The study was aimed at treating the complex, combined wastewater generated in Mangolpuri industrial cluster. It was considered as a low strength wastewater with respect to its organic content. Anaerobic treatment of this wastewater was studied using an anaerobic hybrid reactor (AHR) which combined the best features of both the upflow anaerobic sludge blanket (UASB) reactor and anaerobic fluidized bed rector (AFBR). The performance of the reactor under different organic and hydraulic loading rates were studied. The COD removal reached 94% at an organic loading rate (OLR) of 2.08 kg COD m(-3)d(-1) at an hydraulic retention time (HRT) of 6.0 h. The granules developed were characterized in terms of their diameter and terminal settling velocity.
该研究旨在处理芒戈尔普里工业集群产生的复杂混合废水。就其有机含量而言，该废水被视为低强度废水。使用厌氧复合反应器（AHR）对这种废水进行厌氧处理，该反应器结合了上流式厌氧污泥床（UASB）反应器和厌氧流化床反应器（AFBR）的最佳特性。研究了该反应器在不同有机负荷率和水力负荷率下的性能。在水力停留时间（HRT）为6.0小时、有机负荷率（OLR）为2.08 kg COD m(-3)d(-1)时，化学需氧量（COD）去除率达到94%。对形成的颗粒从其直径和终端沉降速度方面进行了表征。
