Description

technical field [0001] The invention relates to the technical field of waste acid treatment, in particular to iron-containing waste acid treatment equipment with multiple aeration discs. Background technique [0002] The main component of iron-containing waste acid is ferrous chloride or ferrous sulfate. The technology of producing spherical iron ferric oxide by using waste acid as raw material has been developed. This technology can convert iron ions in waste acid Become ferric oxide with high added value. However, in the prior art, since there is no special synthesis processing equipment, the synthesis of ferroferric oxide is relatively cumbersome, and it needs to be synthesized on different reaction equipment, resulting in low synthesis efficiency of ferric oxide, complex and cumbersome procedures , The equipment affects the space utilization rate and labor-intensive problems in the workshop. Contents of the invention [0003] The object of the present invention is to...
