Abstract
The invention discloses an oil wastewater treating apparatus, belonging to the field of oil processing equipment. The oil wastewater treating apparatus mainly comprises a high-efficiency shallow air-floating machine, a hydrolysis-acidification pool, a heating pool, an expanded granular sludge bed (EGSB), a contact oxidation pool, a secondary settling basin and a sludge thickener, wherein a grating is placed before the high-efficiency shallow air-floating machine; oil wastewater flows into the high-efficiency shallow air-floating machine via the grating; grating residues produced at the grating flows into a residue settling pool; the hydrolysis-acidification pool is located behind the high-efficiency shallow air-floating machine and successively connected with the heating pool, the EGSB, the contact oxidation pool and the secondary settling basin; wastewater treated by the secondary settling basin reaches the standard and is discharged; and sludge is discharged into the sludge thickener.
Description
Technical field
The present invention relates to fat and oil processing equipment, specially a kind of Fat wastewater treatment device.
Background technology
Substantial amounts of waste water is inevitably produced, due to also having many in waste water to ring in oil production
The material that border is harmful to, direct discharge can cause water pollution, and surrounding enviroment are polluted, therefore enterprise
Need strict process for producing fog, only meet the requirement of environmental protection just can be discharged.
The especially high sewage of oil content, in such sewage, not only the content of oil slick, oil emulsion and dissolved oil is high,
But also substantial amounts of suspended organic matter can be contaminated with, and usually can contain in above-mentioned suspended organic matter composition
The material of the degradabilities such as phenol, aldehyde, alcohol, alkane, halogenated hydrocarbons difference, therefore substantially increases oil content high
Wastewater treatment difficulty.
Content of the invention
The invention mainly solves the technical problem of providing a kind of Fat wastewater treatment device, it is mainly used in solving
Certainly the problems referred to above.
The present invention solves technical problem and adopts the following technical scheme that：
A kind of Fat wastewater treatment device is provided, its mainly include high-efficient shallow air flotation machine, hydrolysis acidification pool,
Heating bath, expanded granular sludge bed EGSB, contact-oxidation pool, secondary settling tank and sludge concentration tank, described
It is equipped with grid, oil wastewater flows in high-efficient shallow air flotation machine by grid, grid before high-efficient shallow air flotation machine
The grid slag that place produces flows into detritus tank, after described hydrolysis acidification pool is placed in high-efficient shallow air flotation machine, described hydrolysis
Acidification pool outlet connects heating bath, and described heating bath outlet connects expanded granular sludge bed EGSB, described expansion
Granular mud bed EGSB outlet connects contact-oxidation pool, and described contact-oxidation pool exports connecting secondary Sedimentation tank,
Discharged wastewater met the national standard after the process of described secondary settling tank, body refuse enters sludge concentration tank.Described detritus tank,
High-efficient shallow air flotation machine, hydrolysis acidification pool, expanded granular sludge bed EGSB carry out the body refuse of sewage disposal generation
It is discharged in sludge concentration tank；Blowing air in described contact-oxidation pool.
Preferably, the external sludge dewatering equipment of described sludge concentration tank, the body refuse after dehydration puts into body refuse treatment region
Domain is processed.
Compared with prior art its advantage is the present invention：Its process is simple, effect is good, percent of decolourization, oil
Dirty clearance is high, and COD, BOD clearance, tp removal rate are high, by first anaerobic reaction aerobic reaction again,
Make solid residues amount little and with low cost, be suitable for promoting.

Sedimentation tank, the discharged wastewater met the national standard after the process of described secondary settling tank, body refuse enters sludge concentration tank, described
The external sludge dewatering equipment of sludge concentration tank, the body refuse after dehydration is put into body refuse processing region and is processed.
For further optimisation technique scheme, described detritus tank, high-efficient shallow air flotation machine, hydrolysis acidification pool,
The body refuse that expanded granular sludge bed EGSB carries out sewage disposal generation is discharged in sludge concentration tank.
For further optimisation technique scheme, blowing air in described contact-oxidation pool.
Finally it should be noted that：The foregoing is only the preferred embodiments of the present invention, be not limited to
The present invention, although being described in detail to the present invention with reference to the foregoing embodiments, for the technology of this area
For personnel, it still can be modified to the technical scheme described in foregoing embodiments, or to it
Middle some technical characteristics carry out equivalent, all within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
