Research on the Causes and Solutions of Hydrogen Sulfide Production in Activated Carbon Adsorption Tower
A certain mine adopts the basic process of"neutralization and filtration of carbide slag-adsorption and oil removal of filtrate activated carbon" in the water treatment process.Analysis and research were conducted on the actual problem of hydrogen sulfide generation in its activated carbon adsorption tower.The results showed that the growth and reproduction of SRB in the tower were the direct cause of hydrogen sulfide gas generation,and it was found that the source of SRB bacteria was caused by the return of domestic sewage.A strain of SRB was isolated from the water body adsorbed by activated carbon.The growth and reproduction of this strain are influenced by environmental factors such as pH value,temperature,oxygen,Fe2+,and carbon source,among which pH value and temperature are important factors affecting the growth and reproduction of SRB.Based on the actual situation on site,the advantages and disadvantages of the available treatment measures were compared and analyzed.Through heat treatment treatment,the growth of bacteria was effectively suppressed,achieving the treatment effect.
