Description
Technical field
This utility model belongs to oilfield sewage treatment device, especially relates to the poly-high-sulfur oil-contained waste water treatment device of a kind of oil field height.
Background technology
The source of oilfield sewage is different, and composition is different, and concentration is different, its processing method is also different, especially sulfide, polymer ubiquity in oil field extracted water, bring serious corrosion and scaling, sulfate reducting bacteria SRB breeding, the series of complex problem such as difficult treatment.What the sewage disposal in current China oil field mainly adopted is following several method:
One, walnut shell filter method: oil-polluted water first passes through natural subsidence tank, coagulating setting tank technique desliming, removing oil, and the sewage after removing oil has filtered through walnut shell filter tank.Walnut shell filter is the separation equipment utilizing isolated by filtration principle to succeed in developing, and have employed oil resistant filter material special nucleus peach shell as filter medium, utilizes the characteristic that walnut shell specific surface area is big, absorption affinity is strong, holding filth capacity is big, removes the oil in water and float.This equipment has automatically and manually two kinds of control modes.During filtration, current from top to bottom, through water-locator, filter material layer, water collector, complete to filter.During backwash, agitator upset filtrate, current from bottom to top, make filtrate be thoroughly cleaned regeneration.
Two, By Bubble-floating Method: former water enters mixing reactor, mixing reactor adds medicament (degreaser or coagulant) to form separable flocculate, sewage after pretreatment enters air-floating apparatus, micro-bubble (the bubble diameter scope 30～50um) mixing of release in intake chamber sewage and air-water mixture.These micro-bubbles stick on the flco in sewage, form the proportion air float body less than water.Air float body rises to the water surface and is condensed into oil slick (or scum silica frost), is scraped to receiving oil (slag) groove by frizing (slag) machine；Precipitate at this at intake chamber heavier solid granule, discharged by sand flash valve.
Three, magnetic separation method: magnetic separation technique is first with flocculant, the float in sewage, sulfide and antibacterial etc. to be carried out tentatively good flocculation, it is simultaneously introduced adsorbent as wadding core (iron powder), add flocculation aid strengthen further and concentrate floc sedimentation, then through muddy water magnetic separator, walk is attracted on rotating disk, outside mud is rooted out water system simultaneously, remaining is exactly clear water, thus having reached the purpose of mud-water separation.
Four, centrifugal separation: the method is by adding a certain proportion of organic polymer coargulator or inorganic coagulant in sewage, implements the recovery of mud under the measure heated.In centrifugal separation processes, centrifugal rotational speed is more high, and centrifugation time is more long, and the moisture content of mud is more low；Temperature is more high, and cement homogenizes more good, and the separating effect of mud is more good.
The existence complicated operation of all respectively different degree of above-mentioned several method, processing cost are high, treatment effect is not good, secondary pollution, do not possess the defects such as commercial production conditions, especially the walnut shell filter method being widely used at present, the water inlet technological requirement of walnut shell filter is stricter, require that former water oil content should be less than 100mg/l, suspension content should be less than 50mg/l, so sewage to set up coagulation and the heavy technique of wadding before entering filter tank；The cleaning labor intensity of the replacing of filtrate simultaneously, sedimentation tank and settling tank is big, consumes substantial amounts of human cost, and backwashing sewage water enters in sedimentation tank, produces secondary pollution；The roping of the high-moisture-contensludge sludge after labor cleaning can produce high handling use, and the sewage after Treatment of Sludge is again fed to Sewage Disposal and processes, and causes the impurity vicious cycle in oil field ground process system containing partial vulcanization thing composition.
Summary of the invention
For defect and the deficiency of above-mentioned prior art, this utility model provides a kind of oil field height poly-high-sulfur oil-contained waste water treatment device.
The process device of the poly-high-sulfur oil-polluted water of oil field of the present utility model height, including settling tank, chemical-dosing mixer and filter, its spy is provided with sewage inlet at the top of settling tank, top is provided with receiving port, bottom is provided with sedimentation outlet of sewer, is provided with ultrasonic transducer on sewage inlet pipeline；Chemical-dosing mixer entrance connects outlet of sewer, sidewall connects drug feeding device, the bottom of outlet connection filter；Arrangement filtration core pipe in filter, filtration core pipe suitable for reading is also connected to pipeline, and pipeline connects filtered water tank, and the end opening of filter is sludge outlet.
As further improvement of the utility model, the sidewall of settling tank has pipeline to be connected to residual liquid case, residual liquid box top lead up to that cyclone is connected with the outlet of chemical-dosing mixer, another road pipeline at top is connected to filter bottom sidewall.
As further improvement of the utility model, the top of filter has compressed air inlet to be connected to and connecting leg road by heater, and another road pipeline of compressed air inlet is connected to the top of filter.
As further improvement of the utility model, filtration core pipe is that filter cloth is constituted by screen casing intussusception.
The process device of the poly-high-sulfur oil-polluted water of oil field of the present utility model height, adopts online hardening and tempering process, and automaticity is high, simple to operate；Equipment volume is little, sets up standby can completing and filters and dewatering work, it is not necessary to backwash, and electrical power consumed reduces by more than 80% compared to existing technology, and the low moisture dry mud of automatic-discharging reduces cost, non-secondary pollution；After utilizing the oilfield sewage that this utility model processes to separate, in mud, oil content is that < 0.3%, water content is that < 30%, in water, oil content is less than 8.5mg/l.In water, suspension content is less than 6.4mg/l, and water quality and mud after process are better than oil field standard.
