Startup Characteristics of Internal Circulation (IC) Anaerobic Reactor in Treating Juice Wastewater

摘要：

We studied several aspects of an Internal Circulation (IC) anaerobic reactor in treating juice wastewater. Including Start-up and running characteristics, The results showed that under the circumstance of increasing COD concentration gradually and reducing hydraulic retention time (HRT) to enhance the volume load, reactors sludge bed zone was filled fully by granular sludge with good settling property little by little as reactor run.In the bottom of the reactor, granular sludge particle size in 2-3mm was predominant. And particle size of all the granular sludge under the sludge bed zone was bigger than that of the upper. When the influent COD concentration was about 9000mg/L, HRT reduced to 8.3 hours. Under the Circumstance of the volume load in 27.42kgCOD/m3.d,COD removal rate kept above 90%. The VFA stabled at less than 400mg /L.
