Specific features of paper mill wastewater treatment

Summary

The results of the operation of local and all-factory wastewater treatment plants of a separately located paper mill using waste paper and cellulose as raw materials are considered and analyzed. The following characteristic features of the factory wastewater are indicated: significant fluctuations in flow rate and composition, high concentration of organic matter, elevated temperature, etc. The conditions for the effective operation of the local treatment facilities, including chemical treatment and two-stage pressure flotation when using waste paper and cellulose as raw materials, are noted. The unit costs and amount of effluent pollution discharged after local treatment have been determined. The data on the efficiency of the all-factory biological treatment facilities including a moving-bed bioreactor and aeration tanks, are presented. Dependencies of the main process parameters of the facilities have been obtained that provide for predicting the treatment efficiency. Measures are proposed to improve the operation of local facilities and biological wastewater treatment facilities of a paper mill.
