Abstract
A kind of petrochemical industry oil-containing sewage treatment system, the elevator pump in wastewater disposal basin connect slagging-off oil interceptor by pipeline, and slagging-off oil interceptor passes through pipeline and connects one-level air-floating apparatus.Pipeline connection chemicals dosing plant between one-level air-floating apparatus and slagging-off oil interceptor, one-level air-floating apparatus connects secondary air-floatation device by pipeline, during secondary air-floatation device is connected by pipeline plus pond, the SBR elevator pumps of intermediate pool connect SBR biochemistry pools by pipeline, SBR biochemistry pools connect advanced treating pond by pipeline, advanced treating pond connects MBR biochemistry pools, MBR biochemistry pools connection production pond by pipeline.Petrochemical industry oil-containing sewage treatment system of the present utility model, by materialization and biochemical technology Combined Treatment oily waste water, good treatment effect can not only be obtained, the waste water after processing can be using reuse as general flushing water.
Description
Technical field
It the utility model is related to field of environmental engineering sewage treatment, more particularly to a kind of oil-containing sewage treatment system.
Background technology
Oily waste water is a kind of common industrial wastewater, and oily waste water occurs mainly with oil field and oil plant at present, regeneration
Caused a large amount of oily waste waters during production.The selection of oily wastewater treatment method and handling process and the composition of waste water and oil
The factors such as existing form are relevant.Although greasy dirt in the water of part can be decomposed and removed to single chemical treatment, may
The pollution of water body is caused, and removal oily in water is not thorough enough, it is difficult to meet processing requirement.And biochemical process is to oil content of intaking
It there are certain requirements.
Utility model content
In order to solve above mentioned problem existing for traditional oily sewage disposal, the utility model provides a kind of by materialization oil removing work
The petrochemical industry oil-containing sewage treatment system that skill is combined with secondary biochemical treatment technology.
Used technical scheme is the utility model to achieve the above object：A kind of petrochemical industry oil-containing sewage treatment system,
Elevator pump in wastewater disposal basin connects slagging-off oil interceptor by pipeline, and slagging-off oil interceptor connects one-level air-floating apparatus by pipeline.One
Pipeline connection chemicals dosing plant between level air-floating apparatus and slagging-off oil interceptor, one-level air-floating apparatus connect middle water by pipeline
Pond, the SBR elevator pumps of intermediate pool connect SBR biochemistry pools by pipeline, and SBR biochemistry pools connect advanced treating pond by pipeline,
Advanced treating pond connects MBR biochemistry pools, MBR biochemistry pools connection production pond by pipeline.
The one-level air-floating apparatus connects secondary air-floatation device by pipeline, and secondary air-floatation device adds in being connected by pipeline
Pond.
Petrochemical industry oil-containing sewage treatment system of the present utility model, by materialization and biochemical technology Combined Treatment oily waste water, no
It is only capable of obtaining good treatment effect, the waste water after processing can be using reuse as general flushing water.
Brief description of the drawings
Fig. 1 is the utility model petrochemical industry oil-containing sewage treatment system schematic diagram.
Embodiment
Oily sludge dewatering system of the present utility model as shown in figure 1, including：Wastewater disposal basin, slagging-off oil interceptor, one-level air supporting
Device, secondary air-floatation device, SBR biochemical devices, MBR biochemical devices, lifting water pump and chemicals dosing plant.Elevator pump in wastewater disposal basin
Slagging-off oil interceptor is connected by pipeline, slagging-off oil interceptor connects one-level air-floating apparatus by pipeline.One-level air-floating apparatus and slagging-off
Pipeline connection chemicals dosing plant between oil interceptor, one-level air-floating apparatus connect secondary air-floatation device, secondary air-floatation dress by pipeline
Put in being connected by pipeline plus pond, the SBR elevator pumps of intermediate pool connect SBR biochemistry pools by pipeline, SBR biochemistry pools pass through
Pipeline connection advanced treating pond, advanced treating pond connect MBR biochemistry pools, MBR biochemistry pools connection production pond by pipeline.
The course of work is as follows：
1）Oily waste water is collected in wastewater disposal basin first, then is quantitatively promoted to slagging-off oil interceptor by waste water lifting pump and is carried out in advance
Oil removing and slagging-off；
2）Oily waste water flow to one-level air-floating apparatus certainly after the oil removal that removes the gred, while according to inflow and oil content not
With the dosage of adjustment chemicals dosing plant.Medicament enters one-level air-floating apparatus after being mixed with oil-polluted water by blender and carries out oil-containing
The oil removing slagging-off of waste water；
3）In order to meet subsequent treatment requirement, one-level air supporting water outlet enters secondary air-floatation and carries out depth de-oiling, secondary air-floatation
Water outlet enters intermediate pool, enters SBR biochemical devices by elevator pump；
4）SBR bio-chemical effluents enter MBR biochemistry pools and carry out advanced treating, further reduce COD, NH3- N and suspension
Matter, reuse is contemplated that by the MBR production water handled.
