Abstract:In view of the problem that the pollutants in the brewery wastewater affect the activity of anaerobic granular sludge， taking the brewery wastewater of a domestic brewery company as the research object， single variable method and the control variable method were adopted， the activity of anaerobic granular sludge was characterized by its gas production performance， the effects of brewery wastewater， brewing and packaging mixed water， packaging workshop chemicals and waste yeast on the activity of anaerobic granular sludge were studied. The results showed that the brewing wastewater had little effect on the anaerobic granular sludge activity ，while the packaging workshop wastewater had a strong inhibitory effect on the anaerobic granular sludge activity because it contained bottle washing agents and lubricants. When the mass concentration of bottle washing agent K was 20 mg/L， the gas production of anaerobic granular sludge decreased by more than 50% . When itincreased to 100 mg/L，the gas production of anaerobic granular sludge decreased about 70% . When it was over 120 mg/L，the gas production of anaerobic granular sludge was almost zero. Yeast also significantly inhibited the activity of anaerobic granular sludge. In beer production， the use of bottle washing agent， lubricant and yeast should be minimized to reduce the inhibition of anaerobic granular sludge activity and maintain the high efficiency of anaerobic reaction. The study provides a reliable theoretical basis for the anaerobic treatment of brewery wastewater.
