Chapter 173: Chapter 173: Pollution Control

From Aslan's words, Elijah heard Aslan's attitude and determination towards environmental protection.

The first pollution created by the cities of the human race is water resources, and then the burning of forests due to the desire for land. After that, the fertility of the land gradually declines under years of cultivation, and finally reaches the Merlot area. Then, as time goes by, It will be completely reduced to a desert.

Yi Laiya did not find this kind of situation in the Merlot area, especially the bud fruit trees and plum poplar cassava, which did not destroy the fertility of the land, but solidified the soil quality and gradually improved the surrounding environment.

In particular, Aslan and the others produced something called chemical fertilizer, which improved the fertility of the land very significantly. It is said that there is already a farm that is using chemical fertilizer to transform the land on a large scale.

"You're here!" Aslan didn't look back, just the wisp of fragrance let Aslan know the identity of the visitor.

Elijah nodded, and Kangcas and the others were shocked at first when they saw Eliya with a beautiful face, and then bowed their heads obediently.

"Landmallock is sorry for your trouble."

Hearing Aslan's words, Elijah couldn't help frowning.

She had hidden her strength for most of her life, but it was completely exposed because of this time.

Because before he left, Aslan handed Lanmalok to her and pointed out her hidden strength.

This was the first task Aslan gave her, and she had to do her best to complete it.

"You're welcome, after all, you've helped us a lot." Elijah spoke from the bottom of her heart.

At least today's elves and half-elves have slowly integrated into the life of Melo Town.

"That's great, I just need your help with something." Aslan said bluntly.

Elijah really wants to say, you really think of me as a free worker.

"The human race's damage to the environment is rooted in water resources, followed by land, and then the sky." Aslan said unhurriedly.

Elijah nodded in agreement.

As for the sky, it is actually atmospheric pollution.

"If we want to change all this, we must work together. I know that you elves have a lot of magic to change the environment, and I have also researched a lot of magic technology to improve the environment. As long as we join forces, we can create a perfect environment for humans and elves. Paradise of coexistence." Aslan began to draw a big cake.

Elijah also listened attentively, and her eyes couldn't help showing longing.

"What are you going to do?" Elijah quickly calmed down and said with a smile.

The magic of transforming the environment is not difficult. In fact, many human magicians have also developed that kind of magic, but most of them play it as tricks, mainly for transforming their own living environment.

Therefore, the leakage of environment modification magic will not have much impact on the elves.

Moreover, the environment can be transformed successfully, and the natural might can slowly recover. For their elves, there are only advantages and no disadvantages.

"Land reconstruction is already in the experimental stage. I hope you can spare time to pay attention to it. Sewage treatment is the main problem now. The sewage produced by hundreds of thousands of people every day cannot be underestimated. A little carelessness will destroy the surrounding area of ​​Merlot Town. The existing environment." Aslan said with a serious face.

"What about the sewage treatment plant you mentioned?" Elijah asked curiously.

"The domestic sewage in the entire town of Merlo will be discharged from the sewer to the sewage treatment plant, and then the sewage will be treated through several processes. I divide the sewage treatment into three levels."

"Primary treatment: I call it physical treatment, through mechanical treatment, such as grills, sedimentation or air flotation, to remove stones, sand and stones, fats, grease, etc. contained in sewage."

"Secondary treatment: magic element treatment, pollutants in sewage are degraded and transformed into sludge under the action of microorganisms."

"Third level treatment: advanced treatment of sewage, which includes the removal of nutrients and the disinfection and purification of sewage through light magic."

Elijah's eyes brightened when he heard this, and the trick came down again, and the originally filthy water could be recycled again.

After all, Sino Continent doesn't have so many chemicals, and a lot of sewage can be used without tertiary treatment.

"Then what do you need me to do?" Elijah asked urgently.

"Help me plan the sewage treatment plant, and at the same time supervise the environmental pollution in the Melo area. Any large-scale environmental pollution must be severely cracked down." Aslan said firmly.

Elijah glanced at Aslan, and said slowly, "Then how do you deal with the pollution in several industrial areas?"

Aslan was speechless after asking a single sentence.

It is absolutely impossible for the cement plant and steel plant to stop production, which is related to the rapid development of Melo Town in the future.

"I will install waste gas pollution treatment equipment at the steel plant as soon as possible?"

This did not embarrass Aslan, because in his previous life he teamed up with an elf tribe to restore the environment in the Melo region to a standard suitable for elves to live in, and at that time developed a lot of pollution treatment equipment.

The biggest pollution in the iron and steel plant is the waste gas emitted by the huge chimneys every day. Because the scale of the iron and steel plant is still small, Aslan doesn't care too much. Since Elijah raised it, he will show his determination to prove it. show him.

"I discovered a special material two years ago, which I call activated carbon. The activated carbon is made into a huge adsorption device, and the exhaust fan sends the organic waste gas into the adsorption device. The organic waste gas is absorbed by the activated carbon device in the adsorption device. The gas is purified, and the purified gas is discharged to the atmosphere to complete the purification process." Aslan said confidently.

Elijah was in a state of stupor.

Everything that Aslan said today contains more knowledge than those of the elves who have studied the protection of the environment for thousands of years, or even longer.

"Are you really a human race?" Elijah asked subconsciously.

"Of course, it's just that I am a human being who loves nature." Aslan laughed loudly.

Elijah also looked at Aslan with a smile, and there was a different look in her eyes.

"I will establish a Ministry of Environmental Sanitation as soon as possible. You will be the Consul of Environmental Sanitation, responsible for the environmental sanitation of the whole territory, and you will recruit all the personnel yourself." Aslan said.

Elijah nodded.

"Then I'll go back and make plans, and I'll hand it over to you in two days, or three days."

Aslan nodded, and Elijah left like a lightning bolt.

Concas hesitated to speak, only Kruse and the others took it for granted.

After a while, a group of tall men in heavy armor came.

Just at the first glance, Concas couldn't take his eyes off.

He had long heard that Lord Merlot subdued a group of barbarians, and now it seemed to be true. Looking at the terrifying armor on their bodies, it must be at least one or two hundred catties!

There is no manuscript saved, and now it is distributed on the spot, and the holiday will be in a few days. Please continue to support the brothers, and don't stop recommending tickets and subscriptions.

There will be one more later.
