Application of Microorganisms in Treating the Nitrogen-Containing Environment, Heavy Metal Water, and Sulfur-Containing Environment

Abstract

Environmental problems including nitrogen pollution, heavy metal pollution, and the air’s sulfur pollution are becoming increasingly serious nowadays, and pose a critical threat to people’s health. Utilizing microorganisms to fight pollution on account of its resistance and high efficiency to the environment. By choosing to employ nitrifying bacteria to degrade nitrogen pollution, and meanwhile, applying fungus for heavy metals absorption and using SRB for desulfurization. According to literature research, it is found that nitrifying bacteria possess the ability to degrade fast. Fungus, affected by pH, adsorption time, initial concentration, and coexisting ion concentration, can efficiently adsorb heavy metal ions. SRB, influenced by different strains, pH, and temperature, embodies higher desulfurization efficiency compared with desulfurization technologies. This work provides a comprehensive understanding of these three types of pollution and suggests microorganisms as the most efficient solutions for reducing the threat of pollution to people in the future.
