- Abstract
The study shows that there will be a good effect to degrade printed circuit board(PCB) waste stripping liquid using UV/Fenton homogeneous photochemical catalysis system.The removal rate of COD could reach 80% at the conditions with double dose of H_2O_2,1:20 mol ratio of Fe~(2+):H_2O_2 and 80min hydraulic retention time(HRT).In all influential factors the H_2O_2 dosing ratio is the most important by order,then follows the ratio of FeSO_4/H_2O_2,and at last the illumination time.
