Embodiment 1
[0024] A comprehensive utilization production method for treating secondary waste, including a comprehensive utilization production method for treating aluminum sludge with a brand name of HW17 and waste sulfuric acid or waste hydrochloric acid with a brand name of HW34;
[0025] In this example, the brand HW17 aluminum sludge with a water content of 72% is dried and desorbed by hot air. The hot air drying temperature is 45-60 ° C, and the drying time is 12-15 hours; after the desorption is completed, the water content is 8.6%, solid aluminum-containing sludge with an aluminum content of 98-99%, the acidity value of the solid aluminum-containing sludge after desorption is controlled to 7.8;
[0026] Add the tri(octyl-decyl)alkyl tertiary amine extractant to the waste sulfuric acid or hydrochloric acid of the brand HW34 for 3 times, the ratio of each addition is 0.6:1, and the extraction time is 3 minutes each time;
[0027] Put 0.5 tons of treated waste sulfuric acid or waste ...
