Trash Classification Practice Survey Report

In order to figure out an event or a situation, it is necessary to investigate it carefully and form a survey report based on the materials we have got. Come to refer to how to write an investigation report, the following is my help to organize the garbage classification practice investigation report, welcome to share.

Garbage classification practice survey report 1

I. Overview

(a) Investigation time:

(b) Investigation location: xx village, Changsha City

(c) Investigation method: the way of visits, the use of the observation method of investigation method

(d) Investigation object: Sha City Kaifu District, Loudaohe Town, Daming Village, garbage disposal

(E) Investigation Background: Now life is getting better and better, people's standard of living continues to improve, the increase in consumption, bringing economic development. The same also brings more garbage. Garbage has increased. The air is getting worse and worse, the health is getting worse and worse, and all kinds of garbage are appearing constantly and more and more. There are fewer and fewer places for landfill, so if this continues, will we have to live on the garbage heap? I think it's worth thinking about, this I launched an investigation, I chose a village in Kaifu District, Changsha City, to investigate the situation of garbage dumping, removal and disposal there.

The results

The results are still not very satisfactory, because I can't see the future if we go on like this, because the generation of garbage is synchronized with the treatment of garbage! Because in my opinion, waste disposal should be faster than waste generation, which means that waste is decreasing, not just being disposed of and generated! Some of you may think that garbage disposal is not a big deal. Then you are wrong. Take a look at the importance of dealing with garbage in terms of its dangers. Garbage is bound to exist in people's lives. If it can not be handled in time, a large amount of garbage is piled up randomly and hoarded for a long time, it will occupy land, produce odor, cause serious pollution to the atmosphere, water and soil, and lead to the breeding of flies, insects and rodents, which will threaten the health of the residents. Therefore garbage is a great burden to the city. Garbage disposal is not easy, can be summarized as follows: First, from the average composition of the garbage from the point of view of most of the residents' living fuel to coal-based, coal ash accounted for a large proportion of the total amount of garbage, the market and the kitchen organic waste, and then there are streets and yards of the leaves and dust, etc., and there is also mixed with a certain amount of glass, plastics, bad metals and other impurities, it is difficult to burn and destroy. Secondly, fertilizing with this kind of garbage will make the land ballasted. Thirdly, in the past, the garbage is buried in the ground, but now it is found that the garbage buried in the ground will destroy the groundwater, and the landfill site can not be put to great use. Moreover, all available landfill sites in the suburbs and urban areas will soon be exhausted, so it is urgent to find a way out for the garbage. Also, although some regulations have been put in place to protect the environment and sanitation, they are not strictly enforced and are not very effective. Littering exists everywhere and the amount of garbage is still increasing. How to deal with the garbage is really an urgent matter.

Three Problems

(a) The amount of daily garbage is increasing.

(b) Waste disposal is still dominated by sanitary landfills, taking up a lot of land resources. Nowadays, when land resources are very precious, if the growth of landfills is effectively reduced and used for economic development, it will have an immeasurable effect.

Four, response methods

(a) Reduce the occupation of land: some substances in the domestic waste is not easy to degrade, so that the land is seriously eroded. Garbage classification, to remove can be recycled, not easy to degrade the material, reduce the amount of garbage up to 50% or more.

(2) Reduce environmental pollution: discarded batteries contain metal mercury, cadmium and other toxic substances, which can cause serious harm to humans; waste plastics in the soil can lead to crop yield reduction; abandoned waste plastics are accidentally eaten by animals, resulting in the death of the animal accidents happen from time to time. Therefore, recycling can reduce the harm.

(3) Waste to treasure: China's annual use of plastic fast-food containers up to 4 billion, instant noodle bowls 500-700 million, waste plastic accounted for 4-7% of the domestic waste. 1 ton of waste plastic can be smelted back to 600 kilograms of diesel fuel. Recycling 1,500 tons of waste paper can avoid cutting down forests used to produce 1,200 tons of paper. One ton of cans can be melted down to form one ton of very good aluminum blocks, which can reduce the mining of 20 tons of aluminum ore. 30%-40% of the production waste can be recycled and should be treasured as a small and profitable resource. We can also use cans to make pencil cases, both environmental protection, but also save resources.

