摘要: 采用预制床生物修复技术首次对江苏油田3个井站的罐底油泥(砂)和三相分离器废油泥(砂)进行工艺研究,建立了运行稳定的处理与利用现场示范工程,取得了满意的试验效果,现场油泥(砂)的总油含量>100 g/kg(土),装置运行2个月,总油去除率96.4%~98.4%,其中烷烃去除率74.7%~98.5%,沥青质去除率75.0%~89.4%,芳香烃去除率85.5%~99.6%。Abstract: The bioremediation technique with preparate bed was firstly used for the treatment of oily sludge from tank bottom or three phase separators in Jiangsu Oil Exploration Company.The experimental results show that when the total oil content of the sludge was less than 100 g/kg and the experiment was carried on for two months,the removal rates of total oil,alkane,bitumen,and aromatic compounds were 96.4%~98.4%,74.7%~98.5%,75.4%~89.4% and 85.5%~99.6%,respectively.
