Aerobic granular sludge (AGS) was successfully cultivated at 27±1 °C and pH 7.0±1 during the treatment of rubber wastewater using a sequential batch reactor system mode with complete cycle time of 3 h. Results showed aerobic granular sludge had an excellent settling ability and exhibited exceptional performance in the organics and nutrients removal from rubber wastewater. Regular, dense and fast settling granule (average diameter, 1.5 mm; settling velocity, 33 m h(-1); and sludge volume index, 22.3 mL g(-1)) were developed in a single reactor. In addition, 96.5% COD removal efficiency was observed in the system at the end of the granulation period, while its ammonia and total nitrogen removal efficiencies were up to 94.7% and 89.4%, respectively. The study demonstrated the capabilities of AGS development in a single, high and slender column type-bioreactor for the treatment of rubber wastewater.
在 27±1°C 和 pH7.0±1 的条件下,采用序批式反应器系统模式处理橡胶废水,成功培养出好氧颗粒污泥(AGS)。整个周期为 3 小时。结果表明,好氧颗粒污泥具有优异的沉降性能,在去除橡胶废水中的有机物和营养物质方面表现出色。在单个反应器中形成了规则、致密和快速沉降的颗粒(平均直径为 1.5 毫米;沉降速度为 33 米/小时;污泥体积指数为 22.3 毫升/克)。此外,在颗粒形成期结束时,系统中观察到 96.5%的 COD 去除效率,而其氨氮和总氮去除效率分别高达 94.7%和 89.4%。该研究表明,AGS 可在单个、高而细长的柱状生物反应器中开发,用于处理橡胶废水。
