What are the treatment methods and benefits of the four categories of garbage classification?

Household waste. Generally, it can be divided into four categories: can be **garbage.

Food waste, hazardous waste, and other waste.

1. Garbage mainly includes waste paper, plastic, glass, metal and cloth. Waste paper: mainly including newspapers, periodicals, books, various packaging paper, office paper, advertising paper, cartons, etc., but pay attention to paper towels and toilet paper due to the strong water solubility.

Plastics: mainly include all kinds of plastic bags, plastic packaging, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, etc. Glass:

It mainly includes all kinds of glass bottles, broken glass pieces, mirrors, light bulbs, thermoses, etc. Metal objects: mainly including cans, canning boxes, toothpaste skins, etc.

Fabrics: mainly include discarded clothes, tablecloths, face towels, school bags, shoes, etc. Through comprehensive treatment, pollution can be reduced and resources can be saved.

For example, 850 kilograms of paper can be made from 1 ton of waste paper, saving 300 kilograms of wood, and reducing pollution 74 than the same amount of production; 1 ton of plastic beverage bottles per **.

0 7 tons of secondary raw materials can be obtained; Every 1 ton of scrap steel can be made 0 9 tons of steel, which saves 47 costs compared with ore smelting, reduces air pollution by 75, and reduces water pollution and solid waste by 97.

2. Kitchen waste includes leftovers, bones, roots and leaves and other food wastes, which are composted by biotechnology on site, and can produce 0 3 tons of organic fertilizer per ton.

3. Hazardous garbage includes waste batteries and waste fluorescent lamps.

Pipes, waste water silver thermometers, expired medicines, etc., these garbage require special and safe disposal.

4. Other garbage includes bricks, ceramics, muck, toilet waste paper and other wastes in addition to the above-mentioned types of garbage, and sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.

Garbage: sent to the station - sent to the processing plant - made into finished products and flowed to the market.

Wet garbage: crushing – fermenting – nourishing the land.

Dry waste: Waste incineration – power generation.

Hazardous waste: transported and stored separately – safely handled by professional institutions.

We should actively classify garbage, which can not only save resources but also reduce pollution to the environment, in order to maintain our big home, reduce some white pollution, green home classification network, lead everyone to appreciate the benefits of garbage classification!

These garbage can be used through comprehensive treatment, which can reduce pollution and save resources. For example, 850 kilograms of paper can be made from 1 ton of waste paper, saving 300 kilograms of wood, and reducing pollution 74 than the same amount of production; 1 ton of secondary raw materials can be obtained for every 1 ton of plastic beverage bottles; Every 1 ton of scrap steel can be made into tons of steel, which saves 47% of the cost compared with ore smelting, reduces air pollution by 75%, and reduces water pollution and solid waste by 97%.

Kitchen waste (known as wet garbage in Shanghai) includes leftovers, bones, roots, leaves, fruit peels and other food waste. Biotechnology processes compost on site, producing tons of organic fertilizer per ton.

Problems. 1. Atrophy.

State-owned garbage** is shrinking day by day. China was one of the first countries to propose separate garbage collection. Take Beijing as an example:

In 1965, there were more than 2,000 state-owned waste collection stations within the Second Ring Road. After the 80s of the 20th century, its scale shrank severely; In 1997, there were only 16 state-owned waste collection stations within the Third Ring Road.

2. Scavenging army.

There are many problems with the army of scavengers taking its place. More than 10,000 waste pickers "pick up" 100 million yuan from Beijing every year, and at the same time convert waste into new resources, which objectively reduces the burden of garbage disposal, reduces the treatment cost of 1.8 billion yuan, and prolongs the service life of the landfill disposal site. However, these spontaneous waste pickers are all operating without a license, and lack of standardization, inspection and restraint, resulting in serious secondary pollution in the process of garbage pickup, collection, transportation and processing, and their own incidence of infectious diseases is also high.

1. Garbage classification:

1. Food waste: refers to the garbage generated by people in the process of buying, selling, storing, processing and eating various foods. This type of garbage is corrosive, decomposes quickly, and emits a foul odor.

