The present application relates to the field of wastewater treatment, and more particularly, to a method and device for treating laundry wastewater. One of the laundry wastewater treatment methods includes four steps: primary sedimentation, oxidation treatment, secondary sedimentation, and filtration. The COD value of the treated wastewater can be effectively reduced through the four steps. In addition, the present application relates to a Chinese laundry wastewater treatment device, including a primary sedimentation tank, an oxidation tank, a sedimentation tank and a filter device, for the treatment of laundry wastewater. The organic matter content in the treated laundry wastewater is greatly reduced, and the COD value is significantly reduced. Can be directly reused or discharged. |
