APPARATUS FOR INGREDIENT ANALYSIS OF WASTEWATER CONTAINING PURITY TEREPHTALIC ACID AND METHOD OF INGREDIENT ANALYSIS USING THE SAME

摘要

An apparatus for analyzing the wastewater containing terephthalic acid of high purity, and its method are provided to measure the concentration of terephthalic acid, acetic acid, benzoic acid and p-toluene acid contained in the wastewater generated in the manufacturing process of terephthalic acid simultaneously. An apparatus for analyzing the wastewater containing terephthalic acid comprises a pretreatment device(120) which removes the float of the wastewater obtained in the manufacturing process of terephthalic acid; a spray pump(140) which transfers the pretreated wastewater; a spectrophotometer(160) which measures the absorbance of the transferred wastewater; a PC(180) which stores the transmitted data of the absorbance of the wastewater and calculates the concentration of the wastewater by using the measured data; and a control and signal transmission unit(200) which transmits the concentration of the wastewater to a dispersion control system.
