Industryization popularization and application have made it one of the tertiary oil recovery technology that recovery ratio is effectively improved in SHENGLI PETROLEUM AREA.But with polymer
The expansion in tertiary oil recovery scale is driven, the fresh water amount of oil field consumption is increasing, and compared with traditional handicraft, polymer flooding extraction is dirty
Not only contain a large amount of oils in water, also contains a large amount of polymer, such sewage viscosity is larger, and the increase of viscosity will increase in water
The stability of colloidal solid also increases the stability of Oil in Sewage Water class so that and water-oil separating difficulty increases, therefore, this kind of dirt
The intractability of water is also bigger than water drive conventional sewage intractability, the phenomenon that blocking filtrate containing poly- waste water generally occurs, this is significantly
Reduce the service efficiency of complete wastewater treatment equipment.For such polymer drive extraction sewage, degradation polymer reduces sewage
Viscosity, it is the key that sewage disposal to reduce water-oil separating difficulty.
The treatment technology of existing polymer drive extraction sewage is mainly chemical settling, bioflocculation, advanced oxidation etc., this
The shortcomings of it is larger that a little technologies correspond to that there is sludge quantities, and biologic packing material easily blocks, and operating cost is higher, and the processing unit disperseed
There is also taking up a large area, the problems such as larger is invested.Currently, it is less for the complete set of equipments of polymer displacement of reservoir oil extraction sewage, such as
A kind of oilfield chemistry flooding tertiary oil recovery recovered water microbial degradation of Chinese patent (103848543 B of publication number CN), advanced oxidation
Processing unit is mainly made of antimicrobial cell and advanced oxidation unit, after sewage is by microbial degradation, in high-frequency high-voltage
Active gases is generated to complete advanced oxidation using the oxygen in air under the action of.The advantages of equipment is rapid reaction effect
Fruit is good, the disadvantage is that filler clogging may easily be sent out.Such as a kind of coalescence of Chinese patent (102020336 A of publication number CN) and rotation
The integrated oil extraction waste water treatment device of flow separation and method, processing method are that oil extraction waste water is pumped to coalescence cylinder, dispersion
Mutually small oil droplet coalescence becomes larger, and enters form high-speed rotating vortex in hydrocyclone monomer therewith, heavy phase water is in underflow intracavitary
It collects, mutually oil is then forced toward axle center and is flowed to top lightweight, to achieve the effect that water-oil separating.The equipment mainly for
Oils, but it is unknown to the removal efficiency of polymer.Chinese patent (203593647 U of publication number CN) is a kind of to utilize chemical method
The reactor of oilfield sewage is handled, which is passed through acidic materials fully degraded organic matter by mechanism of making up a prescription, and makes oil field containing poly-
The COD value of sewage is down in allowable range；It is further acted on by electrocatalytic oxidation and generates the extremely strong hydroxyl radical free radical of oxidisability
And hypochlorous acid, promote polyacrylamide by further viscosity reduction chain rupture, resolves into the organic matter of small molecule.The advantages of reactor
It is that can implement at normal temperatures and pressures, high treating effect, the disadvantage is that not being suitable for the job requirement of continuous operation.
