| 摘 要： | 在猪粪混合堆肥中，采用不同的通风方式和填充料，分析该过程中重金属总量和DTPA提取的重金属含量变化。结果表明，通过猪粪混合堆肥，重金属总量不会降低，但重金属生物有效性可降低；在猪粪与木屑混合堆肥中，加入树叶或鸡粪均能显著降低重金属的生物有效性，强制通风 机械翻堆比单一机械翻堆更能降低重金属的生物有效性。

| Abstract: | The trend in total contents of heavy metals and the assimilable heavy metals in pig manure composting of using different bulking agents and aeration modes have been analyzed. The result shows obviously that pig manure composting cannot reduce the total heavy metals but do decrease the portion of the assimilable heavy metals; adding chicken manure or tree leaves can decrease the portion of the assimilable heavy metals during the composting of pig manure with sawdust; and effect of the forced aeration combined with mechanical turning is better than that of the only mechanical turning also. |
