Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] Such as figure 1 A combined multi-stage oil-water separation process shown, the specific steps are:

[0035] (1) Pretreatment: The oily sewage to be treated is transported to the self-cleaning filter by a sewage pump to remove mechanical impurities and suspended particles. Separator for primary separation;

[0036] (2) Primary separation: the filtered oily sewage enters the anti-pollution oil-water separator, and uses gravity to separate and gather the dispersed oil and floating oil. After separation, the light oil at the top and the heavy oil at the bottom are discharged and collected separately, and the oily sewage in the middle is sent to the Up to multi-stage high-precision oil-water separator for secondary separation, wherein the dirt-resistant oil-water separator includes tank body A 1, water inlet water device A 2 installed in t...

Abstract

The invention discloses a united multistage oil-water separation process. The united multistage oil-water separation process comprises the specific steps of 1 pretreatment, 2 primary separation and 3 secondary separation, wherein united multistage treatment is conducted on oily sewage by serially connecting a self-cleaning filter, a stain-resisting oil-water separator and a multistage high-precision oil-water separator, oil in oily sewage, especially dispersed oil, emulsified oil and the like, are rapidly separated in a pure physical mode, and oil recycling is achieved. The united multistage oil-water separation process comprises simple steps, is low in operating cost, good in operability and good in separation accuracy, can greatly improve the oil-water separation efficiency and effect and achieve recycling of various types of oil, can also produce remarkable economic benefits while achieving the environmental protection purpose and is suitable for industrialized application.

Description

technical field [0001] The present invention relates to the technical field of oil-water separation, in particular to a combined multi-purpose water treatment system for oily sewage such as coal-to-oil Fischer-Tropsch synthetic water, coal gasification sewage, semi-coke sewage, oil shale sewage, oily sewage from oilfields, and oily sewage from machining. advanced oil-water separation process. Background technique [0002] Oily wastewater is a common industrial wastewater. With the rapid development of the national economy, the amount of oily wastewater produced by many industries such as petroleum exploration, petroleum processing, and mechanical processing is also increasing. Oily sewage has the characteristics of many pollutant components and high concentration. [0003] Oil-water separation is the leader of the follow-up water treatment process, and its oil-water separation effect directly affects the operation effect and operation cost of the follow-up process. Most of...
