Abstract: The present disclosure discloses a method and device for removing Organic Micropollutants (OMPs) in water, and belongs to the technical field of wastewater treatment. The method includes the following steps: S1: aerating residual sludge under a starvation condition to enrich starved-state microorganisms; and S2: treating wastewater containing OMPs under an aeration condition with sludge containing the starved-state microorganisms obtained in step S1, and periodically updating the sludge containing the starved-state microorganisms. According to the present disclosure, aerobic starvation treatment is performed on the sludge to gradually reduce the abundance of microorganisms that may use degradable organic matters only and enrich microorganisms that may use complex organic matters in the sludge, and the enriched sludge may degrade various OMPs and be used to remove OMPs in wastewater. The process is easy to operate and low in cost and has relatively high practical application value.
