How many batteries did China consume in 2006?

At present, the annual output of batteries in China exceeds 654.38+08 billion, accounting for more than 30% of the world's total battery output, and the annual consumption reaches 7-8 billion, but the recovery rate is less than 2%.

Battery composition: dry battery and rechargeable battery composition: zinc sheet (iron sheet), carbon rod, mercury, sulfate, copper cap; The battery is mainly composed of lead compounds. For example, 1 waste zinc-manganese battery weighs about 70g, including 5.2g carbon rod, 7.0g zinc skin, 25g manganese powder, 0.5g copper cap and 32g others.

The harm of waste batteries is mainly concentrated on a small amount of heavy metals, such as lead, mercury and cadmium. These toxic substances enter the human body through various channels, and long-term savings are difficult to eliminate, damaging the nervous system, hematopoietic function and bones, and even causing cancer. Lead: diseases such as nervous system (neurasthenia, numbness of hands and feet), digestive system (dyspepsia, abdominal cramps) and blood poisoning. Mercury: Mental state change is the main symptom of mercury poisoning. Rapid pulse, muscle tremor, oral and digestive diseases. Cadmium and manganese: mainly harm the nervous system. 3. Ways for waste batteries to pollute the environment: The components of these batteries are sealed inside the battery box during use and will not affect the environment. However, after long-term mechanical wear and corrosion, heavy metals, acids and alkalis will leak out, enter the soil or water source, and enter the human food chain through various channels. The process is briefly described as follows: pool soil microorganisms, animals, circulating dust, crops, food, human nerve deposition.

Heavy metals ingested by other water plants and food-borne organisms from the environment can accumulate in thousands of higher organisms step by step through the biomagnification of the food chain, and then enter people's bodies through food and accumulate in some organs to cause chronic poisoning. Water disease in Japan is a typical case of mercury poisoning. 4. Other manifestations of the harm of waste batteries: At present, the treatment of domestic garbage in the world is mainly sanitary landfill, composting and incineration. The pollution of waste batteries mixed with domestic garbage in these three processes is reflected in landfill: the heavy metals of waste batteries pollute water and soil through infiltration. Incineration: waste batteries corrode equipment at high temperature, and some heavy metals volatilize in the fly ash of incinerator, causing air pollution; Heavy metals accumulate at the bottom of the incinerator, polluting the ash. Composting: The high content of heavy metals in waste batteries leads to the decline of compost quality. Reuse: reverberatory furnace metallurgy is generally used. Although the process is easy to master, the recovery rate is only 82%, and the rest lead appears in the form of gas and dust. At the same time, sulfur dioxide in the smelting process will enter the air, causing secondary pollution and directly endangering the health of operators.
