Abstract

The invention discloses an oily wastewater treatment device which comprises a wastewater collection tank, wherein a water inlet is formed in the side wall of the wastewater collection tank, and an oil baffle is arranged inside; an oil absorption pipe is arranged at the top of the wastewater collection tank and connected with an oil residue adsorption tank through an oil pump; filler is arranged at the bottom of the oil residue adsorption tank, and a slag outlet is formed in the side wall; the wastewater collection tank is connected with a sedimentation tank through a water pump 1; a residue outlet is formed at the bottom of the sedimentation tank; the sedimentation tank is connected with an anaerobic reaction tank through a water pump 2; an anaerobic bacteria carrier is arranged in the anaerobic reaction tank; the anaerobic reaction tank is connected with a clear water tank through a water pump 3; and a water outlet is formed in the side wall of the clear water tank. Compared with traditional technology, the device disclosed by the invention is scientific in design and simple in structure; and through treatment after oil-water separation, the treatment effect is perfect, and oil-water separation stage treatment is realized.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a treatment device for oily wastewater. Background technique [0002] Oily wastewater mainly includes oilfield wastewater, wastewater from refineries and petrochemical plants, ballast water, tank washing water, engine room water of oil tankers, cleaning water of oil tank (tank) vehicles, etc. Wastewater from gas plants and coking plants contains coal tar, and waste water from tanneries and food processing plants contains animal and vegetable oils. These are the main sources of environmental oil pollution. Oily wastewater is more difficult to treat, because oil and water are not completely immiscible, and oil in water is inevitable, which also brings great difficulty to the treatment. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to provide a treatment device for oily wastewater to address the deficiencies of th...
