厌氧挡板反应器(ABR)是使用厌氧发酵工艺处理垃圾渗滤液的有效解决方案,这有助于降低运行成本和污泥量。为了更好地理解生物学,化学,和所涉及的物理过程,尤其是当ABR与有氧成分结合时,该研究旨在研究包括用于处理垃圾渗滤液的厌氧-好氧混合挡板反应器(AABR)的性能。这项研究利用了两个玻璃反应器。第一个反应堆,指定为AABR-AF,由六个并排排列的独立矩形玻璃室组成。第三和第六室设计用于有氧处理和AF,分别。第二反应器用作对照反应器并且不包括任何需氧室。浊度的最高去除效率(REs),COD,CODBOD,TP,TKN,硝酸盐,TOC,AABR-AF和ABR-AF中的TSS分别为(65.4%和56.3%),(98.3%和94.1%),(98.1%和93.2%),(86.4%和65%),(89.2%和76.7%),(81.2%和64.4%),(88.2%和79.4%),和(72.4%和68.5%),分别。这些最佳RE在48小时的HRT和10kg/m3的OLR下实现。D.此外,重金属(HMs)中最高和最低的RE分别为AABR-AF中锰的89.57%和ABR-AF中镍的6.59%,在10kg/m3的OLR中。D,分别。发现使用AABR-AF和ABR-AF有效去除垃圾渗滤液中的有机物(OMs)受到HRT和OLR的强烈影响。AABR-AF配置,在反应器中有一个单一的好氧室,与ABR-AF配置相比,在去除OMs方面表现出更高的效率。
The Anaerobic Baffled Reactor (ABR) is an effective solution for landfill leachate treatment using an anaerobic fermentation process, which helps to reduce operating costs and sludge volume. To better understand the biological, chemical, and physical processes involved, especially when combining the ABR with an aerobic component, the study aimed to investigate the performance of an Anaerobic-Aerobic Hybrid Baffled Reactor (AABR) that includes an Anaerobic Filter (AF) for treating landfill leachate. This research utilized two glass reactors. The first reactor, designated as AABR-AF, consisted of six independent rectangular glass chambers arranged side by side. The third and sixth chamber designed for aerobic treatment and AF, respectively. The second reactor was used as a control reactor and did not include any aerobic chamber. The highest Removal Efficiencies (REs) for turbidity, COD, BOD, TP, TKN, nitrate, TOC, and TSS in the AABR-AF and ABR-AF were found to be (65.4% and 56.3%), (98.3% and 94.1%), (98.1% and 93.2%), (86.4% and 65%), (89.2% and 76.7%), (81.2% and 64.4%), (88.2% and 79.4%), and (72.4% and 68.5%), respectively. These optimal REs were achieved at an HRT of 48 h and an OLR of 10 kg/m3.d. Also, the highest and the lowest REs in Heavy Metals (HMs) were 89.57% for manganese in AABR-AF and 6.59% for nickel in ABR-AF, in an OLR of 10 kg/m3.d, respectively. The effective removal of Organic Matters (OMs) from landfill leachate using the AABR-AF and ABR-AF was found to be strongly influenced by HRT and OLR. The AABR-AF configuration, featuring a single aerobic chamber in the reactor, exhibited a higher efficiency in removing OMs compared to the ABR-AF configuration.
