METHOD FOR WET REMOVAL OF SULFUR DIOXIDE BY SILICATE BACTERIA-ENHANCED PULP

The present disclosure provides a method for wet removal of sulfur dioxide by silicate bacteria-enhanced pulp. The method includes: treatment of ore waste residue, activation and domestication of silicate bacteria, preparation of pulp, removal of sulfur dioxide, and resource utilization of a desulfurization product. The present disclosure combines flue gas desulfurization with resource utilization of the ore waste residue, and improves a desulfurization efficiency of the method by the pulp and a utilization rate of ore waste residue resources through silicate bacteria. The present disclosure has a high desulfurization efficiency, simple production process, and low cost, and realizes the recycling of resources such as the ore waste residue, the sulfur dioxide, and silicon. The present disclosure has obvious economic and environmental benefits and broad prospects for use.
