Abstract :
In this work, the advanced treatment of the biologically treated wastewater of a textile plant using combination of ozonation and two-stage biological aerated filter (BAF) was studied. Comparing different ozone dosing methods, it was found that the integrated device including ozonation and BAF, allowed a higher COD (chemical oxygen demand) and color reduction. Comparing different treatment processes, it was found the combination of the integrated device and up-flow biological aerated filter allowed a higher pollutant reduction. After the ozonation and two-stage biological treatment, an effluent was obtained with the average COD of 26.7 mg/L, turbidity of 4.2 NTU, SS(suspended solid) of 2.0 mg/L, ammonia nitrogen of 0.6 mg/L and color of 2 degree.
