摘　　要：以发酵法生物制氢反应器排放的废液为培养基,考察了复合型高效产絮菌F2-F6制取生物絮凝剂(BF)的最佳发酵条件。试验结果表明,在初始pH值为7.0、发酵周期为21 h、摇床转速为140 r/m in、发酵温度为30℃、制氢废液不灭菌的条件下,制取的BF对高岭土的最大絮凝率>93.0%。同时,考察了制取的BF对生活污水、墨汁废水和高浓度中药废水的净化效果,结果表明对浊度、色度和有机物的去除率分别达到98.7%、96.9%和62.6%。The compound bio-flocculants-producing bacteria, named F2 -F6, was adopted to investigate the optimum fermentation conditions using the effluent from bio-hydrogen-producing reactor as culture substrate. The experimental results indicate that the optimum fermentation conditions are as follows： initial pH of 7.0, fermentation time of 21 h, rotation speed of 140 r/min, temperature of 30℃ and no sterilization of the culture. Under these conditions, the maximum flocculation rate of the bio-flocculants （BF） produced is over 93.0%. It is also found that the bio-flocculants have high capacity of turbidity-removal, color-removal and organic-removal when the BF are employed to treat domestic wastewater, black ink wastewater and Chinese medicine wastewater respectively.
