摘要： 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.

摘要： Disclosed is a method for degrading antibiotics by aqueous phase transfer catalysis using an anionic liquid and hydrogen peroxide, including: adding hydrogen peroxide to a wastewater containing the antibiotics to obtain a first mixture, and adjusting a pH of the first mixture to 3-4 to form an aqueous phase, and adding a catalyst to a water-insoluble ionic liquid to obtain a second mixture, and stirring the second mixture to form an ionic liquid phase, wherein the catalyst is selected from the group consisting of ferrocene, iron dodecyl sulfonate, ferrous dodecyl sulfonate, and copper dodecyl sulfonate; and mixing the aqueous phase and the ionic liquid phase in a volume ratio of (8-11):1 to obtain a mixed phase, and stirring the mixed phase to degrade the antibiotics.
