Assessment method ", experimental technique is as follows: access 1000 milliliters of water samples with 1000 milliliters of beakers, removes oil slick, then notes respectively
Enter in bottle 100ml trial jar, add a cover, number, put in the water bath with thermostatic control identical with sewerage temperature and preheat 15 minutes；
By predetermined chemical feeding quantity, sample is joined in trial jar, screw bottle cap, hand 200 times.Trial jar is put in water bath with thermostatic control, quiet
Putting a period of time, period observes water quality situation, oil pump capacity variation phenomenon, and record carries out water cleaning agent evaluation and screening.But have
A little oil fields are by air-floating apparatus process for producing water, and the principle of this device is: by adscititious gases, the microbubble of generation is by water
In little oil droplet take ullage to, make water quality become clear.So traditional experimental technique can not simulate air-floating apparatus carries out medicine
The screening of agent, have impact on water cleaning agent evaluation and the screening of applicable oil field air-floating apparatus, there is water cleaning agent usage amount inaccuracy, pin
The technical problem such as strong to property, clear water effect is bad.
Summary of the invention
The present invention solves technical problem present in known technology and provide the water cleaning agent of a kind of applicable oil field air-floating apparatus to comment
Valency method.
It is an object of the invention to provide one and have simple to operate, with strong points, the medicament screened by the method is suitable for
With air-floating apparatus with the use of, and then the water cleaning agent evaluation side of the applicable oil field air-floating apparatus of the feature such as the purpose reaching clear water
Method.
The present invention overcomes traditional water cleaning agent screening technique can not simulate the deficiency of air-floating apparatus, adds carbonic acid in experimentation
Calcium pressed powder and concentrated hydrochloric acid solution, utilize the bubble produced simulation air-floating apparatus to carry out the screening of water cleaning agent, pass through the method

The present invention is suitable for the water cleaning agent evaluation methodology of oil field air-floating apparatus and is adopted the technical scheme that:
The water cleaning agent evaluation methodology of a kind of applicable oil field air-floating apparatus, is characterized in: the water cleaning agent being suitable for oil field air-floating apparatus is commented
Valency process is: take oil field water sample, removes oil slick, is injected separately in experiment trial jar, adds a cover, numbers, put into and sewage
The water bath with thermostatic control that system temperature is identical preheats；Water cleaning agent sample is joined in trial jar, screws bottle cap, after shake, will examination
Bottle is put in water bath with thermostatic control；Then in each trial jar, add solid carbonic acid calcium powder, add concentrated hydrochloric acid, control number of bubbles,
Stand, observe water quality situation, it is achieved water cleaning agent evaluation.
The present invention is suitable for the water cleaning agent evaluation methodology of oil field air-floating apparatus and can also adopt the following technical scheme that
The water cleaning agent evaluation methodology of described applicable oil field air-floating apparatus, is characterized in: access oil field water sample with beaker, go
Except oil slick, it is injected separately in 50-250ml experiment trial jar, puts in the water bath with thermostatic control identical with sewerage temperature pre-
Hot 10-20min.
The water cleaning agent evaluation methodology of described applicable oil field air-floating apparatus, is characterized in: add 0.2-3g's in each trial jar
Solid carbonic acid calcium powder, adds the concentrated hydrochloric acid of 0.5-3ml bottom trial jar with pipet with a scale, stands 3-5min.
The present invention has the advantage that with good effect:
It is suitable for the technical scheme that the water cleaning agent evaluation methodology of oil field air-floating apparatus is brand-new owing to have employed the present invention, with prior art
Comparing, the water cleaning agent screening technique after present invention improvement can be simulated air-floating apparatus and be carried out the screening experiment of water cleaning agent, has behaviour
Make simple, with strong points, the medicament that screened by the method be suitable for air-floating apparatus with the use of, and then reach clear water
The advantage such as purpose.
Accompanying drawing explanation
Fig. 1 is experimental provision schematic diagram of the present invention.
In figure, 1-trial jar, 2-pipet, 3-calcium carbonate powder.
Detailed description of the invention
