摘要: 采用生物堆模拟方法,研究苯并[a]芘(Bap)和二苯并[a,h]蒽(DBA)污染土壤的生物修复条件。结果表明,在生物堆投加绿肥或秸秆可明显促进BaP和DBA的降解;通气速率分别为0.05和0.10 m3·h-1时BaP和DBA的降解率无明显差异;添加EM菌对BaP和DBA的降解有抑制作用。在投加20 g·kg-1绿肥、通气速率为0.10 m3·h-1时,BaP和DBA的去除效果最佳,处理160 d时降解率分别达到64.8%和74.9%。

Abstract: Polycyclic aromatic hydrocarbons(PAHs) is very high in toxicity and very persistent in soil.It is,therefore,essential to study conditions for bio-remediation of benzo[a] pyrene(BaP) and dibenzo[a,h]anthracene(DBA) contaminated soils.It was found that addition of green manure or straw into the bio-pile significantly promoted the degradation of BaP and DBA;aeration from 0.05 to 0.10 m3·h-1 did not have any significant effect on their degradation;and the addition of EM actually inhibited their degradation;however,when the addition of green manure was set at 20 g·kg-1 and the aeration at 0.10 m3·h-1,the BaP and DBA degradation rate was the highest,reaching up to 64.8% and 74.9%,respectively after 160 days of incubation.

Key words: PAHs, remediation, contaminated soil, bio-pile
