摘要： 在氧化亚铁硫杆菌(T.f)培养过程中其他营养物质足量的情况下，考察了活性炭的质量浓度对T.f菌生长活性的影响，得到在不同活性炭质量浓度下细菌的生长曲线.结果表明:在一定范围内，活性炭对T.f菌的氧化活性具有一定的促进作用；当活性炭的质量浓度≤80g/L时，其对细菌氧化活性具有促进作用，且当其在60~80g/L范围内时，对细菌氧化活性的促进作用最大；但当活性炭的质量浓度≥100g/L时，细菌生长受到抑制.并通过考查无菌对照实验中ρ(Fe2+)，ρ(Fe3+)随时间的变化，得出在活性炭的质量浓度≤80g/L时，其对Fe2+的氧化作用很小.

Abstract: When other nutrients were sufficient in cultivation of the thiobacillusferrooxidans， the effect of mass concentration of activated carbon on the growth activity of thiobacillusferrooxidans was studied， and the bacterial growth curves were obtained at different activated carbon mass concentrations. The experimental results showed that the activated carbon can promote the oxidative activity of thiobacillusferrooxidans in a certain concentration range. When the activated carbon concentration is less than 80g/L， it has a promoting effect on bacterial oxidative activity; when the concentration is 60~80g/L， the promoting effect is the biggest; when the concentration is larger than 100g/L， the growth of thiobacillusferrooxidans is completely inhibited. By researching the timevariation of ρ(Fe2+) and ρ(Fe3+) during the sterile control experiment， the results showed that the activated carbon has little effect of oxidation on Fe2+when the activated carbon concentration is less than 80g/L.

Key words: thiobacillusferrooxidans, oxidative activity, activated carbon, adsorption, catalytic oxidation
