Study on Sludge Reduction during brewery wastewater treatment by hydrolyzation-FCR system
During brewery wastewater treatment by Hydrolyzation -FCR system, sludge was recycled to anaerobic segment. With the function of hydrolyzation acidification in anaerobic segment and the process of aerobic oxidation and antagonist, predation, biocenose, symbiose among microbes in multilevel oxidation segment, residual sludge could be reduced effectively. The 6 month dynamic experiment demonstrated that when COD of influent was 960- 1720mg/L, HRT was 12h, average COD removal ratio was 92.6％, and average sludge production of aerobic segment was 8.14％. Since the produced sludge could be recycled and hydrolyzed in anaerobic segment, non surplus sludge was produced during the steady running for this system. With no extra equipment added, this method could save the capital and running cost compared with others.
