Abstract An investigation was completed to determine the effects of petroleum contaminant aging in bioventing, a low cost and nondestructive in situ remediation method. Wet soil spiked with a known concentration of synthetic gasoline was aged in a refrigerator for 300 days and then subjected to degradation tests in 150 g respirometers and an 80 kg bioventing reactor. After aging, the 80 kg reactor had degradation rates that varied from to In the 150 g respirometer, the biodegradation rate increased from 0.079 to 0.194 Comparison with previously completed dry aged soils, where the biodegradation rate was measured to be 0.053 showed that microbial acclimatization during the wet aging process played a key factor in the experiments.

年龄对生物通风修复土壤中石油烃污染物的影响

摘要 完成了一项调查以确定石油污染物老化对生物通风的影响，这是一种低成本、无损的原位修复方法。掺入已知浓度合成汽油的湿土壤在冰箱中老化 300 天，然后在 150 克呼吸计和 80 公斤生物通风反应器中进行降解测试。老化后，80 kg 反应器的降解率从 到 150 g 呼吸计，生物降解率从 0.079 增加到 0.194 与之前完成的干燥老化土壤相比，生物降解率测量为 0.053 表明在湿老化过程在实验中起到了关键作用。
