石油污染土壤长料堆式异位生物修复技术研究

An off site petroleum-contaminated soil bioremediation technology:soil composting in windrow.

应用长料堆式处理技术在长 2 0m、宽 10m的实用规模预制床上对辽河油田不同类型原油污染土壤进行了处理 .处理工程设 8个长条状堆料单元 ,每个堆料单元长 8m、宽 2m、高 0 .35m .当稀油、稠油和高凝油污染土壤中石油烃总量 (TPH)为 4.16～ 7.72 g·10 0 g-1土时 ,经过 5 3d的运行 ,TPH去除率 45 .19%～ 5 6 .74% .本研究为石油污染土壤异位生物修复实用化提供了技术支持 .

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.
