摘要: 为解决内循环厌氧反应器在对低浓度有机废水处理时，因产气量不足、内循环量小而不能正常运行的问题，提出了强制循环反应器的概念，给出了设计方法。以低浓度、碱性印染工业废水为研究对象，进行了强制循环厌氧反应器的启动与运行的研究，得出了该反应器的最佳HRT和最佳外加循环量。结果表明：在高硫、低性状絮状厌氧泥为接种泥情况下，最佳外循环流量1 m3/h，最佳HRT为7 h时，FCR出水的T-COD和S-COD去除率分别为53.6%和58%。

Abstract: To solve the problem that internal circulation anaerobic reactor couldn’t operate regularly when it was used to treat wastewater with low strength of organic wastewater due to little gas production and the small amount of circulation， a new concept and design method of forced circulation reactor were presented. It was used to treat a printing and dyeing wastewater with low strength and slight alkaline. The parameters， such as activated time， optimal HRT and circulation amount， were studied when the mud with high sulfur and low flocculent was inoculate mud. The results show that the optimal external circulating flow was 1 m3/h， the best HRT was 7 h. Under the optimal conditions the T-COD and S-COD removal rates of FCR were 53.6% and 58%，respectively.
