| 摘 要： | 目的]研究棕壤和褐土在施入工业污泥和生活污泥后,土壤中各形态Cu、Zn、Pb、Cd的含量变化情况。方法]用污泥和土壤均匀混合的土柱来模拟实际土壤,对土柱进行7次淋洗后,测定土柱中0~10cm均匀混合层中各形态重金属的含量。结果]在施入工业污泥和生活污泥后,土壤中重金属根据形态不同而具有各自不同的变化规律。结论]重金属变化规律不仅与重金属各形态的迁移转化性质有关,还受污泥种类和土壤性质等多种因素的影响。 |
| 关 键 词： | 污泥农用 土壤 重金属形态 含量 |

| Abstract: | Objective] The aim of the research was to study mainly on the content changes of copper,zinc,lead and cadmium in soil after industrial sludge and living sludge applied to brunisolic and cinnamon soil.Method] In this study,soil column was used to replace the truely soil.The contents of all forms heavy metals had been determined in 0-10 cm evenly mixed soil layer after soil columns were leached for seven times.Result] The results showed that the contents of heavy metals changed in varying degrees according to different morphology of heavy metals.Conclusion] It was not noly related to the migration and transformation nature of heavy metal but also influenced by varieties of factors such as sludge category and soil properties. |
