When the utility model is used for treating oil field waste water, under the premise of ensuring that the quality of outlet water can reach the standers, various agents do not need additionally putting, the treating cost can be greatly reduced, the practical operating requirement on site is simplified, and the integration of floating oil removal and electrolytic sterilization is realized.
Description
Technical field
The utility model relates to wastewater treatment equipment, more particularly, is a kind of electric floating device of handling oil field waste.
Background technology
In oil-field development, oil field later stage particularly, the oil field will produce a large amount of recovered waters, for many years, the technology pattern of " oil removing section (oil removing ten secondary oil removings) ten fillter sections " is mainly adopted in domestic oil field to produced water disposal, wherein " oil removing section " adopts following method substantially: (1) physics method is primarily aimed at the oil slick in the former water; (2) chemical method mainly solves the dispersed oil in the former water; (3) coarse method is primarily aimed at the dispersed oil in the former water; (4) cyclonic separation method is mainly removed the oil slick in the former water; (5) air supporting method (air soluble method, revulsion) is mainly removed oil slick and dispersed oil in the former water.
Aforesaid method is obtained certain effect to the processing of the recovered water in each oil field, and is still along with the raising of injection water quality standard, more and more higher to the requirement of " oil removing section ", and the many weak points that exposed in the various treatment processs can not adapt to on-the-spot requirement.For example, the physics method only can be removed oil slick and the macrobead suspended substance in the former water, still need increase the secondary oil removal plant; Chemical method can only solve dispersed oil and the small granular suspended matters in the former water, and oil removal plant of front end is had relatively high expectations, and the factor that restricts the normal operation that adds pharmacy work simultaneously is more, is difficult to meet design requirement; The coarse method, higher to the import water quality requirement, the item for disposal effect is difficult to satisfy follow-up filtration unit requirement; The effect of cyclonic separation method removal suspended substance is relatively poor; Air supporting method (induce flotation, spray flotation), mechanical part is many, and energy consumption is higher, less stable, maintenance capacity is big.In addition, practice explanation for many years, " medicament adds " work whether normal is one of important factor that determines the produced water disposal effect, also is the lower where the shoe pinches of the long-term water quality reaching standard rate in each oil field.All need add various chemical medicaments in each treatment Technology for Petroleum Water Flooding at present, and at the scene in the actual mechanical process, be that screening, the dosage of medicament, the control that adds point, dosing method, cost, on-the-spot each link such as preparation all may influence treatment effect, make the water quality can not be up to standard.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes prior art, provides a kind of processing oil field waste electric floating device.
Treating oil field wastewater by electro-float process device of the present utility model is the horizontal circular container, inside is divided into pretreating zone and electric floating region, wherein pretreating zone comprises water inlet pipe and is welded on the container, down, two plate washers on the inwall and be welded in swash plate on two plate washers horizontal by 45～60 ° of angles, electric floating region comprises and being welded on respectively on the container, the plate washer of following inwall, be fixed on battery lead plate on the container inner wall with insulating material being provided with the bottom with the immediate plate washer of pretreating zone place, and container inner wall has been installed the effluent trough (pipe) of control water level effect before water outlet, and the container top of this external pretreating zone and electric floating region is welded with two and collects the oil slick oil-collecting bag that floats in the recovered water.
Described electrode materials comprises platinum electrode, Graphite Electrodes, the ferroelectric utmost point, aluminium electrode, preferably plates ruthenium titanium electrode, and the quantity of battery lead plate is relevant with unit scale and size of current, and the distance between the pole plate is 1-2cm.
Described swash plate material is that non-metallic material or stainless material are made.
Advantage of the present utility model and effect:
The utility model device can realize that electric floating oil removing and electrolytic sterilizing are integrated, and oil removal rate is greater than 90%, and the degerming rate is greater than 99%.According to the pneumatically supported principle of electricity: electric floating in the hydrogen gas bubbles diameter be generally 10-30 μ m, bubble diameter such as oxygen, chlorine is 20-60 μ m, microbubble has very high specific surface area, tiny oil droplets and suspended substance in can planar water, arrive several thousandths because the density of microbubble only be the hundreds of of the density of water, be easy to oil droplet and suspended substance be isolated water body and remove; Multiple strong oxidizing property materials such as anode produces oxygen, chlorine have stronger germicidal action, and chlorination is not realized the sterilization purpose.In oil field extracted water, on average at 4000-10 ten thousand mg/l, specific conductivity is bigger for salinity, uses electricly can regulate the relation that the pole piece spacing changes voltage and current density when floating, needn't add medicament again and regulate specific conductivity, has certain advantage during use; Use electric float method can remove suspended substance and oil slick, dispersed oil effectively, use flocculation agent or add flotation agent, can also remove dispersed oil and be partly dissolved oil; Owing to contain a large amount of chlorions in the recovered water, discharge a large amount of chlorine at electrode and reach the sterilization purpose, therefore the utility model can guarantee under the effluent quality prerequisite up to standard, solved " bottleneck " problem that each oil-field water of the restriction whole nation is handled, when realizing to add various medicaments in the wastewater treatment process, reduce processing cost significantly, simplified requirement execute-in-place.
