Abstract
The invention discloses a process for treating sewage generated during oil processing. The process comprises the following steps that the sewage is fed into a separation tank to undergo mechanical oil separation and reagent feeding treatment; floating oil separated from the separation tank is conveyed to a soap workshop for further processing; the sewage separated from the separation tank is conveyed to a sedimentation tank through a trough for sedimentation and water-slurry separation; the deposited sewage is conveyed to an anaerobic tank for biological aeration; after biological aeration treatment inside the anaerobic tank, the sewage is conveyed to a filtering basin to be filtered; then, the filtered up-to-the-standard water is conveyed to a clean water tank for further use; and finally, slurry inside the anaerobic tank and the filtering basin and slurry inside the sedimentation tank are conveyed to a compression forming machine be made into cakes through compression. The sewage treated by the process meets national primary standards on water quality, and can be directly recycled; therefore, more than 70 percent of water can be saved during the whole production process; moreover, the process can save power by 40 to 50KW and reduce charges for sewage treatment from 3 yuan/m3 to 1.6 yuan/m3.
Description
Technical field
The present invention relates to sewage treatment process, directly relate to the sewage treatment process of oil processing industry.
Background technology
The anaerobic process sewage treatment process is still the technology that current enterprise pollution treatment emphasis is chosen, the basic technology route of this technology is: at first sewage is squeezed into two with pump and handle to the dosing of third order reaction jar, again sewage is sent into suction pit clarification and precipitation, enter anaerobic pond then and slough N, P, COD, send into filter at last and filter.This technology wide accommodation, offset N, the P and the COD that remove in the sewage effect is preferably arranged, it is not pointed that yet this technology is in use found oil processing industry, uses this technology also to exist the deficiency that water consumption is big, power consumption is high, residual oil slick can't be handled at oil processing industry.
Summary of the invention
Purpose of the present invention will provide a kind of improved lipin processing sewage disposal process exactly, and it can overcome existing general anaerobism sewage treatment process effectively and be applied to the deficiency that water consumption is big, power consumption is high, residual oil slick can't be handled that oil processing industry exists.
The object of the present invention is achieved like this, and lipin processing sewage disposal process has following process steps: a, sewage is squeezed into oil trap carry out that the mechanical type greasy dirt separates and dosing is handled; B, collect to send into next procedure and carry out soap series products processing from the oil slick that oil trap is separated; C, the sewage that will separate from oil trap are sent into the settling tank precipitation by tank and water, slurry are separated; D, will send into anaerobic pond through the sewage that precipitated and carry out the sudden and violent gas of biology, remove N, P, COD composition; E, will send into filtering basin through the sewage of the sudden and violent gas disposal of biology from anaerobic pond and filter; F, that filtered water up to standard is sent into clean water basin is standby; G, will from the mud of anaerobic pond, filtering basin with together squeeze into compacting shape machine compression system cake from the mud of settling tank.
As further scheme of the present invention, the sewage in the oil trap with the preliminary sudden and violent gas of sudden and violent mechanism of qi, is used stirrer and separated the scraper plate separation the greasy dirt in the oil trap.
As further scheme of the present invention, described settling tank, anaerobic pond, filtering basin are secondary.
As further again scheme of the present invention, the mud of autoprecipitation pond, anaerobic pond, filtering basin is sent into the compacting shape machine compressed moulding with spiral pump in the future.
The present invention is owing at first squeeze into sewage the oil trap that greasy dirt separates and the dosing processing is shared in technology, thereby compare with traditional technology and both to have saved two to the third order reaction jar, shortened technical process, make greasy dirt obtain in advance separating, disposing of sewage for next procedure and created convenience again; The present invention is because greasy dirt separation circuit in oil trap is a mechanical type separates, thereby do not disturb mutually with adding drug treating sewage, and isolated oil slick also can be used as the raw material of soap series products processing simultaneously, has fully recycled the resource in the sewage; The present invention be directed to the custom-designed technology of oils industry, owing in technology, adopted the isolating operation of greasy dirt, water after the processing has been removed oil content, sewage by art breading of the present invention meets country-level water quality standard, can directly recycle, thereby the water consumption in the whole process of production can reduce greatly, but water saving is more than 70%; The present invention has been owing to replaced two in the traditional technology to the third order reaction jar with oil trap, and filter in the traditional technology is replaced with filtering basin, can lean on the waterhead gravity flow to realize filtering simultaneously, thereby can save power 40-50KW; Adopt the present invention, press flow dosing gradually, concentrate in general export and observe, detect water sample owing to can concentrate in oil trap, with respect to each jar dosing respectively, observe and detection has not only been saved manpower but also reduced labour intensity; Adopt the sewage of art breading grease of the present invention enterprise, expense can be reduced to 1.6 yuan/cubic metre from 3 yuan/cubic metre.Oil trap treatment process among the present invention also can be removed the part N in the sewage, P after adopting mechanical aeration in advance, and making in the sewage treatment process towards periphery, the degree of environmental emission bad smell greatly reduces.
Description of drawings
Accompanying drawing is a process flow diagram of the present invention, and the invention will be further described below in conjunction with accompanying drawing.
Embodiment
Accompanying drawing shows the flow process of lipin processing sewage disposal process of the present invention, at first sewage is squeezed into oil trap and carried out separation of mechanical type greasy dirt and dosing processing, the separation machinery that is adopted is selected stirrer for use and is separated scraper plate, used stirrer is preferentially selected separating centrifuge for use, meanwhile to the sewage in the oil trap with the preliminary sudden and violent gas of sudden and violent mechanism of qi, the oil slick that oil trap is separated is sent into next procedure and is carried out soap series products processing again, the sewage of separating from oil trap is sent into the settling tank precipitation by tank and with water, slurry separates, to send into anaerobic pond through the sewage that precipitated then and carry out the sudden and violent gas of biology, remove N, P, the COD composition, to send into filtering basin through the sewage of the sudden and violent gas disposal of biology from anaerobic pond subsequently and filter, it is standby at last filtered water up to standard to be sent into clean water basin.With the carrying out of sewage treatment process, also together squeeze into compacting shape machine compression system cake from the mud of anaerobic pond, filtering basin and from the mud of settling tank.Described settling tank, anaerobic pond, filtering basin are all preferentially selected secondary for use.Preferentially selecting for use spiral pump to send into the compacting shape machine compressed moulding from the mud of settling tank, anaerobic pond, filtering basin is the mud cake that contains N, P, and the mud cake can be used as fertilizer and takes out.