2. Ordinary garbage: including waste paper products, waste plastics, rags and various textiles, waste rubber, broken leather products, waste wood and wood products, broken glass, waste metal products and dust, etc. Ordinary garbage and food waste are the main objects that can be used in municipal waste.

3. Construction waste: including soil, stones, concrete blocks, broken bricks, waste wood, waste pipes and electrical waste, etc. This kind of waste is generally disposed of by the construction unit itself, but there is also a considerable amount of construction waste into the municipal waste.

4. Cleaning garbage: including waste in public garbage bins, cleaning materials in public places, waste after road damage, etc.

5. Hazardous garbage: including dry batteries, fluorescent tubes, thermometers and other chemical and biological dangerous goods, flammable and explosive materials and wastes containing radioactive substances. This type of garbage generally cannot be mixed with ordinary garbage. Second, the way to deal with:

There are three main ways to dispose of garbage harmlessly:

1. Landfill: Landfill garbage investment is small and the treatment capacity is large; The technical requirements are not high. However, it has a large permanent footprint and has a high potential for pollution. In developed countries such as the United States, there have been incidents of landfill pollution decades later.

2. Composting: Treating garbage by composting can turn garbage into organic fertilizer. However, the fertilizer efficiency of this garbage fertilizer is low, the sales are limited, and there is not much room for development.

3. Incineration: Incineration of garbage has the advantages of the most thorough reduction of heat energy and garbage (the volume of garbage is reduced after incineration.

80% 95%), but this method is very expensive. Construction of a daily garbage processing area.

tons of incinerator and attached thermal energy ** equipment, approximately.

7 800 million yuan.

What are the ways to dispose of garbage?

The significance of garbage sorting is as follows:

1. Reduce environmental pollution. Waste batteries contain toxic substances such as mercury, which can cause serious harm to human health; Plastic bags are not easy to decompose, and they can also cause harm to the soil and lead to reduced crop yields, and they are usually mistaken by some small animals, resulting in the death of small animals.

2. It can turn waste into treasure. We can make pen holders, flower holders, etc., which are not only environmentally friendly, but also save resources. And a ton of cans can can also be formed into a ton of aluminum after melting, so that we can mine a certain amount of aluminum ore less, so do a good job of garbage classification, waste into treasure is what we must do.

3. Reduce the work intensity of sanitation workers. To fully popularize the knowledge of environmental protection and garbage to citizens, so as to enhance the awareness of the sanitation industry. After such understanding, we can do a good job of garbage sorting and disposal, which can also reduce the difficulty of sanitation workers' work and make the society full of more love and respect.

4. Reduce carbon dioxide emissions. Reasonable garbage classification can increase the proportion of garbage utilization to a greater extent, which will minimize the demand for raw materials, thereby reducing carbon dioxide emissions, and improving air quality.

5. Make effective use of available resources. Some of the substances in the waste can also be converted into resources, such as: food, fabrics, etc., which can be used to produce organic fertilizers; Waste incineration can also be used to generate electricity, heat supply, etc.

6. Reduce floor space. In China, landfill is the most used garbage disposal method, which will lead to the occupation of a large number of land resources, and the harmful substances existing in some garbage will also destroy the soil, so the classification of garbage can effectively reduce the generation of garbage.

The second is to share the pressure on landfills, many of which take decades or even hundreds of years to degrade.

Garbage classification can make a lot of garbage more effectively recycled, and at the same time reuse a lot of things that have been discarded, which can more effectively improve the national economic capacity.

Garbage classification is a manifestation of the progress of human civilization, a constraint, and a strategy for the long-term and sustainable development of human beings.

Implementing waste sorting can also reduce the degree of injury to workers who distribute garbage, many of whom are injured by accidents while distributing garbage.

Reduce environmental pollution.

Since China's garbage is not sorted, modern garbage contains chemicals, some of which will lead to an increase in people's morbidity. If the garbage is disposed of by landfill or stacking, even if the garbage is landfilled far away from the living place, and the corresponding isolation technology is adopted, it is difficult to prevent the penetration of harmful substances, which will enter the entire ecological circle with the circulation of the earth, pollute water and land, and eventually affect people's health through plants or animals.

