Abstract

The invention discloses a device for treating oil dirt in sewage with a rotational flow method and a removal method of the oil dirt in sewage with rotational flow method. The device is composed of a sewage tank, a water conveying device, an oil removing and precipitation tank, a rotational flow oil collection device, a clean water discharging pipe, an oil dirt discharging pipe, a sludge discharging pipe, a sludge tank, a bracket and a control system, wherein sewage enters the oil removing and precipitation tank from the bottom through the water conveying device; treated clean water is discharged out of a tank body through the clean water discharging pipe; the oil dirt is discharged out of the tank body through the oil dirt discharging pipe; and impurities are discharged into the sludge tank through the sludge discharging pipe. The device for treating oil dirt in sewage with the rotational flow method and the removal method of the oil dirt, disclosed by the invention, have the advantages of novel and reasonable structure, high oil dirt removing rate and wide applicable range.

Description

technical field [0001] The invention belongs to the field of sewage treatment devices, and in particular relates to a device for treating oil in sewage by a cyclone method and a removal method thereof. Background technique [0002] A large amount of oily sewage is produced in the process of oil and gas fields and petrochemical production. The oily sewage contains crude oil, suspended solids and other complex mineral impurities, which must be treated. Direct discharge will pollute the environment, and direct reinjection will cause formation pollution. [0003] In the existing technology, in order to remove crude oil and suspended solids in oily sewage, oily sewage in oil and gas fields is usually completed by vertical gravity deoiling tanks and vertical coagulation settling tanks, while oily sewage in petrochemical The oil separation sedimentation tank is completed; the follow-up generally adopts inclined plate oil separation or air flotation, coarse granulation and multi-med...
