采用连续流槽式搅拌反应系统(ACSTR)作为反应装置,以制糖废水为底物,污水处理厂剩余污泥为反应的启动污泥,着重研究底物质量浓度和HRT对系统同步产氢产乙醇性能的影响.结果表明,在不同的底物质量浓度和HRT条件下,乙醇产量和氢气产量有着相同的变化趋势.当底物质量浓度和HRT分别为6 g COD/L和6 h时,乙醇和氢气产量分别为1.62/7.25 mmol/(L·h)and 2.97/8.73 mmol/(L·h).线性分析发现乙醇产量和氢气产量之间有很好的相关性,线性方程分别为y=0.156 6x+0.4487(r2=0.8778)和y=0.148 8x+1.671 4(r2=0.9838).
The continuous flow tank stirred reaction system (ACSTR) was used as the reaction device. The waste water from the wastewater treatment plant was taken as the reaction start-up sludge. The concentration of the substrate and the HRT were used to study the simultaneous hydrogen production Ethanol.The results showed that under the different substrate concentration and HRT conditions, the ethanol yield and hydrogen production had the same trend.When the substrate concentration and HRT were 6 g COD / L and 6 h respectively, The yields of ethanol and hydrogen were 1.62 / 7.25 mmol / (L · h) and 2.97 / 8.73 mmol / (L · h), respectively. Linear analysis showed a good correlation between ethanol production and hydrogen production. The linear equations were y = 0.156 6x + 0.4487 (r2 = 0.8778) and y = 0.148 8x + 1.671 4 (r2 = 0.9838).
