How to reduce waste battery pollution? Why do waste batteries pollute the environment?

Waste batteries contain a large amount of heavy metals and electrolyte solutions such as waste acid and waste alkali.

If a No. 1 battery rots in the ground, its toxic substances can make one square meter of land useless; Throwing a button battery into the water will cause 600,000 litres of water pollution, which is equivalent to the amount of water used in a person's lifetime. Waste batteries contain heavy metals such as cadmium, lead, mercury, nickel, zinc, manganese, etc., among which cadmium, lead, and mercury are substances that are more harmful to the human body.

Mercury, commonly known as "mercury", can cause serious damage to the nervous system, and can lead to madness to death, such as the famous Japanese Minamata disease. Cadmium, which is nephrotoxic, causes irreversible kidney damage, and may be secondary to osteoporosis, osteomalacia and fractures after kidney injury;

Lead can inhibit the synthesis and metabolism of hemoglobin, and can also directly act on mature red blood cells, which is very toxic to infants and young children. Although metals such as nickel and zinc are beneficial substances within a certain concentration range, exceeding the limit in the environment will also cause harm to the human body.

At present, most of China's waste batteries are mixed with domestic garbage and are buried on the ground, over time, after transformation, the battery decays, and heavy metals are dissolved, which will not only affect the germination and growth of seeds, but also cause the pollution of rivers, rivers, lakes, seas and other water bodies, endanger the survival of aquatic organisms and the utilization of water resources, waste acid, waste alkali and other electrolyte solutions may pollute the land, make the land acidified and salinized, and finally enter the human biological chain through various ways, indirectly threatening human health. It's like a ticking time bomb planted around us. Therefore, the collection and disposal of waste batteries is very important, and if not properly disposed of, it may cause serious harm to the ecological environment and human health.

The best way to eliminate sulfide in the battery is to use the pulse repair method

The instantaneous voltage of the pulse when repairing the storage DAO pool.

Generally according to the functional needs embodied in the product capacity, the instantaneous voltage taken is between 60V and 300V, such as the pulse voltage value of the product used for battery life extension is not too large, especially because the pulse voltage value of the battery repair product can be large (if the pulse voltage value is too large to cause damage to the battery plate), the pulse voltage is high, the battery repair time is short, the pulse voltage is low, the battery repair time is relatively long, although the pulse instantaneous voltage is very high, but the average voltage is not high, there is no harm to the human bodyIt's very safe.

Batteries are used in our lives in huge quantities and have penetrated into every corner of our lives and work. At present, the national consumption of batteries is about 10 billion. Common batteries are:

1. Dry battery 2, lithium battery 3, lead-acid battery 4, silver-zinc battery (button battery) 5, alkaline battery. Used batteries are both a pollutant but also a resource. For example, one of the two Swiss companies that specialize in the processing of used batteries is used by grinding old batteries and sending them to a furnace to be heated, where volatile mercury can be extracted, and zinc evaporates at higher temperatures, which is also a precious metal.

Iron and manganese are fused to form an iron-manganese alloy for steelmaking. The plant can process 2,000 tonnes of waste batteries a year, producing 780 tonnes of ferromanganese alloys, 400 tonnes of zinc alloys and 3 tonnes of mercury. The other plant extracts iron directly from the battery and uses a mixture of metals such as manganese oxide, zinc oxide, copper oxide and nickel oxide directly as metal scrap**.

Faced with this situation, what can we do as ordinary people?

1. We must fully understand the hazards of waste batteries. Spread the word about the dangers of it to your relatives, classmates, friends, especially children, and tell them about the dangers of used batteries. It endangers our human health, destroys the environment, affects the growth of crops, endangers the safety of water bodies and the survival of animals and plants.

2. Do not litter waste batteries, maximize the role of old batteries, and minimize pollution.

3. Prepare a small box at home, store the waste batteries in it, and after accumulating to a certain amount, hand it over to the ** waste battery bin.

4. It is recommended that the state set up a policy to encourage waste batteries, adhering to the policy of who produces it. By the battery manufacturer, the battery is carried out. Preferential policies can be set up to encourage battery manufacturers to carry out this business.

5. Following the example of Western countries, the "old for new" system is implemented in battery sales, that is, when buying old batteries, the same number of old batteries must be handed over. If you don't turn in your used batteries, you'll have to pay twice. In this way, the battery recycling model of "manufacturer-wholesale-retailer-user" has been formed.

One, for common dry batteries:

1. It can be directly distributed to the official garbage bin, and should not be collected centrally.

Second, for batteries with high content of harmful substances:

1. Carbon-zinc batteries, Dasheng sensitive part of button batteries, nickel-cadmium batteries, etc., if there are waste battery first-class institutions nearby, hand them over to dispose of.

2. If there is no waste battery organization nearby, and the number of batteries is large, you can contact the local environmental protection bureau or mail it to the first institution in other cities in Navo.

3. If there is no waste battery mechanism nearby, and the number of batteries is small, seal the battery and keep it properly until the first mechanism is found.

III. Special Circumstances:

1. If a large amount has been collected.
