| 摘 要： | 以金华市污水处理厂污泥为研究对象,利用它对小白菜进行的盆栽试验,研究了以污泥作堆肥对土壤和小白菜重金属积累的影响.结果表明,随着污泥堆肥施用量的增加,土壤和小白菜地上部组织的Cu、Zn、Cd和Pb含量也呈积累趋势,当施用量为10%时,地上部组织的重金属含量超过国家食品卫生标准.由此说明,在污泥堆肥和利用过程中应进一步严格控制重金属及其在作物体中积累,尤其控制可食部分中重金属的含量和污泥堆肥长期施用过程中的重金属在土壤和作物中的积累.

| Abstract: | Sewage sludge of Jinhua city was analysed,pot experiment with Chinese cabbage was studied using sludge compost.The result showed that the content of heavy metals in soil and the top tissue of Chinese cabbage also increased remarkably,when using quantity 10%,an accumulation of Cu,Cd,Zn and Pb was observed with an increase in compost amendment.The content of heavy metals in the top tissue was higher than national criterion of food sanitation.This indicates that there should be a tight control for the use of t... |
