Bioreactor keeps hydrocarbons biodegradable by artificially controlling the operating conditions such as oxygenation, temperature, nutriment.
Solvent extraction: oily substance in sludge by solvent drawer after being come out, by distilling solvent from mixture
Separate recycling.
Wastewater Treatment Field in Refinery oil soil treatment technique: greasy filth is subjected to thickening, then by adding a certain amount of flocculation
Agent improves its dewatering, then carries out mechanical dehydration.
As the cold burnt medium method of coking after grease extraction and separation: sump oil and greasy filth make after heating up in slop tank oil,
Water and mud three phase separation carry out cutting water again, cut remaining sump oil and greasy filth after water and settle through greasy filth pond, bottom of pond residue greasy filth enters
It send after gravity concentration tank concentration to coking plant, hot coke is cooled down before coke cleaning as quenching medium, is separated in greasy filth
Water out can be used as coke cooling water or coke cutting water reuse.
Delayed coking steams out greatly facture: a kind of oil plant three-level model and the combined recovery device to steam out greatly will refine oil
The dross of enterprise after steam atomization, from coke drum bottom carry out coke drum in, to oil plant generate aqueous oily waste residue into
Row harmless treatment.

Compared with prior art, the utility model has the following beneficial effects:
(1) coking plant coke drum is utilized in a large amount of surplus heats in stage of steaming out greatly in the utility model, contains to oil-containing
Water waste residue is handled, and does not need to be additionally provided the media such as heat or steam, processing cost is lower, high treating effect.
(2) compared with the delay coking process of unused waste residue spray, existed using processing system provided by the utility model
It is conventional steam out greatly operation when the quantity of steam that consumes reduce 50% or more.It is sprayed simultaneously using from the top and bottom of coking plant
The design for drenching waste residue, compared with bottom atomising device is used only, Solid state fermentation amount increases 30% or more, and adds the useless of top
After slag spray spout, focusing layer of charcoal plays the effect of washing, prevents in Solid state fermentation, steam brings solid slag into oil gas
Pipeline and contact cooling tower, lead to oil-gas pipeline coking.
