化学-生物联合技术对重金属-有机物复合污染土壤的修复研究

Study on the Remediation of the Compound Polluted Soil by Heavy Metals and Organism by Using Chemical-biological Technologies

重金属-有机物复合污染是当今土壤污染中最普遍的一种,利用传统的化学修复法或现阶段比较盛行的各种生物修复法,如超积累植物富集修复、微生物降解修复等都难以对重金属-有机物复合污染土壤进行彻底治理修复。主要就利用化学-生物联合技术修复重金属-有机物复合污染土壤的反应机理以及修复中存在的问题进行研究探讨,并对该技术今后的发展方向进行展望。

The compound pollution of heavy metal and organism is one of the most widespread soil pollution at present.The compound polluted soil of heavy metals and organism could be controlled and remediated by using the traditional chemical remediation or various current popular biological remediation methods such as hyperaccumulators plant enrichment remediation,microbial degradation remediation.The reaction mechanism and existing problems in the remediation of heavy metals-organism combined polluted soil by using chemical-biological joint technique were studied and discussed.And the development direction of the technology in the future was predicted.
