Filtration Characteristic of Modified Polytetrafluoroethylene Membranes in Disposing Oily Sewage

摘要

This article mainly expounds the study and the related analysis of filtration experiment operated by the oily sewage filtration installation which is independently developed, and processed by modified polytetrafluoroethylene membranes. The experimental result indicated that oil content of the oily sewage sample was<2mg/L after processed by 0.45, 0.8 and 1.0μm modified PTFE membranes, and the oil-eliminated rate could be up to 90%, and could satisfy emission and the request under the standard GB8978-1996.
