Introduction: The waste water discharged from the PTA production unit contains pollutants such as terephthalic acid, paraxylene, methylbenzoic acid, phthalic acid, benzoic acid, methyl acetate, 4-CBA, acetic acid, cobalt, manganese, and bromine. Wastewater is usually acidic. When alkaline equipment is used to clean equipment and pipelines, it is alkaline. The CODcr and organic acid content is high. The water quality and quantity vary greatly with the operating conditions of the device, which is a relatively difficult wastewater to treat. Due to the unique water quality characteristics of PTA wastewater, and the economic and environmental value of wastewater treatment, how to effectively treat PTA wastewater has always been a concern. There are many PTA wastewater treatment technologies, which are mainly divided into physical and chemical treatment technology, biochemical treatment technology and combined physical-chemical-biochemical treatment technology.

Characteristics of PTA wastewater: High CODcr concentration and high organic acid content

Main domestic PTA wastewater treatment processes: two-stage aerobic process; anaerobic-aerobic process; other biochemical treatment processes

Overview of PTA wastewater treatment technology: Anaerobic PTA wastewater treatment technology is developing towards advanced anaerobic reactor
