【Domestic Waste Treatment Plant】The equipment has been debugged and officially put into operation.
The garbage collected from various garbage stations is first [deodorized], then enters the [storage pool], and then passes through the [feeder] for [rough selection]. The purpose of rough selection is to screen materials above 200mm.
It comes out and after rough selection, it will go through the [crusher]. The function of the crusher is to break the bags or other items into pieces to facilitate entering the next step.
Next is the [Manual Rough Sorting] step. Manual intervention is to screen out bulky materials or other large items.
Then enter the [Comprehensive Screening Device]. At this stage, the machine will separate the [organic soil] and divide it into organic soil below 200mm, or materials between 20-40mm.
These substances are processed through fermentation and will eventually become fertilizer.
This is followed by [manual sorting] to sort out the coarse materials that were not cleaned in the previous sorting.
Followed by [Magnetic Selection], [Wind Selection], [Selection].
The function of [magnetic separation] is to sort out metal items through electromagnetic reaction. These metals can be recycled or sold, which is an income for the garbage treatment plant.
The [Wind Selection] is to filter out heavy objects between 40-200mm.
[Selection] is to sort out some available [combustible debris] for recycling purposes.
The last step is [packaging], where the plastic and paper are packed into shapes and finally sold.
30%-40% of domestic waste can be recycled.
Take plastics for example. Our country uses 4 billion plastic fast food boxes, 500-700 million instant noodle bowls, and billions of disposable chopsticks every year. These account for 8-15% of domestic waste.
1 ton of waste plastic can be recycled into 600 kilograms of diesel. Recycling 1,500 tons of waste paper can avoid cutting down the trees used to produce 1,200 tons of paper.
One ton of cans can be melted to form one ton of good aluminum blocks, which can save 20 tons of aluminum ore.
Turning waste into treasure, garbage sorting and recycling is a hugely profitable industry - the premise is that the technology must keep up!
If the treatment process cannot keep up, it will lead to a significant increase in the cost of garbage disposal, which will neither make money nor achieve the purpose of environmental protection.
The normal domestic waste sorting and processing process was introduced before.
However, such a process is inevitably bound to have some flaws.
One of the main problems is that neither machines nor humans can remove plastic 100%.
This results in the final processed [organic fertilizer] containing a large amount of plastic.
These plastics have been cracked into extremely tiny particles and cannot be completely removed according to existing technology. This results in the production of [organic fertilizer] being of poor quality and not accepted by the market.
Oh, by the way, these [organic fertilizers] also have a problem of excessive heavy metals.
It is also a difficult problem to deal with.
This is also why it is difficult to make a profit in the waste disposal industry!
To put it bluntly, the existing technology is immature!
This is still based on state subsidies.
Otherwise, it’s really a big loss!
However, other people will suffer losses in this industry, but Wu Siyuan has so many black technologies at hand, which is different.
[Base Car Butler] He Youman redesigned the processing process based on the black technology Wu Siyuan had at his disposal.
The previous processes remain unchanged. In the first [Manual Rough Sorting], the staff will sort out bulky materials, usable textile items, glass, harmful batteries and relatively clean plastic bags and plastic bottles, and then these daily life
The garbage will go into a secret [storage bin].
Inside this [Storage Bin], there is a secret device that will inject the appropriate amount of [Hydrocarbon Degrading Bacteria Mixture]!
These [hybrid hydrocarbon-degrading bacteria] are the nemesis of petroleum products. In the movie "The Agent Next Door", these degrading bacteria not only swallowed up a barrel of oil in a short period of time, but also destroyed the plastic belongings of a female spy.
High heels swallowed up everything.
After they enter the [storage bin] and encounter [food] such as plastic, they devour and multiply like crazy.
If you open the [Storage Bin] at this time, you will find that the entire [Storage Bin] seems to be dyed with a layer of yellow.
Not long after, all the rubber, nylon, and plastic in the entire [storage bin], even tiny particles invisible to the naked eye, were swallowed up by degrading bacteria and released a large amount of high temperature.
Because the high temperature is fully covered from the inside to the outside, more than 95% of the harmful substances in the garbage, including bacteria and poisonous insects, are killed and cooked.
The solution in the garbage pile also evaporates and rises and is adsorbed by the device installed above, and the garbage in the [storage bin] becomes dry.
Then enter the [preliminary screening process] and [comprehensive screening process] to separate metal substances, large items, paper, and organic soil.
Metal items will be recycled or sold.
The same operation applies to large items.
The paper and the first sorted plastic will be thoroughly cleaned, then packaged and compressed, and finally sold to collect funds.
As for the organic soil, it will be combined and sent to the [storage tank].
At this time, we need to solve the problem of excessive heavy metals.
Use the [Shen Nong No. 1] earthworms that Wu Siyuan previously cultivated. This kind of earthworms can enrich heavy metals in their bodies by swallowing organic soil, excreting earthworm castings.
Finally, the earthworms are drawn out through the [Mutated Sarracenia] potted plant and used as nutrients for the [Mutated Sarracenia].
The organic matter undergoes anaerobic fermentation - here is a little surprise.
[Hydrocarbon-degrading bacteria mixture] will die immediately when there is no petroleum product food.
Their corpses were mixed with organic matter.
But unexpectedly, when organic matter undergoes anaerobic fermentation, the corpses of these degrading bacteria act like a catalyst, not only quickly decomposing dead branches and leaves, but also increasing the gas production efficiency by 20%.
This leads to an increase in the effect of biogas power generation!
The final biogas residue is made into organic fertilizer and sold to [Lingquan Organic Fertilizer Factory] at market prices, forming a complete chain.
After the entire process, excluding the cost of the big killer [Hydrocarbon Degrading Bacteria Mixture], Wu Siyuan's [domestic waste treatment plant] costs more than 50% less than traditional methods, or even higher.
.
The [Hydrocarbon Degrading Bacteria Mixture] was obtained by Wu Siyuan from the movie world of [The Agent Next Door]. The production cost is actually not high, almost zero, so the cost in this aspect can be ignored for him.
.
The cost of a [domestic waste treatment plant] generally includes labor costs, equipment depreciation costs (this is especially exaggerated), infrastructure costs, operating costs, etc.
