A/O工艺处理啤酒废水工程设计

Design of beer wastewater treatmen by A/O process

采用A/O工艺处理高浓度的啤酒废水,结果表明:出水CODCr、BOD5和SS的平均去除率分别达到了88.7%～92.8%、90.3%～95.4%和86.2%～90.0%,达到了啤酒工业污染物排放标准。该工艺具有流程简单、废水停留时间短、水质水量适应范围广、有机物降解效率高、不产沼气和防止污泥膨胀等优点。

The A/O process has been applied to the treatment of beer wastewater with high concentration. The results show that the average removal rates of CODCr, BOD5 and SS have reached 88.7%-92.8% ,90.3%-95.4% and 86.2%-90.0% , respectively, which met the requirements of discharge standard of pollutants for beer industry. It is characterised by simple process, short HRT, wide adaptive range of water quality, efficient organism degradability, no marsh gas, and little sludge bulking.
