Problems solved by technology

[0004] Traditional gravity separation oil separation facilities are usually single separation oil separation facilities, and most of them are advection type oil separation tanks or single inclined plate type oil separation tanks, which are mainly used to separate floating oil and disperse oily light oil substances; for heavy oil Oil separation and recovery of similar substances are often additionally treated by adding separate treatment facilities. At the same time, the oil floating on the upper layer of the gravity separation oil separation facility often needs to be cleaned manually, the equipment operation intensity is high, and the oil removal efficiency is low; at the same time, the traditional oil separation facilities The treatment of light oil is usually carried out by flocculation reaction precipitation and oil separation and oil removal, which is not conducive to green circular economy
[0005] Traditional oil separation facilities and oil storage facilities are often independent and split facilities with scattered layout, large total area and low land utilization rate

Embodiment Construction

[0041] Such as Figure 1-7 As shown, a schematic diagram of a new type of oil separation combined equipment is provided for the technical solution of the patent of the present invention.

[0042] The sewage produced by an enterprise contains a large amount of heavy oil, slick oil, and partially dispersed light oil substances. If the oil substances enter the subsequent biochemical treatment system without treatment, they will adhere to the surface of the activated sludge and inhibit the growth of microorganisms in the biochemical treatment unit. Normal growth will directly affect the operation of the biochemical system. In severe cases, it will destroy the sludge activity of the activated sludge system and affect the effect of biochemical treatment. Oil separation pretreatment is required for this oily sewage.

[0043] The equipment includes four unit parts: primary oil separation and recovery chamber 27, secondary oil separation and recovery chamber 28, oil collection chamber ...

Abstract

The invention relates to a sewage treatment apparatus, particularly an oil-separation recovery combination apparatus capable of simultaneously recovering heavy oil and light oil. A primary oil-separation recovery heavy oil apparatus, a secondary oil-separation recovery light oil apparatus, an oil collection apparatus and the like are combined into a serial modular combination apparatus, and all the apparatuses are separated by partitions. The oil-separation recovery combination apparatus can simultaneously recover heavy oil, floating oil and partial dispersed light oil substances in sewage, and is beneficial to green circular economy.

Description

technical field [0001] The patent of the present invention relates to a sewage treatment equipment, in particular to an oil separation recovery combined equipment capable of recovering heavy oil and light oil at the same time. Background technique [0002] At present, some organic pollutants in industrial oily sewage often exist in the sewage in the oil phase. These oily substances exist in the form of heavy oil, slick oil, and dispersed oil to a large extent. If the treatment effect of this oily substance is Not good, it is often very easy to affect the subsequent sewage treatment process. [0003] Gravity separation of heavy oil, slick oil and dispersed oil light oil is the most widely used and practical oily sewage treatment process. This method can be used to recover slick oil, partially dispersed oil light oil and heavy oil in sewage. [0004] Traditional gravity separation oil separation facilities are usually single separation oil separation facilities, and most of t...
