【摘要】 本文对折流挡板厌氧反应器处理生活污水进行了研究。反应器沿流向分为三格,实验温度为25℃,水力停留时间12小时,pH在7~7.6。实验结果表明:COD的去除率可维持在70%左右,产气主要含有甲烷、二氧化碳和氢气,每格最大产甲烷活性依次为211 mLCH4.gVSS-1d-1,314 mLCH4.gVSS-1d-1,319 mLCH4.gVSS-1d-1;出水产物为乙酸和丙酸;每格优势菌种依次为杆菌、球菌、甲烷丝状菌和甲烷八叠球菌。填料挂膜量(湿重)沿着流向逐渐降低,平均为4.27 g.cm-3。更多还原

【Abstract】 In this study the anaerobic baffled reactor（ABR） was used to treat municipal wastewater.ABR was separated to three sequential units,and worked at the condition of pH 7.0～7.6,temperature 25 ℃,HRT 12 h,and glucose as substrate.The results indicated: COD removal efficiency could remain at 70%,the product gas was mainly composed of methane,carbon dioxide and hydrogen,the maximal methane producing activity sequentially were 211 mLCH₄·gVSS^-1d^-1,314 mLCH₄·gVSS^-1d^-1,319 mLCH₄·gVSS^-1d^-1;The main components of effluent were acetic acid and propanoic acid; The dominant microorganisms sequentially were Bacillus,Coccus,Methanothrix and Methanosaet.The mass of attached bio-membrane decreased along the flow,and the average mass of attached bio-membrane in terms of wet weight was 4.27 g·cm^-3.更多还原
