One, technical field
The present invention relates to the method for a kind of Hydrodynamic cavitation and ozone coupling treatment of sewage water.This method utilizes sewage through cavitation producer cavitation effect that produces and the streams of ozone coupling synergy of mixing, and makes the aerobic substance degraded in the sewage, to reach the purpose that reduces COD of sewage.
Two, background technology
Oil field extracted water is formed more complicated: it is not only polluted by crude oil, and it has also dissolved various salts and the gas in the stratum at high temperature, highly compressed oil reservoir; In oil recovery process, in oil reservoir, many suspended solidss have been carried; In oil recovery, oil-gas gathering and transportation, dehydrating of crude oil process, all kinds of chemical agents have also been added; Also have large amount of organic in the recovered water, the environment of suitable microorganism growth breeding is arranged.Therefore recovered water is the trade effluent that contains plurality of impurities.
Oxygen consumption pollutent in each that contains in the recovered water, the dissolved oxygen in the meeting consume water causes water oxygen content to reduce, water quality deterioration, hydrobiont is difficult to existence, is the important factor that influences water quality at present.Chemical oxygen demand (COD) is called for short COD, is an overall target of oxygen consumption pollution substance content in the expression water.COD content is too high, and the water quality corruption is seriously polluted.Therefore, sewage disposal requires the COD value not to be above standard.
The method that reduces COD has a lot, and commonly used is physics method, chemical method and biological process, and biological process is low than physics or chemical process cost, less investment, efficient height, non-secondary pollution, but the oil field waste biodegradability is relatively poor, and contains the organism of difficult degradation, has restricted the application of biochemical processing.
Three, summary of the invention
The method that the purpose of this invention is to provide a kind of Hydrodynamic cavitation and ozone coupling treatment of sewage water, solve difficult problems such as cost height, secondary pollution, biodegradability that above-mentioned sewage disposal faces are poor, difficult degradation, remedy the shortcoming and defect that prior art exists, the technology of a kind of low cost, high efficiency reduction COD of sewage is provided.
Technical scheme of the present invention realizes in the following manner:
The present invention is by by impeller pump, the cavitation effect that utilizes the Hydrodynamic cavitation generation that cavitation producer and ozonizer are formed and the strong oxidation of ozone and coupling sewage treatment are realized, the ozone that ozonizer is produced mixes in the sewage, together enter the cavitation producer, cavitation effect takes place in the cavitation producer, the microjet that produces by cavitation zone increases the contact area of ozone with sewage, the gas nuclear amount and the gas nuclear that prolong the action time of ozone in sewage and change in the sewage distribute, aerobic substance in the degradation of sewage, improve cavitation and ozone coupling effect, make COD reach the technical indicator of regulation.
Sewage treatment process of the present invention be sewage come water by pipeline through the impeller pump supercharging, by under meter metering again with produce by ozonizer and together enter the cavitation producer cavitation process that is coupled through the ozone of metering.Establish a vertical tank behind the cavitation producer, on jar pressure regulator valve is set, be used for the buffering of liquid and the release of gas, when the jar internal pressure is higher than setting pressure, open automatically, close automatically during less than setting pressure.The import and export of vertical tank are located at the middle and lower part and the middle and upper part of jar respectively.
In order to reach the COD index request, available multiple-stage treatment, and progression is adjustable.What this example adopted is the second-stage treatment flow process.
Compared with the prior art the present invention has the following advantages:
(1) Hydrodynamic cavitation and ozone coupling treatment of sewage water device simply, easily form skid system, energy consumption relative little, easy to operate, maintenance cost is low, easily realize mass-producing;
(2) Hydrodynamic cavitation and ozone coupling treatment of sewage water system utilize the Hydrodynamic cavitation effect, and liquid flow rate is big, and the device processes amount is big; Under the same treatment ability, its volume is less relatively;
(3) Hydrodynamic cavitation and ozone coupling treatment of sewage water system do not need to add any chemical agent, non-secondary pollution;
(4) Hydrodynamic cavitation and ozone coupling treatment of sewage water system are strong to the adaptation of sewage, can good Degradation all be arranged biochemical material poor, difficult degradation to some;
(5) Hydrodynamic cavitation and ozone coupling treatment of sewage water system handles cost are low, do not need the oversize residence time, the processing efficiency height.

Five, embodiment
The present invention is by by impeller pump 1 as shown in Figure 1, the cavitation effect that utilizes the Hydrodynamic cavitation generation that cavitation producer 4 and ozonizer 5 are formed and the strong oxidation of ozone and coupling sewage treatment are realized, the ozone that ozonizer 5 is produced mixes in the sewage, together enter cavitation producer 4, cavitation effect takes place in the cavitation producer, the microjet that produces by cavitation zone increases the contact area of ozone with sewage, the gas nuclear amount and the gas nuclear that prolong the action time of ozone in sewage and change in the sewage distribute, aerobic substance in the degradation of sewage, improve cavitation and ozone coupling effect, make COD reach the technical indicator of regulation.
Sewage enters from inlet pipe, through impeller pump 1, obtains certain pressure and flow velocity, and the ozone gas by ozonizer 5 generations with feeding from the aeration mouth together flows into the cavitation producer, in the cavitation producer cavitation effect takes place.The microjet that cavitation zone produces has played churned mechanically effect, increased the contact area of ozone with liquid, feed ozone to the cavitation pipeline simultaneously, not only prolonged the action time of ozone in solution, measure gentle nuclear distribution but also changed the gas nuclear in the liquid, help the nascent of cavitation, active effect has been played in the development of cavitation.Therefore, under the coupling of Hydrodynamic cavitation and ozone, the oxidation that is degraded of the aerobic substance in the sewage has reached the purpose that reduces COD.Sewage enters vertical tank 8 after flowing out from cavitation producer 4, and by air content in pressure regulator valve 6 controlling tank, sewage has so far been finished the one-level processing from vertical tank 8 outlet outputs.Sewage can together enter the cavitation producer with the ozone gas that feeds from the aeration hole once more and carry out second-stage treatment after flowing out from vertical tank 8.By sampling valve 7 sampling analysis, judge whether COD of sewage satisfies index request, and adjust processing progression with this.Note the pressure of tensimeter 2, remain the pressure that mixes ozone and necessarily be higher than pump discharge pressure, otherwise ozone just can not mix smoothly, mix up the mixed ratio of ozone and sewage, guarantee processing quality sewage by under meter 3.
