Abstract
Przedmiotem wynalazku jest sposób wstępnej regeneracji chromowych ścieków garbarskich, obejmujący proces filtracji, w tym mikrofiltrację i ultrafiltrację. Sposób charakteryzuje się tym, że przeprowadza się następujące etapy: a) najpierw surowe ścieki garbarskie poddaje się wstępnej filtracji z eliminacją grubej zawiesiny, następnie b) otrzymany filtrat poddaje się mikrofiltracji, przy czym permeat zbiera się w zbiorniku, po czym c) otrzymany permeat poddaje się ultrafiltracji z wytworzeniem recyrkulatu chromowego, ewentualnie prowadzi się następny etap d) w którym recyrkulat chromowy poddaje się nanofiltracji.The present invention relates to a method for the pre-regeneration of chromium tanning wastewater, including a filtration process including microfiltration and ultrafiltration. The method is characterized in that the following stages are carried out: a) first, raw tanning wastes are subjected to preliminary filtration with elimination of coarse suspension, then b) the obtained filtrate is subjected to microfiltration, the permeate is collected in a tank, then c) the obtained permeate is subjected ultrafiltration to form a chromium recirculate, optionally followed by the next step d) in which the chromium recirculate is nanofiltered.
