Through the analysis of the content of the paper mill midcourse wastewater quality characteristics, bined with this kind of wastewater treatment process and specific requirements of factory environmental hygiene requirements and the project of the Carrousel oxidation ditch process is the core process, using the design of sewage treatment technological process for grid of regulating tank, flocculation and sedimentation tank, hydrolysis acidification pool Carrousel oxidation ditch, secondary sedimentation tank, sludge thickening tank the sludge dewatering. Its effluent quality: COD:, BOD5:, pH:69, SS:requirements of the GB35442020 paper industry water pollution discharge standards. The design flow technology is mature, practical, reliable operation, simple operation, low operating expenses, small area of area.
