摘　　要：设计了双区厌氧反应器:下部污泥膨胀区在强水力作用下,消除了UASB的配水问题,加强了传质和预处理能力,刺激了厌氧微生物的生长和颗粒化进程;上部精处理区颗粒污泥生长条件好.实现了2.3倍的UASB反应器容积负荷.现场毒性试验表明:双区厌氧反应器比IC反应器受毒恢复更快.The authors of this paper design a UASB reactor with two sections. The rapid mixed section has the greater hydraulic gradient than the slow-moving section. This solves the problems of water distribution of UASB and the pretreatment, which stimulates the growth of sludge and the course of granulation. The sludge granulation in the slow-moving section has good yield condition, and COD is removed efficiently and stably. UASB reactor with two sections in the location site is better than IC reactor in toxicity tests.
