Abstract
The invention belongs to the field of oily sewage treatment and provides an oily sewage treatment system. The oily sewage treatment system comprises a sewage inlet, a dosing device, a coagulating sedimentation device, and a filtering and oil-water separating device, all of which are orderly connected with each other, wherein the dosing device and the coagulating sedimentation device are connected to an external filter press. Compared with an existing single treatment method, the oily sewage treatment system is capable of completely removing ions such as calcium and magnesium and suspended solids in the sewage and removing oily substances in the sewage by adopting physical-chemical-physical treatment steps; meanwhile, the generated solid impurities are squeezed into blocks by use of the filter press and convenient to transport; and in addition, the oily sewage treatment system has the advantages of simple equipment and easiness in operation, and the treated water is up to the emission standards.
Description
Technical field
The invention belongs to oily water treatment field.
Background technology
Oily(waste)water mainly comprises the oily(waste)water that other type in water (having another name called oil field extracted water), drilling waste water and station deviate from by crude oil.The process of oily(waste)water can have various ways according to the factor such as field produces, environment.When oil field needs water filling, oily(waste)water is reinjection into reservoir after treatment, now strictly will control the suspended substance in water, wet goods many index, prevents its formation from producing injury.If as the feedwater of vapour generator or boiler, then strictly to control the oil-contg etc. easily in the ion content of fouling, total mineralization and water such as calcium, magnesium etc. in water.If discharge after process, then according to local environment requirement, by sewage disposal to emission standard.Because oily(waste)water kind is many, the equal reason of stratum difference and drilling technology, each oily water treatment station not only water quality difference is large, and the change of water quality of oily(waste)water is large, and this is that the process of oily(waste)water brings difficulty.And each oil recovery factory is in arid substantially, water resources lacks area, how more effective process oily(waste)water, reaches protection of the environment, realizes the recycle of water resources, become that oily water treatment faces major issue.
Summary of the invention
The object of this invention is to provide a kind of oil-containing sewage treatment system, can process different sorts sewage, reach the effect that removal of impurities and oil removing remove simultaneously.
The present invention is achieved by the following technical programs: a kind of oil-containing sewage treatment system, and this system comprise connect successively sewage inlet, chemicals dosing plant, coagulant precipitation device, filtration and oily-water seperating equipment, the wherein external filter-pressing device of dosing coagulant precipitation device.
Described coagulant precipitation device comprises pipeline coagulation and buffering slurry tank.
Solid impurity outlet is provided with bottom described buffering slurry tank.
Described solid impurity outlet is connected with filter-pressing device.
Described chemicals dosing plant is positioned at pipeline coagulation device portal place.
Preferably, described filtration unit can be strainer or filter membrane, and described filter-pressing device is plate-and-frame filter press.
Preferably, described oily-water seperating equipment is water-and-oil separator, and described oily-water seperating equipment comprises reservoir chamber and accumulator, and described oily-water seperating equipment also comprises the sewage outlet be connected with reservoir chamber, and the sump oil be connected with accumulator exports.
The present invention has following beneficial effect:
Adopt physical-chemical-physical treatment step, not only completely except the impurity in decontaminated water, can also remove oily substance wherein, the impurity simultaneously after coagulant precipitation is squeezed into block by filter-pressing device, is convenient to focus on.
Accompanying drawing explanation
Below in conjunction with specific embodiment, the present invention will be further described.
Fig. 1 is oil-containing sewage treatment system schematic diagram provided by the invention.
In figure: 1. sewage inlet, 2. chemicals dosing plant, 3. pipeline coagulation device, 4. buffer-precipitation tank, 5. coagulant precipitation device, 6. plate-and-frame filter press, 7. filtration unit, 8. oily-water seperating equipment, 9. sump oil outlet, 10. sewage outlet.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the present invention is described further.
Embodiment: as shown in the figure, oily(waste)water by after sewage inlet 1 and the water conditioner that adds of chemicals dosing plant 2 fully react in pipeline coagulation device 3, clarification is placed in buffering slurry tank 4, reacted bottom impurity enters plate-and-frame filter press 6 by the impurities outlet bottom buffering slurry tank 4, impurity is squeezed into block, be convenient to collective conveyance process, after process, sewage enters filtration unit 7, ensure in the oily(waste)water after process without remaining levitation composition granule, enter oily-water seperating equipment 8 again, through oily water separation effect, sump oil is recycled by sump oil outlet, the waste water that sewage outlet is discharged can directly discharge or for other purposes.
oil-containing sewage treatment system described in the embodiment of the present invention can remove removing calcium magnesium plasma, suspended substance and oily substance, treatment types is many and often step process special emphasis is different, and process rear impurity is squeezed into block, is convenient to transport.
above content is the further description done the present invention in conjunction with concrete embodiment, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
