Abstract
An oil-water mixture treatment device has a laminar separator and an electric field separator. The laminar separator has a coalescing tube with coalescing filler provided therein, a separating tube arranged above the coalescing tube, and a discharging tube arranged above the separating tube. The coalescing tube is connected to said separating tube by a first connecting tube group and the separating tube is connected to the discharging tube by a second connecting tube group. The oil-water mixture to be treated enters, after being treated in the coalescing tube, the separating tube through the first connecting tube group for laminar separation. The resulting oil phase enters the discharging tube through the second connecting tube group and then is discharged through an oil discharge pipeline, while the resulting water phase enters the electric field separator from a lower portion of the separating tube for a next stage of separation.
