预制床技术在油泥(砂)处理中的应用

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.