V. Specific classification of garbage

(a) Recyclable garbage, mainly including waste paper, plastic, glass, metal and fabric five categories. Waste paper: mainly including newspapers, periodicals, books, a variety of wrapping paper, office paper, advertising paper, cardboard boxes, etc., but note that paper towels and toilet paper due to water solubility is too strong not to recycle. Plastic: mainly including various plastic bags, plastic packaging, disposable plastic lunch boxes and cutlery, toothbrushes, cups, mineral water bottles, toothpaste skins and so on. Glass: mainly includes various glass bottles, broken glass pieces, mirrors, light bulbs, thermos flasks and so on. Metal objects: mainly cans, can boxes, etc. Fabrics: mainly including discarded clothes, tablecloths, washcloths, schoolbags, shoes, etc. Recycling through comprehensive treatment can reduce pollution and save resources. For example, each recycled 1 ton of waste paper can make good paper 850 kilograms, saving 300 kilograms of wood, than the same amount of production to reduce pollution by 74%; each recycled 1 ton of plastic beverage bottles can get 0.7 tons of secondary raw materials; each recycled 1 ton of scrap iron and steel can be refined 0.9 tons of steel, smelting with ore to save 47% of the cost of smelting to reduce air pollution by 75%, reducing 97% of the water pollution and solid waste.

(ii) food waste, including leftovers, bones, vegetable roots and leaves, peels and other food waste, composted by biotechnology on-site treatment, each ton can produce 0.3 tons of organic fertilizer.

(c) Hazardous waste, including waste batteries, waste fluorescent tubes, waste water silver thermometers, expired medicines, etc., which require special safety treatment.

(d) Other garbage, including in addition to the above categories of garbage, brick ceramics, slag, toilet paper, paper towels and other difficult to recycle waste, to take sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.

Six, conclusion

Environmental health depends on everyone, garbage disposal is equally indispensable to everyone's cooperation, if everyone can not litter, less garbage, I think now there will be no difficult situation to deal with garbage. As of now it seems that this possibility is not very difficult to achieve. There is a saying that one man's trash is another man's treasure! One can imagine. Garbage is not completely useless!

Trash classification practice investigation report 2

As the population grows, there is more and more domestic garbage. Many countries and regions carry out incineration of garbage to alleviate the mountains of garbage. Even landfill certain garbage! These improperly handled methods not only make rivers polluted, but also jeopardize human health. In order to solve this problem, people take the method of garbage classification, the following is my investigation.

1. Classification of household garbage.

In order to make garbage classification a habit in people's lives, I investigated the situation of garbage classification in the neighborhood. To ask about the implementation of the classification of household garbage and the problems in the implementation.

Investigation time: February 2, 20xx ~ February 4.

Place of investigation: River Garden District North, Building 5, Unit 3.

Survey content: the residents of this unit on the classification of garbage and the importance of the situation.

Format: photographs and interviews with residents

Survey results: accurate calculation, found that 10% of the residents pay special attention to the classification of household garbage and sorting out the household garbage. 40% of the people think that it does not matter, what is always the kitchen garbage and toilet garbage together with the pocket. 20% of the people think that this is none of his business, so that the garbage dump to sort it out on the line. 30% of the people want to sort out the heart but do not know how to sort out. I don't know how to do it.

2.

Garbage sorting, as the name suggests, is the process of categorizing different kinds of garbage. It is classified according to the composition of the garbage, the amount of garbage generated, and in conjunction with the way local garbage is utilized for resources and treated.

There are four types of garbage, namely hazardous waste, other garbage, recyclables, and kitchen waste. Recyclable garbage is generally loaded with waste paper, scrap metal, plastic bottles and so on, which can be recycled; hazardous garbage is waste batteries, cell phones, which are harmful to the environment and the human body; kitchen waste is the leftover fruits and vegetables from cooking and eating, etc.; and other garbage is the garbage that doesn't belong to the above three kinds of garbage, such as cigarettes, clothes, and so on.

3, classification of publicity and expansion

In the community, the elevator can be seen inside the garbage classification of publicity, conspicuous red paper printed in black, hanging in the elevator next to the button, used to remind people. Every homeowner also receives a text message from the property owner reminding them of the importance of garbage classification.

4, the residents of the current situation of garbage classification:

According to my observations these days, the residents of the garbage classification is not very ideal, the garbage cans also have a lot of garbage that does not belong to the inside of the garbage cans, garbage cans are full or even full of time, you can also see the garbage cans outside the scattered all kinds of garbage, and sometimes the stench spreads, resulting in people The fact that they are not in a position to do so makes it difficult for people to breathe, and we still need to improve on this aspect of categorization.

