摘要： A method for recovering water from purified terephthalic acid production wastewater includes: producing purified terephthalic acid comprising purified terephthalic acid feedstock and wastewater comprising impurities; separating the purified terephthalic acid feedstock from the wastewater comprising impurities; transferring the wastewater to a tank; adjusting the p H of the wastewater with a basic solution; adjusting the temperature of the wastewater; passing the wastewater to a column; contacting the wastewater with an ion exchange resin to remove the impurities; and recovering the water depleted of impurities.
