摘　　要：全球性资源紧缺与资源节省空间不断收窄是当前社会面临的挑战之一,从废弃物中回收资源以缓解资源短缺压力一直以来是各个行业的研究热点。啤酒废水作为一种有机物浓度高且无毒无害的废水,在污水处理与资源化领域得到了广泛关注。文章以青岛啤酒二厂为例,通过对啤酒生产过程中各个工序的废水水质分析,定向选择糖化工序中的高浓度有机废水作为污水生物处理过程中的反硝化外加碳源,补充到污水站AAO污水处理工艺中。试验结果表明,随着高浓度啤酒废水添加浓度的增加,总氮去除率增高,总磷去除率变化不明显;当外加碳源质量浓度为300 mg/L时,总氮平均去除率为85.51%,总磷平均去除率为71.65%,脱氮除磷效果较好。该研究不仅解决了污水生物处理和反硝化脱氮碳源不足的问题,也降低了啤酒企业的废水处理成本,实现经济效益和社会效益双赢,为啤酒废水资源化方法的实际应用和进一步研究提供思路和参考。The global resource shortage and the shrinking resources save space is one of the major challenges for the human society.Resources recovery from waste or side-product of manufacturing to ease the pressure of resource shortage has always been a hot topic in various industrial sectors.As a kind of high organic concentration wastewater with poisonless and harmless,brewery wastewater has attracted attentions in the field of wastewater treatment and resource recovery.Qingdao Brewery No.2 was been an example in this study,the wastewater quality in each stage of beer production was analyzed.The high concentration organic wastewater from saccharification process was selected as the denitrification plus carbon source in the biological treatment of wastewater and added to the treatment process of AAO wastewater station.Results showed that,with the increase of the concentration of high concentration beer wastewater,the total nitrogen removal rate increased,and the total phosphorus removal rate did not change significantly.When the applied carbon source mass concentration was 300 mg/L,the average removal rate of total nitrogen was 85.51%,and the average removal rate of total phosphorus was 71.65%,and the removal effect of nitrogen and phosphorus was good.The problem of insufficient carbon source of municipal domestic wastewater treatment was solved in this research,and the wastewater treatment cost of beer enterprises was reduced as well.Therefore,this application had achieved satisfactory economic and social benefits,which provided ideas and references for the practical application and further research of brewery wastewater recycling method.
