High-concentration salt-containing organic waste water catalytic oxidation treatment process and system

The invention discloses a salt-containing organic waste water efficient contact oxidation treatment process and system, for treating the salt-containing waste water with high concentration of organic contaminants generated in an electroplating, hydrometallurgy and extraction processing industryindustries. The process comprises the following steps: (1) performing solid-liquid separation for salt-containing organic waste water, and adjusting the pH of the waste water to be 3 to 5; (2) adding a surface accelerant into the waste water, and introducing oxygen to have the homogenizing reaction; (3) after the homogenizing reaction is ended, adding a breaking agentPPL and an oxidant, and enabling an organic complex to have oxidation complex breaking reaction; (4) after the oxidation complex breaking reaction, adjusting the pH value of the salt-containing organic waste water to be 8 to 9, and co-precipitating the generated flocculating constituent; and (5) after the reaction, performing the solid-liquid separation, an
