The invention discloses a resin adsorption treatment process of a high-salt wastewater containing an amine system. The resin adsorption treatment process mainly comprises the following specific steps:adjusting the pH value of raw water, feeding the adjusted raw mater into a raw water pool, pumping the raw water into a precise filter and filtering out mechanical impurities; enabling outlet water to enter a resin adsorption tower; enabling outlet water after resin adsorption to enter a resin outlet water tank, performing triple effect evaporation for evaporative crystallization and enabling mother liquid to return to a raw water buffer tank; performing desorption after adsorption, washing with water and enabling washing water to enter the raw water pool; performing desorption with methanol,evaporating desorption liquid and enabling evaporated methanol to enter a rectifying tower for refining; washing with water, feeding washing water into the rectifying tower for refining, recycling methanol at the top of the tower and feeding kettle residues into a dehydrogenation tower; enabling an ingredient at the top of the dehydrogenation tower to return to the rectifying tower and feeding kettle residues into the raw water pool. Compared with the prior art, the resin adsorption treatment process has the advantages of being low in operating cost, low in investment cost of equipment and high in removal rate, causing no secondary pollution, being cleaner, being high in selectivity and good in regeneration of the equipment and having reusability.
