摘 要: 考察低分子有机酸、醇类、挥发性脂肪酸盐和糖类等作为SRB碳源时对硫酸盐去除效果的影响。结果表明：在不同碳源培养基中，SRB的生长速率存在明显差异，SRB对于碳源的利用率由大到小依次为：低分子有机酸、挥发性脂肪酸盐、醇类、糖类；综合硫酸根去除效果和操作成本，价廉的甲酸可作为硫酸盐还原菌生物还原工艺的首选碳源，硫酸盐去除率可高达97%。

Abstract:The influence of various carbon sources on the growth and activity of SRB was studied, including low molecular mass organic acids, alcohols, volatile fatty acid salts and carbohydrates. The results show that sulfate reducing activity decreases in the order of low molecular mass organic acids, volatile fatty acid salts, alcohols and carbohydrates. Considering the removal rate of sulfate and the running cost, formic acid was top priority as the carbon source in the experiments, and the removal rate of sulfate with it reaches 97%.
Key words: sulfate reducing bacteria(SRB); carbon sources; sulfate; removal rate
