Study on enhanced bioremediation effect of oil-bearing dredging sediment

To solve the problem of difficult treatment oil-bearing dredging sediment, effects three methods microbial remediation, phytoremediation and combined bioremediation on oily river sediments were compared studied, influence factors remediation explored through static bacteria-fling tests. The results showed that method was better than single biological in treating bottom mud. oil content treated sediment 1.21g/kg, removal rate 95.31%; organic matter 72.30g/kg, degradation 37.33. %, which can meet requirements “ Control Standards Pollutants Sludge for Agricultural Use (GB4284–2018) ” be used agricultural purposes.
