  • Can lignin be depolymerized in papermaking wastewater?
  • Fourthly, the high temperature, high pH, and a large number of other toxic substances of papermaking wastewater afect the depolymerization of lignin. Therefore, it is more advantageous to explore methods that are resistant to poison, high temperature, and alkali conditions for lignin treatment in papermaking wastewater.
  • Can physicochemical treatment of papermaking wastewater improve its treatment efficiency?
  • Therefore, exploring the appropriate coupling method to treat papermaking wastewater might improve its treatment efficiency. However, the existing physicochemical treatments of papermaking wastewater are of high cost and low efficiency and easily resulted in secondary pollution.
  • How can a micro-physicochemical process improve pulp and paper industry wastewater?
  • There is rapid improvement in the new technology/process development due to the necessity of treating pulp and paper industry wastewater. Combining the micro-physicochemical process, modification, or hybrid of the existing process will reduce the contaminants and improve treated water quality for reuse.
  • Can lignin biodegradation reduce Cod and chroma in papermaking wastewater?
  • Therefore, lignin biodegradation in papermaking wastewater could reduce the COD and chroma of wastewa-ter, thereby obtaining high value-added products and maxi-mizing the resource utilization process. Overall, the conversion of lignin into value-added prod-ucts by bioremediation has substantial prospects.
