摘　　要：在室温条件下,以水葫芦汁液为废水来源,对自行设计的膨胀颗粒污泥床(EGSB)厌氧反应器进行原废水循环启动实验。结果表明:在启动运行65d后,进水有机负荷可以达到7kg/(m^3·d)左右,COD去除率达到90%以上,容积产气率达到1.35m^3/(m^3·d),甲烷体积分数达到61%,颗粒污泥粒径达到2~4mm。因此,EGSB厌氧反应器的原废水循环启动方式是可行的,对水葫芦汁液的降解是高效的,为EGSB厌氧反应器的工程应用提供一种新的启动方式,也为水葫芦汁液的能源化利用提供了一套高效、节能的厌氧发酵装置。In order to study the experiment of start-up in circulation feed water of EGSB anaerobic reactor,the anaerobic digester experiment was performed at room temperature using the juice of water hyacinth as feedstock. The results showed that after running 65 d,the influent organic loading rate could reach 7 kg/（m^3·d）. The removal effi- ciency of COD was more than 90 %. The volume biogas yield were achieved 1.35 m^3/（m^3·d） with 61 % volume fraction of methane. The particle size of granular sludge reached 2-4 mm. Therefore,start-up in circulation feed water of EGSB anaerobic reactor was practicable and its removal efficiency on juice of water hyacinth was high efficient. A new start-up method for application of EGSB anaerobic reactor and a raising efficiency and saving energy anaerobic reactor for the anaerobic digestion of juice of water hyacinth could be provided.
