Why can t waste batteries be thrown away, and how to dispose of them?

The hazards of used batteries.

The hazards of waste batteries: The hazards of waste batteries are mainly concentrated in the small amount of heavy metals contained in them, such as lead, mercury, cadmium, etc. These toxic substances enter the human body through various routes, and long-term accumulation is difficult to eliminate, damaging the nervous system, hematopoietic function and bones, and can even cause cancer.

Lead: nervous system (neurasthenia, numbness of the hands and feet), digestive system (dyspepsia, abdominal cramps), blood poisoning and other pathologies. Mercury:

Altered mental status is a major symptom of mercury poisoning. Rapid pulse, muscle tremors, lesions of the oral cavity and digestive system. Cadmium, manganese:

It mainly harms the nervous system.

Waste Battery Disposal:

1. Handed over to the neighborhood committee.

2. There seems to be an activity of exchanging old batteries for gifts.

3. Handed over to the scrap ** station.

Because there are PB ions in waste batteries, harmful substances.

1. Common dry batteries, including alkaline batteries, lithium batteries, and nickel-metal hydride batteries.

It can be disposed of directly in a special sorting bin.

2. Waste batteries containing lead and mercury should be handed over to the waste battery ** institution for them to dispose of.

3. Waste batteries that do not contain lead and mercury can be directly thrown into the urban classified garbage bin.

4. It is not encouraged to collect waste batteries for reprocessing, and it is best to start from the source and try not to use mercury-containing batteries.

5. At present, the best treatment methods for waste batteries mainly include wet and dry metallurgical treatment methods. Wet** is based on zinc, manganese dioxide.

It reacts with acid into the solution, and the solution is purified and electrolyzed to produce metal zinc, manganese dioxide or chemical products and fertilizers. ** after electrolyte.

It contains heavy metals such as mercury, cadmium, and zinc, which is seriously polluting and has high energy consumption. Dry ** treatment of waste batteries is to redoze the metals and their compounds in waste batteries at high temperatures.

Decomposes volatilization and condensation.

Batteries are a waste product that contains toxic substances and should not be discarded. Here are a few ways to dispose of batteries::

At present, many cities have institutions or service points that specialize in used batteries, and you can bring batteries to these places for processing. Give it to the merchant: Some supermarkets, shopping malls, etc. have special waste battery boxes, and you can put the electric branch bending pool into it.

Put in the bin: In the absence of ** facilities, the battery can be put in the ordinary trash can. However, the positive and negative poles of the battery should be covered or glued with tape before being put into the battery, so as to avoid short circuits and safety problems.

In short, we should protect the environment, dispose of waste batteries reasonably, and avoid causing damage to the environment.

Throw it in the battery compartment of the trash.

There are two main types of ordinary dry batteries used in daily life: acidic zinc-manganese batteries and alkaline zinc-manganese batteries, both of which contain mercury 、..

After the waste battery is abandoned, the shell of the battery will slowly corrode, and the heavy metals in it will gradually seep into the water and soil.

The biggest feature of heavy metal pollution is that it cannot be degraded in nature, and the pollution can only be eliminated through purification.

It should be placed in a hazardous bin.

China consumes nearly 10 billion batteries every year! The rate of domestic waste batteries is far lower than the world average, and we need to understand the basic methods of batteries in order to improve from little by little. The following are common methods and a subset of literacy for battery handling.

Method steps.

1. There is no need to put into a special trash can, ordinary waste batteries can be thrown away with ordinary garbage!

At present, there are special waste battery ** garbage cans in some areas, but in fact, with the progress of science, the current ordinary batteries are mercury-free batteries, and the pollution is not large

If you're in an area where there are no waste battery bins, you might as well get a small bag at home, pack them all up, and throw them in the bin all at once.

3. Try to use mercury-free batteries

Some friends say that batteries are harmful, so I try to use rechargeable batteries! Not really!

At present, ordinary batteries in China are mercury-free, which is not very harmful, but the rechargeable battery is very harmful!

4. Turn waste into treasure!

I don't know if you have any similar activities, but it feels good

5. DIY waste batteries can be DIY into some manual But it is not recommended to operate for young children here, and young children like to bite things.