5. My thoughts and reflections.

I think that the classification of garbage is something that we should do each of us, it is our responsibility to do. Humans are progressing, then our homes should not be dirty and messy, but should be neat and beautiful. To take a step back, because of the large amount of garbage, many of the freshwater rivers on the earth have been polluted, and these untimely disposal of garbage will slowly breed bacteria, people, as well as animals may be infected with diseases. And garbage classification can effectively help us deal with the garbage, which is not so difficult, if most people pay attention to it, then it may be able to reduce some of the harm to us, to the earth.

6. Experts remind.

Humans have only one Earth, and the Earth's resources are limited. How to use the limited resources of the Earth to realize the 'infinite development of mankind? Then it is necessary to make the earth's resources can be perpetually recycled and regenerated. Undoubtedly, the classification and recycling of the raw tip waste should be a vital part of this recycling carcass.

7, real events.

Of the 57 people who died in the area within about 1.2 kilometers of the waste incineration site in Ibaraki Prefecture, Japan, 24 people died of cancer, with a ratio of 42.1%; and of the 167 people who died in the area outside of 1.2 kilometers, 34 people died of cancer, with a ratio of 20.4%.

8. Maintaining the environment starts with me.

01. A little bit of effort is a source of sustainable resources.

02, all a classification heart, garbage can become gold.

03, governance "white pollution", building a green home.

04, the chaps, don't let the garbage jump wrong pit.

9.

Everything is about starting with children, I suggest that children from the age of three or so, teach children the reason for the classification of garbage and the reasons, and even now a lot of young people will not be able to distinguish which category of garbage belongs to the situation in the school can be a semester dedicated to a section of the garbage classification of the course, tell students to classify the majority of garbage in the attributes of garbage, telling them the benefits of garbage classification, why it is so important. The students can be told the properties of most of the garbage, the benefits of garbage classification, and why it is important to do so. At the same time, adults should also have a role as a model, and the local government should also respond positively to people's garbage classification. You can also let some representative and authoritative public figures to do the publicity of garbage classification, and the response of the residents may also be stronger.

Finally, I hope more . People unite to contribute their small part to the tomorrow of our country, even the tomorrow of the earth.

10, Thoughts.

Trash is the main impact on life, we must pay attention to the classification of garbage, better to maintain the health of the body, cheers!

Garbage classification practice investigation report 3

First, the problem:

With the development of social and economic, environmental pollution is becoming increasingly serious, urban garbage can be seen everywhere. According to relevant information: in the past 10 years, China's urban garbage average annual growth rate. In the country's 400 large and medium-sized cities, 2/3 of the city has been in the garbage surrounded. Our country has reached 6 billion tons of garbage over the years, encroaching on more than 500 million square meters of land. At present, China is still producing new garbage at a rate of hundreds of millions of tons per year. How is this garbage produced and how is it disposed of? These questions have aroused great research interest.

A survey of the current situation:

Early in the morning, both sides of the street is everywhere visible is the garbage, some wrapped in plastic bags, some just randomly disposed of on the ground, and some placed in the trash can.

Passing by the hospital, I saw some expired medicines, discarded mercury thermometers and some bottles of medicine, infusion sets were discarded in the corner of the hospital, the garbage emits a pungent smell, so I dare not approach.

In one corner of the factory, discarded batteries, old machines, circuit boards, and broken glass and boards are piled up. Batteries have been broken, leaking out the liquid inside. Waste batteries have been known as "miniature killers", we can imagine, these waste batteries into the soil, will cause much harm to the land.

Vegetable markets, discarded fish and vegetables arbitrarily piled up in the road, flies buzzing, such a scene makes me feel surprised, can not buy out of the food are so randomly discarded?

A sanitation worker told me that these piles of garbage have to be sent to a certain place for landfill or incineration.

Three of the hazards of garbage:

Randomly disposing of garbage is potentially very harmful, so a lot of garbage needs to be turned into landfill. In the process of incineration, how many toxic gases will be produced, jeopardizing people's health? We are constantly turning our limited resources into garbage, and burying or burning them, and in the long run, where will our future generations go to find the energy they need?

Four: Classification of Garbage Disposal:

Is there nothing we can do about the pollution of garbage? No, according to our research, garbage can generally be divided into four categories: recyclable garbage, food waste, hazardous waste and other garbage.

