摘　　要：内循环(IC)反应器的启动控制较复杂,控制因素与水质条件密切相关。总结了郑州大学实际工程经验,对不同水质条件下IC反应器的启动进行了比较、讨论。启动结果表明:金霉素废水和酒精废水采用的初始COD污泥负荷分别为0.050、0.075kg/(kg·d),每周分别将负荷提高到上一周的1.118、1.230倍,分别经过168、112d完成启动,启动完成后COD容积负荷分别达到5.02、11.48kg/(m3·d),COD去除率分别达到80%、95%。The start-up of internal circulation （IC） reactor is complicated, and the controlling factors are closely related to water quality. The experiences based on the real projects done by Zhengzhou University are summarized, and the starts-up of IC reactor made by using wastewater with different water quality are compared and discussed. The start-up demonstrates that the initial COD sludge load adopted for the aureomycin wastewater and alcohol wastewater are 0.05,0.075 kg/（kg·d） respectively. The load increases 1.118, 1.230 times a week. The starts-up will be completed after 168, 112 d respectively, and the final COD volume load reaches 5.02, 11.48 kg/（m^3· d）respectively and the COD removal rate reaches 80% and 95% resoectivelv.
