Don't take this time and wait for when!

Xia Ying had no doubt that after a while, Zhou Xiao really let herself take a hundred samples from ten tons of garbage!

Mo Li looked at Zhou Xiao and whispered, "I'm going to bully the little girl again!" ”

Why is Zhou Xiao so wrong when she hears this?

Xia Ying has lived a good life since she was a child, and she has indeed never done dirty work, let alone rummaging things in the garbage heap.

Even with a mask, she almost threw up the overnight meal.

Xia Ying was wearing gloves and holding a clip in her hand.

She needed to get two pounds of trash out of a pile of garbage.

"Gross!"

The passing year is not good!

As soon as Xia Ying clamped down, she caught a soft thing, and when she opened her eyes, she saw a dead mouse that had been dead for no idea how long it had been dead, and her whole body had thinned.

A strong rancid smell came to my nose.

"Gross!"

couldn't help it, Xia Ying took off her mask and spit it out.

It's okay not to take off the mask, as soon as she takes off the mask, the rancid smell rushes directly from the mouth into her lungs, Xia Ying feels like she is going to suffocate!

A boy in the same major saw this and wanted to go up to help, but Zhou Xiao also stopped him.

It's really too difficult for a girl to do this.

Who knew that Xia Ying was stubbornly controlling retching, and she didn't want boys to help.

"I'll do it myself! I can do it! ”

Xia Ying glanced back at Zhou Xiao, she wanted to prove that she was not a little girl who couldn't do anything!

She must do this by herself!

Seeing Xia Ying so resolute, the boy couldn't say anything.

Zhou Xiao nodded silently, and was also more pleased.

Being able to challenge difficulties shows that this girl's temperament is still relatively rigid and can be cultivated.

After the two catties of garbage were clamped out, Xia Ying continued to wear a mask to analyze the composition of the garbage.

In the end, the results were obtained.

"The proportion of organic matter is as high as 85%, and the rest is what kind of iron box, glass, sediment and other debris."

Zhou Xiao nodded and said: "This data is recorded, you are divided into several groups, and you will check the type and proportion of garbage every day." ”

In fact, most of the municipal waste is organic.

The bags you open are plastic or cardboard boxes, which are organic.

Our leftover meals are organic.

The fruit cores and peels that we throw away are also organic matter.

What are the most common inorganic garbage in the city?

Iron, glass, aluminum, etc.

But many times these things are found and recycled by the people who collect the waste at the first stop when they are thrown into the trash.

About 15% of the 25% of the two catties of garbage are mixed sediment.

After the analysis was completed, a meal of garbage was thrown into the decomposition tank of the strong digestive bacteria.

The situation at the scene did look a little scary.

Due to the very high concentration of strong digesting bacteria, the whole pool is tumbling as soon as the garbage goes down.

A large amount of gas came out of the pool.

Intense digesters produce gases such as carbon dioxide when they break down garbage, and they also release some heat, which causes the solution in the pool to tumble.

The heat released can also be converted into electrical energy, but because the converted electrical energy is low and the equipment is troublesome, this part of the energy loss is lost.

In less than an hour, all the organic matter in the digester has been decomposed.

The filtered sediment is set aside and awaiting sorting by the workers.

The solution in the pool flowed to the next remission.

Because it was an experiment, the large pond with strong digesting bacteria was divided into small pools to maximize the use of strong digesting bacteria.

Otherwise, after each decomposition, all the solution will be poured into the next pool, and the next decomposition will focus on new digestive bacteria, which is also a waste of digestive bacteria.

Fortunately, the laboratory has long had a complete set of methods for cultivating and propagating digestive bacteria, which will not make the cost of digestive bacteria too high.

Zhou Xiao also proposed: "Our pool can be optimized again, the colony does not need to be filled, just pay attention to about one-third, so that each time a batch of garbage is decomposed, and then some strong digestive bacteria are added, and then decomposed several times, so that the whole pool is full, and then enter the next remission, so as to make full use of the activity of digestive bacteria." ”

Zhou's suggestion was quickly adopted by the lab.

The efficiency of the alien digester is also very fast, and after less than an hour, there is a lot of turbid suspended matter in the pool.

These are aggregates of macromolecules of high-energy organic matter.

The things are salvaged, drained, and stacked in the factory.

If it is power generation, then it can be directly thrown into the ionization bacteria pool without drying and compression.

If it is made into a thing, then it needs to be dried, compressed, cut into pieces, etc.

Zhou Xiao first asked the laboratory to make some high-energy food, analyze the content of the substance, and see if it can be eaten.

The composition of the high-energy food was analyzed.

"Most of them are proteins, fats and sugars, and a small amount of inorganic salts (inorganic salts are contained in solution and attached to organic matter), and there is no problem for humans to use them as food," Mo said. We can make standard energy foods by adjusting the content of the ingredients in it, and then through the desalting process. ”

Mo Li handed Zhou Xiao a yellowed piece that resembled a compressed biscuit.

Then he said very naughtily: "Boss, there are dead rats, rotten vegetables, and all kinds of kitchen waste in the pile of garbage just now!" ”
