Chapter 304

Don't take it at this time!

Xia Ying has no doubt. For a while, Zhou Xiao really asked herself to take 100 samples from ten tons of garbage!

Mo Li looked at Zhou Xiao and whispered, "bully the little girl again!"

Zhou Xiao, why is this so wrong?

Xia Ying had a good life since childhood. She really didn't do dirty and tiring work, let alone rummage in the garbage.

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

Xia Ying wears gloves and holds a clip in her hand.

She needs to take two kilograms of garbage out of a pile of garbage.

"Oh!"

an unlucky year!

As soon as Xia Ying got down, she caught a soft thing. When she opened her eyes, she saw a dead mouse whose whole body had become thinner. She didn't know how long it had died.

A strong stench came to my nose.

"Oh!"

She couldn't help it. Xia Ying took off her mask and vomited out.

It's OK not to take off the mask. When she takes off the mask, the stench directly rushes into her lungs from her mouth. Xia Ying feels she's going to suffocate!

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

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

I didn't know that Xia Ying stubbornly controlled her retching and didn't want boys to help.

"I'll do it myself! I can! "

Xia Ying looks back at Zhou Xiao. She wants to prove that she is not a little girl who can't do anything well!

She must finish it by herself!

The boy couldn't say anything when he saw Xia Ying's determination.

Zhou Xiao nodded silently, also more gratified.

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

After two kilograms of garbage was taken out, Xia Ying continued to analyze the composition of the garbage with a mask.

Finally, the results are obtained.

"Organic matter accounts for up to 85%, and the rest are iron boxes, glass, sand and other sundries."

Zhou Xiao nodded and said, "record this data. Divide yourself into several groups and check the type and proportion of garbage every day."

In fact, most urban garbage is organic.

The bags you opened are plastic or cartons. These are organic.

Our leftovers are organic.

The fruit cores and skins we throw away are also organic.

What are the most common inorganic wastes in the city?

Iron, glass, aluminum products, etc.

But these things are often found and recycled by waste collectors at the first stop when they are thrown into the trash can.

About 15% of 25% of the two kilograms of garbage is mixed sediment.

After the analysis, all the garbage was thrown into the strong digestive bacteria decomposition tank.

The situation at the scene does look terrible.

As the concentration of strong digestive bacteria is very high, the whole pool is tumbling as soon as the garbage goes down.

A lot of gas came out of the pool.

Strong digestive bacteria will produce carbon dioxide and other gases when decomposing garbage, and will also release some heat, which will cause the solution in the pool to roll.

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

In less than an hour, all organic matter in the strong digestive bacteria decomposition tank was decomposed.

The filtered sediment is set aside for sorting by workers.

The solution in the pool flows to the next relief.

Because it is an experiment, the large pool of strong digestive bacteria is divided into small pools, which is to maximize the use of strong digestive bacteria.

Otherwise, after each decomposition, all the solution will be poured into the next tank, 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 reproducing digestive bacteria, which will not make the cost of digestive bacteria too high.

Zhou Xiao also put forward: "we can optimize the pool again. We don't need to fill up the colonies. Just pay attention to about one third. In this way, we can decompose a batch of garbage each time, and then add some strong digestive bacteria. After the whole pool is full, we can enter the next slow digestion, so as to make full use of the activity of digestive bacteria."

Zhou Xiao's suggestion was soon adopted by the laboratory.

The efficiency of alien digestive bacteria is also very fast. Less than an hour later, there are a lot of turbid suspended solids in the pool.

These are macromolecular aggregates of high-energy organic matter.

Things are salvaged, drained and stacked in factories.

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

If it is to make things, it needs drying, compression, cutting and other operations.

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

It's easy to analyze the composition of high-energy food.

Mo Li said: "most of them are protein, fat and sugar and a small part of inorganic salts (inorganic salts are contained in solution and attached to organic substances). There is no problem for human beings as food. We can make standard energy food through desalting process by adjusting the content of ingredients. "

Mo Li handed Zhou Xiao a yellow thing similar to compressed biscuits.

Then he was very naughty and said, "boss, there are dead mice, rotten vegetables and all kinds of kitchen waste in that pile of garbage!"
