Description
Technical field
The utility model relates to biochemical sewage process field, is specifically related to a kind of sewage disposal device.
Background technology
Main containing pollutents such as acetic acid, acetic acid and toluene in chemical engineering sewage, the treatment technology of these organic pollutants generally comprises physics, chemistry and biological method; According to the height of Pollutant levels, the selection of its monotechnics is distinct.To high-enriched organics, because it exists the concentration threshold values of biological inhibition, usually adopt the method for physical/chemical, as evaporation/extraction/absorption/membrane sepn/oxidation etc., above method is stable, but control condition requires higher, and running cost costly.To low-concentration organic, usually the method for biological treatment is adopted both at home and abroad, be characterized in that operation is comparatively stable, operational condition requires relatively low, and if do not needed high temp/high pressure etc., most distinguishing feature is that running cost is lower, often ton cost of water treatment is between several unit to tens of unit, but be not also perfect, its defect is that occupation of land is relatively large, and initial investment is relatively high.Traditional processing mode adopts the mode that combines with anaerobic digestion of coagulating sedimentation, usually can't meet COD and be less than the requirement that 500mg/l and toluene is less than 0.5mg/l in the sewage after such mode process.
Summary of the invention
The purpose of this utility model is to provide a kind of sewage disposal completely, entirely to pile sufficient COD to be less than a kind of sewage disposal device that 500mg/l and toluene is less than the requirement of 0.5mg/l.
The technical scheme that the utility model is taked is:
A kind of sewage disposal device, comprise the preoxygenation pond be connected in series successively, coagulating sedimentation device, equalizing tank, UASB anaerobic pond, settling tank and coagulative precipitation tank, described settling tank is provided with the pipeline being back to UASB anaerobic pond, denitrification device is serially connected with between described settling tank and coagulative precipitation tank, described denitrification device comprises the hypoxia response pond be connected in series successively, high-speed jet pond and Aerobic Pond, described Aerobic Pond is provided with the pipeline being back to hypoxia response pond, the output terminal of described settling tank connects the input terminus in hypoxia response pond, the output terminal of described Aerobic Pond connects the input terminus of coagulative precipitation tank.
Further, comprise the following steps: waste water passes in preoxygenation pond by a., in preoxygenation pond, after reaction, overflow, to coagulating sedimentation device, adds PAC flocculation sediment in coagulating sedimentation device, and the waste water on coagulating sedimentation device top is pumped to equalizing tank and is adjusted to neutrality; B. be adjusted to neutral waste water to pump to UASB anaerobic pond and carry out the biological degradation of pressure oxygen; Sewage after degraded pumps into precipitation in settling tank, and the sludge settling thing bottom settling tank is back to the degraded of UASB anaerobic pond secondary; C. the sewage in settling tank pumps in hypoxia response pond, SODIUMNITRATE is added in hypoxia response pond, complete denitrification reaction entering successively in high-speed jet pond and Aerobic Pond, the foul water fraction in Aerobic Pond is back in hypoxia response pond and carries out secondary or repeatedly denitrification reaction; D. the sewage after denitrification reaction pumps in coagulative precipitation tank and precipitates, and after having precipitated, the sewage at top is discharged, and the mud of bottom is sent to dry press filtration.
After taking above technical scheme, the beneficial effects of the utility model are: waste water enters preoxygenation pond, under the effect of preoxygenation, carry out the conversion of material, be separated by the mode of coagulating sedimentation, after pre-treatment, waste water carries out the homogenizing that equalizing tank carries out the water yield, water quality again.Homogeneous comprehensive wastewater pumps into UASB anaerobic reactor and carries out anaerobic biodegradation, and remaining macromolecular substance and toluene class material, under the effect of the sour flora of hydrolysis, Partial digestion, are partially converted into structure simpler organic acid, alcohol relatively.Being less than to meet water outlet COD the emission request that 500mg/L and toluene is less than 0.5mg/L, water outlet being reacted to UASB and adopts A-O(high loading further)-O(underload) denitrification process carries out depth degradation.Biochemical two settle out after water arranges coagulating sedimentation device, and as the means of checking on, guarantee standard water discharge, water outlet enters discharge pond, qualified discharge, and coagulating sedimentation, biochemical section get rid of excess sludge, enter sludge thickener, and after utilizing plate-and-frame filter press press filtration, mud cake outward transport is disposed.Equipment is simple, and treatment effect is good.
