Waste Battery Hazards

Waste Battery hazards
Battery products harmful to the environment are mainly acid, alkali and other electrolyte solution and heavy metal pollution. Pollutants in different types of batteries are also different.
In general, the battery of harmful substances are mainly Zn, Hg, CNi, Pb and other heavy metals; lead-acid batteries in the H2S04; a variety of alkaline batteries and lithium batteries KOH electrolyte, etc. IiPP6. Hg and its compounds, especially organic mercury compounds, has a strong biological toxicity, bioconcentration faster rate and a longer biological half-life of brain organs. Easy Cd accumulation in plants and animals in vivo, affecting the growth of plants and animals, are highly toxic. Pb on the person’s chest, kidney, reproductive, cardiovascular and other organs and systems have adversely affected the performance of mental decline, kidney damage, infertility and high blood pressure. Zn, Ni toxicity is relatively small, but more than a certain concentration range, would have adverse effects and harm the human body. Waste battery acid, alkaline hydrolysis would affect the quality of the soil solution, the pH value of water benefits, so that soil and water acidification or alkalization. Battery electrolyte composition of pollution is one of the major components of soluble heavy metals, particularly lead-acid batteries in a large number of sulfuric acid electrolyte lead and nickel-cadmium batteries cadmium hydroxide. Batteries of heavy metal ions dissolved in the soil or water the roots of plants and is absorbed, when the animals to plants as food-stuffs, the body will accumulate heavy metals. Human eating food containing heavy metals, vegetables and meat, water, along the food chain, heavy metal accumulation within the body would be. As the heavy metal ions in the body difficult to excrete, will eventually damage the nervous system and liver function.
Waste Battery Recycling Study
2.1 Waste Battery Recycling Status
Domestic use, most lead-acid battery industry battery, lead storage batteries accounted for more than 50% of the total cost, mainly in the fire, wet metallurgical processes, as well as solid-phase electro-reduction technology. The outer shell is plastic, can be regenerated, the basic realization of no secondary pollution.
Small secondary batteries are currently used by more nickel-cadmium, nickel hydrogen and lithium-ion batteries, nickel-cadmium batteries, cadmium is a strictly controlled environment, one of heavy metal elements, lithium-ion batteries in the organic electrolyte, nickel cadmium, nickel metal hydride battery The alkaline battery of supporting materials and manufacture of copper and other heavy metals, constitute environmental pollution. A small secondary battery current total is only hundreds of millions of domestic use only, and most of the smaller, low value waste batteries to use, coupled with the use of scattered, most for domestic waste disposal, there is the cost of their recovery and management of problem of recycling there are some technical problems.
