Beibei roams the magical starry world

Humans have been dumping garbage and discharging sewage into the Pacific Ocean for decades. The most famous gathering place of marine garbage is the Pacific Garbage Patch. The area extended for about 1950 kilometers from 2010 to and was about kilometers wide. This means that the garbage in this garbage patch covers three countries of France. The large amount of plastic waste in the garbage patch has caused great harm to the marine ecosystem and human health.

A certain country discharged nuclear wastewater 3,000 nautical miles away from its Fukushima nuclear power plant near the North Equator. It will spread to most areas of the Pacific Ocean within fifty-seven days after the discharge. This means that nuclear sewage will affect the entire marine ecological environment and bring indelible disasters to humans and the earth, so it is even more harmful.

At this time, Beibei and his friends were standing in the aircraft over the sea, looking at the dark green seawater.

Beibei said: "Xiao Cong, you are the commander-in-chief now, we follow your arrangements."

"The construction of the purification zone this time involves physics, chemistry, space and other knowledge. I must learn and participate." After coming to Earth, Jack, who wanted to become a science and technology god, said.

"In order to save the earth, I also want to participate." Xiaobai said

"Everyone is deploying sensors, jammers and vortexers in this sea area." Robot Xiao Cong said as he used a pen to draw a red inner circle with a red pen on the Pacific Ocean map, and then drew a big circle with a yellow pen. Yellow outer ring.

The robot Xiao Cong took out ten metal beetles and said: "This is a deep sea sensor. One is placed every 120 nautical miles along the red circle. It can sense radio waves, sound waves and light waves close to the yellow circle."

Robot Xiao Cong asked: "Who will release it?"

"I'll go." Jack rushed to say, singing a children's song at the same time

"Little eagle, little eagle

I am a happy little eagle

Fly over the mountains, fly over the woods

I am a flying little eagle.”

I saw Jack turned into a little eagle, stretched out his two talons, grabbed ten beetle sensors and flew away.

"Remember to be fixed on the bottom of the sea." Robot Xiao Cong reminded

Everyone found it interesting watching Jack fly away, and looked at the robot Xiao Cong, as if to say: "Is there anything else? We have to install the equipment."

The robot Xiao Cong took out twenty more metal conches and said: "This is a deep-sea jammer. It can spray haze and send out chaotic waves to interfere with the signal systems of all devices. Along the yellow circle, place one every one hundred nautical miles. Taiwan. Who is going?"

"I go"

"I go"

"I said it first, I'll go"

"I said it before you, but my voice was a little softer. I'll go."

The friends are all rushing to go.

Robot Xiao Cong took out another forty metal Yin-Yang fish and said: "This is a deep-sea vortexer. It can create vortices and airflows from level three to level twelve in the deep sea. All objects below 10,000 meters above the sea surface will be involved. On the bottom of the sea, along the yellow circle, place one every fifty nautical miles. Each of you takes two conches and four yin-yang fish and go and place them!"

Just then Jack came back out of breath and said: "Is there anything else? I haven't exercised for a long time, I'm a little out of breath!"

The friends looked at the panting little eagle, picked up the equipment and rushed away, going to set up their own arrangements.

After making Jack stunned for a while, the robot Xiao Cong told Jack again, then mounted the wild goose and flew away.

Jack also grabbed six pieces of equipment and flew them to the yellow circle and placed them.

After a while, everyone came back and talked happily about the joy of flying on the sea.

The robot Xiao Cong turned on the control system, and light spots appeared on the screen one by one. After inspection, everything was perfect.

Robot Xiao Cong said: "After inspection, the equipment has been put in place, and everyone has done a perfect job. The next step is to arrange the filtration and refining system, which is what we call the purification area."

The robot Xiao Cong took out pieces of fishing net-like things and said: "This is a nano filter, which is mainly used for filtration, sedimentation, acid-base adjustment, etc. to remove suspended solids and large particulate matter in sewage and adjust the pH of the solution. Each net is spread out for one hundred nautical miles, and this is the first step of pre-processing we mentioned earlier, one net per person, laid along the red circle."

