This paper studies the effectiveness of the "O3-BAC" composite process in the treatment of the reverse osmosis concentrate of the PTA wastewater, and provides an important basis for the industrialization practice of the treatment of the reverse osmosis concentrate of the PTA wastewater.A pilot test was conducted in a petrochemical PTA sewage treatment plant in JiangSu province using the ozone-biological activated carbon combination process, to investigate the effect of the process on the deep treatment of PTA reverse osmosis concentrated water under the design parameters.The experiment showed that when the pH was 8 ~ 9, the ozone injection amount was 60mg/L, the oxidation contact time was 90min. the BAC adsorption time was 60min.after processing, the CODCr is less than 60mg/L. The effluent quality can meet the direct emission standard of petrochemical industry GB31571-2015.The experimental results show that the combination process is stable for the treatment of reverse osmosis concentrate of the PTA wastewater.
