Abstract

Abstract:

Based on the comprehensive analysis of the characteristics of the wastewater from beer production, combining with the original technology in water treatment stations and a number of practical experiences of similar waste-water plants, it is proposed that the combined process, UASB+CASS, is to be used for the treatment of beer waste-water.The running results show that all the effluent COD, BOD₅, SS, and NH₃-N can meet the requirements specified in Level l of the Discharge Standard of Pollutants for Beer Industry(GB 19821-2005).The effluent, animal and plant oils, and anionic surfactant can meet the requirements specified in Level l of Integrated Wastewater Discharge Standard(GB 8978-1996).Using the combined process for the treatment of wastewater from beer production is technically and economically feasible.

Key words: beer wastewater, upflow anaerobic sludge bed, cyclic activated sludge method

摘要：

通过对啤酒生产制作废水特点的综合分析,结合原有污水处理站工艺及多家同类污水站的实践经验,提出采用UASB+CASS组合工艺处理啤酒废水。运行结果表明:出水COD、BOD₅、SS、NH₃-N均满足《啤酒工业污染物排放标准》(GB 19821-2005)一级标准,出水动植物油、阴离子表面活性剂满足《污水综合排放标准》(GB 8978-1996)一级标准,采用该组合工艺处理啤酒生产废水,在技术和经济上可行。
