1, make third elevator pump 36 in high liquid level by raw water by first liquid level gauge after the collection of collecting-tank 1 thick-oil waste water Be evacuated to hydrocyclone 2, water outlet flows into dosing air-dissolving air-float pond 3, when reaction by demulsifier stirring pool 27, PAC stirring pool 28, Demulsifier, PAC, PAM in PAM stirring pool 29 are slowly added in dosing air-dissolving air-float pond 3 according to dose, and water outlet flows into electricity wadding Oil removal and oil pollutant are further removed in solidifying flotation tank 4, to complete to enter the first pH adjusting in aforementioned preprocessing process Pond 5, while H is added2SO4H in pond 302SO4, to adjust sewage to acidity；
2, the sewage handled through step 1 inputs the first intermediate pool 6, when the liquid level in the first intermediate pool 6 reaches second When the scale liquid position of liquidometer, sewage is transported to by-pass filtration pond 8 by the first elevator pump 7, opens 37 (this of second solenoid valve When, the first solenoid valve 9 is closed) so that the sewage in by-pass filtration pond 8 flows into the second three-dimensional electrochemical pond 21, it is all kinds of to remove Persistent organic pollutants；
3, the sewage handled through step 2 inputs the 3rd pH conditioning tank 14, while third is added in the NaOH in the pond NaOH 31 PH conditioning tank 14, to input the second inclined-plate clarifying basin 15 after adjusting sewage to neutrality, to remove in the first three-dimensional electrochemical pond 13 The substances such as the mud and suspended matter of interior generation, subsequent sewage enter the second intermediate pool 16, the liquid level in the second intermediate pool 16 When reaching the scale liquid position of third liquid level gauge, sewage is transported to 18 (wherein filler of secondary filtration pond by the second elevator pump 17 Type and arrangement are identical as in by-pass filtration pond 8)；
4, the sewage handled through step 3 flows into A/O-MBR device 19, due to the place in aforementioned first three-dimensional electrochemical pond 13 Reason, so that through treated in the first three-dimensional electrochemical pond 13 sewage temperature between 35 DEG C~50 DEG C, furthermore, sewage is through A/O- After the processing of MBR device 19, sewage temperature can be maintained just between 20 DEG C~35 DEG C, and the temperature is bright for biochemical treatment advantage It is aobvious, biochemical system treatment efficiency can be increased substantially, avoid previous condensed oil sewage biochemical treatment temperature it is too low be difficult to handle it is up to standard The problem of；Finally, the sewage handled through A/O-MBR device 19 is pumped by discharge pond 34 by the second high-pressure pump 33, i.e., it is reachable To the primary standard qualified discharge in integrated wastewater discharge standard (GB8978-1996)；Meanwhile it can also will be in present treatment route Sludge is individually emitted into sludge-tank 35.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
