The oil-containing wastewater treatment device mainly comprises a reaction pool, a contact pool and an advection pool which are sequentially arranged and separated by partition plates, wherein the reaction pool is communicated with the lower part of the contact pool, the contact pool is communicated with the upper part of the advection pool, oil-containing wastewater enters the reaction pool via an ejector, ozone prepared by an ozone generator is introduced into the reaction pool, the upper part of the advection pool is connected with a waste oil recovery pipe, and the lower part of the advection pool is connected with a drainage pipe. The oil-containing wastewater treatment device disclosed by the utility model adopts the ozone generator as an aeration source, two processes of air flotation and ozone oxidation are integrated, most of oil type substances can be recovered, a small quantity of oil type substances can be oxidized, the oil-containing wastewater can be further treated, and a treatment process is simple.
Description
Technical field
The utility model relates to a kind of oil-containing waste water treating device.
Background technology
Oily(waste)water is one of common waste water in trade effluent, its common treatment process is coagulation+biochemistry+ultrafiltration+membrane bioreactor combination process, by filtering and biochemical process, make the oily substance in waste water change small molecules oil into, finally by biological degradation, the oil in waste water is removed, there are following shortcoming in traditional oily wastewater treatment method and device: 1, complex process, expense is high.Traditional technique is assembled technological and device at present, and its cost for wastewater treatment has become the bottleneck place of technique in real project using.2, the oils in waste water can not get reclaiming.Any pollutent likely becomes resource under some specific environment, the oil in waste water is no exception, can make fuel after recovery, or is further purified and separately is used as him, and traditional technology is mostly by addition degree of depth degraded of the oil in waste water at present.
Summary of the invention
The purpose of this utility model is to overcome the prior art defect, and a kind of oil-containing waste water treating device is provided.
The technical solution of the utility model is achieved in that a kind of oil-containing waste water treating device, mainly by arranging in turn and forming with reaction tank, contact tank, horizontal flow basin that dividing plate separates, reaction tank and contact tank bottom are communicated with, contact tank and horizontal flow basin top are communicated with, oily(waste)water enters reaction tank through ejector, ozone prepared by ozonizer passes into reaction tank, and horizontal flow basin top is connected with the waste oil recovery tube, and bottom is connected with water shoot.
Further, horizontal flow basin middle part has return line to be connected with reaction tank, can be back to reaction tank and carries out secondary treatment not obtaining the oily(waste)water of processing fully.
Further, contact tank and horizontal flow basin dividing plate top are provided with to the flow deflector of horizontal flow basin oblique upper.
The utility model adopts ozonizer as aeration source, air supporting and two kinds of techniques of ozone oxidation is integrated, and both recyclable most oily substance, can carry out oxidation by a small amount of small molecules oily substance again, make oily(waste)water obtain a step processing, and treatment process is simple.In addition, the utility model has adopted return line, can be back to system and carries out secondary treatment not obtaining the oily(waste)water of processing fully, thereby the oily sludge thing of processed waste water is reduced greatly.

Fig. 1 is the utility model structural representation.
In figure, the 1-ozonizer; The 2-ejector; The 3-reaction tank; The 4-contact tank; The 5-horizontal flow basin; 6-waste oil recovery tube;
The 7-return line; The 8-water shoot; The 9-flow deflector.
Embodiment
Below in conjunction with accompanying drawing, be further described:
As shown in Figure 1, a kind of oil-containing waste water treating device, mainly by the reaction tank 3 of arranging in turn and separating with dividing plate, contact tank 4, horizontal flow basin 5 forms, reaction tank 3 and contact tank 4 bottoms are communicated with, contact tank 4 and horizontal flow basin 5 tops are communicated with, oily(waste)water enters reaction tank 3 through ejector 2, the ozone of ozonizer 1 preparation passes into reaction tank 3, horizontal flow basin 5 tops are connected with waste oil recovery tube 6, bottom is connected with water shoot 8, middle part has return line 7 to be connected with reaction tank 3, can be back to reaction tank and carry out secondary treatment not obtaining the oily(waste)water of processing fully, contact tank 4 and horizontal flow basin 5 dividing plate tops are provided with to the flow deflector 9 of horizontal flow basin 5 oblique uppers, in order to waste oil, float.
This device, by dividing plate, is divided into reaction tank 3, contact tank 4 and horizontal flow basin 5 to main part, and following some benefit is arranged: 1) reaction tank 3 can be assembled oily(waste)water and ozone, increases the ozone concn in waste water, strengthens the oxidizing reaction effect.2) contact tank 4 and horizontal flow basin 5 are separated, the oxygen that can make to generate after the complete ozone of unreacted and reaction contacts with oily(waste)water fully, forms little rill, makes the oil floating in waste water, thereby reaches the purpose of oil removing.3) in horizontal flow basin 5, relatively long flow process can make to be with bubble oil droplet and waste water to be separated, and top is the bubbles oil droplet, reclaims by waste oil recovery tube 6, and bottom is the waste water after processing, and discharges by water shoot 8.
Working process is as follows:
1) start ozonizer 1;
2) oily(waste)water passes through ejector 2 jets to reaction tank 3;
3) ozone gas of ozone generator device 1 generation makes the oily sludge thing bubble in waste water on the one hand, by ozone oxidation, makes macromolecule contaminant be oxidized to the small molecules pollutent on the other hand, is easy to the later stage bubble;
4) oily(waste)water of the gas dissolved contact tank 4 of flowing through, in contact tank 4, oily(waste)water further contacts and bubble with gas;
5) oily(waste)water after abundant bubble flow to horizontal flow basin 5, and the waste oil after bubble is collected through waste oil recovery tube 6; Waste water after processing is discharged by water shoot 8;
6) the horizontal flow basin 5 middle portions waste water that still contains a small amount of greasy dirt is back to reaction tank 3 through return line 7 and processes.
