生物法去除厌氧发酵所产沼气中的H2S
Hydrogen sulfide removal from biogas in anaerobic fermentation by use of biological process
摘要
Abstract
The biological removals of hydrogen sulfide are experimentally studyied from biogas in anaerobic fermentation.The experimental results indicate that the optimum level of spray liquid flow rate,H2S inlet concentration,reaction temperature,air intake flow and dissolved oxygen are respectively 40 mL · min-1,3 000 mg · L-1,31 ℃,120 mL · min-1,0.5 mg · L-1.When the reaction temperature is 31 ℃ and the dissolved oxygen concentration is 0.5 mg · L-1,to the order of primary and secondary factors are determined as air intake flow,spray liquid flow rate,H2S inlet concentration through the orthogonal experiment,with their optimum level 60 mL · min-1,60 mL · min-1 and 1 500 mg · L 1 respectively.Under the optimum conditions,the biological removal rate of H2S is stable amounting to 100％.关键词
