Abstract:

With the development of ultrafiltration membrane off-line cleaning technology and the requirements of running cost reduction of vacuum ultrafiltration membrane，the traditional mode of periodic replacement of ultrafiltration membrane in enterprises has gradually converted to off-line cleaning resuscitation. The pollutant species， content，pollutant distribution conditions in ultrafiltration membrane for sewage recycling is analyzed and evaluated comprehensively. Scheme of cleaning without membrane damage has been designed and applied，acquiring obvious cleaning effect.

Key words: oil-bearing wastewater, ultrafiltration membrane, off-line cleaning
