less than one thousandth, and it is basically pollutants. The wastewater ratio is infinitely close to zero.The filtered water molecules are fast and clean, and the production cost is not very expensive. If a water purifier equipped with such a purification membrane is released, it will definitely cause a sensation and rush around the world.

Even Ruan Chengxu, who has a broader vision, has already thought of a larger section, seawater filtration. Using this as a seawater filter, China will no longer worry about the depletion of water resources, and the water shortage in the west will be able to get a complete solution.

Wu Tong, this is the development of a golden hen that can lay golden eggs, and even another treasure with extremely economic and strategic value.

"The ultrafiltration membrane is temporarily successful, but we still have an urgent point to solve!" Compared with Ruan Chengxu's excitement, Wu Tong seemed calm.After all, she had predicted such an outcome, and now she had just achieved it.

She was also happy that the prediction had come true, but she was more focused on another issue than her excitement.Wu Tong glanced at the cup of slightly turbid liquid, "How to deal with this part of the pollutants is the top priority!"

After all, the numerous heavy metal residues inside, as small as a speck in front of them, looked harmless.However, large-scale utilization and the collective accumulation of so many concentrated pollutants are still a major hazard. A bad thing is that they do not create miracles, but become sinners that aggravate environmental pollution.

Speaking of the issue of pollutant treatment, Ruan Chengxu could not help but fall silent from his excitement.

If pollutants were so easy to solve, the world's pollution problem would not become increasingly serious.So far, they do not have an effective way to control pollution, which is a headache for the world.

Without a treatment plan, such an excellent ultrafiltration purification membrane cannot be promoted and used?Wouldn't that be such a shame?
In other words, Wu Tong has a solution?Ruan Chengxu looked at Wu Tong expectantly. If anyone could create a miracle, in Ruan Chengxu's heart, it must be Wu Tong.

Wu Tong developed and manufactured ultrafiltration purification membranes. Did he anticipate the current situation?

"Brother Xu, you think too highly of me. I only have some ideas for the specific plan now, and it's not perfect yet. I still need time to perfect it. I will collect these experimental data first, and I will continue to study and deduce it!" Wu Tong laughed. She really wasn't. Treasure bag, whatever you want is available.However, facing this problem, she is not untouchable.

It's a problem, and there will be a solution. It's just the direction of the solution that needs to be found.

As a solution for organic pollutants and inorganic pollutants, Wu Tong thought of N18, which has super decomposition capabilities. This part is no longer a problem for her.After making the distinction clear, the most important thing that needs to be solved now is actually what she has been considering, heavy metal pollution.These heavy metals are harmful to the human body in excess amounts.

But for modern society, they are also indispensable metal resources, and many of them are even scarce resources.How can these heavy metals be extracted so that they no longer become harmful pollutants, but transformed into effective resources for recycling?

After collecting the data, Wu Tong returned to the office and fell into deep thought.In his mind, various directions of speculation and information related to pollution processing were flying.

Wu Tong even thought of the virtual items in novels he had read before.This was a plant creation novel she had read in her previous life. It was said that the protagonist refined a special seed.

This kind of special seed, when planted in water, will naturally absorb heavy metals in the filtered water and grow into different-colored lotus flowers. These different-colored lotus petals are the metal substances they absorb.

There are also science fiction-oriented ones, such as the magical polymer smart filter, which can intelligently filter harmful substances and restore the water to a clean and pollution-free state.

···Human beings have unlimited imagination, although many times, there is no theoretical basis, and most of them make people laugh.However, this is also a beautiful idea that many people have for purifying the environment.

Wu Tong now also wants to design a material, or a set of process plans, that can achieve the effect of special plant seeds similar to the author's imagination, which can effectively extract and separate pollutants in polluted water, and can be classified and processed into Effective resources.

After several deductions, various ideas collided in my mind. After being proved by Goldbach's conjecture, the energy efficiency was once again improved. Absolute deduction, absolute direction combined with sublimated absolute deduction, worked at full speed.

A vague direction appeared in Wu Tong's mind. She picked up a pen and wrote down the four words "reduction" and "adsorption" on the draft paper at hand.

With these two indicative general directions, Wu Tong began to deduce, how to restore it, and what substances can react with all or most metals?
acid?Reacts with acids to form various sulfuric acid compounds?oxygen?React with oxygen to form various oxides?Part of the salt?
Adsorption?What kind of adsorption capacity is most effective?graphite?This is a mineral composed of carbon element. It has good electrical conductivity and can quickly absorb precious metals such as gold and silver under certain conditions.

Clay?The surface charge has special interest. Through the adsorption mechanism, it can quickly absorb precious metals such as gold and silver.

Activated carbon?The special pore structure and surface charge also allow it to quickly absorb precious metals.

However, the absorption efficiency of these fast gold-absorbing materials is not stable and is affected by many factors. They do not have the energy efficiency to completely absorb metal pollutants.And if it is combined with other substances after the previous reduction reaction, these substances are likely to lose their effectiveness.

Speaking of adsorption, there is another thing that comes to mind immediately.

magnet?What can be attracted is iron, cobalt, nickel and their alloy materials. The reason is that the atomic internal structure of these materials is relatively special and they have magnetic moments themselves! (End of chapter)