The friends each took a net and thought: "It turns out that it keeps the garbage out and puts in radioactive elements such as tritium, strontium, cobalt, uranium, plutonium, cesium, and iodine."

After the friends laid the net, they flew back one after another.

After checking, the robot Xiao Cong confirmed that the net has been laid.

Robot Xiao Cong said: "Let's go."

After saying that, the robot Xiao Cong rode the wild goose and flew towards the center of the red circle.

The friends were stunned for a moment and then flew over.

As we were approaching the center, we saw a mountain-like building in front of us.

"What is that! Standing on the Pacific Ocean, it's so majestic!" Dantan sighed.

Soon the friends arrived at the top of the high-rise building, and saw that the platform at the top of the high-rise building was as big as twenty football fields, and it was filled with robotic big-headed fish.

The friends looked at Xiao Cong curiously and waited for the explanation.

Robot Xiao Cong said: "This is our purification base. The stomachs of these robotic big-headed fishes contain organic phases such as tributyl phosphate or amide. They swim in polluted water, swallow sewage into their stomachs, and leave radioactive elements in their stomachs. , the separated sewage is spit out. This is the second step of multiple extraction."

"Look if there is an open door under the water." Robot Xiao Cong pointed to the water.

The friends hadn’t noticed it before but now they saw it, a hole as big as two football fields.

"The belly of the robotic big-head fish is filled with a mixture of radioactive elements and tributyl phosphate or amide. The mixture is called the 'organic phase'. After it is full, it swims back and spits the 'organic phase' into clean water. The radioactive elements It will be integrated into the clean water. This is the third step of back-extraction. At the same time, the bighead fish that swims back needs to be filled with new organic phases such as tributyl phosphate or amide." After the robot Xiao Cong finished speaking, he took his friends to sit on the Elevator, the elevator goes down to the underwater second floor of the building.

"Look, this transparent pool is like a marine aquarium. Inside is a mixture of the organic phase spit out by the robot fish and clean water, which is the 'back-extraction'. Let's go down two floors." Xiao Cong, the robot, led everyone. Go down two floors along the spiral staircase.

The friends murmured inwardly, "It's not like walking down two floors, but walking up to the 20th floor of an ordinary high-rise building. This robot is so unreliable."

The friends walked for more than an hour and arrived at the fourth floor underwater. In front of them were silver-white metal plates. The water on the second and third floors passed through these metal plates.

"This is the fourth step of electrodeposition. The second and third layers of strip water are electrolyzed, and the radioactive elements will be gradually deposited on the cathode. That is, these metal plates, these metal plates are stainless steel, titanium or nickel, etc. Any material can be used to make a cathode." Xiao Cong, the robot, explained.

"Let's continue going down one level." Robot Xiao Cong said

"No, let's take the elevator!" Beibei quickly stopped him.

So, the friends took the elevator to the fifth floor underwater, and saw the water flowing down from the fourth floor passing through the sticky stuff.

"This is the fifth step of ion exchange. The radioactive elements in the four layers of water are not stuck to the cathode plate. When they flow here, they are adsorbed by the ion exchange resin." Xiao Cong, the robot, explained.

"Let's go to the next floor and see what happens to those cathode plates," said the robot Xiao Cong.

The friends came to the sixth floor and saw through the glass that the cathode plate inside was burning.

"This is the sixth step of concentration and purification: the radioactive elements deposited on the cathode are concentrated and purified through burning, dissolution, reprecipitation, etc. You can see below the decomposed element loading container."

When the friends came to the seventh floor, they saw many snake-like tubes swimming among the plankton and algae, sucking the gray liquid spit out by these creatures.

"After refining these liquids, the viscous substances produced can be processed into the most precious coating agent. We will test the purification area system tomorrow." Xiao Cong, the robot, said.
