摘要

对ABR系统进行改良，建立新型的“活性污泥-生物膜”杂合厌氧折流板生物制氢反应器（SMHABR），研究其乙醇型发酵的形成及其产氢及COD处理能力。反应器分为5个格室，有效容积43.2 L，实验共进行180 d。系统以红糖废水为原料，在HRT为12 h，温度为（35±1）℃，通过分阶段提高进水COD的方式，可使ABR系统在35 d内培育驯化形成乙醇型发酵菌群体系。进水COD在约3500 mg·L-1时产氢量最大，总产氢量可达到44.75 L·d-1。进水COD浓度达到约7100 mg·L-1时COD去除率最大，平均总去除率可达到49.33%。COD去除率最大值并未与产氢量最大值同时出现，说明产氢最适进水浓度与COD去除最适进水浓度并非相同。

Abstract

The new sluge-micobial film hybrid anaerobic baffled reactor (SMHABR) was obtained by the improvement of the original ABR with five compartments and effective volume of 43.2 L. The experimentation studied on the formation of ethanol type fermentation

the hydrogen production capacity and the COD removal capacity. The result of 180 days experiment showed that using brown sugar wastewater as raw material with hydraulic retention time of 12 h

temperature of 35℃±1℃

the system of ethanol type fermentation bacteria could be formatted in 35 days through increasing the influent COD in a phased operation mode. When the influent COD was about 3500 mg·L-1

the maximum hydrogen production was achieved with the total hydrogen production of 44.75 L·d-1. The hydrogen production of the second compartment was larger than that of the other compartments. When the influent COD was about 7100 mg·L-1

the maximum COD removal capacity was achieved with the average total COD removal rate of 49.33%. The maximum hydrogen production and the maximum COD removal rate did not appear at the same time. When the influent COD concentration was too high

the organic acid accumulation in the reactor was too much

resulting in the reactor pH down to 3. Low pH affected the hydrogen production efficiency of the system. Although ethanol fermentation was formed in the system

the hydrogen production capacity was low.
