氢能因其经济、可持续生产的优势,已逐渐成为不可替代的清洁能源.本实验采用一种新型生物制氢反应器-厌氧挡板反应器,对蔗糖废水40 天的运行情况进行了研究.在对有机废水进行降解的同时制备出有效氢,为实际应用提供了有价值的参考.在低有机负荷条件下成功启动反应器后,在(35±1)℃温度下,pH控制在6.9±0.1 范围内,分阶段增加有机负荷.当COD 为5 599 mg/L 时,反应器的总COD被去除.去除率最高,峰值为58.99％,COD增加到6 136 mg/L时,日产氢量最高,为35.22 L.d.总体而言反应器运行良好,COD 的最佳值为6 136 mg/L,此时系统的产氢效果最好,COD去除率小于峰值.“,”Hydrogen energy has gradually become an irreplaceable clean energy because of its advantages of eco-nomic and sustainable production.In this experiment,a new type of biological hydrogen production reactor,anaerobically baffle reactor,was used to study the operation of sucrose waste water for 40 days.The available hy-drogen was prepared while the organic waste water was degraded,which provided a valuable reference for practi-cal application.After successfully starting the reactor under the condition of low organic load,at the temperature of(35±1)℃,the pH value was controlled in the range of 6.9±0,1,and the organic load was increased in sta-ges.When the COD was 5 599 mg/L,the total COD of the reactor was removed.The removal rate reached the highest,the peak value was 58.99％,and when the COD increased to 6 136 mg/L,the daily hydrogen produc-tion reached the highest value of 35.22 L·d.In general,the operation of the reactor is good,and the optimal COD value is 6 136 mg/L.At this time,the hydrogen-producing effect of the system is the best and the COD removal rate is less than the peak value.
