Abstract
Inventia se refera la un procedeu de epurare avansata a apelor uzate provenite de la fabricarea celulozei sulfat, la care, în scopul îndepartarii avansate a substantelor organice din apa, efectueaza dupa decantarea solutiei tratate cu lapte de var, o oxidare catalitica catalitica în prezenta unui catalizator continînd Mn2+ si Cu2+ sub un curent de aer la 130...190 degree C.The invention relates to an advanced treatment of waste water from the production of sulphate pulp, in which, for the purpose of the advanced removal of organic substances from the water, after catalytic decanting of the solution treated with lime is carried out catalytic catalytic oxidation in the presence of a catalyst containing Mn2 + and Cu2 + under an air stream at 130 ... 190 ° C.
