Nowadays, anaerobic processes are used for leachate treatment and biogas production that can be used as a source of renewable and eco-friendly energy. However, for optimal performance of the anaerobic system for gas production, an appropriate method must be used to reduce the inhibitors in the leachate. In this study an anaerobic baffled reactor (ABR) was used for investigating impact of OLR on biogas production and changes of alkalinity and pH. In order to decline inhibitors concentration on anaerobic microorganisms, zeolite was considered as a media and changes of biogas production was surveyed in different filling ratios. The highest produced biogas at the filling ratios of 10 %, 20 and 30 % were 0.6, 0.63 and 0.9 L/day, respectively and OLR increasing resulted in increase in produced biogas. The values of alkalinity and pH remained in the optimum range for methanogenic bacteria. In all three filling ratios, concentration of ammonia increased with increasing organic loading rate but it has not adverse effect on biogas production. Despite of high concentration of heavy metals, anaerobic baffled reactor with zeolite provided suitable condition for anaerobic microorganisms and biogas production.

如今，厌氧工艺用于渗滤液处理和沼气生产，可用作可再生和环保能源。然而，为了使厌氧系统产生气体的最佳性能，必须使用适当的方法来减少渗滤液中的抑制剂。在这项研究中，厌氧挡板反应器 (ABR) 用于研究 OLR 对沼气产量以及碱度和 pH 值变化的影响。为了降低厌氧微生物的抑制剂浓度，以沸石为介质，考察不同填充率下沼气产量的变化。在10%、20%和30%的填充率下，最高产沼气量分别为0.6、0.63和0.9 L/d，OLR增加导致产沼气增加。碱度和pH值保持在产甲烷菌的最佳范围内。在所有三种填充率中，氨浓度随着有机负载率的增加而增加，但对沼气产量没有不利影响。尽管重金属含量较高，但沸石厌氧挡板反应器为厌氧微生物和沼气生产提供了适宜的条件。
