Abstract
Keksintö koskee menetelmää ja järjestelmää sulfaattisellutehtaan S/Na-tasapainon säätämiseksi, jossa rikkiyhdisteitä sisältävä sellutehtaan CNCG-virtaa (101, 201) ensin pestään vesipitoisella pesuliuoksella (109, 209), joka sisältää emäksisen aineen, jolloin saadaan vesipitoinen käytetty pesuliuos (104, 204, 204a, 20b), joka sisältää sulfideja, ja joka tämän jälkeen hapetetaan bioreaktorissa (105, 205) rikkiä hapettavien mikrobien avulla, jolloin saadaan vesipitoinen suspensio (106, 206), joka sisältää alkuainerikkiä, josta alkuainerikki voidaan erottaa saostumana (108, 208), ja jäännösliuosta (109a, 109b, 209a, 209b) voidaan käyttää vesipitoisen pesuliuoksen (109, 209) täydentämiseen.
Claims (14)
