摘　　要：在IC反应器的启动过程中,初始容积负荷控制在9.5kgCOD.(m3.d)-1左右,出水pH值6.5~7.8,维持反应器的碱度1000mgCaCO3/L^5000mgCaCO3/L,进水COD浓度1000~6000mg/L,以及采用脉冲进水方式,可增强污泥的活性和沉降性能加快厌氧污泥的颗粒化进程,从而加快IC反应器的启动。In the process of starting IC reactor, to control the initial volume loading rate is about 9.5kg COD · （m^3 · d） ^-1, the pH value of the treated water can reach range from 1000mgCaCO3 to 5000 mgCaCO3 and the COD 6. 5 - 7. 8. To keep the alkalinity in IC reactor in the concentration of input water among 1000 - 6000 mg/L with impulse input water mode, these steps will improve the activity and sedimentation of granular sludge, which can quicken the startup process of IC reactor.
