Keywords: | Wastewater treatment;Divalent sulph;Pollution | Issue Date: | 30-Nov-1982 | Abstract: | Waste waters and gases contaminated with divalent S cpds. are purified by treatment with an inorganic Cu, Fe and Ni salt catalyst in ratio 0.01-10: 0.15-15:05, expressed in g/l, at NTP, for 30-60 mins. The recovered catalyst is then recycled. Before contact with catalyst, residual waters are set to pH 3.5-6.5 with H2SO4. After contact, they are basified with alkaline hydroxides at pH 7-10 and decanted. |
