摘　　要：针对IC反应器(内循环厌氧反应器)处理低浓度有机废水过程中进水有机负荷、酸碱性等因素的变化,探讨了IC反应器处理低浓度有机废水过程中pH的变化与VFA(挥发性脂肪酸)、碱度等因素的关系.结果表明:根据Pearson简单相关系数法和灰色关联度分析,可以得到COD(化学需氧量)去除率与进水pH值之间的相关系数为0.044,相关性较弱,灰色关联度系数为0.507 7;COD去除率与进水VFA值之间的相关系数为-0.168,具有负相关性,灰色关联度系数为0.601 9;COD去除率与进水碳酸氢盐碱度之间的相关系数为0.259,具有正相关性,灰色关联度系数为0.613 2.For variations of influent organic load,pH and other factors in the process of IC reactor treating low-concentration organic wastewater,the relationship among the change of pH and VFA,alkalinity,and other factors in this process is discussed.By simple correlation coefficients of Pearson and the grey absolute correlation analysis,correlation coefficient between the removal of COD and pH of influent of 0.044 is obtained,the correlation is weak,and the grey correlation coefficient is 0.5077.But negative correlation coefficient between the removal of COD and VFA of influent is 0.168,and the grey correlation coefficient is 0.6019.In addition,positive correlation coefficient between the removal of COD and alkalinity of influent is 0.259,and the grey correlation coefficient is 0.6132.
