An innovative biomass carrier (Biobob®) was tested for municipal wastewater treatment in an activated sludge system to evaluate the pollutant removal performance and the sludge generation for different carrier volumes. The experiment was carried out in a pilot-scale cyclic activated sludge system (CASS®) built with three cylindrical tanks in a series: an anoxic selector (2.1 m(3)), an aerobic selector (2.5 m(3)) and the main aerobic reactor (25.1 m(3)). The results showed that by adding the Biobob® carrier decreased the MLVSS concentration, which consequently reduced the waste sludge production of the system. Having 7% and 18% (v/v) support material in the aerobic reactor, the observed biomass yield decreased 18% and 36%, respectively, relative to the reactor operated with suspended biomass. The addition of media did not affect the system's performance for COD and TSS removal. However, TKN and TN removal were improved by 24% and 14%, respectively, using 18% (v/v) carrier.
一种创新的生物质载体（Biobob®）在活性污泥系统中用于处理城市废水，以评估不同载体体积的污染物去除性能和污泥生成。该实验在一个带有三个圆柱形罐体的中试规模循环活性污泥系统（CASS®）中进行，罐体依次为缺氧选择器（2.1 m3）、好氧选择器（2.5 m3）和主好氧反应器（25.1 m3）。结果表明，添加 Biobob®载体降低了 MLVSS 浓度，从而减少了系统的剩余污泥产量。在好氧反应器中添加 7%和 18%（v/v）的支撑材料，相对于悬浮生物量运行的反应器，观察到生物量产率分别降低了 18%和 36%。添加介质不会影响系统对 COD 和 TSS 的去除性能。然而，使用 18%（v/v）载体可分别将 TKN 和 TN 的去除率提高 24%和 14%。
