How should used batteries be disposed of in an environmentally friendly manner?

Industrial enterprises produce waste lead-acid batteries.

Waste batteries such as nickel-cadmium batteries and mercury oxide batteries have been included in the "National Hazardous Waste List" and are subject to relevant laws and regulations.

Strictly implement the management system of hazardous waste transfer declaration and transfer bill. With the improvement of China's battery manufacturing technology, ordinary civilian dry batteries on the market.

It has achieved low or no mercury, with very little pollution, and has not been included in the "National Hazardous Waste List", but the state still advocates the effective use of waste batteries under effective technical and economic conditions. If it is treated centrally, it is recommended to send it to a treatment unit with corresponding qualifications for resource regeneration or harmless treatment.

There are actually many ways to deal with it, and now many communities have garbage cans, and the garbage cans are clearly divided, and one side is the best garbage.

On the other side is the garbage that can not be ** The battery belongs to the garbage that can be **, so it can be thrown into the garbage can, so that it can be well disposed of. Generally, big cities have special **. Some communities have specialized batteries**.

location, sometimes we may not be paying attention. Ask about the community property.

If there is no ** point, it is recommended that you store it in a special container at home, and when you have a certain amount for a year and a half, you can contact a special ** company nearby, or you can check the qualified professional ** unit through the Internet. If you don't have a lot of used batteries at home, you can save them with your neighbors, and you can still dispose of them once a year. Store it in a plastic bucket at the door of the unit, and other residents will see it and slowly get used to throwing the battery in.

No one wants to use used batteries, mainly because of the quantity. In fact, waste batteries still have a lot of profits, and the batteries contain a large number of precious metals, etc., and only a large number of them have refining value. Most families will throw away the waste batteries, on the other hand, some households with high environmental awareness do not know the way, and the company can not get enough batteries, it is difficult to make a profit, and there is no motivation.

There are two environmentally friendly treatment methods for used batteries, one of which is wet **, based on the action of zinc, manganese dioxide and acid into the solution, and the solution is purified and electrolyzed to produce metal zinc, manganese dioxide or chemical products and fertilizers; The other is the dry process**, which makes the metal and its compounds in the waste battery redox decompose and volatilize and condense at high temperature.

The used battery can be put into the trash bin of the special ** old battery, which is environmentally friendly and pollution-free.

After use, put it in a special trash can, and try to use mercury-free batteries.

Put a waste battery station in each community, so that it is processed by the first unified system, so that it is better, sometimes we dare not litter the mobile phone battery, these are impossible to digest naturally, it can not be decomposed, so it is also a little better, according to experts, if a button battery is not well treated, thrown into the river, it can pollute 600,000 liters of water, which is equivalent to the amount of water in a person's life.

More and more used batteries are being generated. If it is not properly handled, it will inevitably pollute the environment, and the ecological environment is closely related to our lives. How harmful are used batteries?

Of course, most of us still don't know much about it. It is necessary to take measures in every possible way, taking a two-pronged approach, starting with adults and minors, and straightening out people's paralyzing and careless thinking that they have nothing to do with themselves. In particular, when the state is now piloting the management of garbage classification, it should be hoped that the whole people will actively cooperate and support to pollute the soil and poison the water source.

There is nothing to do about the ordinary uncle's surname, only to discard it in the garbage can.

Waste batteries pollute the soil and groundwater very seriously, and cannot be naturally decomposed for many years, which will directly affect the living environment of the people in the long run. In order to standardize the management of waste batteries, it is recommended to set up a unified battery department, the country has long introduced a policy of garbage classification, clearly pointing out that waste batteries can not be littered, to be classified and disposed of, which shows that the country attaches great importance to waste batteries, and hopes that each of us can classify garbage.

Therefore, the pollution of waste batteries is mainly chemical pollution, because batteries contain various heavy metals, acids, alkalis, etc., which have a certain degree of pollution to soil, water and air. Serious pollution will make the toxic substances in the water exceed the standard, resulting in undrinkable and unusable; Waste batteries have heavy metal sequelae, can not be discarded anywhere, garbage disposal should be classified**, the investment or investment is cost-effective, through machining treatment, waste utilization, environmental protection, is to protect ourselves.

Do not dispose of waste batteries privately, and do not discard them at will, the general community has a special waste battery station, which can be directly handed over there to a special person to deal with.

