植物-微生物联合修复石油-重金属复合污染土壤的研究

Study on Phyto-Microbial Remediation of Petroleum-Heavy Metals Contaminated Soil

植物及微生物联合修复石油-重金属复合污染土壤具有很大的潜力。但重金属以不同形态存在关系到石油-重金属复合污染土壤生物修复过程中,植物、微生物的修复效率以及是否需要增加辅助工程解决重金属污染等问题,因此石油-重金属复合污染土壤修复过程中就必须考虑重金属有效态及形态的变化特征。

It is proved that plant-microorganism combined bioremediation is a potential way to remediate contaminated soils with multiple pollutants of oil and heavy metals.However,the various existing forms of the heavy metals are vital to remediation efficiency and whether it is needed to increase the auxiliary project or not.Thus,the change of availability and forms of heavy metals during microbial remediation in petroleum-heavy metals contaminated soil should be investigated.
