Abstract: With off-site bioremediation technolgy,a soil contaminated by crude oil from Liaohe Oil Field was treated on a 20×10m prepared bed.8 composting windrow units were set,each measured 8m in length,2m in width,and 0.35m in height.The results showed that when the pollutant petroleum hydrocarbon(TPH)was within the range of 4.16~7 72g·100g-1 soil,the total degradation rate of TPH reached 45.19%~56.74% after 53 days operation,which indicated that a technological basis would be provided for the bioremediation of oil-contaminated soil.

Key words: Petroleum contaminated soil, Windrow composting, Bioremediation
