(12) the molten gas of third time is carried out in the inlet line of bulk processing tank water outlet to thin process tank；
(13) water after molten gas enters in the turbulent air bearing component of thin process tank internal upper part, carries out the 4th air bearing；Turbulent air bearing
In micro-vortex the small oil droplet in sewage is agglomerated into big oil droplet, little particle is agglomerated into bulky grain；
(14) water after turbulent air bearing, which enters in fine filtering layer, is carefully filtered；Filtered water is discharged into essence from tank bottom water outlet
Filtering tank；
(15) thin filtered water enters smart filtering tank progress metal membrane filtration essence filtering；
(16) the filtered water of essence carries out electricity into antiscale inhibition tank and disappears the processing of cationic polar in smart filtering tank, treated water
It is spare into treated water tank.
3. the method for sludge treatment that a kind of oil field ternary drove and infused poly- sewage physical treatment, characterized in that include the following steps:
(1) the collected soiling solution of pollution discharge pond is squeezed into greasy filth water separation tank by mud lift pump promotion；
(2) it is stirred in greasy filth water separation tank, adding medicine, coagulation, sedimentation；
(3) oil is recycled to drains receptacle after settling, and water, which returns, promotes pump inlet, and mud squeezes into sludge condensation curing by pressure slurry pump
In；
(4) it is concentrated and solidifies through sludge condensation curing, effluent recycling to pollution discharge pond, sludge pack outward transport reprocessing, to complete
Treatment of Sludge.
