【摘要】 为探讨好氧污泥颗粒化过程及其性能,在气升式间歇反应器中培养好氧颗粒污泥,并对模拟生活污水的处理效果进行连续监测。实验表明,成熟好氧颗粒污泥性能良好,沉降速度最高为33.85 m/h,SVI降到了32.24 L/g,颗粒强度达到82.63%,颗粒污泥的耗氧速率(OURW)为1.20 mg/(g.min)-1。这些理化指标均优于普通的活性污泥,所形成的好氧污泥颗粒长期稳定存在。好氧颗粒污泥对污染物的去除能力较强,COD去除率高达96.10%,氨氮和总磷的去除率也高达80%,且出水水质稳定。更多还原

【Abstract】 The paper is an attempt to cultivate the aerobic granular sludge was cultivated in Sequencing Batch Airlift Reactor(SBAR),study the formation of aerobic granular sludge and the granulation process,and continuously observe the treating effects of municipal wastewater.The results show that well-cultivated aerobic granular sludge offers the settling velocity of 33.85 m/h,SVI of 32.24 L/g and the strength up to 82.63% and specific oxygen-utilizing rate of sludge(OURW) of about 1.20 mg/(g·min)-1.The granular activated sludge exhibits better properties than conventional activated sludge and so can last for a longer period.The granular activated sludge shows the COD removal rate up to 96.10% and the removal rates of NH3-N and TP up to 80% respectively,and yields more stable quality of effluent water.更多还原
