Abstract: 

This study was performed to assess the petrochemical wastewater containing Terphthalic acid for discharge to the environment and reuse it. In this project, the ozonation process was used for the degradation and mineralization of the wastewater containing 60 mg 1-1 of Terphthalic acid in semi-continuous reactor under the variable amounts of ozone and pH. The ozonation process is performed at pH of 5, 7, 9 and 11. After 30 min of the treatment process, at pH of 9 and the optimal level of ozone concentration (8.6 mg/L) the degradation of the pollutant was about 99.3% and at a pH of 5, 7 and 11, the amount of degradation was 79.7, 90.5 and 93%, respectively. Results showed that the formation of hydroxyl radical was more at alkaline than acidic media. The removal rate decreased significantly by increasing the concentration of the Terephthalic acid. About, 58.5% of chemical oxygen demand (COD) is removed at pH of 9 and 90 min of reaction. The removal rate of Terphetalic acid was more than the removal of COD, because the produced intermediate compounds were resistant against degradation. The degradation rate of pollutants was pseudo first order, and the rate constant (k) and the half-life time of reaction (t2.1) were determined.
