Abstract
1. Применение кремнийсодержащего белого шлама (БШ), продукта, образующегося при автоклавном удалении кремния из алюминатных растворов глиноземного производства, в качестве сорбента для очистки промышленных стоков от соединений свинца, кадмия. ! 2. Сорбент для очистки промышленных стоков от соединений свинца и кадмия по п.1, отличающийся тем, что используют кремнийсодержащий белый шлам нейтрализованный марки А, производства Богословского алюминиевого завода в виде порошка состава, мас.%: ! Оксид кремния 20-25 Оксид алюминия 25-35 Оксид железа 3-10 Оксид кальция 3-10 Оксид натрия 15-20 Оксид серы 3-6 Оксид калия 0,5-2,0 Свободная щелочь, не более 0,02 Массовая доля влаги не более 15 ! 3. Способ применения кремнийсодержащего сорбента для очистки промышленных стоков от свинца и кадмия путем введения сорбента в стоки с последующим перемешиванием и разделением жидкой и твердой фаз, отличающийся тем, что используемый в качестве сорбента кремний содержащий белый шлам вводят в массовом соотношении 5,0÷50:1 к количеству соединений свинца или 5,0÷10:1 к количеству соединений кадмия, содержащихся в сточных водах, при этом процесс сорбции с перемешиванием ведут в течение времени от 6 до 32 ч. 1. The use of silicon-containing white sludge (BS), a product formed during the autoclave removal of silicon from aluminate solutions of alumina production, as a sorbent for the purification of industrial effluents from lead and cadmium compounds. ! 2. The sorbent for cleaning industrial effluents from lead and cadmium compounds according to claim 1, characterized in that they use neutralized silicon-containing white sludge of grade A, produced by the Bogoslovsky Aluminum Plant in the form of a powder composition, wt.%:! Silica 20-25 Alumina 25-35 Iron oxide 3-10 Calcium oxide 3-10 Sodium oxide 15-20 Sulfur oxide 3-6 Potassium oxide 0.5-2.0 Free alkali, not more than 0.02 Mass fraction of moisture no more than 15! 3. The method of using a silicon-containing sorbent for cleaning industrial effluents from lead and cadmium by introducing a sorbent into the effluent, followed by mixing and separation of the liquid and solid phases, characterized in that the silicon containing white sludge used as the sorbent is introduced in a mass ratio of 5.0 ÷ 50 : 1 to the number of lead compounds or 5.0 ÷ 10: 1 to the number of cadmium compounds contained in wastewater, while the sorption process with stirring is carried out over a period of 6 to 32 hours.
