用UASB装置处理白酒生产企业锅底水

Bottom Pot Water in Distilleries Treated by UASB Equipment

白酒生产产生的锅底水含有:①由酒醅、糟醅、料醅漏入锅底产生的污染物;②高沸点酸类、酯类、糖类、醇类等污染物;③酒尾加入锅底复蒸产生的污染物等。锅底水的直接排放会引起严重的环境污染。采用酸化水解、UASB厌氧生物反应器、生物接触氧化工艺处理锅底水,可达到GB8978-1996《污水综合排放标准》一级指标要求,实现达标排放。(孙悟)

The bottom pot water in distilleries mainly containes the following substances： ①The pollutant by the leakage of fermented grains, distiller＇s grains and raw materials in bottom pot;②The pollutant of high boiling point acids, esters, sugar and ethanol ;③The pollutant produced by the steaming of ending liquor in bottom pot etc. The direct drainage of bottom pot water would induce seriously environmental pollution. The bottom pot water treated by acidolysis, UASB aerobic biologic reactor,or biologic contact oxidation technique could be drained because it met the index requirements of GB8978-1996 Sewage Drainage Standards. （Tran by YUE Yang）
