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 .A...
