The wastewater treatment method of paper machine should adopt different wastewater treatment methods according to different production processes and different production conditions.
Paper machine's wastewater treatment should focus on increasing the rate of recycling water, while reducing water consumption and wastewater discharge, reducing production costs and decontamination costs in all aspects. Different paper machine production processes can be processed according to local conditions, which can greatly improve the processing efficiency.
When treating paper machine kraft paper wastewater, BOD can be removed by biophysical methods, and wet oxidation can be used to treat sulfite pulp wastewater. Of course, the domestic treatment methods are different. Generally, reverse osmosis, ultrafiltration, and ultrafiltration are used. Wastewater treatment methods such as electrodialysis.
