Embodiment 1
[0031] Embodiment 1 has the following steps:
[0032] A. Mechanical crushing: use a crusher to pulverize the bioleaching sludge with a moisture content of 50%, the particle size of the pulverized bioleaching sludge is less than 5.0mm, and the organic matter content in the bioleaching sludge is 30%;
[0033] B. Sludge conditioning: add lime according to 0.8% of the dry weight of the above-mentioned bioleaching sludge, and adjust the pH value of the bioleaching sludge to 5.0; meanwhile, add auxiliary materials according to 4% of the wet weight of the bioleaching sludge, The auxiliary material for adjusting the porosity is a mixture of straw and mushroom slag, and the porosity of the bioleaching sludge is adjusted to 55%, and the conditioned bioleaching sludge is used as a fermentation raw material, and the organic matter content of the above fermentation raw material is controlled at 30%;
[0034] C. Reactor fermentation: inoculate the sludge fermentation agent according to 1.5‰...
