| Zusammenfassung: | The invention provides a biological treatment system for waste gas, which solves the problems of higher operating cost, complicated operation and low removal rate of a conventional waste gas desulfurization technology. The technology disclosed by the invention adopts higher pH, higher alkalinity and microbial resources of activated sludge of an aerobiotic system to spray and wash the waste gas, the deodorization efficiency and sulfuretted hydrogen removal rate are high, a washing liquid returns the aerobiotic system, sulfuretted hydrogen is converted into sulfate radical to be removed through a conventional aeration facility. The technology is simple to operate, low in operating cost and very suitable for waste gas treatment, and the efficiency is stable and guaranteed. |
