摘    要:广东某城市污水处理厂采用UASB-好氧工艺处理低浓度城市污水,对UASB的实际处理效能进行了考察。结果表明,在试验的进水水质条件下,当UASB的水力停留时间为6h时,系统对COD和BOD5的平均去除率分别为50%和60%,对TP的去除率为15%~38%。当HRT由5.67h延长至10h时,出水VFA浓度会随之降低,而pH值则始终稳定在6.5~7.5,系统对COD和BOD5的去除率分别增加9%和19%,对溶解性COD和BOD5的去除率分别增加25%和24%。

关 键 词:升流式厌氧污泥床  低浓度城市污水  水力停留时间

Abstract:The actual operation performance of upflow anaerobic sludge blanket(UASB) reactor coupled with an aerobic process for treating low-strength municipal sewage was investigated in a Guangdong municipal sewage treatment plant.The results indicate that under HRT of 6 h in UASB reactor,the average removal rates of COD,BOD5,and TP in the system are 50%,60% and 15% to 38%,respectively.When the HRT extends from 5.67 to 10 h,the effluent VFA concentration declines,pH value steadies at 6.5 to 7.5,the average removal rates of COD,BOD5,dissolved COD and BOD5 are increased by 9%,19%,25% and 24% respectively.
Keywords:UASB  low-strength municipal sewage  HRT
