The invention relates to a treatment method and a
treatment system for zero-emission purification of high-
viscosity polymer-containing oil
silt. The treatment method comprises the following implementation steps that: heating and overflowing are conducted in a pretreatment tank; water and chemicals are added into primary and secondary
impurity removal machines to remove impurities; heating, homogenizing and overflowing are conducted in a heating homogenizing tank; a
slurry pump is connected in series with a first-stage
cavitation oil removal separation tank, a second-stage
cavitation oil removal separation tank and a third-stage
cavitation oil removal separation tank to treat the oil
silt; a material from an upper outlet of a fine sand
cyclone separator supplies liquid to centrifuges through a centrifugal
machine liquid supply
buffer tank, and a lower outlet discharges clean sand through a clean sand
dehydration device; a primary fine mud treatment tank is used for receiving and treating
oil water overflowing around; the
effluent of the first-stage
centrifuge and the
effluent of the second-stage
centrifuge enter a second-stage fine mud treatment tank to be treated; secondary centrifugal treatment is conducted on the fine mud through a mud stirring tank, and then clean mud is discharged; an
aeration system and an oil scraping
machine are mounted in an oil-water separation tank; awater pump is connected with a
sewage treatment tank to form closed circulation through a
heating furnace, and oil is output; and a
building material cured product is prepared from clean
silt. According to the invention, zero-emission purification treatment is completely achieved, and the problem of secondary
pollution caused by purification treatment of the high-
viscosity polymer-containing oilsilt is solved.
