description The invention relates to a process and a system for treating wastewater containing salt and mixed acid. The process comprises the following steps: primary evaporation; performing extraction; performing secondary evaporation; and centrifuging. The system comprises: a wastewater storage tank; the evaporation tower is communicated with the wastewater storage tank and is used for carrying out primary evaporation and secondary evaporation on the wastewater; the cooling tower is communicated with the upper outlet of the evaporation tower and is used for performing low-temperature condensation on steam at the upper outlet of the evaporation tower; the extraction separator is communicated with the lower outlet of the evaporation tower and is used for extracting a primary concentrated solution obtained by primary evaporation at the lower outlet of the evaporation tower; a centrifugation unit; and a storage unit. Compared with the prior art, resource utilization of wastewater and waste liquid can be realized, the chemi