Recyclable garbage is sent directly to the relevant factory for reprocessing and waste utilization. For example: 1 ton of waste paper can be recycled 800 kilograms of good paper; recycled batteries can be extracted rare metals zinc, copper and manganese dioxide; recycled waste plastics can be smelted back to fuel.

Kitchen waste, such as leftovers and lettuce, eggshells and peels, vegetables, vegetables and leaves, etc., can be piled up, so that the fibrous and organic matter of the waste decay, into fertilizer to improve the soil.

Harmful garbage, such as waste fluorescent tubes, expired medicines, etc., can be concentrated and incinerated to minimize the hazards of garbage.

Other garbage, such as ceramics and slag, which are difficult to recycle and are not harmful to the environment, can be effectively landfilled to minimize pollution of groundwater, soil and air.

Fifth, our thinking:

Relevant statistics show that: China's annual value of waste available but not utilized amounted to 25 billion yuan, about 3 million tons of scrap steel, 6 million tons of waste paper has not been recycled. The recovery rate of waste plastics is less than 3%, and the recovery rate of rubber is 31%. Only more than 6 billion waste dry batteries thrown away each year contain more than 70,000 tons of zinc, 100,000 tons of manganese dioxide. Classification and recycling of waste is valuable:

Waste paper:

Recycling 1 ton of waste paper can be recycled out of 800 kilograms of good paper, you can save 17 trees, saving 3 cubic meters of landfill space, less soda ash 240 kilograms, reduce the pollution emissions of papermaking by 75%, saving the paper making energy consumption and each piece of paper can be recycled at least twice.

Waste plastic:

Plastic from the earth's non-renewable resources - oil, recycling waste plastic is to save oil. All waste plastics, waste lunch boxes, food bags, woven bags, flexible packaging boxes, etc., can be refined back to fuel oil by using the technology of reducing waste plastics to gasoline and diesel; liters of unleaded gasoline or diesel can be produced from 1 ton of waste plastics.

Waste glass:

Waste glass recycling, not only can save natural resources, but also reduce energy consumption by about 32%, reduce air pollution by 20% and 50% of water pollution. 1 ton of waste glass back to the furnace than the use of new raw materials to save 20% of the cost of production. The benefits of recycling one ton of waste glass to the environment and resources are: you can save 720 kg of quartz sand, 250 kg of soda ash, 60 kg of feldspar powder, 10 tons of coal, electricity 400 degrees.

Waste aluminum cans:

Waste cans can be 100% dissolved and recycled countless times into new cans, but also, can be made into parts of cars and planes, etc., and even furniture. Recycling aluminum cans saves 95% of the energy needed to make new cans and reduces air pollution by 95%. Throwing away an aluminum can is the same as wasting half an aluminum can of oil.

Organic matter:

More than 40% of the garbage we still get out of our house every day is kitchen garbage such as fruit peels, egg shells, vegetable leaves, leftovers, and so on, which can be processed into organic fertilizers or feeds by composting and fermentation methods.

Waste batteries:

Mercury and cadmium contained in waste batteries are highly polluting toxic heavy metals, but recycled batteries can extract rare metals such as zinc, copper and manganese dioxide.

Six, our proposal:

1, through the publicity, so that the people understand the importance of garbage classification;

2, in the residential areas, vegetable markets, hospitals, factories and other places to set up the classification of garbage bins, so that it is easy for sanitation workers to classify all kinds of garbage disposal.

Today, we went to the Zhejiang Museum to make a survey on ceramics. We divided into a, b two groups, a group on the first floor of the exhibition hall to investigate pottery, b group on the second floor to investigate porcelain. I participated in the a group.

By watching the introduction and listening to the explanation, I know the pottery and porcelain is not the same thing. Pottery appeared earlier than porcelain, pottery is made of smaller particles of earth fired into a vessel. In ancient times, pottery was mainly used for rituals and burials.

Porcelain appeared in the Eastern Han Dynasty, which is a smooth glaze on the surface of pottery. Depending on the color of the glaze, porcelain is divided into many types, including celadon and white porcelain ...... The famous celadon, due to the presence of iron in the glaze, takes on a jasper-like green color."

In ancient times, pottery and porcelain were used in rituals, heirlooms, and other activities. And in modern times, ceramics turned into household items, which help people to pan rice, serve rice, and become indispensable items for family life.

Pottery and porcelain are indispensable both in ancient and modern times, and are the crystallization of the wisdom of the ancient Chinese working people.
