1、 摘 要 随着青岛人口的增加和工业的迅速发展，废水的排放量也日益增加，啤酒废水 的排出大量，给环境造成了极大的威胁。本设计为*啤酒有限公司啤酒生产废水处理 站初步设计。啤酒废水水质的主要特点是含有大量的有机物，属高浓度有机废水，故 其生化需氧量也较大。该啤酒废水处理厂的处理水量为12000m 3/d，不考虑远期发展。 原污水中各项指标为：BOD 浓度为 850mg/L，COD 浓度为 1340mg/L，SS 浓度为 1100mg/L，NH3-N 为29mg/L，TP为7mg/L，pH=6.58.5。因该废水BOD值较大， 不经处理会对环境造成巨大污染，故要求处理后，出水水质达到国家啤酒工业污染

2、 物排放标准 （GB198212005）中啤酒生产废水排放限值：COD80 mg/L，BOD 20 mg/L，SS70mg/L，TP3mg/L，NH3-N15mg/L，pH=69。 本文分析了啤酒生产中废水产生的环节，污染物及主要污染来源，并从好氧、厌 氧生物处理两方面来考虑了废水治理工艺， 提出了UASB+CASS 的组合工艺流程。 可 将废水COD由1340 mg/L降至80 mg/L以下，BOD从850mg/L降至20 mg/L以下， SS 由 1100 mg/L 降到70 mg/L 以下，出水符合标准。 关键词：关键词：啤酒废水 厌氧处理 好氧处理 UASB CASS Abstract

3、 With the development of industry and the growth of population, a large amount of wastewater was discharged into water-body in QinDao. Emit large amounts of brewery wastewater to the environment caused a great threat. The preliminary design is one brewery wastewater treatment of LaoChuan Brewery Com

4、pany in ShanDong. The main distinguishing feature of the brewery wastewater is that it contains the massive organic matters, so it belongs to the high concentration organic wastewater, therefore its biochemical oxygen demand is also high. The water which needs to treatment in the brewery wastewater

5、treatment plant is 12000m3/d, regardless of the specified future development. Various target in the raw waste water is: the concentration of BOD is 850 mg/L , the concentration of COD is 1340 mg/L , the concentration of SS is 1100 mg/L，the concentration of NH3-N is 29 mg/L， the concentration of TP i

6、s 7mg/L，and pH is 6.58.5 . For the brewery wastewaters BOD is very high, it could pollute the environment if drained before treatment, so it request the brewery wastewater which drained must be strictly treated to the Pollutant emission standards of the beer industryGB198212005）which is as following: COD80 mg/L， BOD20 mg/L，SS70mg/L，TP3mg/L，NH3-N15mg/L，pH=69。 This paper analyzes the generation processes of wastewater, the major contaminats and their major sources in beer pro
