Oily Sludge Biological/Electrochemical Coupling Process In Pilot Studies

In the oil field development and production process, it will generate a lot of oily sludge, including bottom sludge, construction operations landing oily sludge, and so on. With the development of oil field development and production, oily sludge is increasing. Because the sludge containing sulphide, BTEX, phenols, anthracene, pyrene and other foul-smelling toxic and hazardous substances, as well as crude oil, the environmental pollution is getting worse. Now the oily sludge which was pretreated in Daqing oilfield still cannot be Innocuous and recycle of resources. So the advanced treatment was necessary.This paper intended to explore for a kind of depth, harmless disposal of oily sludge process, by applying an electric field to the oily sludge, to stimulate the indigenous microorganisms and exogenous microorganisms to improve indigenous microorganisms and exogenous microbial oil degradation rate. Proposed an electrochemical-biological coupling an in-depth treatment of oily sludge technology, and its feasibility and advantages and disadvantages.
