A. air-flotation process：After each plant effluent is collected, it is pumped up to flotation tank, while air is passed through into flotation tank, to useless
Water carries out air-flotation process and removes suspension in water removal, and waste water residence time in flotation tank is 2h；
B. regulation is handled：Flotation tank water outlet is promoted to regulating reservoir with pump, and waste water pre-acidified, regulating reservoir is interior to carry out boring aeration, will
Waste water stirs homogeneous, and waste water residence time in regulating reservoir is 36h, and regulating reservoir discharges water to iron-carbon micro-electrolysis pond；
C. microelectrolysis processing：It is 3 ~ 4 that a small amount of spent acid regulation pH value is added into iron-carbon micro-electrolysis pond, carries out iron-carbon micro-electrolysis, together
When iron-carbon micro-electrolysis bottom of pond portion carry out boring aeration, waste water is 2.5h in the iron-carbon micro-electrolysis pond residence time, and water outlet afterwards is going out
Regulation pH value adds aluminium polychloride, PAMA, completed by the hydraulic mixing of outlet canal to after 8 ~ 9 in water channel
Preliminary sedimentation tank is flowed into after coagulation process；
D. precipitation process：Waste water precipitates 4 ~ 5h in preliminary sedimentation tank, and supernatant water outlet is promoted in anaerobic pond by pump,；
（2）Biochemical treatment：
A. Anaerobic Treatment：Waste water carries out anaerobic reaction in anaerobic pond, is provided with more diving mixers in anaerobic pond, waste water is stirred
Mix uniformly, promote waste water hydrolysis acidification in anaerobic pond, retention time of sewage 30h；
B. anoxic treatment：Anaerobic pond overflow is discharged water in anoxic pond, waste water denitrogenation dephosphorizing in anoxic pond, by organic of macromolecular
Grain resolves into small molecule organic granular, retention time of sewage 4h；
C. Aerobic Process for Treatment：Anoxic pond is discharged water in Aerobic Pond, carries out aeration Aerobic Process for Treatment, and Flat Membrane is disposed with Aerobic Pond, real
Existing HRT separates with SRT, retention time of sewage 19h, while in Aerobic Pond in backflow mixed liquor to anoxic pond, carries out denitrification
Effect, denitrogenation processing is carried out to waste water；
（3）Advanced treating：
Precipitated in Aerobic Pond water outlet overflow to intermediate pool, standard water discharge is discharged after precipitation, through pump if water outlet is below standard
It is promoted in active carbon filter, standard water discharge is discharged after charcoal absorption is filtered；Precipitating sludge in intermediate pool passes through
Sludge reflux pump lifting is back to supplement suspended sludge in anaerobic pond, promotes microorganism in anaerobic pond to carry out anaerobic respiration；
（4）Treatment of Sludge
Flotation tank, preliminary sedimentation tank and sludge caused by Aerobic Pond flow into sludge-tank, then through being carried out in sludge pumping to plate compression pond
After filter-press dehydration, caused dry mud cake outward transport.
2. the microelectrolysis processing technique of a kind of dyeing waste water according to claim 1, it is characterised in that in the regulating reservoir
It is disposed with boring aeration pipe.
A kind of 3. microelectrolysis processing technique of dyeing waste water according to claim 1, it is characterised in that the micro- electricity of iron carbon
Xie Chi bottom of pond is disposed with boring aeration pipe, and upper strata sets supporting layer, according to iron carbon mass ratio 2:1 laying forms 2m thickness fillers
Bed.
4. the microelectrolysis processing technique of a kind of dyeing waste water according to claim 1, it is characterised in that in the Aerobic Pond
Provided with boring aeration pipe and air blower.
A kind of 5. microelectrolysis processing technique of dyeing waste water according to claim 1, it is characterised in that the activated carbon mistake
The filtering velocity of filter is 5 ~ 8m/h.
