The invention relates to a device used for treating oily sewage, belonging to the technical field of sewage treatment. The device used for treating oily sewage is characterized by comprising an adjusting tank, a hydrolysis acidification tank, a nitrification tank, a sedimentation tank, a membrane bio-reactor (MBR) tank and a water production tank, wherein the adjusting tank is communicated with the hydrolysis acidification tank; the hydrolysis acidification tank is communicated with the nitrification tank; the nitrification tank is communicated with the sedimentation tank; the sedimentation tank is communicated with the MBR tank; the MBR tank is communicated with the water production tank by a self-priming pump; the adjusting tank is provided with a coagulant feeding mechanism and a flocculant feeding mechanism; both the adjusting tank and the nitrification tank are provided with aerating devices; the bottom end of the sedimentation tank is communicated with a mud storage tank; the mud storage tank is connected with a blow-down pump to carry out blow-down treatment. The device has the advantages of simple structure, small floor area, convenience in operation and maintenance, good treatment effect, good effluent quality, low sludge treatment cost, energy conservation, environment friendliness, high work efficiency and the like.
Description
technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a device for treating oily sewage. Background technique [0002] At present, with the acceleration of oilfield development process, oilfield sewage is increasing day by day, seriously polluting the ecological environment. Oilfield wastewater is complex in quality, containing petroleum demulsifiers, salts, phenols, sulfur and other environmental pollutants. Oilfield sewage generally has the following characteristics: high oil content (1000mg / L); high salinity (20000-50000mg / L); pH value is alkaline (7.5-8.5); sewage contains bacteria (sulfate reducing bacteria), etc. Oilfield sewage mainly includes crude oil effluent, drilling sewage and other types of oily sewage in the station. Existing sewage treatment devices of this type have complex structures, high operating costs, and low treatment efficiency; if they are directly discharged without treatment, they will directly...
