Abstract

Using conventional activated sludge of breweries as the inoculation sludge, stable aerobic granular sludge was fostered successfully in sequencing batch reactor, and applied to municipal sewage disposal. At room temperature, chemical oxygen demand and NH4+-N removal efficiency of aerobic granular sludge was surveyed. Results indicated that chemical oxygen demand and NH4+-N average removal efficiencies reached 80% and 82% respectively. When concentration of aerobic granular sludge changed in the range of 2700 to 3600 mg/L, aerobic granular sludge had better settling performance, and chemical oxygen demand and NH4+-N removal efficiencies were higher than the conventional activated sludge. When sludge volumetric index of granular sludge changed from 30 to 50mL/g, average particle size of granular sludge was stable in 0.5 to 1.20 mm. Simultaneous, nitrification and denitrification of aerobic granular sludge was also discussed in this research.
好氧颗粒污泥处理城市污水的研究
以啤酒厂常规活性污泥为接种污泥,在序批式反应器中成功培养出稳定的好氧颗粒污泥,并应用于城市污水处理。在室温条件下,考察了好氧颗粒污泥的化学需氧量和NH4+-N去除率。结果表明,化学需氧量和NH4+-N的平均去除率分别达到80%和82%。当好氧颗粒污泥浓度在2700 ~ 3600 mg/L范围内变化时,好氧颗粒污泥具有较好的沉降性能,化学需氧量和NH4+-N去除率均高于常规活性污泥。当颗粒污泥污泥体积指数在30 ~ 50mL/g范围内变化时,颗粒污泥的平均粒径稳定在0.5 ~ 1.20 mm。同时对好氧颗粒污泥的硝化和反硝化进行了研究。
