Coalescence technology for removing CPMABA in PPS brine

The invention discloses a coalescence technology for removing CPMABA in PPS saline water, which comprises the following steps: S1, taking the PPS saline water containing CPMABA, and adjusting the pH value of the PPS saline water to be acidic to obtain pretreated PPS saline water; and S2, introducing the pretreated PPS saline water into a coalescence device for coalescence treatment. The coalescence technology disclosed by the invention can efficiently and stably remove the CPMABA impurity in the PPS brine, and improves the quality of the byproduct salt. 本发明公开了一种去除PPS盐水中CPMABA的聚结技术，包括如下步骤：S1、取含有CPMABA的PPS盐水，并将其pH值调节至酸性，得到预处理后的PPS盐水；S2、将预处理后的PPS盐水通入聚结装置中进行聚结处理。本发明公开的聚结技术可以高效、稳定地去除PPS盐水中的CPMABA杂质，提高副产盐的品质。
