Papermaking wastewater treatment

    Papermaking wastewater treatment:

    Papermaking wastewater is mainly produced in the pulping and paper picking processes of papermaking industry. Pulping is to separate the fiber in plant materials to produce sizing agent to be bleached. This process produces a large amount of papermaking wastewater. Paper picking is to dilute, mold, press, and dry the sizing agent to produce paper. This process is also prone to cause papermaking wastewater. 

    Common treatment methods: reverse osmosis, ultrafiltration method, electrodialysis method and so on 

     

    Project example: Gold Hongye Paper's papermaking wastewater treatment project 

    Designed duty of water: 22000m³/D

    According to the incoming water quality table, it is can be seen that CODcr≤1000 Mg/l/1, BOD5≤400 Mg/l, and B/C=0.4. The sewage biodegradability is good and can be directly treated by using biochemical method. 

    The SS content in wastewater is high. Without being pretreated, the SS content can increase the subsequent biochemical treatment load. Therefore, the wastewater shall be pretreated to remove most SS before entering the biochemical system.
