Is increasingly highlighting the attendant environmental problems such as wastewater from brewery production has also increased. In the analysis of Brewery wastewater with a very high concentration of organic matter in waste water, BOD/COD high biodegradability is very good. High concentrations of Brewery wastewater treatment is a common research focus in the various countries in the world now. Through many years the general method which in the world uses at present for the beer waste water processing industry unceasing improvement is, the upper reaches -like tire of march which oxygen sludge bed (UASB) and cycle of operations active sludge law (CASS) combines to beer waste water processin This design brewerydesign scale 6000m/d, enters water COD:1200~2400mg/L,900~1200 mg/LSS:400~500mg/L to act according to the correlation data and the correlation experiment designated the craft is: Grill - pneumatic control sedimentation pond - - UASB--CASS enables the waste water which processes to achieve Beer Industry Pollutant Emissions Standard (GB19821-2005) table 1 beer enterprises emissions standard. When uses this craft processing can produce the methane in the UASB pond, this design deference circulation use and the zero pollution emissions principle comes out thus the methane carries on the recycling use, the methane uses in the brewery
