The present study investigates the performance of a pilot-scale Sequencing Batch Reactor (SBR) process for the treatment of wastewater quality parameters, including turbidity, total suspended solids (TSS), total solids (TS), nitrogen (ammonia (NH-N), nitrite (NO), and nitrate (NO), phosphate (PO), the chemical oxygen demand (COD), and the 5-day biological oxygen demand (BOD), from municipal wastewater. Two scenarios, namely, pre-anoxic denitrification and post-anoxic denitrification, were investigated to examine the performance of a pilot-scale SBR on the wastewater quality parameters, particularly the nitrogen removal. The correlation statistic was applied to explain the effects of operational parameters on the performance of the SBR system. The results revealed that the post-anoxic denitrification scenario was more efficient for higher qualify effluent than the first scenario. The effluent concentrations of the targeted wastewater quality parameters obtained for the proposed SBR system were below those of the local standards, while its performance was better than that of the North Sewage Treatment Plant, Dharan, Eastern province, Kingdom of Saudi Arabia (KSA), in terms of the BOD, COD, TN, and PO treatment efficiencies. These results indicated the suitability of SBR technology for wastewater treatment in remote areas in the KSA, with a high potential of reusability for sustainable wastewater management.
本研究考察了中试规模序批式反应器（SBR）处理废水水质参数的性能，包括浊度、总悬浮固体（TSS）、总固体（TS）、氮（氨氮（NH-N）、亚硝酸盐（NO）和硝酸盐（NO）、磷（PO）、化学需氧量（COD）和五日生物需氧量（BOD），来自城市废水。考察了预缺氧反硝化和缺氧后反硝化两种情况，以检查中试规模 SBR 对废水水质参数的性能，特别是对氮去除的影响。应用相关统计分析来解释操作参数对 SBR 系统性能的影响。结果表明，与第一个方案相比，缺氧后反硝化方案更有利于获得更高质量的出水。所提出的 SBR 系统处理目标废水水质参数的出水浓度低于当地标准，而其 BOD、COD、TN 和 PO 处理效率均优于沙特阿拉伯王国（KSA）东部省份达兰的北污水处理厂。这些结果表明 SBR 技术适用于 KSA 偏远地区的废水处理，具有很高的可持续废水管理再利用潜力。
