Where should I collect and throw away the used dry batteries?

Summary. You can 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 for the remaining black matter, it is a mixture of manganese dioxide and ammonium chloride as the battery cell. The ink rods are washed and dried and can be reused as electrodes.

2. After washing the stripped zinc shell, put it in a cast iron pot, heat it and keep it warm for 2 hours, remove a layer of scum on it, pour it out for cooling, and then drip it on the iron plate, and so on until it solidifies, you can get zinc particles.

3. The copper cap can be flattened and then washed with hot water, and then a certain amount of 10% sulfuric acid is added and boiled for 30 minutes to remove the oxide layer on the surface, remove and wash, and dry to obtain copper sheets.

4. Put the black substance into the tank, and then add warm water at 60 degrees Celsius and stir for an hour, so that all the ammonium chloride will be dissolved in water, and the filter residue will be stilled, filtered, and washed with water for 2 times to collect the mother liquor.

5. 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, and then put it into the water and stir it fully for 30 minutes, filter, and then put the filtered cake at 100-110

Small seconds for families! We can use dry batteries to deal with the static electricity on our sweaters, in the fall, when we take off our sweaters, there is always a lot of static electricity on it, we can use batteries to solve it, we use the battery positive electrode to rub on our sweaters, so that we can deal with the static electricity on it, and when we wear it, there will be no static electricity on it! It works very well.

Sharpen scissors After the scissors at home are used for a long time, they will become dull and not sharp, in fact, there is a better way at this time, that is, we use scissors to cut the waste battery, cut a few more times;

Prevent environmental pollution.

The components of dry batteries and rechargeable batteries that we commonly use are mainly composed of zinc scale, iron scale, carbon rod, mercury, sulfide, copper cap, etc. The main component of the battery is a lead-based compound.

According to the Southern **, arsenic, lead, cadmium, chromium and mercury are the five heavy metals that have the greatest impact on the environment, and three of them are contained in batteries, which are lead in lead-acid batteries, cadmium in nickel-cadmium batteries, and mercury as additives in alkaline zinc-manganese batteries. Therefore, littering the above batteries will indeed cause great harm to the environment.

If batteries are discarded in the soil, heavy metals such as lead, mercury, and cadmium can contaminate the soil, and rotten batteries can also contaminate nearby water sources.

Severe heavy metal poisoning can occur if people eat food grown on contaminated soil or drink contaminated water. A rotten No. 1 battery, the heavy metals in which can make a square meter of soil incapable of planting, a rotten button battery can pollute 600,000 liters of water.

First of all, waste batteries are hazardous waste in garbage classification. Hazardous waste needs to be treated safely and irreversibly polluted to groundwater if not thrown directly into the natural environment.

How to use waste batteries abroad.

Japan's Hokkaido Nomura Kosan Company purchases 130,000 tons of waste batteries from the country every year, accounting for 20 of the country's waste batteries, and the collection method is 93 collected through non-governmental environmental protection organizations, 7 collected through various manufacturers. In the past, mercury was mainly used in the first battery, but now the domestic battery does not contain mercury, and the iron shell of the main battery and the "black" raw material in it, and the development and manufacture of secondary products, such as one of the products can be used to produce picture tubes for televisions.

Germany requires consumers to send used dry batteries, button batteries and other types of batteries to stores or waste stations, and stores and waste stations must unconditionally accept used batteries and transfer them to manufacturers for disposal. Waste stations and manufacturers generally only ** batteries containing toxic chemicals such as cadmium and mercury, while 90% of the ordinary zinc-carbon batteries and aluminum-magnesium batteries are landfilled or incinerated as household waste.

The United States is a country with the most detailed legislation on the environmental management of waste batteries, not only establishing a complete waste battery system, but also establishing a number of waste battery treatment plants, and at the same time unremittingly carrying out publicity and education to the public, so that the public consciously supports and cooperates with the work of waste batteries.

Hello, dear kiss, I have the following answer to your question about the waste battery just now: put it away first, and then send it to the collection station if you have the opportunity. There are also special garbage bins and garbage stations for used batteries.

Or send it directly to your local environmental protection bureau. However, at present, the concept of waste batteries is not very popular, so the rate is not high, and the rate is not high, which limits the expansion of the scale of treatment and the improvement of treatment technology, which seriously hinders the industrialization process of waste dry batteries. In some places, waste batteries are piled up in warehouses and have not been well disposed of, some say that the technology is not mature, and some say that it has not yet been industrialized.

In any case, we should start from ourselves, and waste batteries should not be mixed with domestic garbage, but should be disposed of separately. Waste batteries still have to form awareness, everyone does this, will have influence, and related industries will develop. Dear Kiss hopes mine is helpful to you.

Have a great day.
