摘要
以台州重金属复合污染土壤为研究对象,通过大田试验方法,综合考察动植物联合修复技术在该复合污染土壤修复中的应用。结果表明:经过18个月的修复,土壤Cd、Cu、Pb含量分别降低92.3%,42.0%,24.7%。动植物联合修复效果优于单个动物修复和植物修复的简单叠加,其中Cd、Cu、Pb修复效果分别较单个动物修复和植物修复的简单叠加效果高11.5%,7.2%,5.0%,说明在重金属复合污染土壤修复中,该动植物联合修复技术是可行的,具有较强的推广应用前景。
A field experiment was carried out to survey the application of animal and plant combination remediation technology in local heavy metal contaminated soils.The results showed that,after 18months remediation,the content of Cd,Cu and Pb reduced by 92.3%,42.0% and 24.7%,respectively,which indicated that animal and plant combination remediation had better remediation effect than their simple added together,and the excess effect increased by 11.5%,7.2% and 5.0%,respectively.It＇s proved that animal and plant combination remediation technology was feasible for heavy metal contaminated soils and had strong application prospects.
