Zusammenfassung: | A method for removing hydrogen sulfide gas by utilizing biological active carbon fiber is characterized in that a nutrient fluid spray header communicated with external nutrient fluid is arranged at the upper part of the inner chamber of a biological packing tower, the middle part of the inner chamber is filled with active carbon fiber, and gas containing hydrogen sulfide is fed to the lower part; before being used, the biological packing tower needs to be treated through biofilm domestication, namely, in the first two days, the gas containing hydrogen sulfide is not fed, but nutrient fluid is sprayed to the active carbon fiber through the spray header to enable microbe to be adhered to the active carbon fiber, and the gas containing hydrogen sulfide is fed in the third day, wherein the gas inflow is controlled to be 40 to 60 L/h, the pH value of the nutrient fluid is 2 to 5, the temperature is 30 to 38 DEG C, and the time is 8 to 10 days. According to the invention, absorbent carbon fiber is used as stuffing |
