摘  要：
利用黑麦幼苗法测定了西安污水厂污泥施用于赤红壤中重金属总量、有效性以及重金属向地上部转移量的变化,探讨污泥施用于赤红壤的可能性。结果表明,黑麦幼苗吸收的重金属总量,Pb基本呈现稳定趋势,Cd、Cu、Zn呈上升趋势,而Ni呈下降趋势。除Pb外,其余4种重金属的吸收总量与污泥施用量之间均呈极显著相关。重金属有效性呈现Cd>Ni>Zn≈Cu>Pb的规律。总体上5种金属有效性均随污泥施入量的上升而下降,除Zn外,其余4种重金属的转移率均随污泥施用量的增大而上升。以上结果表明在赤红壤中施用污泥应该严格控制。

摘  要：
Possibility of applying sewage sludge produced from Xi ' an Sewage Treatment Plant on red soil has been studied by de-termining the HMB and heavy metal total amount changed with the amount of s ludge applied on red soil using rye se edling method.The results showed that total amount s of all Cd,Cu,Zn,absorbed by rye see dling increased,while the amount of Ni decreased with the increase of the amount of sewage s ludge applied on red soil exception o f that Pb had steady trend,and the amo unt of Cd,Cu,Zn and Ni had more significant correlation with the amount of sludge applied on the red soil.Additionally,from a spect of the results of HMB,the sequence of bioavailabilit y of five kinds of heavy metal determi ned by rye seedling were in an order:Cd>Ni>Zn≈Cu>Pb,and all of 5kinds heavy metals had a decreasing tread with the amount of sludge applied on red soil,while the transfer rate of Cd,Pb,Cu,Ni increased with the amount of sludge applied on red soil exceptio n of Zn.The results of study have indi cated that a strict control must be considered in applic ation of sludge on red soil.
