Description
Technical field
The present invention relates to a kind for the treatment of unit and method of oil extraction waste water, particularly relate to the device and method adopting and regulate pH breakdown of emulsion, gravity settling separation, centrifugation or dissolved air flotation, light electrolysis, anaerobism, the process combined treatment oil extraction waste water such as aerobic, belong to the field for the treatment of of water pollution of environmental engineering.
Background technology
Current, China's onshore oil field substantially all adopts waterflooding mode, namely injects high pressure water to stratum and drives crude oil to make it be extracted from oil well.After water filling after a while, injecting water will be plucked out of with crude oil, and along with the development time extends, extraction crude oil water content constantly rises.That exploit out with crude oil from stratum, containing crude oil oilfield produced water (also known as " recovered water "), the topmost class waste water being oil-field development and producing in producing.Due to the difference of the geologic condition, development scheme, oil formation improvement measure, injection water quality, gathering and transportation technology etc. in each oil field, the nature difference of each oil production waste water in oil field is very large.In general, oil extraction waste water has following characteristic:
(1) oleaginousness is high, the oil usually containing 1000 ~ 2000mg/L in oil extraction waste water, have even up to 5000mg/L, comprise oil slick, dispersed oil, oil in water emulsion and dissolving oil;
(2) containing suspended solids, particle diameter is generally 1 ~ 100 μm, mainly comprises: 1. silt particle; 2. various mineral substance; 3. bacterium: sulphate reducing bacteria (SRB) 5 ~ 10 μm, saprophytic microorganism (TGB) 10 ~ 30 μm; 4. organism: the heavy oils such as gum asphalt class and paraffin.
(3) saltiness is high, and the general inorganic salt content of oil production waste water in oil field is very high, and from several thousand to several ten thousand, hundreds of thousands of mg/litre even, each oil field, even each block, oil reservoir are all different; Mainly comprise: be 1. dissolved in the inorganic salts in water.Substantially exist with the form of anions and canons, its particle diameter is all 1 × 10
-3below μm, mainly comprise Ca

(4) containing bacterium, mainly saprophytic microorganism and sulphate reducing bacteria;
(5) high temperature and high pH, the water temperature of waste water mostly is 40 ~ 80 DEG C, and the pH of waste water is 6.5 ~ 9.5;
In addition, part oil extraction waste water is also containing tensio-active agent and polymkeric substance.
Current, the treatment technology of domestic oil extraction-generated waste water is mainly for produced-water reinjection design.The object of disposing polluted water in oil is the oil removed in water, suspended substance and other hinder water filling, easily cause the unfavorable composition of waterflood system burn into structure.Because the physical chemical differences of each oilfield produced water is comparatively large, therefore various Treatment Process for Oil Extraction Wastewater of Oil Field flow process is also not quite similar.Due to the difference of oil well reservoir characteristics, Produced Liquid physical property and oil field block distribution etc., environment protection improving constantly disposing polluted water in oil in addition, has the requirement of disposing polluted water in oil day by day to improve, disposing polluted water in oil and re-injection not a duck soup.
Along with the raising of environmental requirement, water resources day is becoming tight, and doing oilfield produced water process well is the task of top priority.Due to deepening continuously of oil production, water filling is a kind of conventional oil-field development technology, and many oil fields have entered middle and later periods mining phase, and crude oil water content even reaches more than 90%, and cause oil recovery treatment amount to increase very fast, intractability strengthens.Because water environment pollution is more and more serious, agenda has been laid out in oil extraction waste water process.In recent years, Oilfields oil extraction waste water Treatment process has improved and has improved.Change into oil removal → coagulation air-float → biochemistry → filtering technique by original oil removal → coagulation → filtering technique.Existing oil extraction waste water treatment technology mainly comprises: swash plate oil removing, oil removal by air bubbling, anaerobism (acidication), aerobic, precipitate and the step such as to disinfect.Chen Zhian etc. adopt anaerobism or acidication one aerobic activated sludge process process alkalescence oily(waste)water, and result of study thinks that biological (hydrolysis) acidifying one secondary aeration and sedimentation is the biochemical treatment flow process that oil refining alkaline water is suitable.Liu Huiqing etc. utilize flocculation-biological contact oxidation process process oily(waste)water, and result shows that COD clearance can reach 68%.Chinese patent CN104445792A describes oilfield sewage and first opens wide spray column through forced ventilation and carry out cooling, then by the process of A/O biochemical system, then add Ca (ClO)
2carry out oxide treatment, finally by the method for multi-medium filtering process being filled with gac, the inflow requirement COD of its sewage is 350 ~ 600mg/L, and water outlet is 50 ~ 150mg/L.Chinese patent CN1047100354A describes a kind of method for deeply treating water extracted out from oil field, comprises the steps: that oil field extracted water carries out cooling process again after pre-treatment, adds coagulated agent, and carry out Homogeneous phase mixing process; Pass into the method that immersion ultra-filtration equipment carries out ultrafiltration.
Deal with the work for instructing oil extraction waste water, Department of the Environment has put into effect " oil extraction waste water harnessing project technical specifications " (HJ2041-2014) in 2014, specification recommends adopts: the treatment process of oil extraction waste water → pre-treatment → anaerobic biological treatment → Aerobic biological process → biochemical aftertreatment → qualified discharge.In sum, although the treatment technology of oil extraction waste water is existing many, all there is following shortcoming:
1, containing a large amount of impurity in the oil reclaimed, the processing difficulties of the later use reclaiming oil is caused;
2, oil extraction waste water directly carries out air supporting after gravity settling, consume a large amount of flocculation agents and coagulant aids, causes working cost high;
3, can produce a large amount of oily sludges, the further process of mud can produce more expense;
4, the oil extraction waste water water-quality guideline after reclaiming oil can not meet the emission standard required in " oil extraction waste water harnessing project technical specifications " (HJ2041-2014) usually.
