主　　题：hydrolyzation multilevel oxidation excess sludge reduction 

摘      要：During brewery wastewater treatment by a hydrolyzation-food chain reactor(FCR)system,sludge was recycled to the anaerobic *** the function of hydrolyzation acidification in the anaerobic segment and the processes of aerobic oxidation and antagonism,preda-tion,interaction and symbiosis among microbes in multi-level oxidation segment,residual sludge could be reduced *** 6-month dynamic experiments show that the average chemical oxygen demand(COD)removal ratio was 92.6% and average sludge production of the aerobic segment was 8.14%,with the COD of the influent at 960–1720 mg/L and hydraulic retention time(HRT)of 12 *** the producedsludge could be recycled and hydrolyzed in the anaerobic segment,no excess sludge was produced during the steady running for this system.
