description The invention discloses a coupling treatment method of a high-salinity high-chroma hydrothermal solution, and relates to the technical field of hydrothermal. The method comprises the steps of ozone pretreatment and electrodialysis treatment. According to the ozone pretreatment, an ozone generator in a laboratory is adopted to carry out related experiments, and decomposition, decoloration and conversion mechanisms of factors such as ozone contact time, pH value, ozone concentration and ionic strength on organic matters in the hydrothermal solution are explored through a single-factor control variable method. By adopting ozone pretreatment, the degradation efficiency of macromolecular substances can be remarkably improved, and the service life of a membrane assembly in the electrodialysis process is further prolonged; by adopting an ozone pretreatment coupling electrodialysis combined process, the problem of membrane pollution and blockage in a single electrodialysis treatment process is effectively solved, eff
