| Abstract: |
| In this work, 100% resource utilization of high salt and high chemical oxygen demand（COD）
wastewater from hyposulfonamide accelerator production was achieved by organically combining the resin
adsorption process，catalytic wet oxidation process，ozone oxidation process and evaporation concentration
process.The wastewater treatment steps were as follows：Organic amine raw materials in the production
wastewater were absorbed and recovered by resin adsorption，COD was reduced by catalytic wet oxidation
and ozone oxidation，then the heavy metal ions，calcium ion and magnesium ion were removed by multi-stage
resin adsorption，and at the last step，evaporation concentration was carried out.The obtained treated water
met the primary influent standard of ion-exchange membrane caustic soda.With this process，zero emission of
wastewater from accelerator production was realized. |
