Abstract

Abstract The purpose of this work is to evaluate the performance of the anaerobic baffled reactor (ABR) for on-site primary treatment of domestic wastewater in rural areas of Iraq. The performance of the three-chamber ABR has been investigated at four different hydraulic retention times (HRTs) ranging from 6 to 36 h. The results showed that the chemical oxygen demand (COD) removal efficiency is enhanced with increasing HRT, where it was recorded at 75, 71, 63, and 56% removals rate of COD at HRTs of 36, 24, 12, and 6 h, respectively. The mean steady-state removals of total suspended solids are 91, 78, 72, and 67% at HRTs of 36, 24, 12, and 6 h, respectively. Also, it was shown that there was low-nutrients removal within the ABR. Consequently, the effluent ABR wastewater needs to be post-treated before being discharged to the receiving water bodies. In general, it is concluded that the ABR could introduce a solution for on-site primary treatment of domestic wastewater in rural communities in Iraq.

厌氧折流板反应器在伊拉克农村生活污水一级处理中的性能

摘要本工作的目的是评估厌氧折流板反应器（ABR）在伊拉克农村地区生活污水现场一级处理中的性能。研究了三腔ABR在6～36个不同水力停留时间（HRT）下的性能 h.结果表明，化学需氧量（COD）的去除效率随着HRT的增加而提高，在HRT为36、24、12和6时，COD的去除率分别为75%、71%、63%和56% h、分别。在HRTs为36、24、12和6时，总悬浮固体的平均稳态清除率分别为91、78、72和67% h、分别。此外，还表明ABR中的营养物质去除率较低。因此，ABR废水在排放到接收水体之前需要进行后处理。总之，ABR可以为伊拉克农村社区的生活污水现场一级处理提供一种解决方案。
