中文摘要:

利用自制的SBR反应器,在厌-好氧交替运行条件下,采用逐步提高进水负荷的调控方法培养好氧颗粒污泥.针对好氧颗粒污泥的特点,选取影响好氧颗粒污泥成粒的进水COD、进水C/N比、厌氧时长、水力停留时间和曝气量5个因素,采用正交试验方法,探索其对好氧颗粒污泥形成的影响度,找到好氧颗粒污泥形成的最优培养条件.实验证明:在现有实验条件下影响颗粒化率的显著程度依次为:进水COD--沉降时间-厌氧时长-进水C/N比-曝气量-水力停留时间.最优培养条件是进水COD为600～1 300mg/L,沉降时间为10 min,厌氧时长为30 min,进水C/N为10:l,曝气量为0.2 m3/h,水力停留时间为270 min,此条件下培养的好氧颗粒污泥COD去除率和氨氮去除率分别达到96%和83%.

英文摘要:

This paper utilizes self-made SBR reactor to culture aerobic granular sludge(AGS).It uses regulating method of gradually improving influent loads under the condition of anaerobic-aerobic alternative operation.According to the characteristics of AGS,the paper choose five factors:COD,C/N,anaerobic time,hydraulic retention time and aeration,explore the influence degree of the five factors with orthogonal test to seek the optimum cultural condition of AGS.According to the experiment,the significant degree of in...
