对爱荷华州某屠宰场废水的现场中试静态颗粒床反应器（SGBR）系统进行了评价。研究评价了SGBR反应器在0.3-1.4 m3/m2/天的表面负荷率下对具有高颗粒COD浓度（7.9 ± 4.3 g COD/L）的屠宰废水的适用性。在HRT为48、36、30、24和20 h时，由于SGBR系统的可处理性一致，因此获得了较高的有机物去除率（TSS和VSS去除率均在95%以上）。出水TSS、VSS、COD、可溶性COD和BOD 5的平均浓度分别为84、71、301、197和87 mg/L。每7-14天进行一次有效的反冲洗程序，以浪费系统中积累的一部分固体。这一措施限制了水头损失的增加，保持了系统的稳定性。COD去除率大于95%，达到有机负荷率范围从0.77至12.76公斤/立方米/天。
An on-site pilot-scale static granular bed reactor (SGBR) system was evaluated for treating wastewater from a slaughterhouse in Iowa. The study evaluated SGBR reactor suitability for slaughterhose wastewater having high particulate COD concentration (7.9 ± 4.3 g COD/L) at 0.3–1.4 m3/m2/day of the surface loading rates. High organic removal efficiency (over 95% of TSS and VSS removal) was obtained due to the consistent treatability of SGBR system during operation at HRTs of 48, 36, 30, 24, and 20 h. The average effluent TSS, VSS, COD, soluble COD, and BOD5concentrations were 84, 71, 301,197, and 87 mg/L, respectively. An effective backwash procedure was performed once every 7–14 days to waste a portion of the accumulated solids in the system. This procedure limited the increase in hydraulic head loss and maintained the system stability. COD removal efficiencies greater than 95% were achieved at organic loading rates ranging from 0.77 to 12.76 kg/m3/day.
