Abstract

La présente invention se rapporte au domaine de la fabrication de pâte à papier, et concerne plus particulièrement un procédé de préparation d'une liqueur de cuisson permettant d'obtenir un produit semi-fini fibreux. Ce procédé consiste à saturer, à l'aide d'une quantité d'anhydride sulfureux variant de 2,5 à 5,5 % en poids de la liqueur de cuisson et à une température de 35 à 45° C, les produits suivants: (a) soit une solution de carbonate de sodium dans des eaux usées qui proviennent de la purification biologique d'effluents industriels issus de la production de pâte à papier, et qui possèdent une concentration en boues excédentaires actives allant de 18 à 40 g/l, ladite solution possédant une concentration en carbonate de sodium de 1,55 à 2,5 % en poids en unités Na2O; (b) soit un hydrolysat alcalin obtenu par le traitement des eaux usées qui proviennent de la purification biologique d'effluents industriels issus de la production de pâte à papier, et qui possèdent une concentration en boues excédentaires actives allant de 18 à 40 g/l. Dans ce dernier cas, le traitement des eaux usées se fait à l'aide d'un mélange de base comprenant de 50 à 90 % en poids de carbonate de sodium et de 10 à 50 % en poids d'oxyde de calcium, ceci dans une quantité de 1,55 à 2,5 % en poids en unités Na2O et à une température allant de 25 à 40° C, puis à éliminer le précipité solide qui s'est formé. Ce procédé permet d'accroître sensiblement la production du produit semi-fini fibreux, d'accroître son indice physico-mécanique, ainsi que d'utiliser les déchets issus de la purification biologique des eaux usées provenant de la production de pâte à papier, et d'étendre la gamme de matières premières utilisées dans la production de liqueurs de cuisson.
