| 摘 要： | 采用低浓度城市生活污水,以好氧絮状活性污泥为接种污泥,在3个不同运行条件的序批式反应器(SBR)中培养好氧颗粒污泥,并考察了其降解特性.结果表明,通过对剪切力、沉降时间等运行参数的调控,3个反应器(R1～R3)分别在第14、16和14天出现了细小颗粒,成熟后的颗粒污泥粒径可达到1.0 mm,其中R1、R2中颗粒的粒径无明显差别,而R3中颗粒的粒径较R1,R2中的略大;成熟的颗粒污泥周围出现大量原生动物,各反应器内污泥的SV1值保持在29-40 mL/g内,显示出良好的沉降性能.成熟的颗粒污泥对有机碳源具有较强的吸附与降解性能,并且具有同步硝化反稍化能力.各反应器出水COD浓度稳定在30 mg/L左右,NH4+-N浓度＜1.0mg/L,对污染物的去除效果良好. |

| Abstract: | With aerobic flocculent activated sludge as seed sludge,aerobic granular sludge was cultivated using a low-strength municipal wastewater in three sequencing batch reactors(SBR) under different operating conditions.The degradation characteristics of the granular sludge were investigated.The results indicate that through controlling shear force,settling time and other parameters,small granules are observed in the 14th,16th and 14th d in the three reactors(R1 to R3) respectively.The average size of the mature ... |
