| titleOfInvention | Method of producing magnetite-gypsum sorbent for treating waste water |
| abstract | The invention relates to methods for producing sorbents by processing waste sulfate pickling solutions and can be used in the treatment of silicate-containing wastewater. The aim of the invention is to increase the sorption capacity of the sorbent with respect to silicate ions. For carrying out the process, iron sulfate solutions are treated with lime milk, heated and aerated, first lime milk is introduced to PH 10-11 and oxidized at 70-80 ° C to a FE 3+ / FE ratio total = 0.8-0.9, then after the introduction of the initial iron sulfate solution to a pH of 4.0-5.0 and the ratio FE 3+ / FE total. = 0.35-0.45 milk of lime is introduced to PH 7-8, and the ratio FE 3+ / FE commonly 0,66-0,70. The method allows to obtain a magnetite-gypsum sorbent, which has a 1.5 times higher sorption capacity for SI O 3 than the known sorbent, and is 204-212 mg / g. 5 tab. |
