Fe3+%污泥%酸性发酵%丙酸比率
Fe3+%汙泥%痠性髮酵%丙痠比率
Fe3+%오니%산성발효%병산비솔
Fe3+%sludge%acidogenic fermentation%propionic acid ratio
采用半连续运行的序批式反应器进行试验，研究了发酵液中Fe3＋对污泥微氧酸性发酵产物中丙酸比率的影响；分析了在不同Fe3＋质量浓度下，发酵液中COD、糖、蛋白、氨氮、磷酸盐和细菌总数，产酸菌的变化规律。实验表明，投加Fe3＋有利于提高发酵产物中丙酸产（比）率，当Fe3＋投加质量浓度为50 mg/L时，反应器中产酸菌数量最多，丙酸占总酸比例达到峰值。
採用半連續運行的序批式反應器進行試驗，研究瞭髮酵液中Fe3＋對汙泥微氧痠性髮酵產物中丙痠比率的影響；分析瞭在不同Fe3＋質量濃度下，髮酵液中COD、糖、蛋白、氨氮、燐痠鹽和細菌總數，產痠菌的變化規律。實驗錶明，投加Fe3＋有利于提高髮酵產物中丙痠產（比）率，噹Fe3＋投加質量濃度為50 mg/L時，反應器中產痠菌數量最多，丙痠佔總痠比例達到峰值。

Effects of Fe3+ concentration on the propionic acid ratio in acidogenic fermentation product of sludge are investi-gated in sequencing batch reactor with semi continuous operation mode .The changing rules of COD ,soluble sugar ,protein , NH4+ -N ,phosphorus ,total number of bacteria and acid bacteria in fermentation liquor are analyzed .Experiments show that adding Fe3+ can help to improve the propionic rate of the fermented product ,when the concentration of Fe3+ dosing is 50 mg/L ,the acid bacteria in the reactor reaches the maximum and the propionic acid ratio can also reach the peak .
