The hydrophilic and hydrophobic particles are composed of hydrophilic particles and hydrophobic particles, and are filled in the annular bed layer according to a random proportion.

The annular bed layer and the filter screen are arranged coaxially.

And a liquid level meter is arranged on the peripheral surface of the oil storage tank.

By adopting the technical scheme, the method has the following advantages:

this application is equipped with hydrophilic and hydrophobic nature granule in the barrel is inside, adsorb and coalesce the greasy dirt through hydrophilic and hydrophobic shape granule, oleophilic hydrophobic fiber strip also has the coalescence to the greasy dirt simultaneously, tiny oil drips and gets into in the oil storage tank from advancing oil pipe or oil feed branch pipe after the growth, reach the back when the liquid level, concentrate and discharge, can get rid of a large amount of greasy dirt, set up hydrophilic oily membrane of dredging simultaneously, the greasy dirt that the band can not be through hydrophilic oily membrane of dredging in making the sewage after the annular bed, can only be discharged or wait for the absorption, the coalescence, this application deoiling ability promotes greatly.
