Wastewater treatment equipment of pulp and paper mill

 

 

 

The paper industry has a large amount of wastewater discharge and high pollutant content. The wastewater contains a lot of hemicellulose, lignin and chemicals, and the oxygen consumption is high.

 

Papermaking wastewater mainly comes from the stages of material preparation, pulping, washing, screening, bleaching and papermaking, including material preparation wastewater, pulping wastewater, intermediate stage wastewater, sewage Cooling Wastewater and papermaking wastewater. The main goal of treatment is to reduce COD, BOD and SS in wastewater to meet the discharge standard.

 

The pollution control methods of pulping and papermaking wastewater can include physical method, chemical method, physicochemical method and biological method.

 

The effluent quality of pulping and papermaking wastewater is clear and can be reused.
