Garbage classification ｜ Treatment methods of domestic garbage
household garbage
processing method
I believe many friends in life.
You can see garbage trucks recycling garbage.
After the domestic garbage is thrown-collected-transported
It’s time to deal with it
Different types of garbage
Treatment methods are different.
Let’s take a look at the treatment method of garbage classification.
Disposal methods of recyclable materials
one
Garbage recycling method:
After the garbage is classified, the substances that can be directly used are recycled. Such as: waste glass, plastic, metal, paper, books and newspapers, wood waste cloth, waste oil, etc.
2
Garbage recycling method:
This is a common method adopted by all countries in the world, which can not only completely disinfect and kill pests, but also turn garbage into energy.
three
Garbage composting method:
According to the traditional principle of agricultural fertilizer accumulation, organic garbage and microorganisms in soil are used to transform garbage into organic fertilizer for improving soil.
four
Biodegradation of garbage:
Using a variety of flora with multi-function and high degradation ability to accelerate the decomposition of organic and inorganic substances in garbage, so as to turn waste into treasure and make the best use of it. According to different strains, it can be divided into anaerobic degradation and oxidative degradation. It can be seen that methods should be paid attention to when dealing with recyclable garbage. For example, after the garbage is classified, the substances that can be directly used can be reused. Such as: waste glass, plastic, metal, paper, books and newspapers, wood waste cloth, waste oil, etc.
Harmful waste’s handling method
one
fill in waste
For some harmful waste, landfill can be used for disposal. Landfill is to dig some potholes in advance, then pour some collected harmful waste into it, and then landfill it to let time slowly decompose these harmful waste.
2
set on fire
Some harmful waste can also be treated by incineration, but incineration has a great disadvantage, that is, it will cause great damage to the environment. However, some harmful garbage must be treated by special incineration, which cannot be disposed of by other methods. Therefore, incineration must be adopted to treat some special harmful waste.
three
special handling
There are also some harmful garbage disposal, which must go through special disposal procedures. The procedures are very complicated, but the disposal procedures are necessary, because only through such complicated procedures can these garbage be successfully decomposed and disposed of successfully, so as not to cause greater pollution impact on the environment.
four
Composting method
Some special harmful waste can also be treated by composting. The so-called composting is to pile up these harmful wastes for a certain period of time, and then decompose them through the chemical interaction between wastes. The new substances produced can also be used in other places to realize resource reuse.
Treatment method of kitchen waste
one
Landfill:
After the garbage is classified, the substances that can be directly used are recycled. Such as: waste glass, plastic, metal, paper, books and newspapers, wood waste cloth, waste oil, etc.
2
Fertilization treatment:
After the garbage is classified, the substances that can be directly used are recycled. Such as: waste glass, plastic, metal, paper, books and newspapers, wood waste cloth, waste oil, etc.
three
Feed treatment:
The principle of feed treatment of kitchen waste is to use a large amount of organic matter contained in kitchen waste, and after crushing, dehydration, fermentation and soft and hard separation, the waste will be transformed into high-calorie animal feed, turning waste into treasure.
four
Energy treatment:
The energy treatment of kitchen waste has risen rapidly in recent years, mainly including incineration, thermal decomposition and hydrogen production by fermentation. Incineration has a high efficiency in treating kitchen waste, and it will produce about 5% residues that are good at disposal. Incineration is carried out in a special incinerator, and the generated heat energy can be converted into steam or electric energy, thus realizing the recycling of energy.
five
Microbial treatment:
Microbial treatment of kitchen waste refers to the technology of putting safe microbial inoculum into the waste treatment box, fully mixing and stirring with kitchen waste, and decomposing kitchen waste into water, carbon dioxide and bioenergy by releasing a large number of digestive enzymes. During the working period, microorganisms do not need to be heated, and the waste treatment rate exceeds 99.37%. The produced wastewater can be discharged through pipes or irrigated with green plants, and microbial strains in the water can improve the soil environment.
Huge domestic waste volume
Need a more efficient processing method.
Under the restriction of ecological red line
Higher requirements are put forward for the treatment of domestic waste.
For urban residents,
Domestic garbage can also turn waste into treasure.
The use value is very high.
David hereby appeals to everyone.
Make more use of domestic garbage in life.
Reduce the burden of garbage disposal
Maximize their value.
