The use of plants as a pollutant clean-up, that is in the eighties and nineties of the twentieth century, only developed a new means of pollution prevention and control, compared with the traditional chemical methods, plants have the advantages of low input, good effect, and not easy to cause secondary pollution.

Even in the 21st century, microbial treatment methods for water pollution began to appear, using some genetically modified microorganisms to adsorb pollutants in the ocean or water, this kind of field, involving biomanufacturing and genetics, the field of genes, which is far from Zhao Xin can get involved now.

But some simple ones are still okay, such as oleanders.

Speaking of which, this plant, which is more common in later generations, has always been known for its toxicity, and its leaves, neck, and fruits all contain poisons, and after taking a certain dose, it will produce a violent toxic reaction.

Ordinary people only know this, about the other functions of oleander, or once, in the archaeological special tourism only discovered.

Northeast China is the birthplace of Hongshan culture, similar archaeological excavations organized by Peking University many times, sometimes, in the interval between the two times, there will be a certain amount of time to rest, for the old professors, maybe choose to rest in the hotel, Zhao Xin of course will not be like this, along with the travel around.

The most famous in the Northeast is the old industrial base, the pain of the late 20th century, so that the Northeast has suffered a huge blow, and the family living in the factory all his life has suddenly fallen into a desperate situation, which is a huge blow to the entire Northeast.

In the 21st century, with the recovery of the Northeast base, coupled with the development of many aspects, some abandoned factories have either become creative industry parks, or become a scenic spot, Zhao Xin has been fortunate to visit several industrial bases, and some of his layouts for steel mills, nine out of ten, are in these visits, than the product of the gourd painting scoop.

As for the role of oleander in pollution control, it is obtained from visiting these industrial bases, of course, these are some factories with new ideas.

Whether it is a steel plant or a cement plant, it is an enterprise with high energy consumption and high pollution, especially cement pollution.

Cement itself is a source of pollution, in order to ensure the effect of cement, cement must be ground very finely, the large clinker is crushed, which itself will produce dust, once the cement powder flies into the air, it is not easy to degrade particulate matter, which is a natural source of pollution, can not be avoided.

Even after a large number of protective measures, for example, to strengthen environmental governance, in the crushing workshop, at least after several protections, to avoid a large amount of dust, is discharged into the air without treatment, for example, around the processing workshop, there is a large area of plants and various sedimentation zones, for example, there are a series of physical and chemical methods.

Oleander in later generations, in some polluting factories in a large number of planting, because of the characteristics of the plant, oleander for sulfur dioxide, carbon dioxide, hydrogen sulfide and other toxic and harmful gases, has a lot of adsorption effect, the same, because of the relationship between leaves, it also has a relatively strong adsorption effect on suspended solids in the air.

Of course, the leaves of oleander are a little worse than some specialized adsorption plants, but in terms of growth, popularity, and comprehensiveness, oleander is the key, so to speak, it is a natural anti-pollution plant.

Oleander is a plant native to Iran, but it was introduced to China very early, and many poets of the Northern Song Dynasty have described oleander in their poems.

When Zhao Xin decided to plant a large number of oleanders in the factory, he did a similar survey to find oleanders as much as possible.

Unlike the cultivation of seeds in this era, Zhao Xin knows that most plants can be cultivated by cuttings, and during the growth period, it is enough to avoid strong light.

After finding some specialized growers, for example, people with special knowledge of plants and flowers, it was popularized on a large scale.

Plants, as long as they meet the growth habits, can be planted on a large scale, when the oleander grows successfully, and continues to form a grove, this has also become a unique scenery in the factory.

No one knew that this thing, which was forcibly ordered by Zhao Xin and planted here, actually contained such a great effect, it was easy to deal with sewage and solid pollution, but gas was the most difficult to treat.

Non-degradable particulate matter has become an important indicator of air quality in later generations, and in this era when there is no testing method, it can only be treated by various methods as much as possible.

Zhao Xin can not understand the principle of oleander decontamination, let alone ignore the complex knowledge of chemistry and biology, he only needs to know that black cats and white cats, catching mice is a good cat.

In later generations, some heavily polluting enterprises planted oleanders in large quantities, which were chemical and complex in all aspects.

Ding Haijun also has some polluting enterprises, but they are ironworks and cement factories, and the others, even if they exist, are very few, as long as they are strengthened, they will be fine.

In the middle, the most important thing is the cement plant, even if the plant is set up indoors as much as possible, the natural inherent pollution will still be blown away to the surroundings with the wind, layer by layer of windbreaks, isolation belts, along with oleanders, is to play the role of adsorption, so that they can be adsorbed to the plants as much as possible, rather than falling on the ground, in order to strengthen his adsorption capacity, regularly cleaned.

This cleaning is very simple, that is, with a water wheel, with some tools, to clean the oleander leaves to reduce the floating dust on it.

This is a simple method, oleander for the adsorption of dust, is the natural reaction of the leaves, when the leaves, after accumulating enough dust, it will affect the absorption, so that even for the growth of oleander is not good, clean up regularly, clean up the dust, avoid secondary pollution caused by strong winds or other reasons, and can also increase the adsorption rate of oleander for particles in the middle of the air.

However, this move, in this era, makes many people not understand, an ordinary plant, still to clean up, some larger areas, and even a considerable amount of manpower is specially arranged to do this thing.

This cleaning plants, daily plant cleaning, indoor and outdoor cleaning, these systems together, is very critical for the entire cement plant, in the traditional time, the cement plant full of dust everywhere, has become clean and tidy, dust pollution, is also limited to a fairly close range, the effect is very good.

