| 摘 要： | 研究了以撒施、撒施+草和穴施方式施用于赤红壤坡地上污泥中的Cu在人工降雨条件下随径流的迁移情况。结果表明,污泥撒施后的前期(1d和18d)径流中混匀样总Cu(MTCu)、静置样总Cu(STCu)、颗粒态总Cu(TPCu)、悬浮态总Cu(TSCu)和可溶性总Cu(TDCu)浓度和流失量均达到峰值,其中MTCu、STCu浓度和流失量峰值分别为1674.9μg·L-1、105.4μg·L-1和21.59mg·m-2、1.32mg·m-2,分别是穴施和撒施+草对应峰值的4.2～13.7倍和5.4～24.9倍;此后Cu浓度和流失量均逐渐降低。与撒施相比,撒施+草径流中各形态Cu浓度和流失量削减率可分别达72.8%～91.7%和91.4%～97.1%,穴施对应削减率则可分别达78.2%～89.9%和68.6%～82.9%。撒施、撒施+草和穴施MTCu径流流失系数分别为0.83%、0.03%和0.26%,穴施和撒施+草均可有效防止污泥Cu的流失,但以撒施+草效果最好。颗粒相Cu是Cu流失的重要形式。 |

| Abstract: | The effects of different application methods of sewage sludge on Cu transport by runoff from sloping plots in lateritic red soils were investigated under simulated rainfall conditions.When the sludge is broadcasted and mixed with surface soils,the concentrations and loss of MTCu (total Cu in mixed sample),STCu (total Cu in settled sample),TPCu (total particulate Cu),TSCu (total suspended Cu) and TDCu (total dissolved Cu) in runoff are highest on the 1 st and 18 th day after application.The peaks of concentr... |
