| 摘 要： | 讨论了在纺织印染污水处理中FeSO4絮凝污泥的回流脱色可行性.污泥回用的工艺为二级脱色,即首先用回流的污泥对印染污水进行脱色,污泥沉淀后排出系统.然后再用新鲜的FeSO4溶液进一步脱色,形成的污泥回流至第一脱色阶段.该工艺的优点是可以大幅度减少新鲜FeSO4的用量,继而减少污泥总量.

| Abstract: | The reflux decolorization feasibility on the FeSO 4 flocculation sludge in the treatment of textile printing & dyeing wastewater has been discussed.The process of sludge reuse is conducted in two-stage decolorization.It means that the printing & dyeing wastewater is firstly decolored with refluxed sludge,and,after the sludge is precipitated,is discharged from the system.Then the wastewater is further discolored with fresh FeSO 4 solution,and the formed sludge in second stage will be refluxed to the first st... |
