【摘要】 本文从厌氧发酵过程的机理出发,对PH值的影响因素进行了分析。根据电离平衡理论,导出了不同条件下厌氧发酵过程PH值的理论计算公式。并根据Cobb的实验结果对计算公式进行了验证,结果表明公式较好地描述厌氧发酸过程影响PH值变化主要因素,并能对PH值进行预测计算。对厌氧反应器实际运行有一定指导意义。更多还原

【Abstract】 s: The influence factors of PH in anaerobic fermentation were discussed in this paper. According to the ionic equilibrium theory, the PH calculating models were proposed under different anaerobic digestion conditions. The models were verified with Cobb’s experimental The results show that the PH calculating models can describe main influence factors of PH in anaerobic fermentation well.更多还原
