Abstract

Det beskrives produksjon av tremasse og papir, spesielt en fremgangsmåte for fremstilling av masse-kokevæsker for produksjon av et fibrøst halvfabrikat. Det beskrives en kokevæske som fremstilles ved metning av et vannmedi- um med svoveldioksid forutsatt at dette vannmedium faktisk er enten et masse- og papirmølle-avfallsvann med aktivert slam (18-40 g/l) og natriumkarbonat (1,55- 2,50 vekt%) i det eller alkalihydrolysat produsert ved behandling av det samme avfallsvann ved hjelp av en blanding av basesalter som inneholder natriumkarbo- nat (50-90 vekt% basert på Na20) ved temperatur 25-40°C fulgt av fjerning av et fast sediment, og metningen går videre inntil en konsentrasjon av svoveldioksid i væsken på 2,5-5,5 vekt%. Den beskrevne fremgangsmåte gjør det mulig i betydelig grad a øke pro- duksjonen av et fibrøst halvfabrikat og forbedre dets mekaniske egenskaper og også å utnytte avfallsvann som er generert ved et anlegg for behandling av av- fallsvann fra en masse- og papirmølle og å ekspandere en kilde for råmaterialer som trenges for fremstilling av kokevæsker.There is disclosed the production of wood pulp and paper, in particular a process for the production of pulp boiling liquids for the production of a fibrous semi-finished product. A boiling liquid is described which is prepared by saturating a water medium with sulfur dioxide, provided that this water medium is in fact either a pulp and paper mill waste water with activated sludge (18-40 g / l) and sodium carbonate (1.55-2.50 wt%) in the alkali hydrolyzate produced by treating the same wastewater using a mixture of base salts containing sodium carbonate (50-90 wt% based on Na 2 O) at temperature 25-40 ° C followed by removal of a solid sediment , and the saturation proceeds until a concentration of sulfur dioxide in the liquid of 2.5-5.5% by weight. The described process allows to significantly increase the production of a fibrous semi-finished product and improve its mechanical properties and also to utilize the waste water generated by a waste water treatment plant from a pulp and paper mill and to expand one. source of raw materials needed for the production of boiling liquids.
