Green Remediation Technology for Total Petroleum Hydrocarbon-Contaminated Soil
In order to improve the bioremediation efficiency of petroleum-contaminated soil, five test groups were selected in this study, including native bacteria, <i>Acinetobacter venetianus</i>, <i>Vetiveria zizanioides</i> L., and <i>Vetiveria zizanioides</i> L. combine...

| description | In order to improve the bioremediation efficiency of petroleum-contaminated soil, five test groups were selected in this study, including native bacteria, <i>Acinetobacter venetianus</i>, <i>Vetiveria zizanioides</i> L., and <i>Vetiveria zizanioides</i> L. combined with <i>Acinetobacter venetianus</i> and biochar to compare the degradation efficiency of petroleum-contaminated soil. The results of the study showed that after a six-month bioremediation, there was no significant difference between the native bacteria and the A.V. bacteria group in the removal efficiency of TPH, and the proportion of degradable TPH accounts for about 50~70%. The removal efficiency of TPH could be increased by 18.1–29% by increasing the phytoremediation of <i>Vetiveria zizanioides</i> L. The cultivation of <i>Vetiveria zizanioides</i> L. could not only stabilize the soil’s pH and conductivity but could also increase the soil’s bacterial abundance. It was suggested that bioremediation could be carried out through the combination of native bacteria and the planting of <i>Vetiveria zizanioides</i> L. Although the addition of biochar to the soil was able to improve the remediation effect of <i>Vetiveria zizanioides</i> L., it would increase the soil conductivity and reduce the abundance of soil bacteria. Therefore, it was recommended to reduce the conductivity of biochar before adding it, which may improve processing efficiency. |
