Problems solved by technology

[0002] In industrial production, a large amount of emulsified waste water is produced, such as emulsified cut blood, some oily metal cutting liquid or a large amount of emulsified waste water liquid in other industrial production, the existing emulsified waste water There are certain defects in the use of liquid treatment. For example, when the emulsified wastewater is recovered and reused, the emulsified wastewater is directly subjected to molecular distillation to purify lubricating oil after demulsification, and the heavy hydrocarbons in the waste milk and waste liquid are not sufficiently circulated and cracked. , the amount of lubricating oil obtained is less and contains more impurities, which affects the recovery and reuse rate of emulsified wastewater. It is difficult to make full use of the waste heat during thermal cracking, which affects the energy saving of the recovery and reuse of emulsified wastewater

Abstract

The invention discloses an activated carbon sewage treatment device and a method thereof, which is characterized in that it comprises the following steps: S1: introducing the waste emulsified waste water into a grid filter for filtration, separating solid impurities, and discharging the obtained liquid to waste water purification Sink for purification treatment; S2: Coagulate the solid impurities in step S1 for conditioning, discharge the mixed solution after coagulation conditioning to the sludge dewaterer for sedimentation and separation, and discharge the supernatant to the oil-water separator for oil-water separation , the oily components obtained; the present invention avoids the recovery and reuse of the emulsified wastewater liquid, and directly carries out molecular distillation to purify the lubricating oil after the emulsified wastewater liquid is demulsified, and the heavy hydrocarbons in the waste milk and waste liquid are not sufficiently circulated and cracked , The amount of lubricating oil obtained is less and contains more impurities, which affects the recovery of emulsified wastewater and the recovery rate of reuse.

Description

technical field [0001] The invention belongs to the technical field of the recovery method of emulsified waste water, and in particular relates to an activated carbon sewage treatment device and a method thereof. Background technique [0002] In industrial production, a large amount of emulsified wastewater is produced, such as emulsified cutting blood, some metal cutting liquid containing oil or other large amounts of emulsified wastewater in industrial production, existing emulsified wastewater There are certain defects in the use of liquid treatment. For example, when the emulsified wastewater is recovered and reused, the emulsified wastewater is demulsified and directly subjected to molecular distillation to purify the lubricating oil, and the heavy hydrocarbons in the waste emulsion are not fully recycled and cracked. The amount of the obtained lubricating oil is less and contains more impurities, which affects the recovery and reuse rate of the emulsified wastewater. ...
