What are the hazards of waste batteries?

Harm of batteries to human body: Mercury discarded from natural batteries will slowly overflow from batteries, enter soil or water sources, and then enter human body through crops, damaging human kidneys. Under the action of microorganisms, inorganic mercury can be converted into methyl mercury, which will gather in fish. After people eat this fish, methylmercury will enter human brain cells, seriously damage people's nervous system, and even lead to madness and death. The famous Minamata disease in Japan is caused by methylmercury. Cadmium seeps out to pollute the land and water, and finally enters the human body, causing damage to the liver, kidney and cartilage, and in severe cases, causing bone deformation. The leakage of acid and heavy metal lead contained in automobile waste batteries into nature will cause soil and water pollution, which will eventually do harm to people.

Harm of battery to human body: a rotten battery in the ground can make the soil of 1 m2 lose its use value permanently; A grain of button cell can pollute 600 tons of water, which is equivalent to a person's drinking water for a lifetime. Among several substances that pose the greatest threat to the natural environment, batteries contain many kinds of mercury, lead and cadmium. If waste batteries are buried together with domestic garbage, or discarded casually, the leaked mercury and heavy metals will penetrate into the soil, pollute the groundwater, and then enter fish and crops, destroying the living environment of human beings and indirectly threatening human health.

Once the human body absorbs these heavy metals, what diseases will occur? According to experts, mercury is a highly toxic heavy metal, which has great destructive power to the central nervous system of human body. The Minamata disease that shocked China and foreign countries in the 1950s in Japan was caused by mercury pollution. At present, the mercury content of mercury-containing alkaline dry batteries produced in China is 1%-5%, and that of neutral dry batteries is 0.025%. Batteries produced in China consume dozens of tons of mercury every year. Cadmium is easy to cause chronic poisoning in human body, and the main symptoms are emphysema, osteomalacia and anemia, which is likely to paralyze human body. Lead is the most difficult to excrete after entering the human body, which interferes with renal function and reproductive function. Experts believe that battery pollution has the characteristics of long cycle and great concealment, and its potential harm is quite serious. Improper handling will also cause secondary pollution.

Hazard: Most batteries contain mercury. When they are abandoned on the earth's surface, multi-layer metals will oxidize and rust. Mercury will slowly overflow from the battery, enter the soil or seep into the ground, and then enter the human body through crops or drinking water, damaging the human kidney. Here, mercury can also be converted into inorganic mercury, which is converted into methyl mercury under the action of microorganisms and gathered in fish. After people eat this fish, methylmercury will cause damage to human brain cells, seriously damage people's nerves, and even go crazy and die. The Minamata disease that caused a sensation in Japan was caused by methylmercury. A 1 battery rotted in the ground, and the mercury spilled from it was enough to permanently lose the agricultural value of 1 m2 soil.

Waste battery treatment: transport waste lead-acid batteries to the smelter warehouse with special environmental protection vehicles; Pour that electrolyte of the waste lead-acid battery into a sedimentation tank for drug treatment; Disassemble the waste lead-acid battery and send the shell to the plastic recycling plant for professional treatment; Classify the diaphragm of waste lead-acid battery and send it to a professional factory for recycling; The separated waste electrode plates are sent to a large reverberatory furnace to be smelted and made into lead ingots for recycling.
