| 摘 要： | 以草炭为生物基质,与陈化油泥按质量比1:1混合,采用现场土耕法研究草炭对陈化油泥强化生物降解的影响。经过26个月的现场试验,结果表明,草炭能显著提高陈化油泥的生物修复效果。陈化油泥中总石油烃(TPH)的降解率为38.9%;其理化性质得到显著改善,盐碱浓度显著降低(pH由8.7降至6.9,全盐量由20.3g/kg降至7.3g/kg),有机质浓度增加17.3%,有效态氮、有效态磷、有效态钾营养元素浓度显著增加;与陈化油泥自然衰减结果相比,草炭强化生物修复能提高微生物数量和生物的多样性。

| Abstract: | Peat was used as biosubstrate and mixed with aged oily sludge in the ratio of 1:1,and the field experiment was conducted to study the influence of peat on the bioremediation of aged oily sludge by landfarming.The results showed that after 26 months of field test,the bioremediation efficiency of aged oily sludge was significantly enhanced by adding peat,and the total petroleum hydrocarbons(TPH) of oily sludge was reduced by 38.9%.The physicochemical properties of oily sludge was obviously improved,the salini... |
