水解酸化_生物接触氧化法处理啤酒污水（Treatment of beer wastewater _ hydrolysis acidification biological contact oxidation process）

水解酸化_生物接触氧化法处理啤酒污水（Treatment of beer wastewater _ hydrolysis acidification biological contact oxidation process） Treatment of brewery wastewater by hydrolytic acidification and biological contact oxidation process Shandong Light Industry Design Institute (Shandong, Jinan, 250014).. Zhou Huanxiang The application of hydrolytic acidification and biological contact oxidation process for brewery wastewater treatment has proved that the method has high treatment efficiency, stable effluent quality and running cost Low volume, high load, convenient debugging and operation. Better social and environmental benefits can be achieved. .. Beer sewage treatment.. anaerobic hydrolysis acidification.. biological contact oxidation.. coagulation air flotation .. Beer production process, sewage discharge is very large, every production of 1 t Beer produces 12~ 20 m3 sewage. Brewery wastewater and other industries Different pollution components are harmful and non-toxic, mainly organic pollutants The main ingredients of sewage contain saccharifying wheat grains, sugars, pectin, hops and ferment Maternal residues, proteins, cellulose and other organic substances and a small amount of inorganic salts. According to relevant data, the BOD5 value of beer sewage is 650 ~! 800 mg/ L, CODCr values 1 000~, 1800 mg/ L, pH values 6~ 8 belongs to medium concentration organic wastewater 1!. If not dealt with directly discharged It will seriously pollute natural water bodies and endanger agriculture, fisheries and even human beings Normal life. Shouguang Lu Lu Brewery Co., Ltd., Shandong, is a Sino foreign joint venture, After the expansion in 1993, an annual output of 80 thousand T beer, beer wastewater discharge Volume 3000 m Three / D, a sewage treatment station was constructed in 1994 By anaerobic hydrolysis acidification. Biological contact oxidation treatment, BOD5 60, mg/, L, CODCr. 150, mg/, L, SS. 200, mg / L, PH6~ 9, the water quality reached the national current # emission standard level
