Background technology
The pollutant such as acetic acid, acetic acid and toluene, the treatment technology one of these organic pollutions is mainly contained in chemical engineering sewage
As include physics, chemical and biological method；According to the height of pollutant levels, the selection of its monotechnics is distinct.Right
High-enriched organics, because it has the concentration threshold values of biological inhibition, generally using the method for physical/chemical, such as evaporation/extraction
Take/adsorb/membrance separation/oxidation etc., above method is stable, but control condition requirement is higher, and operating cost is costly.Right
Low-concentration organic, both at home and abroad generally using the method for biological treatment, is characterized in running relatively stable, operating condition requirement phase
To relatively low, such as it is not required to high temp/high pressure etc., distinguishing feature is that operating cost is relatively low, often ton cost of water treatment is in several units extremely number
Between ten yuan, but also it is not perfect, its defect is that occupation of land is relatively large, and initial investment is of a relatively high.Traditional processing mode
By the way of coagulating sedimentation is combined with anaerobic digestion, such mode process after sewage in be generally not met by
Cod is less than 500mg/l and toluene is less than the requirement of 0.5mg/l.
Content of the invention
It is an object of the invention to provide a kind of sewage disposal is piled completely, entirely, and sufficient cod is less than 500mg/l and toluene is little
A kind of sewage disposal device and technique in the requirement of 0.5mg/l.
The technical scheme that the present invention takes is:
A kind of sewage disposal device, including the preoxygenation pond being sequentially connected in series, coagulating sedimentation device, regulating reservoir, uasb anaerobic pond,
Sedimentation tank and coagulative precipitation tank, described sedimentation tank is provided with the pipeline being back to uasb anaerobic pond, described sedimentation tank and coagulating sedimentation
It is serially connected with denitrification device, hypoxia response pond that described denitrification device includes being sequentially connected in series, high-speed jet pond and aerobic between pond
Pond, described Aerobic Pond is provided with the pipeline being back to hypoxia response pond, and the outfan of described sedimentation tank connects the defeated of hypoxia response pond
Enter end, the outfan of described Aerobic Pond connects the input of coagulative precipitation tank.
Further, comprise the following steps: waste water is passed through in preoxygenation pond a., in preoxygenation pond react after overflow extremely
Coagulating sedimentation device, adds pac flocculation sediment in coagulating sedimentation device, and the waste water on coagulating sedimentation device top is pumped and adjusted to regulating reservoir
To neutrality；B. adjust to pump to neutral waste water and carry out pressing oxygen biodegradation to uasb anaerobic pond；It is heavy that sewage after degraded pumps into
Precipitate in the pond of shallow lake, the sludge settling thing of sedimentation tank bottom is back to the secondary degraded of uasb anaerobic pond；C. the sewage pump in sedimentation tank
Enter in hypoxia response pond, in hypoxia response pond, interior interpolation sodium nitrate, completes to take off in sequentially entering high-speed jet pond and Aerobic Pond
Nitrogen reacts, and the foul water fraction in Aerobic Pond is back in hypoxia response pond and carries out secondary or multiple denitrification reaction；D. denitrification reaction
Sewage afterwards pumps in coagulative precipitation tank and is precipitated, and after the completion of precipitation, the sewage at top is discharged, and the mud of bottom is sent to drying
Filter pressing.
After taking above technical scheme, the invention has the benefit that waste water enters preoxygenation pond, in the effect of preoxygenation
Under, carry out the conversion of material, then carry out separating by way of coagulating sedimentation, after pretreatment, waste water is adjusted pond and carries out water
Amount, the homogenizing of water quality.Homogenizing comprehensive wastewater pumps into uasb anaerobic reactor and carries out anaerobic biodegradation, remaining macromolecular substances with
And first benezene material is in the presence of the sour flora of hydrolysis, Partial digestion, be partially converted into the relatively simpler organic acid of structure,
Alcohol.In order to meet, water outlet cod is less than 500mg/l and toluene is less than the emission request of 0.5mg/l, and uasb reaction water outlet is entered
One step adopts a-o(high load capacity)-o(underload) denitrification process carries out depth degradation.The biochemical two setting coagulations after water that settle out sink
Shallow lake device, as the means of checking on it is ensured that standard water discharge, water outlet enters discharges pond, qualified discharge, and coagulating sedimentation, biochemical section exclusion are surplus
Remaining mud, enters sludge concentration tank, and after filter press filter pressing, mud cake outward transport is disposed.Equipment is simple, high treating effect.
