With inoculum sludge from a conventional activated sludge wastewater treatment plant, three sequencing batch reactors (SBRs) fed with synthetic wastewater were operated at different high temperatures (30, 40 and 50±1°C) to study the formation of aerobic granular sludge (AGS) for simultaneous organics and nutrients removal with a complete cycle time of 3h. The AGS were successfully cultivated with influent loading rate of 1.6CODg(Ld)(-1). The COD/N ratio of the influent wastewater was 8. The results revealed that granules developed at 50°C have the highest average diameter, (3.36mm) with 98.17%, 94.45% and 72.46% removal efficiency observed in the system for COD, ammonia and phosphate, respectively. This study also demonstrated the capabilities of AGS formation at high temperatures which is suitable to be applied for hot climate conditions.
采用传统活性污泥法污水处理厂的接种污泥，在不同高温（30、40 和 50±1°C）下运行三个序批式间歇反应器（SBR），以合成废水为进水，研究了好氧颗粒污泥（AGS）的形成，用于同时去除有机物和营养物质，整个周期为 3 小时。在进水负荷率为 1.6CODg(Ld)(-1)的条件下成功培养出 AGS。进水废水中的 COD/N 比为 8。结果表明，在 50°C 下培养的颗粒具有最高的平均直径（3.36mm），在 COD、氨和磷酸盐方面，系统的去除效率分别达到 98.17%、94.45%和 72.46%。本研究还证明了高温下 AGS 形成的能力，这适合应用于炎热气候条件。
