Abstract
The invention belongs to the field of oilfield sewage treatment. The oilfield sewage treatment device comprises a sewage inlet, an oil separator, a chemical adding assembly, a coagulating and settling assembly, a primary filtering assembly, a secondary filtering assembly and a sewage outlet which are sequentially connected. Compared with a single treatment method, the treatment is more complete; through multi-stage filtration, other impurities and bacteria in oily sewage can be removed while oil is removed, without introducing other impurities; the oilfield sewage treatment device is simple, and easy to operate.
Description
Technical field
The invention belongs to field of oilfield sewage treatment.
Background technology
Oilfield sewage comparison of ingredients is complicated, oil content and oil existence form in water is not identical yet, and in most cases often mix mutually with other waste water, there is circumstance complication, usually exist with four kinds of states, floating oiling respectively, its oil droplet size is greater than 100um, is easy to be separated, dispersed oil, its particle diameter, between 10-100um, suspends in water.Oil in water emulsion, particle diameter is less than 10um, and the particle diameter disperseed in waste water is little to be not easily separated from waste water, dissolving oil, the state that oily substance is dissolved in the water, and is therefore difficult to remove completely.
Summary of the invention
The object of this invention is to provide a kind of oilfield sewage treatment device, can reach and remove sump oil in water completely.
The present invention is achieved by the following technical programs: a kind of oilfield sewage treatment device, and this device comprises the sewage inlet, oil trap, dosing assembly, coagulant precipitation assembly, single filter assembly, cascade filtration assembly and the sewage outlet that connect successively.
Described coagulant precipitation assembly comprises pipeline coagulation and buffering slurry tank.
Described single filter assembly is strainer or filter membrane.
Described cascade filtration assembly is ultrafiltration membrance filter or charcoal absorption.
Impurities outlet is provided with bottom described buffering slurry tank.
Described dosing assembly is positioned at coagulant precipitation module inlet place.
Described oil trap is provided with oil skimmer vessel.
The present invention has following beneficial effect:
Adopt physical-chemical-physical treatment step, can remove the oils in oily(waste)water completely, but not introduce other impurity, equipment is simple, easy handling.
Accompanying drawing explanation
Below in conjunction with specific embodiment, the present invention will be further described.
Fig. 1 is oil-contained waste water treatment device schematic diagram provided by the invention.
In figure: 1. sewage inlet, 2. oil trap, 3. dosing assembly, 4. coagulant precipitation assembly, 5. pipeline coagulation device, 6. cushion slurry tank, 7. single filter assembly, 8. cascade filtration assembly, 9. sewage outlet.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the present invention is described further.
Embodiment 1: as shown in Figure 1, oily(waste)water enters oil trap 2 by sewage inlet 1, remove its surperficial oil slick, the treatment agent that after process, sewage and dosing assembly 3 add fully reacts in pipeline coagulation device 5, clarification is placed in buffering slurry tank 6, reacted bottom impurity is discharged by the impurities outlet bottom buffering slurry tank 6, after process, sewage enters single filter assembly 7, in the present embodiment, single filter assembly 7 is strainer, to ensure to remove in waste water after oil in water emulsion and dispersed oil remaining levitation composition granule in oily(waste)water, oily(waste)water after single filter enters cascade filtration assembly 8, in the present embodiment, cascade filtration assembly 8 is ultrafiltration membrance filter, sewage after ultrafiltration is then discharged by sewage outlet 9.
oil-contained waste water treatment device described in the embodiment of the present invention thoroughly can be removed oily substance in oily(waste)water and suspended particle and not introduce other impurity, and equipment is simple, easy handling.
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.
