Abstract

The invention relates to the paper pulp industry, specifically to a process for preparing a pulp cooking solution used for obtaining a fibrous semi-finished product. This involves saturating a solution of sodium carbonate in waste water obtained from the biological purification of paper industry effluent with a concentration of surplus active sludge of 18-40 g/l, having a sodium carbonate concentration of 1.55-2.5 wt.% in units of Na2O, or an alkaline hydrolysate obtained by treating waste water obtained from the biological purification of paper industry effluent with a concentration of surplus active sludge of 18-40 g/l with a mixed base containing 50-90 wt.% sodium carbonate and 10-50 % calcium oxide, in a quantity of 1.55-2.50 wt.% per unit Na2O at a temperature of 25-40 °C with subsequent removal of the solid precipitate, at a temperature of 35-45 °C until it accounts for 2.5-5.5 wt.% of the cooking mixture. The proposed process significantly increases the yield of fibrous semi-finished product and improves its physical and mechanical indicators. It also permits the use of waste obtained from the biological purification of paper industry effluent and widens the range of raw materials which can be used to produce pulp cooking solutions.
