降解菌ZQ5与紫茉莉对芘污染土壤的联合修复
Microbial-phytoremediation of pyrene contaminated soil using pyrene-degrading strain ZQ5 with Mirabilis Jalapa
摘要
Abstract
A pot-experiment in greenhouse was carried out to investigate the remediation efficiency of pyrene contaminated soil by planting Mirabilis Jalapa L alone,inoculating with PAHs-pyrene degrading bacteria ZQ5 strains alone and microbial-phytoremediation treatment.After 90 days,the results indicate that the microbial-phytoremediation has obvious superiority.It can remove 81.1％ pyrene in the artificially contaminated soil,and 50.3％ pyrene in the petroleum-contaminated soil.The microbial-phytoremediation efficiency is 1.98 times of Mirabilis Jalapa L and 1.39 times of ZQ5 strains.Different amounts of inoculating ZQ5 strains have obvious difference for initial repairment,but have little effect in the long-term repairment process.Under exogenous bioremediation conditions,the soil in depth of 10 cm to 20 cm has higher remediation efficiency than 5 cm; under natural degradation conditions,degradation rate of 5 cm depth soil is slightly higher than other soil.关键词
