臭氧-BAF工艺在印染废水深度处理工程实例

Ozone-BAF process in the printing and dyeing wastewater treatment project example

采用"混凝沉淀+臭氧催化氧化+曝气生物滤池(BAF)"组合工艺,对印染废水二级生化处理出水进行提标改造深度处理,设计运行条件下,臭氧投加量为30~40mg/L,处理出水达GB18918-2002《城镇污水污染物排放标准》一级B标准。

The combination of“coagulation sedimentation ＋ ozone-catalyzed oxidation ＋ biological aerated flter （BAF） ” was used to carry out the secondary treatment of the secondary biochemical treatment effuent of the dyeing wastewater. Under the design and operation conditions, the dosage of ozone is 30~40mg/L, treatment of water to GB18918-2002 《urban sewage pollutant discharge standards》a B standard.
