Abstract

The biological aerated filter-ozonizing-biological aerated filter processes were applied for advanced treatment of dyeing wastewater after secondary biochemical treatment. When the COD of the influent was between 90 mg/L and 150 mg/L, and the color was between 16 times and 32 times, the COD of effluent was reduced to less than 35 mg/L with the removal rate more than 75%, and the color is reduced to less than 4 times by these processes. The result of the engineering project showed that these processes performed stable and had high efficiency, with the effluent quality met the water quality requirement of washing process of textile for reuse.
