    (Publishing House of Lviv Polytechnic National University, 2008) Kosogina, Iryna ; Astrelin, Igor; Klimenko, Natalya; Kontsevoy, Аndriy
    Встановлено механізм процесу очищення стічних вод від поверхнево активних речовин та сульфатно- кислотного розчинення, утвореного в результаті очищення ферумвмісного осаду. Досліджено кінетичні закономірності розчинення металовмісного осаду сульфатноюкислотою. Запропоновано кінетичне рівняння, яке адекватно описує експериментальні дані; розраховані константи кінетичного рівняння. Mechanisms of wastewater purification from surface-active substances and of sulphuric acid dissolution of iron-containing sludge formed during the previous process have been established. Kinetic regularities of metal-containing sludge dissolution in sulphuric acid have been investigated. Kinetic equation which adequately presents the experimental data has been proposed; constants of this kinetic equation have been calculated.