Summary. Hello dear dear, I am happy to answer for you: the four most common waste disposal methods are landfill, composting, incineration and pyrolysis.

Hello dear dear, I am happy to answer for you: the four most common waste disposal methods are landfill, composting, incineration and pyrolysis.

Landfill disposal is the most basic treatment method in the state, which simply means landfilling the garbage into the ground, relying on the long-term decomposition effect of natural microorganisms. Further subdivisions include simple landfill, sanitary landfill, compressed landfill, and crushing landfill. Garbage composting refers to the process of transforming organic waste from solid organic matter to humus through bacteria, fungi, worms and other organisms under controlled conditions, and finally achieving stable decomposition and becoming organic fertilizer, which is generally accompanied by microbial growth, reproduction, extinction and population succession.

Waste incineration treatment is the use of high-temperature oxidation to treat domestic waste - the domestic garbage is burned at high temperature, so that the combustible waste in the domestic waste is converted into carbon dioxide and water, etc., and the ash and slag after incineration are only less than 20% of the original volume of domestic waste, so as to greatly reduce the amount of solid waste, and can also completely eliminate various pathogens. For example, kitchen waste or dry waste (other waste) in daily life. However, before incineration, we should pile up the garbage together and wait for the seepage water to be sorted before incineration.

Pyrolysis waste treatment is biomass and plastics, etc., through a clean and efficient pyrolysis gasification system, with low energy consumption to produce high-quality, medium calorific value gas, directly for users to use or through gas-fired power generation equipment into electricity.

Keep three garbage cans at home to separate wet, dry, and hazardous garbage, and then put the garbage into the classified garbage bin of the community. I think we should do a good job at home first, and then expand to the community, and then to a city. Garbage classification depends on everyone's consciousness, consciously putting garbage, and classifying garbage.

Garbage has a huge destructive power on the earth, and if we want to build a green China, we must work garbage. Garbage classification is everyone's responsibility.

The harm of garbage in inappropriate places and unreasonable stacking will induce groundwater, air pollution, and even malaria and virus transmission. Therefore, garbage classification should be classified according to organic degradable, inorganic and non-degradable.

The harm of garbage can be said to be particularly great, because many of them are plastic products, which are difficult to degrade, whether they are burned into ash or landfilled. Garbage sorting can dispose of both the garbage that can and cannot be disposed of, and there are some hazardous garbage like batteries.

The hazards of garbage, such as the toxic gases released by garbage, are not conducive to human health; For example, waste batteries not only pollute the environment and destroy water resources, but also fish drink that water, and people eat this fish will be harmful to cells and nerves. Garbage classification: through people learn categories, consciously dispose of the garbage generated by their own lives.

Improper disposal of garbage accumulation will damage our ecological environment, and land and oceans will be polluted. Garbage classification should be carried out all the time, so that the best garbage can be recycled.

What are the hazards of garbage and how to classify garbage, 4 pictures make it easy for you to grasp.

1. Occupy too much land.

2. Polluting the air.

3. Polluting water bodies.

4. Soil muck.

5. Fire hazards.

6. Nests of pests.

In order to do a good job in garbage classification, it is necessary to carry out correct garbage classification, which can be used in various urban communitiesMr. Cat intelligent garbage sorting equipment

According to the size of the community population, 3-5 garbage sorting points and 1-2 renewable resource points are set up in each community. Residents put the garbage into the station of the renewable resource point, obtain the environmental protection value, and exchange it for the degradable garbage bag printed with the first grade, and then scan the code at the garbage sorting point to deliver wet garbage and dry garbage, forming a closed loop of community garbage classification covered by the whole people.

Garbage classification can be divided into hazardous garbage, kitchen waste, other garbage and can be classified as a good policy.

The purpose of garbage sorting is to use the existing level of production, to dispose of discarded materials according to categories, to make use of effective substances and energy, and to landfill useless waste. This not only improves the level of waste resource utilization, but also reduces the amount of waste disposal. It is an important way and means to achieve waste reduction and recycling.

It also enables the whole people to participate in relevant knowledge training, which can enhance the society's attention to the environmental protection industry, increase the employment rate of sanitation workers, and form an atmosphere of respect and care for sanitation workers.
