Device and method for treating organic-material-containing water

摘要

The present invention breaks down and removes various organic materials contained in oil-field water all at once. To this end, this method for treating oil-field water is provided with: a step for obtaining primary treated water containing organic material by removing the solid content and oil content from oil-field water; and a breakdown step for breaking down the organic material by exposing the primary treated water to discharge plasma, wherein the discharge plasma is generated by a nanosecond pulsed power supply for outputting a pulse having a pulse width of 10ns or less.
