Description
Technical field
This utility model belongs to technical field of waste water processing, is specifically related to a kind of oil field wastewater treatment system.
Background technology
Along with the quickening of oil field development process, oil field waste is increasing, seriously pollutes ecological environment.Oil field waste water quality is complicated, containing contaminated environment materials such as petroleum demulsifier, salt, phenol, sulfur.Oil field waste mainly includes crude oil and deviates from other type of oily waste water in water (having another name called oil field extracted water), well-drilling waste water and station.The process of oil field waste can have various ways according to factors such as oil field production, environment.When oil field needs water filling, oil field waste is reinjection into reservoir after treatment, now the float in water, wet goods many index strictly to be controlled, it is prevented that stratum is produced injury by it.Petroleum Production unit is largely focused on arid area, water resource famine, how to be turned waste into wealth by the waste water produced in oil recovery process, is of great practical significance.
Current oil field wastewater treatment technique, main employing " delivering medicament air supporting waste water filtering " or " delivering medicament precipitation waste water filtering ", two grades settle the mode combined with cascade filtration and act on oil extraction waste water process program.The problems such as this method processes not thorough, and depolymerization is inconspicuous, and the water quality after process is difficult to meet reinjected water index request, and meanwhile, existing method treating capacity is little, processes costly, and equipment conveying is inconvenient govern again the process of oil field waste.Therefore, along with deepening continuously of oil field wastewater treatment research, the oil field wastewater treatment system efficient, convenient, cost performance is high becomes study hotspot.
Utility model content
In order to overcome, existing oil field wastewater treatment is thorough, treating capacity is little and processes costly, and the deficiency of equipment conveying inconvenience, this utility model provides a kind of oil field wastewater treatment system.
This utility model solves its technical problem and be the technical scheme is that
A kind of oil field wastewater treatment system, including grille well, pretreatment pool, thick oil interceptor, regulates oil separation tank, buffer tank, one-level flotation tank, secondary air-floatation pond, catalytic oxidation pond, A/O biological contact chamber, biochemical sedimentation basin and detection cell；Described grille well one side ducts connects pretreatment pool, described pretreatment pool one side ducts connects thick oil interceptor, described thick oil interceptor one side ducts connects adjustment oil separation tank, described adjustment oil separation tank one side ducts Connection Cache tank, described buffer tank one side ducts connects one-level flotation tank, described one-level flotation tank one side ducts connects secondary air-floatation pond, described secondary air-floatation pond one side ducts connects catalytic oxidation pond, described catalytic oxidation pond one side ducts connects A/O biological contact chamber, described A/O biological contact chamber one side ducts connects biochemical sedimentation basin, described biochemical sedimentation basin one side ducts connects detection cell；It is divided into three regions by dividing plate inside described adjustment oil separation tank, dividing plate is provided with inclined plate sedimentation device；Described A/O biological contact chamber is internally provided with anaerobic pond and Aerobic Pond, and Aerobic Pond connects aerator and ozonator by aerating pipelines.Grille well Main Function is to prevent line clogging, and grid passage also reduces certain pollutant burden while cutting dirt.Waste water, through pretreatment pool, is removed upper strata oil slick, and it is carried out pretreatment, makes waste water destroy replacing and float stabilising system of waste water when acid, alkali, reaches the pretreatment purpose of preliminary sedimentation.Regulate the inclined plate sedimentation device within oil separation tank and the swash plate that polylith is parallel is set, oil waste water enters from inclined plate sedimentation device bottom, flow out from inclined plate sedimentation device upper end, make use of lamina flow principle, reach following purpose: (1) improves the ability of the solid particle processed in oil waste water of oil interceptor, and shorten the distance of particles settling, shorten the sedimentation time；(2) control the flow velocity of current, add the settling area of oil interceptor, improve treatment effeciency；(3) oil waste water can drive greasy dirt therein to flow up when flowing up, and utilizes the principle that oil ratio water is light, is isolated on the water surface of oil interceptor by greasy dirt；Therefore this utility model improves oil removal effect by changing the flow direction of waste water, improves the separation rate of greasy dirt, makes oily waste degradation rate can reach more than 90%.Buffer tank storage waste water, it is prevented that flow is excessive causes that aftertreatment systems load increases, oil field wastewater treatment deleterious.One-level flotation tank and secondary air-floatation pond form the micro-bubble of high degree of dispersion in water, adhere to solid or the liquid particles of hydrophobic group in waste water, form water-gas-granule three-phase mixed system, after particle adhesion bubble, form apparent density and float to the water surface less than the flco of water, formation scum layer is stripped off, thus by solid-liquid or Liquid liquid Separation.Oil field waste is sterilized and filters by catalytic oxidation pond.Utilize the effect of anaerobe in anaerobic pond, make Organic substance be hydrolyzed, acidifying and methanation, remove the Organic substance in waste water, and improve the biodegradability of waste water, be conducive to follow-up Aerobic Process for Treatment；Aerator passes through aerating pipelines to Aerobic Pond air inlet aeration so that ozone and waste water are fully contacted, and allow activated sludge carry out aerobic respiration, further Organic substance is resolved into inorganic matter, removes the function of pollutant.Activated sludge and waste water are easily separated by biochemical sedimentation basin, and detection cell can be monitored in real time in convection current water outlet according to actual needs, convenient monitoring.
Preferably, described grille well is internally provided with thickness twice grid, improves clean effect further.
Preferably, described thick oil interceptor and adjustment oil separation tank upper end connect elevator pump by pipeline, and the convenient waste oil that will swim in waste water upper end is extracted out.
Preferably, described pipeline many places are provided with effusion meter and valve, facilitate monitor in real time and control the flow of whole system waste water.
Advantage of the present utility model:
(1) the independent skid of each equipment of this utility model, convenient transport, operating cost is relatively low；
(2) this utility model dosing is less, and reagent cost is low, environmental protection；
(3) this utility model operation wastewater time in systems is shorter, and waste water treatment efficiency is higher；
(4) waste water after this utility model process can meet re-injection requirement, meets the oil field wastewater treatment market demand.
