Description
Technical field
The utility model belongs to technical field of waste water processing, particularly a kind of oil-containing waste water treating device.
Background technology
Water pollution is one of main Environmental Problems that China faces.With China's industrial expansion, the discharge of industrial wastewater
Amount increasingly increases, be not achieved discharge standard industrial wastewater be discharged into water body after, can polluted surface water and underground water.Oily waste water comes
Source is extensive, complicated component.It is mainly derived from the Ministry of Industry such as oil, petrochemical industry, steel, coking, gas generating station, mechanical processing
Door.Oily waste water is discharged into river, lake or bay, and meeting polluted-water influences aquatile existence；For agricultural irrigation, then can
Interstices of soil is blocked, interferes crop growth.After oily waste water is discharged to the water bodys such as rivers,lakes and seas, the oil reservoir covering water surface prevents
Diffusion of the oxygen into water in air；Since dissolved oxygen is reduced in water body, the photosynthesis that algae carries out is restricted；It influences
The normal growth of aquatile makes aquatic animals and plants have oily taste or toxicity or even water body is made to foul, destroys the exploitation value of water resource
Value；If livestock has drunk oily waste water, it will usually infect fatal esophageal disease；If with oily waste water irrigated farmland, oil
And its mulching soil and the surface of plant are blocked the hole of soil by derivative, and air is prevented to penetrate, make fruit have oily taste or
Prevent soil that can cause crop production reduction or death when serious from being normally carried out metabolism and bacteria metabolism.In addition,
Due to the drift and diffusion of oil spilling, seabeach and seaside touring areas can be fallen into disuse, causes great environmental hazard and social danger.But more
Main harm is to be enriched with by fish, shellfish in oil and passed through food chain containing carcinogenic hydrocarbon to be detrimental to health.At present for oil-containing
Wastewater treatment is mostly using large scale equipment, and specific aim is not strong, and equipment investment and operation and maintenance cost are all very high, often equipment
Idle waste water, which is stolen, to be arranged, not only pollutional load that is uneconomical and increasing environment.
In the prior art, generally use oil separator separation oily waste water, oil separator are the difference of specific gravity using oil and water,
A kind of structures of the larger suspended oil of particle in separation removal waste water.A kind of oil separator as disclosed in 202729907 U of CN,
But since oily substance usually exists in waste water with three kinds of states：1. the particle that oil product disperses in waste water is larger, grain size is big
In 100 microns, it is easy to separate from waste water.2. the grain size very little that oil product disperses in waste water, in emulsified state, be not easy from
It is separated in waste water.3. fraction oil product is in dissolved state, separating difficulty is larger.And oil separator can only separate larger particles
Oily substance, this results in the inferior separating effect of oily substance in oily waste water, it is impossible to effectively remove the oil in oily waste water
Class substance.In order to fully be handled the oil in waste water, multiple equipment Combined Treatment is usually required at present, not only takes up an area face
Product is larger, and water-oil separating efficiency is low, and separating effect need to be improved.
