About the paper industry wastewater and waste sludge treatment

Paper industry using wood, straw, reeds, rags as raw materials, high temperature and high pressure cooking and separation of cellulose, made of pulp. In the production process, the wastewater mainly from pulp and papermaking two production processes
Pulp, papermaking are discharged a lot of waste water. Pulping waste water, the most serious pollution. Washing waste water was dark brown, known as black water, black water, high concentrations of pollutants, containing a large number of fibers, inorganic salts and pigments. Bleaching process waste water also contains a large number of acid-base substances. Paper machine discharge of wastewater, known as white water, which contains a lot of fiber and in the production process to add filler and compound.

Wastewater treatment process: Wastewater into the wastewater treatment system, the first trash rack to remove large debris, and then enter the adjustment pool, in the regulation pool, the mixer to the full mixing and mixing to balance water quality, and then enter the beginning Sedimentation tank to gravity sedimentation, removal of SS and some of the wastewater BOD, COD, and then by the sewage pump to the cooling tower to enhance the water temperature to 35 ℃ below the water into the A / O pool and biological contact oxidation tank, To remove most of the BOD and COD, sedimentation tank upper water overflow into the tertiary treatment system - coagulation reaction tank, by adding PAC and coagulation tank reactor mechanical coagulation under the action of coagulation, precipitated effluent into the factory Total Exhaust.
The sedimentation sludge, the secondary sedimentation tank sludge, the tertiary sedimentation tank sludge and the final settling tank sludge are partially refluxed, and the rest are sent to the sludge thickening tank, which is dehydrated and squeezed into sludge cake by the sludge dewatering machine (water content 70 %) After Sinotrans

The belt filter press is used in the sludge sewage squeezing link, the sludge dehydration into the filter cake
