pH值对纯菌种Ethanologenbacterium sp.nov R3产氢的影响
Effects of pH value on fermentative biohydrogen production with Ethanologenbacterium sp. nov R3 in continous stirred tank reactor
摘要
Abstract
In this paper, Ethanologenbacterium sp. nov R3 was used as research microbe which was inoculated from continuous stirred tank reactor (CSTR). The temperature and HRT of CSTR were controlled at ( 35 ± 1 ) ℃ and 8 h respectively. The effects of influent pH value on fermentative biohydrogen production with R3 were showed in this paper. When influent pH value was 5.5, the capacity of R3 to produce hydrogen was best. In this influent pH value, biogas yield and hydrogen content respectively achieved 6.85 ～ 8.86 L/d and 59.44％ ～65. 13％. COD removal and effluent pH value were mainly stable at 26％ and 4.38.The average concentration of ethanol and acetic acid in VFAs were respectively 706 mg/L and 446 mg/L. R3 maintained ethanol - type fermentation characteristics all along.关键词
