| 摘 要： | 研究1·2m3厌氧反应器(UASB),在自然温度(水温32~5℃)下,处理CODCr浓度为200mg/L左右的低浓度生活污水。实验采用颗粒污泥接种二次启动法。水处理系统在水温32~5℃范围内运行6个月的时间,UASB反应器在上升流速为1·4~1·7m/h,水力停留时间(HRT)为3·0~2·5h,CODCr有机污泥负荷(SLR)为0·06~0·13kg/(kg·d)时,去除效率比较稳定,CODCr去除率达40%~80%。 |

| Abstract: | Influence,parameters and model of a 1.2 m~3 up-flow anaerobic sludge blanket(UASB) reactor was studied,which was operated at low operating parameters of 200 mg COD_ Cr /L.The secondary start-up of granular sludge inoculation was used for the test.The reactor was operated under SLR of 0.06～0.13 kg/(kg·d),liquid upflow velocity of 1.4～1.7 m/h and hydraulic retention time(HRT) of 3.0～2.5 h at temperature of 32～ 5 ℃ ,for six months.The COD_ Cr removal efficiency is 40%～80%. |
