  • Patent number: 11760673
    Abstract: The present disclosure relates to a treatment method of wastewater containing heterocyclic organics comprising the following steps: (1) adding a persulfate to the wastewater containing heterocyclic organics in a reaction vessel; (2) heating the reaction vessel to a reaction temperature in an inert atmosphere, then introducing an oxygen-containing gas until a reaction pressure is reached for reaction, and after the reaction is completed, cooling and filtering the reaction resultant to obtain a filtrate as a treated effluent and a filter residue; no catalyst is added to the reaction system. The treatment method provided by the present disclosure not only can significantly reduce the treatment temperature of the conventional wet oxidation, but also can control the amount of generated spherical polymer and the removal efficiency of organic pollutants by control of reaction conditions. Wastewater purification and organics recovery and reuse are achieved at the same time.
