Abstract

In this study, we used the ultrasound/hydrogen peroxide (^Oi) process to treat the pure terephaltic acid (PTA) industrial wastewater. The BODy and TOC of raw PTA wastewater were 13,200 and 6,390 mg/L, respectively. Several semi- and non-volatile organics, such as benzoic acid, 4-methyl benzaldehyde, phenyl acetic acid, and 4-ethyl bem^oic acid were detected in PTA wastewater by GCD (HP GCD 1800A). In the present paper, we discussed the effect of ultrasound/ H:O] process with various concentrations of ItO: and pH values on mineralization and biodegradability of PTA wastewater. Mineralization of PTA wastewater was evaluated by the ratio of TOC removal, and biodegradability by real residual BODs over theoretical residu
