| 中文摘要 |
| 以4格室单侧进水厌氧折流板反应器（ABR）为对照，研究了分区进水对ABR运行效果的影响.结果表明，在室温条件下，HRT=4 h时，单侧进水ABR对溶解性COD去除率为30%，而分区进水ABR对COD的去除率平均为35%，最高可达45%，COD去除率平均提高5%以上.分区进水ABR各室内生物种群主要以兼性水解酸化菌为主，同时亦存在产甲烷菌.分区进水避免了反应器第1格室内有机负荷过高，挥发性脂肪酸（VFA）过度积累的弊端，改善了反应器后部格室有机基质不足的现象，增强了反应器内微生物的活性，提高了对污染物去除的能力. |
| 英文摘要 |
| The experimentation studied running efficiency of divisional influent mode to anaerobic baffled reactor (ABR) compared with single influent anaerobic baffled reactor that had four compartments. The results showed that the average soluble COD removal rate of single influent was 30%,but divisional influent anaerobic baffled reactor was 35%, and the highest value might reach to 45%, the removal rate of COD was improved over 5% than single influent anaerobic baffled reactor. The main biological processes were micro-aerobic hydrolysis and acidification,at the same time the methane-producing bacteria existed too. The means of divisional influent could avoid high organic loading in the first compartment that led the volatile fatty acids (VFA) to accumulate overly and might improve the fact of lacking organic substance at the back compartment and let reactor to have high microorganism activity and improve ability of reducing contamination. |
