UASB+CASS组合工艺处理啤酒废水工程实例

Case study on the combined process,UASB+CASS for the treatment of beer wastewater

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。

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 wastewater plants,it is proposed that the combined process,UASB ＋CASS,is to be used for the treatment of beer wastewater. 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.
