Activated carbon sewage treatment device and method

Abstract

The invention discloses an activated carbon sewage treatment device and a method thereof. The method is characterized by comprising the following steps of: S1, introducing waste emulsified wastewaterinto a grid filter for filtering, separating solid impurities, and discharging the obtained liquid into a wastewater purification tank for purification treatment, and S2, performing coagulation conditioning on the solid impurities in the step S1, discharging a mixed solution subjected to coagulation conditioning into a sludge dewatering machine for settling separation, and discharging a supernatant into an oil-water separator for oil-water separation to obtain an oily component. The problems that during recycling and reusing of the emulsified wastewater, molecular distillation is directly conducted on the emulsified wastewater after demulsification to purify the lubricating oil, heavy hydrocarbon in the waste emulsion waste liquid is not subjected to sufficient cyclic cracking, the obtained lubricating oil is small in amount and contains more impurities, and the recycling rate of the emulsified wastewater is affected are solved.

Description

Technical field

[0001] The invention belongs to the technical field of recovery methods for emulsified wastewater, and specifically relates to an activated carbon sewage treatment device and a method thereof. Background technique

[0002] In industrial production, there is a large amount of emulsified waste water, such as emulsified blood, some metal cutting liquids containing grease or a large amount of emulsified waste water in other industrial production, and the existing emulsified waste water Liquid treatment has certain defects in use. For example, when the emulsified wastewater is recycled and reused, the emulsified wastewater is demulsified and then directly subjected to molecular distillation to purify the lubricating oil, and the heavy hydrocarbons in the waste milk and waste liquid are not fully recycled and cracked The amount of lubricating oil obtained is less and contains more impurities, which affects the recovery and reuse rate of emulsified wastewater.
