Problems solved by technology

However, a large amount of flue gas will be generated during the alloy smelting process. How to deal with the flue gas to achieve energy saving and emission reduction and meet environmental protection requirements is a technical problem that we need to solve urgently
In the prior art, there are already many chemical adsorbents to adsorb pollutants in flue gas, but there are relatively few biological agents, and the effect is poor, and they cannot be applied on a large scale

Description

technical field [0001] The invention belongs to the technical field of microbes, and relates to a biological preparation for desulfurization and denitrification of flue gas from ferronickel smelting of laterite nickel ore and an application thereof. Background technique [0002] Laterite nickel ore resources are surface weathered crustal deposits formed by weathering-leaching-deposition of nickel sulfide ore rock mass. In the world, laterite nickel ore is distributed in tropical countries within 30 degrees north and south of the equator line, and concentrated in tropical-subtropical regions around the Pacific Ocean. Regions mainly include: Cuba and Brazil in the Americas; Indonesia and the Philippines in Southeast Asia; Australia, New Caledonia and Papua New Guinea in Oceania. 70% of my country's nickel ore resource reserves are concentrated in Gansu, followed by Xinjiang, Yunnan, Jilin, Sichuan, Shaanxi, Qinghai and Hubei, and the total reserves account for 27% of the count...
