摘　　要：蜡染印花含蜡废水蜡质含量高,应预处理进行蜡回收。对蜡染印花生产废水清浊分流,分流后的机械洗蜡废水采用双级气浮处理,蜡回收率和废水回用率可达90%以上;皂化脱蜡废水经酸化气浮处理,蜡回收率可达92%以上,回收蜡质可重复利用。蜡回收后处理水再与其它废水混合进行综合处理,出水易于达标排放。It is very important to recover the wax from the wastewater from wax printing production. The technology of the treatment of the splitting wastewater from wax printing production has been studied and applied to the practical engineering. The results show that when the split flow containing wax under mechanical action is treated by the double air flotation, the reuse rate of the wastewater and the recovery of the wax in the wastewater are all over 90%, when the split flow containing wax under saponification is treated by acidification and the air flotation, the recovery of the wax in the wastewater is over 92%, and the wax recovered from the wastewater can be reused. The mixing wastewater is treated by the comprehensive technology, the effluent quality can meet The National Sewage Discharge Standards.
