Method and device for removing organic micropollutants (OMPs) in water

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.

Method of treatment of water effluent with multilayer filter under electric current

A method and system treating aqueous effluent from an aqueous stream from at least one of a manufacturing facility, compounding facility or municipal water treatment facility. Reductive and/or oxidative chemical species in an aqueous fluid stream decompose natural hormonal or synthetic hormonal contaminants. The method includes: providing a filter material comprising at least one porous carbon support layer and a silicate wool or glass wool layer in direct contact with the at least one porous carbon support layer having distributed halogens or halides within; passing an electric current through the filter material while directing a contaminated aqueous mass comprising natural hormonal or synthetic hormonal contaminants into contact with the filter material; and adsorbing the hormonal contaminants from the fluid mass onto the filter material in the presence of the electric current, and decomposing the hormonal contaminants.