Be sure to dispose of it in a place where the state stipulates that used batteries can be landfilled. Wrap the battery in a plastic bag or carton first, and then dig a large pit and bury the waste battery in the pit for landfill. The burning must be done in a good place, and try to choose a mountain or other remote place far away from the human living area to burn to minimize the harm to human beings.

Put it in the trash bin that cannot be **. Because it can't be dusted, it proves that this thing can't be destroyed and disposed of by special means.

<>1. Classification. Smash the waste battery, peel off the zinc shell and the bottom iron of the battery, take out the copper cap and graphite rod, and the remaining black matter is a mixture of manganese dioxide and ammonium chloride as the battery cell. The graphite rod is washed and dried before being used as an electrode.

2. Making zinc granules. The stripped zinc shell is washed and placed in a cast iron pot, heated and melted and kept warm for 2 hours, the upper scum is removed, poured out and cooled, and dripped on the iron plate, and the zinc particles are obtained after solidification.

3. **Copper sheet. After the copper cap is flattened, wash it with hot water, and then add a certain amount of 10% sulfuric acid and boil it for 30 minutes to remove the oxide layer on the surface, and remove the copper sheet from washing and drying.

4. **Ammonium chloride. Put the black substance into the tank, add 60oC warm water and stir for 1 hour to dissolve all the ammonium chloride in water, static, filter, and wash the filter residue twice to collect the mother liquor; After vacuum distillation of the mother liquor until there is a white crystal film on the surface, the chlorinated ammonium crystals are cooled and filtered, and the mother liquor is recycled.

1. It can be stacked according to the requirements of the residential community to reduce pollution.

2. Sort the batteries and put them into the corresponding place.

3. Give it to professional personnel for reasonable use to reduce environmental pollution.

4. It is forbidden to place it next to flammable and explosive items to avoid accidental losses.

5. Find a battery store, so that you can solve the shelving of the battery and bring you some benefits.

The waste electricity and pond that are not used at home should be discarded everywhere and should be thrown into the corresponding garbage bin, so that it will be more environmentally friendly. The batteries on the market are divided into ordinary disposable dry batteries and alkaline mercury-free batteries, the former can be disposed of with household waste, while the latter will cause great harm to the environment, which needs to be specially treated, and can be sent to the station or dealer.

How to throw batteries

With the increase of electronic products around us, the demand for batteries is also increasing, but we all know that there are various chemicals in the battery, if it is aging or can no longer continue to be used, throw it away and cause environmental pollution, so how to throw the battery is more environmentally friendly?

In big cities, garbage classification is being implemented, and we have to throw the battery into the correct garbage bin according to the corresponding garbage classification requirements, and then there will be professionals to dispose of it, which is also a more convenient practice.

It should be noted that the batteries used in general families are ordinary disposable dry batteries, mostly alkaline mercury-free batteries, which can be thrown away with household garbage when they are usually disposed of, and if the batteries in the electric vehicle are mostly lead-acid batteries, they will cause great harm to the environment, so they need to be specially processed and sent to the station is the most correct way.

1. The No. 5, No. 7 and other household batteries have met the national low mercury or mercury-free technical requirements, and can be dispersed with daily life garbage, without the need for centralized unification. However, it should be noted that lead-acid batteries such as button batteries, electric vehicle batteries and nickel-cadmium batteries are still required.

No. 7 battery has met the national low mercury or mercury-free technical requirements.

3. It is often said that battery pollution is mainly because the battery contains cadmium, mercury, lead and other heavy metals, which are highly toxic and remain in the environment for a long time, and will also enter the human body through the food chain to cause chronic poisoning. However, since 1997, the state has made stricter requirements for the production of batteries, and the production of such dry batteries containing a large number of heavy metals has been expressly banned.

On October 9, the State Environmental Protection Administration issued the "Technical Policy for the Prevention and Control of Waste Battery Pollution", which pointed out that "the centralized collection of waste batteries that have met the national low or mercury-free requirements is not encouraged". That is, the common No. 5, No. 7 and other household batteries have met the national low mercury or mercury-free technical requirements, and can be dispersed with daily life garbage, without the need for centralized unification**.

5. However, it should be noted that lead-acid batteries such as button batteries, electric vehicle batteries and nickel-cadmium batteries still need to be used.
