Description

technical field

[0001] The invention relates to a cleaning agent for ceramic membranes, belonging to the technical field of cleaning agents. Background technique

[0002] Two types of ceramic membrane separation equipment are required for the treatment plant of oily wastewater from steel cold rolling. One is an ultrafiltration oil removal device, which uses ultrafiltration ceramic membranes as filter materials, and mainly separates large molecular oils and small molecular waters in wastewater; the other is membrane bioreactors, which use microfiltration ceramic membranes as filtration materials. The material mainly separates the large particulate matter (suspended solids, microorganisms) in the wastewater decomposed by microorganisms and the clean water of small particles. After running for a period of time, the ceramic membranes in these two types of ceramic membrane separation equipment will be polluted and blocked by macromolecular oils and large particles in the wastewa...
