| Abstract: | An improved oxidation ditch process using forced air supply low-pressure jet aeration system was used to treat middle-stage wastewater from pulping and papermaking.The whole commissioning of the process is introduced.The operation results indicated that the process has rational design and the system has stable and reliable operation.The effluent COD,SS and BOD5,are less than or equal to 150 mg/L,80 mg/L and 80 mg/L respectively,and their removal rates are all higher than 85%.The effluent quality meets the D... |
