Xiao Ming, Su Yi and others wore masks on the top floor of the temporary factory of the garbage disposal center, looking at the scene outside the factory through the window - today is the first day of operation of the garbage sorting and treatment company of the Academy of Natural Sciences.

Usually delicate girls wear masks and helmets and become female men, and they direct garbage loaders to dump garbage at the entrance and exit of the factory.

In this way, the garbage is sent to the plant by crawlers, and finally all of it is dumped into a treatment tank with phagocytosis II colonies.

At present, the average cycle of processing a batch of garbage in the treatment pool is six hours, and the treatment efficiency is one meter square meter in 6 hours, which can process 30KG of garbage, that is, 5KG/(hour, cubic meter).

The treatment tank inside the plant is 20 meters long, 30 meters wide and 10 meters deep, with a total of 6,000 cubic meters and is capable of processing 30 tons of waste per hour and 720 tons of waste per day.

Ideally, according to the calculation that the students charge 30 yuan a ton of garbage disposal factory, the revenue for an hour is 900 yuan, and the revenue can reach 21,600 yuan a day.

This is only the first step in the garbage disposal, the second step is that the filter in the treatment tank rises from the very bottom to salvage the untreated inorganic waste and send it to the back of the workshop.

There is an intelligent sorting robot built by the students, which can recognize no matter how small the garbage is or what kind of garbage it is.

The application of quantum chips to garbage disposal is indeed overkill.

The students also opened their minds and did one thing.

Anyway, quantum chips are used, so why not count the types, volumes and quality of various types of garbage and hang them on the garbage sorting and treatment network established by the students?

Some businesses that need recyclable waste (e.g. iron, copper, glass, etc.) can place an order directly online, and the students will arrange for the vehicle to be delivered to their door. This enables direct sales of recyclable waste.

Through the experiment, the students also found that the elements with the highest content of heavy metals in the end-of-life phagocytosis II colony were lead, copper and iron.

In the absence of Xiao Ming's arrangement, the students independently transformed into alchemists to discuss and analyze whether the high-value heavy metals such as copper in the phagocytosis II colony could be extracted and reused.

Regardless of whether or not such discussions and research are fruitful, the spirit of the students must be encouraged.

Jiangcheng produces about 16,000 tons of household waste every day, of which a quarter of about 4,000 tons will be disposed of at the Minsha County Waste Treatment Plant.

At present, the garbage disposal method built by the students can process 720 tons of garbage per day, and only a part of the garbage in the treatment plant can be shared, and most of the garbage is still sent to the suburbs a few kilometers away for landfill according to the old method.

Xiao Ming looked at the operation of the scene and was very satisfied, the usually pampered students sweated like rain here, and they were not squeamish at all.

Yang Li, the squad leader, is still very responsible, although the garbage disposal is only a trial operation, he will not forget to discuss the cost of garbage disposal with Director Min.

Billed on a monthly basis, this is the result of consultation between the two parties.

But after a few days of continuous processing, Director Min found that something was wrong!

Jiangcheng's subsidy to the treatment site is a treatment fee of 60 yuan per ton, which is of course not given by Jiangcheng ZF, but to collect part of the residents' garbage disposal fee, but Director Min will spend 30 yuan per ton to give the garbage to the students, which is not profitable!

Jiangcheng garbage sorting and treatment has not been completely piloted in Jiangcheng, so Director Min's disposal of garbage is very simple - find useful recycling, useless landfill.

The cost of land, environmental protection and management, plus labor, etc., calculates that the cost of garbage treatment plant only needs 15 to 17 yuan per ton.

However, if the garbage is handed over to the students for disposal, the cost per ton is 30 yuan! It cannot be said that Director Min loses blood, but the profit is much less.

Director Min thought that since Xiao Ming brought the students here, he would earn less if he earned less, which could be regarded as giving Xiao Ming face.

"Director Min, I want to discuss something with you. Yang Li came to Director Min's office.

"Squad Leader Yang, please sit down. Director Min was still polite to the students, and poured a glass of water.

Yang Li had just come down from the workshop, he wiped the sweat from his forehead, and drank the water unceremoniously.

Although it is only a practice of a long learning career, Yang Li is still full of passion for his work, and he really sees the whole process from theory to practice, which is the real university life, not just talking on paper, not playing with mobile phones in class, and not reading sentences to PPT by teachers.

After taking a breath, Yang Li said: "Director Min, I am on behalf of our group, but also the Academy of Natural Sciences garbage classification and treatment company to discuss with you, you see that our workshop has greatly improved the efficiency of garbage disposal and protected the environment, there is not a vacant land in the field, we are ready to expand the production capacity of garbage disposal, and then build a plant, the price of land is still according to the original calculation, what do you think?"

Director Min had just taken out a Su cigarette from the cigarette box, and at this time, his hand trembled, and countless white horses galloped past in his heart.

Director Min's mathematics is still good, and if you build another plant, then it will be another garbage disposal line, and the daily processing capacity will increase by 720 tons, which is a total of 1440 tons, which accounts for 36% of the garbage disposal capacity of the entire garbage treatment plant.

"Director Min, what do you think? We can also do our part to improve the treatment process of your garbage treatment plant and protect the environment!" Although Yang Li is twenty-one years old, he is a college student after all, and he has never been in contact with society, so he is still relatively simple.

He was bent on building the latest garbage treatment facility here by the Academy of Natural Sciences, which was a good thing to protect the environment and simplify the garbage disposal process. But I didn't expect that adults have different definitions of good and bad things.

For Director Min, it is a good thing to be able to make money, and it is a bad thing to make less money.

Director Min considered that Xiao Ming was among them, so it was not easy to refuse directly, he said: "Squad Leader Yang, you see that you need an experimental site, I also provide it for you here, and I also support your experiment." ”

Yang Li is a pure straight man, and he immediately said: "Thank you Director Min for your support!"

"Ahem, cough, cough!" Director Min choked on the smoke, coughed a few times in a row, and then said: "I mean, college students still focus on their studies, and the experiment is almost the same, just make up the experiment report and hand it in." Your equipment has been running here for more than 20 days, and I will definitely make up the money for you according to the original agreement. ”

The words are all said and done, and no matter how straight Yang Li is, he can understand the meaning of the words.
