【摘要】 内循环厌氧反应器是第三代高效厌氧反应器。Fe2+离子对反应器的颗粒污泥活性具有较明显的影响,投加Fe2+离子质量浓度在2~10mg/L时对颗粒污泥活性都产生明显的促进作用,其最佳投放质量浓度为5mg/L;连续流IC反应器运行结果表明,Fe2+离子可以有效地提高IC反应器的运行效能,采用5mg/L的投加质量浓度,可使反应器的产气量由29.6L/d增加到38L/d,COD去除率从近80%提高到90%左右,提高幅度分别为25%和10%。更多还原

【Abstract】 Internal circulation (IC) anaerobic reactor is the third successful anaerobic reactor. Iron has effect on the activity of granular sludge of the IC anaerobic reactor. It was demonstrated iron was able to enhance the sludge activity at the range of 2～10mg/L. The optimum concentration of iron was 5mg/L. The results of continuous experiment indicate that iron was able to enhance the activity of IC anaerobic reactor at the concentration of 5mg/L. The biogas production increased from 29.6L/d to 38L/d, COD removal efficient increased from 80% to 90%. They were 25% and 10% higher than before added iron.更多还原
