Application of Animal and Plant Combination Remediation Technology in Complex Heavy Metals Contaminated Soil

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.
