【摘要】 通过在SBR中分别接种85%的絮状活性污泥和15%的丝状菌,采用以葡萄糖为碳源配制的人工模拟进水,研究丝状菌对好氧颗粒污泥形成的影响。结果在15 d内培养出理化性能良好的好氧颗粒污泥,表明丝状菌能够加快好氧颗粒污泥的形成。反应器运行期间,COD、NH4+-N、总氮和总磷的平均去除率分别为80.0%、86.9%、70.0%和42.5%,且出水水质稳定,表明好氧颗粒污泥具有良好的除污效果。更多还原

【Abstract】 The effects of filamentous bacteria on the formation of aerobic granule sludge were investigated by inoculating 85% activated sludge and 15% filamentous bacteria,feeding synthetic municipal wastewater with glucose as carbon source in SBR.The aerobic granule sludge with good physicochemical properties were formed within 15 d.The results showed that filamentours bacteria could speed up the formation of aerobic granule sludge.During the operation of SBR,the average removal rate of COD,NH⁺₄-N,TN and TP were 80.0%,86.9%,70.0% and 42.5% respectively,and yielded more stable quality of effluent water,indicating that the aerobic granule sludge had a better contaminant removal effect.更多还原
