多环芳烃污染土壤微生物修复技术

Research Advance on the Bioremediation of PAHs Contaminated Soil

微生物降解是环境中PAHs主要的降解方式。介绍了微生物的降解能力、PAHs生物可利用性、电子受体、营养物质、环境因子及植物联合等对微生物降解PAHs的影响,并且对原位处理、异位处理的修复工艺进行了简述。同时,指出今后的治理应重视污染源头控制,完善酶制剂、联合修复等有效的生物修复技术。

Microbial degradation is the major degradation process of PAHs in the environment.Influence of microbes biodegradation property,bioavailability,electron acceptor,nutrient,environmental factors,and plant to biodegradation of PAHs and the remediation technology,including in-situ and off site remediation,were introduced.Controlling the pollution source,enzyme remediation and combined remediation were recommended in the remediation process.
