| 摘 要：以檸檬酸廠(chǎng)IC反應器的顆粒污泥為接種污泥啟動(dòng)UASB反應器處理垃圾滲濾液，探討了啟動(dòng)后不同階段容積負荷、水力停留時(shí)間、pH等主要運行參數對COD去除率的影響。低容積負荷接種污泥逐步適應廢水水質(zhì)，隨著(zhù)容積負荷提高，COD去除率也逐步提高，容積負荷為8~9 kgCOD/（m3·d），水力停留時(shí)間為18 h，pH控制在6.8~7.2，產(chǎn)酸菌和產(chǎn)甲烷菌的活性高，COD去除率大于70%。 |
| 關(guān)鍵詞：UASB反應器；垃圾滲濾液；COD去除率 |

| Abstract：The granular sludge from IC reactor of citric acid plant was used as inoculated sludge to start UASB reactor. The influences of main operation parameters such as volumetric load, hydraulic retention time and pH on COD removal rate were discussed in different stages of start-up process. The low volume load inoculated sludge gradually adapted to the wastewater quality, and the COD removal rate gradually increased with the increase of the volume load, and the optimal volume load was 8~9 kgCOD/(m3·d). High or low hydraulic retention time was not conducive to COD removal, and the hydraulic retention time was 18 h.When the pH value was controlled between 6.8 and 7.2, the activity of acid-producing bacteria and methanogens was very high, and the COD removal rate is basically above 70%. |
| Key words：UASB reactor; landfill leachate; COD removal rate |
