Background technique
Currently, foam production gas technology is commonly employed in terms of oil gas field water pumping gas production, foam production gas technology be by
Foam discharging agent injection air water after contacting shaft bottom liquid with foam discharging agent, by the agitation of natural gas flow, generates a large amount of low with adopting in well
Density, aqueous foam, foam take water with air-flow from shaft bottom to ground, reach stable, increase production and extend the purpose of its flush stage.Bubble
Row's agent can reduce stratum water surface tension, reduce density, reduce resistance caused by vortex, and bottom-hole cleaning.Want processing
The water that gas production generates, is a pretty troublesome thing.
Summary of the invention

Science and engineering skill improves the effect of processing well, reduces the cost of processing, while preferably improving the scope of application.
The technical scheme adopted by the invention is that: a kind of gas production waste water treatment process, comprising the following steps:
Step 1: pass through the descending three layer filtration net in aperture, the silt and large granular impurity in filtered wastewater；
Step 2: precipitating in sedimentation basin, oxidant is added in precipitation process, precipitates 15h-20h；
Step 3: extracting the water on sedimentation basin upper layer, it is added into waste water by hydrogen peroxide and FeSO4 by 1:2's or 1:2.5
The mixed mixed liquor of ratio is aoxidized, oxidization time 6h-8h；
Step 4: PAC and PAM is added in waste water, coagulation is carried out, coagulation time 3h-4h mixes the suspended matter in waste water
Congeal into particle；
Step 5: getting rid of surfactant, the small-molecule substance in waste water using foam fraction factor or pneumatically supported method
And the gas of irritant smell；
Step 6: heating, heating temperature is 120 DEG C -150 DEG C, and heating time 3h-5h is vaporized；
Step 7: condensation, is discharged after the vapour after gasification is condensed into water.
In one embodiment, in step 2, oxidant is added in precipitation process, precipitates 20h.
In one embodiment, it in step 3, is added into waste water and is mixed by hydrogen peroxide and FeSO4 in the ratio of 1:2
Mixed liquor after conjunction carries out oxidation 8h.
In one embodiment, in step 4, PAC and PAM is added in waste water, carries out coagulation, coagulation time 4h.
In one embodiment, in step 4, PAC and PAM ratio is 1:1.
In one embodiment, in step 6, heating temperature is 150 DEG C, heating time 5h.
The beneficial effects of the present invention are: the bright influence for reducing external factor to entire treatment process of this technique, it can
A variety of different waste water are adapted to, improve the scope of application, method overall simple, the treatment effect of each step is it is obvious that gather around
There is good using effect, while cost is relatively low for investment needed for the present invention, economic value is high, can preferably promote industry
Development, while environment is preferably protected, reduce the influence that enterprise produces discharge environment to periphery.
Specific embodiment
Below in conjunction with specific embodiment, invention is further described in detail.
