该专利涉及一种精对苯二甲酸(PTA)精制废水的资源化综合利用技术。具体方法如下:将PTA精制废水依次经过阳离子交换器和3级选择性吸附器,得到纯化水;待阳离子交换器和3级选择性吸附器饱和后分别解析;从阳离子交换器的解析液中回收钴和锰,钴回收率为90%,锰回收率为75%;从第1级选择性吸附器的解析液中回收对甲基苯甲酸、对苯二甲酸和苯甲酸,对甲基苯甲酸 The patent relates to a refined terephthalic acid (PTA) refined wastewater comprehensive utilization of resources technology. The specific method is as follows: the PTA purified wastewater is passed through a cation exchanger and a 3-stage selective adsorber in order to obtain purified water; the cation exchanger and the 3-stage selective adsorber are respectively analyzed after being saturated; and the recovered solution is recovered from the cation exchanger Cobalt and manganese, 90% cobalt recovery and 75% manganese recovery; p-methylbenzoic acid, terephthalic acid and benzoic acid were recovered from the first stage selective adsorber analytical solution, p-methylbenzoic acid
