<p>An organic wastewater recycling treatment method is provided, in which the organic wastewater is treated by the steps of primary settling, anaerobic treating, flocculating, biological oxidizing, coagulating, photocatalysis oxidizing, flocculating and decolorizing, sand filtering, modified active carbon absorbing, sterilizing and active carbon absorbing. The treated wastewater meets the use standard of the printing and dyeing process, thereby saving a great deal of water resource. Biogas produced in the process of wastewater treatment is collected for generating electric power, thereby guaranteeing self-operation of system. The sludge is used as boiler fuel, thereby saving the operation cost of printing and dyeing enterprises, and avoiding secondary pollution caused by sludge landfill.</p> |
