【摘要】 所有的家用干电池中都或多或少含有不同种类的重金属。这些重金属进入环境并达到一定含量后 ,其毒性对人体健康和生物圈会造成潜在危害。而电池进入填埋场后是否会发生壳体破损并造成重金属污染 ?本文针对废干电池进入填埋场后 ,重金属的释放和污染情况进行了试验研究。结果表明 ,电池壳体可有效阻止电池中重金属的释放 ,即便是在破损后对渗滤液中重金属的贡献也是微乎其微的。更多还原

【Abstract】 Heavy metals are present at different concentrations in all the household dry batteries. Heavy metals included are toxic and thus maybe exert health and ecological risks to the population and the biosphere around landfill sites. Is it true that the shell will break and the heave metals will run out of the shell after the battery enters into the landfill? The release and the contamination of heavy metals were studied in this paper. It is shown that the shell could effectively prevent the release of the heavy metals, even after the breakage of the shell, and the amounts of the heavy metals in the leachate from battery are very low.更多还原
