Pond connects.
The waste discharge pond is connected with breakdown of emulsion reaction tank, the waste water of wastewater disposal basin flow into again breakdown of emulsion reaction tank carry out breakdown of emulsion reaction and
Subsequent treatment, it is ensured that water outlet up to standard invariably, so as to reach environment protecting.
Effusion meter is set between the breakdown of emulsion reaction tank and Eddy concave air-floatation apparatus, can monitor in real time sewage load.
It is little according to the density of oil reservoir, up can float, the oil interceptor top sets oil drain out and waste discharge mouth, and oil drain out is higher than row
Useless mouth；Oil drain out is connected with sludge-tank by oil exit pipe, and waste discharge mouth is directly connected with wastewater collection pond.The oil of genuine oily waste water
Layer drains into sludge-tank by oil drain out and oil exit pipe；Waste water after oil removal flows into wastewater collection pond by waste discharge mouth.
Wastewater collection pond bottom sets waste discharge mouth, connects with breakdown of emulsion reaction tank.According to action of gravity, waste water is directly from waste discharge mouth
Breakdown of emulsion reaction tank is flowed into, and the oil reservoir of the waste water residual of bottom is few, realizes secondary oil removal.
It is an advantage of the current invention that：
1) using two grades of oil removals, acid stirring breakdown of emulsion, along with the mode of cavitation air flotation and air-dissolving air-float processes oily waste water
Water, its efficiency high, treatment effect are stable, reach after can making sewage disposal《Integrated wastewater discharge standard》(GB8978-1996)
Primary standard, i.e. petroleum-type≤10mg/L, SS≤70mg/L, colourity≤50, pH=6～9；
2) whole device adopts integrated compound mode, can effectively reduce space requirement, and occupation of land is little, and energy consumption is low, installs
Convenient transportation；
3) waste water in whole device enters back into breakdown of emulsion reaction tank by collection and carries out breakdown of emulsion and follow-up air supporting reaction, from
And ensure whole system no wastewater discharge, it is ensured that environment protecting.
4) standard configurations are adopted, is easy to keep in repair, manages.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings the present invention is illustrated further.
As shown in figure 1, after a kind of bearing cleaning oily waste water processing meanss, it is including oil interceptor 1, wastewater collection pond 2, broken
Newborn reaction tank 3, acid storage tank 4, storage alkali tank 5, PAC medicine-adding bins 6, PAM medicine-adding bins 7, Eddy concave air-floatation apparatus 8, dissolved air flotation device 9 with
And waste discharge pond 11, sludge-tank 10；
Breakdown of emulsion reaction tank 3, PAC medicine-adding bins 6, PAM medicine-adding bins 7, Eddy concave air-floatation apparatus 8, dissolved air flotation device 9 and waste discharge
Pond 11, sludge-tank 10 are respectively connected with running water pipe, are easy to dilute medicament and waste water, while can also clean when device is stopped using
Device.
Oil interceptor 1 connects genuine bearing cleaning oily waste water by elevator pump, and oil interceptor 1, wastewater collection pond 2 and breakdown of emulsion are anti-
Pond 3 is answered to be sequentially communicated；Agitator 12 is set in breakdown of emulsion reaction tank 3, and is connected with acid storage tank 4 by adding pump, by elevator pump with
