I'm collecting golden fingers from all over the world

Rich people have extensive connections, especially companies like Wu Siyuan that employ thousands of people and make annual profits of nearly 100 million.

Even if Wu Siyuan usually doesn't bother to manage connections.

But when he really needs it, just a few phone calls and friends of friends of friends can help Wu Siyuan solve this problem that gives him a headache.

A few days later, the pile of processed garbage in Wu Siyuan's factory was transported away to a medium-sized garbage treatment plant in the suburbs.

Because he had said hello in advance, the person in charge of the garbage treatment plant, after checking the situation of Wu Siyuan's garbage, asked his employees to control the grab bucket and send the several tons of dried garbage to the conveyor, according to different sources. , use various machines to sort them first.

The person in charge of the garbage treatment plant was a middle-aged man with a bald head, a shiny face, and a beer belly. His name was Li Liangtang. He saw that Wu Siyuan looked interested, so he took the initiative to introduce him to him. He said, Wu Siyuan looked interested. In general, these household wastes will be rough-selected first in order to screen out materials larger than 200mm, including glass, bricks and the like.

Haha, there is all kinds of rubbish in the garbage! Li Liangtang said humorously.

Wu Siyuan also smiled.

Li Liangtang continued to introduce Wu Siyuan, After rough selection, it goes into the crusher for crushing, and then enters the manual sorting belt. As you know, the machine is always imperfect, so you need to continue to manually screen out coarse materials.

After manual screening, it will enter the combined screening device. This process is mainly for sorting organic matter, including food waste. After post-fermentation, this part of organic matter can be made into organic fertilizer for sale. .”

However, this type of organic matter often exceeds the standard for heavy metals, so it requires further treatment, which is very costly. Li Liangtang said with a helpless shrug. This is a common problem encountered in domestic garbage disposal, and there has been no good and effective method.

Mr. Li, I want to take away this batch of garbage and organic soil that I transported, and I want to conduct research in the company's laboratory. Wu Siyuan heard this and said to Li Liangtang.

Of course! Li Liangtang said boldly. After a pause, he asked again, Mr. Wu's company also plans to enter the waste disposal industry.

It's just that the laboratory is doing some experiments! Wu Siyuan did not answer directly.

Hahaha, Mr. Wu, this industry is in deep trouble! They are all eating from the government. Without government subsidies, the day lilies will be cold! Li Liangtang said with some emotion.

After all, it is a public service! Wu Siyuan replied.

Hey! Li Liangtang sighed, and suddenly said, By the way, Mr. Wu, there are no plastic products in the batch of garbage you sent over?

Oh, the laboratory here has sorted it first, and the cost is very high. Wu Siyuan said calmly.

Hey, yes! Li Liangtang sighed again after hearing this, The plastic problem is also a pain point in this industry. If nothing else, let's talk about organic soil. It is always difficult to completely sort out plastics. This It will affect the later fermentation and the quality of organic fertilizer.

It's a big problem! Wu Siyuan also echoed, he would not be stupid enough to mention the [Hydrocarbon Degrading Bacteria Mixture].

We can only hope for the development of science and technology in the future. Li Liangtang said.

Then he took Wu Siyuan to visit the winnowing and magnetic separation processes of the garbage treatment plant.

Through these machines, various types of domestic waste can be effectively sorted, greatly reducing manpower...

One day later, Wu Siyuan declined the invitation to eat. After paying the corresponding garbage disposal fees, he had someone drive a truck to Guizhou Province with 800 kilograms of screened organic soil.

One ton of domestic waste can roughly sort out 200 kilograms of organic soil, and 4 tons of domestic waste is equivalent to 800 kilograms of organic soil.

This organic soil is taken back for composting and fermentation, and it becomes organic fertilizer.

Because compost fermentation has special site requirements, the factory Wu Siyuan rented was not suitable for this, so Wu Siyuan had to find another place.

It just so happened that his company's pig farm had a supporting [organic fertilizer factory].

These organic tulla used to be processed just fine.

Moreover, the [Organic Fertilizer Factory] has a laboratory that can help Wu Siyuan detect the heavy metal components in it.

Wu Siyuan is the big boss. After giving the order, his employees were very efficient and quickly vacated the corresponding warehouse to haul the 800 tons of organic soil for composting and fermentation.

There are two methods of compost fermentation, one is aerobic composting and the other is anaerobic composting.

Aerobic composting, also called high-temperature composting, is carried out under aerobic conditions with the help of aerobic microorganisms.

During the composting process, the dissolved organic matter in the organic waste is absorbed by the microorganisms through the cell wall and cell membrane of the microorganisms. The solid and colloidal organic matter first adheres to the outside of the microorganisms, and is decomposed into soluble substances by the extracellular enzymes secreted by the microorganisms. and then penetrate into the cells.

Through its own life activities - oxidation, reduction and synthesis processes, organisms oxidize part of organic matter into simple inorganic substances, release the energy required for life activities, and convert part of organic matter into nutrients necessary for organisms to synthesize new of cellular material, so the microorganisms gradually grow and multiply to produce more organisms.

Generally, compost temperature changes are used as an evaluation index for the composting process.

A complete composting process consists of four composting stages, namely low temperature stage, medium temperature stage, high temperature stage and cooling stage.

Each stage hosts different bacteria, actinomycetes, fungi and protozoa, which use the organic matter in the waste as a source of food and energy until a stable humus material is formed.

Wu Siyuan's [organic fertilizer factory] mainly uses this kind of aerobic compost to produce stable humus substances, and then adds the liquid after Wu Siyuan added [Lingquan Water] to become the factory's flagship product [ Lingquan brand organic liquid fertilizer]!

However, this [organic fertilizer factory] used to directly use pig manure, pig urine, chicken manure and duck manure for high-temperature composting, so the steps were relatively simple.

If the organic matter screened from domestic waste is composted, the steps will be more complicated. After high-temperature composting, [post-processing] must be carried out.

Because mature organic materials after fermentation often contain a large amount of impurities such as stones and incompletely decomposed materials, and the particle size is also very large. In order to improve the quality of compost products, [post-processing] technology and [heavy metal] treatment must be set up.

[Post-processing] generally involves screening, crushing, granulating, and packaging again.

These are what Li Liangtang told Wu Siyuan.
