Description
Technical field
The utility model belongs to the process field of oil gas field waste water, and the oil gas field waste water of especially a kind of no settling system is deep
Spend processing system.
Background technique
It increases, gradually increases to recovery well quantity, oil gas field waste water also gradually increases with national exploration of oil and gas field dynamics
More, oil gas field waste water has also dissolved into solubility salt, suspended matter, pernicious gas, organic matter etc., this external-open in addition to containing petroleum-type
It is also possible to artificially add the various additives such as fracturing fluid during adopting, so oil gas field Petroleum Wastewater content reaches 100
~500mg/L, petroleum-type are partially emulsification state based on existing with suspended state, and emulsification oil distribution stabilization is not readily separated.Oil gas field is useless
Water COD is substantially between 800~3000mg/L, and there may be a certain amount of cyclic aromatic compounds analog derivative in waste water, property is stablized, no
Easily it is oxidized removal.Suspended particulate is small in waste water, SS content is high, and SS is 300~2000mg/L.Salinity is high, contains a variety of salt
Class, every liter of waste water chlorine ion concentration can reach tens of thousands of or even ten tens of thousands of milligrams.These features determine that oil gas field waste water cannot be straight
Run in and be put into environment, it is necessary to deal carefully with, oil gas field waste water treatment technique mainly has re-injection, recycling reuse and processing at present
Three kinds of standard discharge, common processing unit such as attached drawing 1: sewage enters electrocatalytic oxidation after conditioning tank adjusts soda acid and water quality
System breaks after glue removes a large amount of COD in catalytic oxidation system and enters flocculation unit.After flocculation waste water enter inclined-plate clarifying basin into
Row mud-water separation, water outlet is filtered off through more medium filter and active carbon further removes oil removal and colloidal substance, active carbon
Filter entered RO system after being discharged cartridge filter.There are following Railway Projects for the process oil gas field waste water:
1, process chemistry treatment agent dosage is big, introduces high volence metal ion, brings secondary pollution and influences resource
Change and utilizes；
2, treatment process is longer, and stability is poor, since the floc sludge amount after agent-feeding treatment is big, increases to be separated by solid-liquid separation and bear
Lotus；
3, it is taken up a large area in technique using conventional approach such as sedimentation basins, low separation efficiency, it is difficult to skid, it is subsequent also to need
Suspended matter and colloid in sewage are further removed through more medium filter and active carbon filter, is checked on for feed water by reverse osmosis.
Summary of the invention
In view of the above shortcomings of the prior art, a kind of oil gas field of no settling system provided by the utility model is waste water advanced
Processing unit, including former pond, conditioning tank, electrocatalytic oxidation system, except hard pond, flocculation basin, tubular ultra-filtration membrane system, caching
Pond, RO system, equipment for separating liquid from solid；Sewage inlet pipe formula ultrafiltration membrane system in the cache pool, it is concentrated after dope return
It is flow to cache pool, part dope drains into solid-liquid separating device, and the separating liquid of equipment for separating liquid from solid is back to conditioning tank, and water outlet enters RO
System；The cache pool is equipped with water inlet, water outlet, refluxing opening and dope mouth；Boring aeration device is equipped in the conditioning tank,
Except blender is mixed equipped with paddle in hard pond fastly, flocculation basin mixes blender equipped with frame slowly, and equipment for separating liquid from solid is centrifuge.
A kind of oil gas field advanced waste treatment apparatus for no settling system that the utility model obtains, technical effect have with
Lower several points:
1, with sedimentation basin, the sludge concentration tank, more medium filter, activity in tubular ultra-filtration membrane system substitution original system
Carbon filter, cartridge filter reduce a large amount of techniques；
2, tubular ultra-filtration membrane integrated level is high, and equipment takes up little area, is easy to be made into skid-mounted type equipment, more meets at oil gas field sewage
The use condition of reason；
3, after reducing technique, operation is simpler, and technology stability is higher.
Detailed description of the invention
Fig. 1 is the advanced treatment system schematic diagram of oil gas field waste water under original technology
Fig. 2 is the advanced treatment system schematic diagram of the oil gas field waste water without settling system of embodiment 1
In figure: former pond 1, conditioning tank 2, electrocatalytic oxidation system 3, except hard pond 4, flocculation basin 5, tubular ultra-filtration membrane system 6,
Cache pool 7, RO system 8, equipment for separating liquid from solid 9, boring aeration device 10, paddle mix blender 11, frame fastly and mix blender slowly
12。
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples:
Embodiment 1:
As shown in Fig. 2, a kind of oil gas field advanced waste treatment system of no settling system provided by the utility model, in order to
