摘　　要：在中温条件下投加颗粒活性炭可加快ＵＡＳＢ反应器颗粒化进程。通过对比试验，表明投加和不投加活性炭的反应器处理石化厂废水污泥颗粒化时间分别为３９ｄ和６２ｄ。投加活性炭反应器的颗粒污泥粒径也较大，最大ＣＯＤ去除率在８６％以上。并且投加活性炭反应器的有机负荷为不投加的２倍，运行效果更稳定。This paper indicated a new way to speed up granulation in UASB reactor by adding GAC. The results of experiment on UASB reactor with and without GAC treating effluence from Petrochemical plant showed that the time of sludge granulation in the reactors with add without GAC were 39 days and 63 days resistively. The sludge pellet in the reactor with GAC had larger diameter than one in the reactor without GAC, and maximum COD removal rate was above 86%.Organic load of reactor with GAC was 2 times larger than the reactor without GAC.The reactor with GAC became more steady in process.
