利用厌氧污泥对啤酒废水进行了产氢实验。采用Box-Behnken法的三因素三水平实验设计，对该菌产氢条件进行优化。采用响应面分析法（RSM）结合期望函数法，研究了温度、pH和啤酒废水浓度3个主要影响因素对H2产率和最大产氢速率（Rmax）的影响。在温度35.9°C、pH 5.95和BWC 6.05g/l的条件下，H2产率和Rmax同时达到理想值，用期望函数法得到的最大综合期望值为0.894。相应地，H2产率和Rmax分别为149.6ml H2/g COD和53.6ml/h。验证试验表明，最佳H2产率和Rmax的实测值与预测值吻合较好，表明响应面期望函数法是同时获得最大H2产率和Rmax的有效方法。
Brewery wastewater was converted H2by anaerobic sludge in batch experiments. A three-factor three-level experimental design of Box-Behnken method was adopted to find the optimum H2production conditions. The effects of three major influence factors, temperature, pH and brewery wastewater concentration (BWC), on H2yield and H2maximum production rate (Rmax) were evaluated by applying response surface methodology (RSM) integrating a desirability function approach. Desirable H2yield and Rmaxsimultaneously were achieved under temperature 35.9°C, pH 5.95 and BWC 6.05g/l by a desirability function approach which produced the maximum overall desirability 0.894. Correspondingly, the H2yield and Rmaxwere 149.6ml H2/g COD and 53.6ml/h, respectively. The verification test confirms that the optimum H2yield and Rmaxmeasured were in good agreement with the predicted values, suggesting that the desirability function approach with RSM was a useful technique to get the maximum H2yield and Rmaxsimultaneously.
