  WASTE WATER TREATMENT OF PAPERMAKING INDUSTRY
       
 

 

The waste water is mainly composed of black liquor from pulp- extruding, black mediate section water from pulp-washing, white mediate section water and discharging white liquor from bleaching machine. The project consist of Alkali Recovery Workshop and Mediate Water Treatment. Alkali recovery workshop includes abstract section, evaporating section, combustion section and causticizing section. Mediate water treatment includes mediate water advance precipitation, adjustment, fibre recovery, mixture reaction, precipitation, oxidation, sludge do-water.