Iron and steel plant, the main pollutant, is the exhaust gas produced by combustion, among them, there is coal combustion exhaust gas, there is also calcined steel, the emission of harmful gases, for these, there is no more convenient way, oleander can absorb harmful nitrogen, sulfur dioxide and the like, but the effect is not good.

That can only be through experiments, for example, not direct emissions, the exhaust gas through some chemical pools, solidification and reaction, so as to reduce emissions, at the same time, combustion can also choose better methods, for example, the establishment of the combustion chamber, the addition of oxygen, and other methods, so as to ensure the complete combustion of coal as much as possible, reduce the exhaust gas consumption caused by incomplete combustion.

While Zhao Xin was worried about production, he also put a lot of effort into these exhaust gases and pollution, which made many Ding Haijun's management very incomprehensible.

However, Zhao Xin has always insisted on doing it, and even when the safety of production was promoted to a considerable status, he still did not relax the control of pollution.

These methods will greatly increase the cost, a large number of oleanders, the cost rise is not high, but also a one-time investment, once the line, as long as regular maintenance is good.

It is not the same as ordinary green plants, oleander can bloom, oleander has a variety of flower colors, and the appearance is also very beautiful.

In the control of pollution, the use of labor is increasing, even if there is plant treatment, most of the work, still need people to complete, taking the cement plant as an example, simply used for pollution above the personnel, almost occupy more than one percent of the cement plant, these do not produce, but need heavy labor workers,

These people who are cleaned up regularly, they are originally laborers, but they are not engaged in production, and this is a key problem.

Take the cement plant as an example, responsible for this work, as many as 80 people, you know, the cement plant is in addition to the steel plant, the largest factory, more than 80 people, is not enough, there are plans to expand recently.

For managers, front-line workers, let alone 80 more, even if it is 800 more, it doesn't matter, they are on the front line of production, they will directly generate profits, the more personnel, the more profits.

However, these people who are responsible for the sanitation and cleaning of the factory do not create value in themselves, and there are many expenses, some water trucks that transport water, and a lot of other tools, which need to be spent on a regular basis.

In fact, the largest expenditure is still in labor, which is no longer in the production line, and is also included in the overall wage standard, that is to say, every month, these people alone spend as much as 2,400 yuan on wages.

This money, compared with the monthly profit of the cement factory, is really a drop in the bucket, but these managers can't figure out why they do this, isn't this a net expenditure, in some people's minds, this part of the expenditure, can be completely subtracted.

Zhao Xin doesn't need to explain so much, in the Ding Navy, his authority is getting higher and higher, and the part of the labor force of the Ding Navy is part of the family members of the Xiang Army, and more is the victims of the Huainan and North Roads.

The common people of the Chinese nation are kind and grateful, and when they encounter a famine, they have to leave their hometowns and choose a way to live, and they are at a loss for the future.

If you leave your hometown, you will become a rootless wanderer, lucky, you will find a way to live, if you are unlucky, you may not even find a corpse.

At this moment of life and death decision, Zhao Xin appeared, not only giving them a real way to live, but also allowing them to live a good life.

In the official face, Zhao Xin is their master, Ding Haijun's festival envoy, these people's life and death are all controlled by him, in terms of feelings, Zhao Xin is a bodhisattva who gave them a way to live, I don't know how many people, Zhao Xin's tablet was offered at home, and incense was prayed every day.

In this case, not to mention that there is some truth in this, even if it is unreasonable, no one dares to disobey Zhao Xin's order.

Pollution control, even in the 21st century, there are people knowingly committing things, in this era that has not yet realized what pollution is, no one cares, but Zhao Xin cares.

He may not deliberately explain it to the management, but he will also mention it, and even at some middle and high-level factory director meetings, he will talk about the disadvantages of pollution.

The benefits of industrialization they have to see and enjoy, but these disadvantages, they must consider, and as far as possible, do not leave them to future generations.

Moreover, the increase in costs has not affected the overall profit, which has been strictly calculated by Zhao Xin.

For example, in the case of cement, the cost of cement has increased by at least 30% compared to the absence of measures to prevent pollution.

30% is really not a small number, when converted to the huge production capacity of Ding Haijun's cement and steel, it is an astronomical figure, but Zhao Xin is still willing to implement it, the reason is the high profit.

In the 21st century, not to mention 30% of the profit, sometimes, one or two points of profit is a key to determining the life and death of the enterprise.

There is a joke not to say, the same aunt who sells breakfast, one often asks if he wants tea eggs, one often asks whether he wants one tea egg or two, and in the end the latter survived, relying on the profits brought by hundreds of tea eggs a day, don't underestimate it, hundreds of tea eggs, maybe there are seventy or eighty yuan of profits, for a small business catering, this has decided life and death.

Industrialized factories, even more so, some low value-added, no technical content, low threshold industries, they are not a unique business, they need to face the premise of various regions, even global competition, 30% of the cost, enough to determine whether an enterprise can survive.

But in the Northern Song Dynasty, this thing is a unique business, to put it bluntly, the entire Northern Song Dynasty, and even the whole world, at present, only the navy has the ability to make cement, the price of cement, can be set very high, now, even if the cost of preventing pollution is increased by 30%, the final gross profit has reached more than 80%, which greatly protects the profit.

There are profits, and take into account the control of pollution, why not, under the premise of creating high profits, to ensure the green mountains and clear waters of the city, this is the real sustainable development.
