The biological aerated filter-ozone oxidation-biological aerated filter combined process has been appliedto the advanced treatment of dyeing wastewater after secondary biochemical treatment.When the COD of the irdluentis 90-150 mg/L,chroma 16-32 times,the COD of effluent is reduced to less than 35 mg/L after treated by this pro-cess,the removal rate is more than 75%,and the chroma is reduced to less than 4 times.The result of the engineeringproject SHOWS that the advanced treatment system runs stably,and has high treatment efficiency,and the water qualityof the effluent meets the recycling requirements of the washing water process at the textile printing plant.
