废旧电池掩埋处理方法初探

An Approach to Burying Disposal of Used Batteries

以分别种植小叶黄杨和八角金盘的2块试验土地与1块贫瘠裸露土地作为对照,试验植物吸收处理废旧电池的重金属污染的掩埋方法。文章介绍了将废旧电池内部的糊状物分别掩埋在小叶黄杨,八角金盘和贫瘠裸露土地3块试验土中,选用电池内部含量较多的 Zn 等重金属元素为跟踪元素,经一定时间后分析土壤中重金属元素的残留量。测定结果发现,小叶黄杨能很好地吸收掩埋入土的重金属元素,而八角金盘则对重金属没有明显的吸收作用。

Two pieces of experimental plots planted with Chinese littleleaf box （Buxus microphylla） and Fatsia japonica respectively plus another barren one as control plot were used for testing a burying disposal of abandoned batteries to handle the heavy metal contamination through the absorption by plants. After the interior paste of abandoned batteries had been buried into the soil of those three experimental plots respectively, the effects of absorbing heavy metals by plants were analysed by regularly detecting the residual contents of zinc and etc. that were usually abundant in batteries as tracers in the soil. The findings showed that Chinese littleleaf box could well absorb the elements of buried heavy metals whilst Fatsiajaponica could not do obviously.
