Specific embodiment
Technical solution of the present invention is further elaborated combined with specific embodiments below.
It is commercial product that the present invention, which is recycled component all in agent prescription,.
The treatment process of present invention rolling Zero discharge:
It after emulsion is discarded, is first collected into wastewater disposal basin, when processing is driven into level-one knockout drum, by oil in emulsion
0.5%~2% ratio of amount adds oil-water separating agent, is then turned on stirring, stir 20~after forty minutes, waste emulsified mixture is squeezed into
In the second-order separation tank, stand 60~120 minutes, at this point, oil-water separating agent by the droplet size in emulsion increase to 50um with
On.Under static condition, the oil droplet in emulsion can float, and different from traditional flocculant, the oil-water separating agent of addition can be incited somebody to action
The olesome of floating is assembled, and finally forms transparent hardly aqueous oil reservoir in liquid surface, rather than cotton-shaped suspension
Object, and bottom aqueous layer is also clear, and in the second-order separation tank, the water phase bottom of separator well is drained into tank, can be with
It is used as milling train moisturizing；Oil reservoir overflow after running up to certain amount in the second-order separation tank, into recycling oil tank, recycling
Oil tank bottom is equipped with discharging valve, to discharge a small amount of moisture brought into oil recovery because time of repose is too short.
Oil recovery after separation can obtain miscella, miscella can be used as normal rolling with rolling crude oil mix and convert in proportion
