Description
(54) СПСЮОБ ОЧИСТКИ СТОЧНЫХ ВОД ОТ КРАСИТЕЛЕЙ(54) SPSUOB TREATMENT OF WASTE WATER FROM DYES
При рН 1,0-1,5 происходит наиболее глубокое извлечение из сточной воды красителей.At a pH of 1.0-1.5, the deepest extraction of dyes from wastewater occurs.
При дальнейшем снижении рН степень очистки измен етс незначительно , а расход кислоты сильно возрастает. При увеличении рН до 2,0 остаточна концентраци красителей --возрастает в 2 раза.With a further decrease in pH, the degree of purification changes only slightly, and the acid consumption increases significantly. With an increase in pH to 2.0, the residual concentration of dyes increases by a factor of 2.
Качество окрашивани стандартным и регенерированным из сточных вод сернистым черным красителем одинаково .The quality of dyeing with sulfur black dye standard and recovered from wastewater is the same.
