The degree of the design is ina preliminary phase. The main distinguishing feature of the beer waste water is that it contains the anic matters, so it belongs to the high anic waste water, therefore it's biochemical oxygen demand is also high. The water which needs to treatment in the beer waste water treatment plant is 7500m 3 /L, regardless of the specified future development. Various target in the raw waste water is: the concentration of BOD is≤ 1500mg/L, the concentration of COD is≤ 2600mg/L, the concentration of SS is between 332 and 450mg/L. For the beer waste water's BOD is high, it could pollute the enviro n ment if drained before treatment, so it request the beer waste water which drained must be strictly treated to the effluence standard which is as following: BOD ≤6 0mg/ L, COD ≤ 100mg/ L, SS ≤5 0mg/ L. After the analysis, the quality of this processing water belongs to the waste water that easy biology degrade and not have the obvious poison, could use two levels of biological treatments to cause the water drained meet the designated standard. First level of processing mainly uses the physical met
