摘要：
Much work has been done on the dyeing water treatment by a new method of the combination of crossflow microfiltration, flocculation and ceramic membrane technique with some successful results caused by the advantages of the combination. The kind of flocculation and its dosage are studied, which is used to treat some wastewater. The best flocculation precepts are confirmed. And then, the effects on filtration rate are discussed. The CODcr and absorbency of sulfur black wastewater after treatment are up to national grade about drain wastewater. The CODcr and absorbency of 2,3-acidic wastewater and DSD acidic wastewater after treatment are also descend. Compared with organic membrane, ceramic membrane has exceptional performance of cleaning and regeneration. The results show that the dynamic filtration equipped with ceramic plate membrane as the filtration membrane has great advantages, and wide application future has been shown in membrane separation.
