The degree of the design is in a preliminary phase. The main distinguishing feature of the beer waste water is that it contains the massive organic matters, so it belongs to the high concentration organic waste water, therefore its biochemical oxygen demand is also high. The water which needs to treatment in the beer waste water treatment plant is 5000, regardless of the specified future development. Various target in the raw waste water is: the concentration of BOD is 800 mg/L , the concentration of COD is 1400 mg/L , the concentration of SS is 350 mg/L，and pH is 6～10 . For the beer waste water's BOD is high, it could pollute the environment if drained before treatment, so it request the beer waste water which drained must be strictly treated to the two effluence standard in the country, which is as following: BOD ≤ 20 mg/L , COD ≤ 100 mg/L , SS ≤ 70 mg/L ,pH = 6～9 . This paper analyzes the generation processes of wastewater, the major contaminats and their major sources in beer production. It also introduces the primary biological processing techniques of aerobic and anaerobic treatment. According to the product scale of beer brewery, the main standard of draining water\natural materials, and so on, the main process technology of the beer waste water disposal station is defined as UASB + CASS .Practice of project indicate, when COD of wastewater reduces from 1400mg/l to 50~100mg/l, BOD reduces from 800mg/l to 20mg/l, SS reduces from 350mg/l to 70mg/l, so that drains out can reaches the Standard. The technological process of this design is: Beer waste water → Screens → The sewage lift pump house → shuili shai → Regulates tank → Reaction tank of UASB → Tank of CASS → Treatment water This technology of wastewater treatment has many traits. Such as, well-knit structure, pithy quick control, lasting attacked, less sledge capacity. Practice indicates that the composed craft has reliable function, its investment is little, and its running and management is uncomplicated. Key words: beer waste water, UASB, CASS Ⅰ