To sum up in fact, you don't have to worry too much about the harm of batteries, the country has banned the sale of low-mercury batteries in the country, so ordinary batteries are not very harmful, and the big Bang Bang can be thrown into the trash can with the garbage that Pudan noisy, but the less garbage the better, haha!

What to do when the battery runs out.

Because waste batteries are very serious to the environment, one battery can pollute 10,000 cubic meters of water. Some even said that waste batteries can cause hazards such as Minamata disease in Japan with the disposal of domestic garbage, and a section of No. 1 waste batteries can make a square meter of land wasted, etc., these reports have caused great repercussions in the society, and there are many people and groups who love environmental protection to carry out or participate in the activities of ** waste batteries.

According to a survey by the old man, an ordinary battery can pollute 600,000 liters of water after being discarded into the natural car, which is equivalent to the water consumption of a person's lifetime, and China consumes 7 billion such batteries every year.

It is understood that 96% of the batteries produced in China are zinc-manganese batteries and alkaline manganese batteries, and their main components are manganese, mercury, zinc and other heavy metals. Whether the waste battery is in the atmosphere or buried deep underground, its heavy metal components will overflow with the leachate, causing groundwater and soil pollution, and will seriously endanger human health over time.

With the miniaturization of electrical appliances, the use of batteries is increasing, and laptops, mobile phones, and digital cameras ......All need to be powered by batteries. Regardless of whether the stove is a disposable battery or a rechargeable battery, waste batteries cannot be discarded at will. This is mainly because the battery contains some toxic and harmful substances, which will pollute the environment once they are discarded at will.

According to some data, a No. 1 battery can permanently render 1 square meter of soil useless, and the polluted water can even reach a staggering 600,000 liters! Therefore, all over the world, waste batteries must be disposed of. Waste battery designation** began in the 70s of the 20th century, when people began to use nickel-cadmium batteries that can be reused after charging.

Its anode material is cadmium, which is a metal that is very harmful to the human body. In the 50s of the 20th century, there were some strange patients in the Toyama Plains region of central Japan, starting with pain in the waist, hands, and feet, followed by generalized bone pain, difficulty in moving, bone atrophy, bending, and softening, and inexplicable fractures. The patient was bedridden day and night, constantly crying out in pain, in the "pain......It hurts, ......He died at the sound of his screams.

The Japanese call this disease "painful disease". Autopsies revealed that some patients had 72 fractures throughout their bodies, and some patients had lost 30 centimeters in height. It was not until 1968 that it was found out that this "painful disease" was caused by the discharge of cadmium-containing wastewater by Japan's Mitsui Metal Corporation.

The sewage discharged by the company directly pollutes rivers and farmland. The local residents drink "cadmium water" and eat "cadmium rice" every day, and over time, some people get "painful disease" Modern medicine has confirmed that this disease is a symptom of acute cadmium poisoning, and this disease is named "bone pain". The destructive effect of cadmium on bones is mainly due to the similarity between cadmium and calcium, which exist in the form of divalent cations in bones, and their "size" is also very similar.

When cadmium enters the body, it will gradually replace calcium, causing people to suffer from "bone pain". The discovery of bone pain has aroused the vigilance of countries around the world. Countries have successively formulated measures to discard nickel-cadmium batteries, and at the same time, they have praised disposable batteries.

This is because most primary batteries use zinc as the negative electrode, such as the commonly used No. 1 or No. 5 zinc-manganese dry cells and coin cell batteries. Zinc metal is very reactive and dissolves in acidic or alkaline solutions and produces hydrogen gas. Therefore, when the battery is not in use, the battery will swell and even burst due to the generation of hydrogen.

To prevent this from happening, a layer of mercury is usually placed on top of the zinc electrode. For this reason, all primary batteries with zinc as the negative electrode contain mercury. Mercury vapor is highly toxic and can cause stomatitis, muscle tremors and mental disorders.

Therefore, disposable batteries should not be thrown away with Sakuramin, otherwise the mercury in them will also pollute the environment. In various batteries, there are a number of other heavy metals and their compounds that, once converted into water-soluble substances, can also contaminate soil and water.
