Abstract
1. Способ очистки медьсодержащего сульфидно-щелочного смешанного стока, содержащего в том числе сток производства акриловой кислоты, включающий реакционную обработку стока углекислым газом.2. Способ очистки по п. 1, отличающийся тем, что реакционную обработку углекислым газом ведут с получением стока, имеющего рН от 7,0 до 10.3. Способ очистки по п. 1, отличающийся тем, что углекислый газ подают в количестве не менее 1 кг на 1 т смешанного стока.4. Способ очистки по п. 1, отличающийся тем, что реакционную обработку стока осуществляют при абсолютном давлении не менее 0,2 МПа и температуре не более 98°С.5. Способ очистки по п. 4, отличающийся тем, что реакционную обработку стока осуществляют при температуре 30-85°С.6. Способ очистки по п. 1, отличающийся тем, что реакционную обработку осуществляют либо противоточной абсорбцией в колонне, либо перемешиванием потоков смешанного стока и углекислого газа в смесителе, либо введением углекислого газа в трубопровод подачи смешанного стока, либо пропусканием через сток потока газа.1. A method of purifying a copper-containing sulfide-alkali mixed effluent, including including an acrylic acid production effluent, comprising reacting the effluent with carbon dioxide. The purification method according to claim 1, characterized in that the reaction treatment with carbon dioxide is carried out to obtain a runoff having a pH of from 7.0 to 10.3. The cleaning method according to claim 1, characterized in that carbon dioxide is supplied in an amount of at least 1 kg per 1 ton of mixed effluent. 4. The cleaning method according to claim 1, characterized in that the reaction treatment of the effluent is carried out at an absolute pressure of not less than 0.2 MPa and a temperature of not more than 98 ° C. 5. The cleaning method according to claim 4, characterized in that the reaction processing of the effluent is carried out at a temperature of 30-85 ° C. 6. The purification method according to claim 1, characterized in that the reaction treatment is carried out either by countercurrent absorption in the column, or by mixing the flows of mixed effluent and carbon dioxide in the mixer, or by introducing carbon dioxide into the mixed effluent supply pipeline, or by passing a gas stream through the effluent.
