  • 摘要: 对比研究了无机酸及超声对猪粪中重金属Cu、Zn和Mn的去除效果,并对处理前后猪粪中重金属形态变化进行分析。结果表明:无机酸浸提优化条件下Cu、Zn和Mn的浸出率分别为43.24%、76.28%和78.91%；超声协同无机酸浸提优化条件下Cu、Zn和Mn的浸出率分别为39.6%、76.3%和79.9%；2种浸提方式均能显著降低猪粪中重金属有机结合态含量。
    Abstract: This paper studied the removal effects of the inorganic acid and ultrasound on heavy metals Cu, Zn and Mn from pig manure, and changes in fractions of these heavy metals in pig manure before and after the extraction. In general, for the inorganic acid, the removal efficiencies of Cu, Zn and Mn reached 43.24%, 76.28%, 78.91% and for the ultrasound-assisted inorganic acid, the removal efficiencies of Cu, Zn and Mn reached 39.6%,76.3%,79.9% under the optimal conditions. Two kinds of extraction methods can significantly reduce organic matter fraction of heavy metals.
