Six hazards of garbage unclassification. More and more people pay attention to garbage classification. Only by sorting garbage can we build our beautiful home. There will be a lot of harm if garbage is not classified. Then I'll show you the six hazards of garbage unclassification in detail.
The six hazards of unclassified garbage (1 1) and 1 are environmental pollution. Because garbage is not classified, garbage is piled up everywhere in fields and under bridges, which pollutes a lot of land environment.
2. The second hazard is air pollution of garbage. If they are not classified, they will all be piled up together, which will rot, stink and deteriorate, produce an unpleasant smell and pollute the air.
The third hazard is that it is easy to cause fire. There are some inflammable and explosive substances or some chemical reagents in the garbage, which are not classified. If all piled together, it is easy to cause a fire, and the consequences are unimaginable.
4. Unclassified garbage will also lead to garbage, which will bring a lot of workload to the staff and occupy a lot of human resources in the later stage.
The fifth hazard is the garbage that can infect diseases. If not classified, there are some medical wastes, which contain germs or viruses. If it is not classified, it will infect some diseases, especially infectious diseases.
6. The sixth hazard is that it will pollute the water source garbage. At present, the main treatment method is landfill. If the amount of garbage is large, the amount of landfill will be large, and the garbage also contains some toxic substances, which will pollute the groundwater after being buried deeply.
Six hazards of garbage unclassification II. Garbage classification standard
In China's garbage classification standards, garbage is mainly divided into four categories, including recyclables, other garbage, kitchen garbage and harmful waste. Different types of garbage have different treatment methods. Specific garbage classification standards and treatment methods are as follows:
1. Recyclable materials: Recyclable materials include waste paper, plastic, glass, metal and cloth. The main treatment method of these wastes is comprehensive recycling. 1 ton waste paper can make 850kg paper, 1 ton plastic beverage bottle can get 0.7 ton secondary raw materials, and 1 ton scrap steel can make 0.9 ton steel. The minimum profit per ton can reach several thousand yuan.
2. Other garbage: major wastes that are difficult to recycle, such as brick and tile ceramics, muck, toilet waste paper, paper towels, dust, food bags, etc. In the classification of other garbage. The disposal method of these wastes is mainly landfill, which is easy to degrade, will not have a great impact on the soil, and can effectively promote the ecological cycle of nature.
3. Kitchen waste: Kitchen waste is all kinds of food waste produced when we usually eat, mainly including leftovers, bones, roots, leaves, peels and other food waste. The treatment of this kind of garbage is mainly biotechnology compost, and the natural organic fertilizer can be used in the production of green food to realize the recycling of resources.
4. Hazardous wastes: Hazardous wastes mainly include heavy metals, toxic substances harmful to human health or wastes harmful to the environment, including cosmetics, medical supplies and paints. The treatment of hazardous waste is mainly based on the national Regulations on the Treatment of Hazardous Substances, and related technologies are adopted for separate recovery or landfill treatment.
Harm of direct garbage disposal
China's garbage disposal methods are mainly incineration and landfill. Waste incineration is easy to produce dioxins, which is extremely harmful to human body. At present, in China, only a few manufacturers meet the standard. In addition, other polluting gases released by garbage incineration will also cause great pollution to the atmosphere. Mixed landfill treatment of garbage will not only cause flies flying, sewage overflowing and stinking, but also pollute soil, groundwater, vegetation and underground life for a long time.
China's garbage disposal capacity often can't keep up with the amount of garbage produced. As the capital of Beijing, there is still a gap of nearly 80 million garbage disposal capacity every day, and the excess garbage can only be piled in the open air. What's more, when garbage is in the ecological cycle in nature, it often transmits pollution to human body through the conduction of biological chain. It is hard to say that vegetables and meat sold in the market are not polluted by related garbage.
Garbage sorting is an important activity and must be popularized. More than one third of China's big cities are surrounded by garbage, and the lag of garbage disposal capacity can only make garbage naturally degrade in nature. The underground participation of citizens in garbage disposal is also one of the main reasons for the overflow of garbage. To further promote garbage sorting and disposal, it is necessary for the whole society to form a sense of unity and cohesion.
