- Abstract
This paper studies the performance of a gas-Iiquid-solid fluidizedbed bioreactor(FBB)for the slaughter treatment.The results show that the COD removal rate is higher than 80% when COD concentration in the influent waste-water is about 1000mg/1 and the hydrauIic residence time(HRT)is 124.5 minutes.n the experiments,the crushed granular shale used as media in FBB has advan-tages of slight weight,easy fluidization,ease of attaching by microbes and cheap-ness.
