| description | The invention belongs to the technical field of aluminum alloy die application, and particularly discloses a novel treatment method for recycling aluminum material rotten die alkali washing wastewater, which comprises the following steps: step 1, alkali washing; step 2, filtering and removing impurities; step 3, adjusting the parts; step 4, seed crystal decomposition; and step 5, filtering and washing, and separating and washing the aluminum hydroxide to obtain regenerated sodium hydroxide. The treatment method has the beneficial effects that aiming at the defects of the prior art, the problems of high alkali consumption, small aluminum recovery amount, low safety and the like in a mold treatment process of an aluminum alloy manufacturer are fundamentally changed, and the novel treatment method for recycling the aluminum product mold rotting alkali washing waste water is provided, wherein the alkali washing wastewater is treated, the sodium hydroxide liquid and the aluminum hydroxide are separated out through |
