Abstract
The invention discloses a method for treating a waste catalyst containing copper, cobalt and nickel and a homogenizing device thereof, and relates to the technical field of waste catalyst treatment.The method comprises the following steps that firstly, strains suitable for growing and breeding in a waste catalyst environment are obtained, autotrophic thiobacillus and iron-oxidizing bacteria are domesticated through the ground waste catalyst, and the strains are obtained; and heterotrophic mould; 2, a reaction tank is prepared, a framework is arranged in the tank, a plurality of trays are placed on the framework, water permeable holes are formed in the bottoms of the trays, non-woven fabric is laid on the water permeable holes, air pipes are laid on the non-woven fabric, and holes are formed in the air pipes at intervals; according to the method, the copper-containing, nickel-containing and cobalt-containing waste catalyst is treated by a biological method, the waste catalyst is decomposed by bacteria, and the valuable metals in the waste catalyst are recovered by resin adsorption, precipitation, extraction and the like, so that the method has the advantages of low cost, low investment, simplicity in operation, low energy consumption, high valuable metal recovery capacity, no toxic by-product generation and the like on the whole.
Description
technical field [0001] The invention relates to the technical field of waste catalyst treatment technology, in particular to a method for treating waste catalyst containing copper, cobalt and nickel and a homogenizing device thereof. Background technique [0002] In addition to platinum, palladium, silver and other precious metals, the metals used for catalysts are: nickel, cobalt, vanadium, tungsten, molybdenum, chromium, copper, zinc, bismuth, titanium and rare earth metals, etc. With the increasingly widespread application of catalytic technology in various sectors of industry, the number of various solid waste catalysts replaced every year is also increasing. The recovery of the above metals from waste catalysts can not only turn waste into wealth, but also play a role in increasing revenue and reducing expenditure. To eliminate the environmental pollution caused by the stacking of spent catalysts, many industrially developed countries have developed and utilized solid w...
