Tell me how to dispose of the waste batteries at home?

My family is thrown away, so it's better to dig a pit and bury them, so as not to cause disaster.

The trash cans that we have here for waste batteries have been taken away by garbage trucks.

I dispose of the waste batteries at home are to get the trash can to specialize in the waste battery, waste batteries to the environment, water pollution is great, this is also a small act of environmental protection.

There is a trash can near my home that collects waste batteries, and I usually throw all the waste batteries at home into that bin.

Now it is generally discarded at will, and those who are environmentally conscious will choose to bury it deep or send it to the mobile phone store, and the mobile phone store will have personnel to carry it out**. However, the value of waste batteries is not high.

Put the battery into a piece and put it out of reach of the electricity, and the child can't reach it, and sell it when you encounter an old mobile phone. If the village is not able to meet the old mobile phones, it is best to dig a pit and bury them, so as not to cause disasters.

These things can be delivered to the mobile business hall. There's a "green box" there. If you are lucky, you happen to come across mobile and some mobile phone farms to do activities, there will be a ** to add to you, and it is possible to win the ** mobile phone of the current season.

Batteries are better not to be discarded casually, one is to pollute the environment, and the other is dangerous. Generally, there will be a waste battery in a shopping mall or a large supermarket, unified management, unified, environmental awareness, shopping can be brought with the old battery, to be a good citizen of environmental protection. Although it is a little troublesome, it is beneficial to the country and the people.

No matter what type of mobile phone battery it is, it contains metal elements that can cause harm to the environment. However, unlike ordinary batteries, mobile phone batteries also include cobalt, which has extraction value. Therefore, for the disposal of waste mobile phone batteries, it should not just be a simple classification and deep burial treatment like ordinary batteries, but should be actively carried out.

As far as we ordinary individuals are concerned, we should start from me and don't litter casually, don't be afraid of trouble where there is **, everyone is responsible for being a little environmental protection guard! If there is no ** place nearby, go to the mobile phone repair shop, now there are basically mobile phones to trade in or collect old electricity at a low price, protect the environment and make a little money at the same time, why not, with the rapid development of high technology, smart phone functions are more and more. Batteries are also being discarded.

Broken batteries are a big hidden danger.

It must be**, in most cases, there will be a special waste battery in the place of the public trash can, because we are ordinary people, non-professionals, and we don't know how to deal with it, so we only need to unify **, and the treatment is still handed over to professionals.

The main components of the battery we use are nickel-cadmium, nickel-metal hydride, lithium, and the most advanced smart machines are lithium batteries, but no matter which of these three are contained in harmful elements, which have an impact on people or the environment, so do we treat it as a "bad poison" category? Of course not, in fact, there is still valuable cobalt in the battery, so the waste battery has both advantages and disadvantages. It's not useless, and the best way is for the relevant departments to be able to reuse waste.

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.

As a classified garbage: in the community, schools and other places there are special ** battery bins, the kind of garbage can generally only have a small hole, can only let the battery through, other garbage can not be stuffed in, if you are really too lazy to get these batteries, you can directly put them into the special trash can. Industrial Processing:

Waste batteries can be industrially disposed of, the general method is heat treatment, by putting the battery in a high-temperature environment, mercury and other toxic components will evaporate, so that the battery can be non-toxic, and the metal composition can be carried out. It's just that this method is not suitable for individuals to implement by themselves, and heating batteries are also easy to cause. In addition, there are 4 main waste battery treatment methods in China, manual sorting, dry method, wet process and dry and wet method.

Manual sorting and utilization method, is to classify the waste dry battery first, manually sort out carbon rods, copper, caps, zinc skins and various residues, and classify them with the corresponding method to be treated, this method is simple and easy, but the use of labor is more, and the economic benefits are poor. The so-called dry method, also known as smoke method or fire method, is to classify and screen waste dry batteries, crush them, and burn them in a roasting oven at 600-800 degrees, and extract mercury after condensing the discharged gas.

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.

Here's how: Tools: Waste batteries, batteries** trash cans, cast iron pots.

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, and the above substances are collected and processed separately to obtain some useful substances, of which the graphite rod is washed and dried and then used as an electrode; To make zinc granules, the 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 granules are obtained after solidification; **Copper sheet, after the copper cap is flattened, wash the acacia with hot water, then add 10% sulfuric acid and boil for 30 minutes, remove the surface oxide layer, remove the copper sheet, wash and dry; **Manganese dioxide, wash the filtered filter residue 3 times, filter, put the filter cake into the pot and evaporate to remove a little carbon and other organic matter, then put it in water and stir it fully for 30 minutes, filter, and dry the filter cake at 100 degrees Celsius to 11 degrees Celsius to obtain black manganese dioxide; The rest can be solidified and buried deep and stored in abandoned mines.
