This work focused on the advanced treatment of the biologically treated wastewater of a textile plant. Nowadays, treatment methods for water reuse are mainly membrane technologies. According to the difficulty of concentrate stream treatment and fouling problem in membrane process, a combination pre-treatment process including ozonation, biological aerated filter (BAF) and reverse osmosis was developed for textile wastewater treatment. Comparing different ozone dosing methods, the ozone-BAF integrated device allowed a higher COD (chemical oxygen demand) and color reduction. The optimal ozone dosage in the integrated device was 20-30 mg/L After the two-stage BAF treatment, an effluent was obtained with an average COD of 27.4 mg/L, a turbidity of 4.2 NTU, a SS (suspended solid) of 3.0 mg/L, an ammonia nitrogen of 0.7 mg/L and a color of 2 degree. After being steadily treated by the reverse osmosis (RO) unit preceded by ultrafiltration, the pH value of permeate water was 7.4-7.9, conductivity was 50-200 mu s/cm, total hardness was 2-10 mg/L, and total alkalinity was 25-60 mg/L The results showed that the membrane permeates could be reused as dyeing process water. Moreover, the pH value of concentrated stream was in the range of 7.3-83, a color of 32 degree, and a COD of 45.7-97.9 mg/L. The concentrate water could be discharged directly without additional treatment since it had already met the discharge standard. (C) 2010 Elsevier B.V. All rights reserved.
