Wastewater, mainly from beer malt shop (wheat wastewater Baptist), glycosylated workshop (glycosylated, filter wash water), fermentation plant (fermentation tank washing, washing water filter), filling plant (bottle washing, sterilizing and wastewater outflow broken bottle beer), and the production such as cooling water. Change the water quality and the scope of its general: pH = 5.5 ~ 7.
0 (micro-acid), water temperature is 20 ~ 25 ℃, CODCr = 1200 ~ 2300mg / L, BOD5 = 700 ~ 1400mg / L, SS = 300 ~ 600mg / L, TN = 30 ~ 70mg / L. 1t of water for every beer production capacity of waste water 10 ~ 20m3, an average of about 15m3, beer nationwide in emissions of waste water at more than 250 million m3. Beer by the organic content of wastewater can be divided into 3 categories: ① freezer such as clean waste water cooling water, cooling water, such as wort. Basically, this kind of non-contaminated wastewater.
② clean water rinse yeast such as water, bottle-washing water, production of devices such as clean water, such waste water pollution are subject to varying degrees. ③ slag containing liquid waste such as wheat bad, hot and cold coagulum. The remaining yeast and so on, such a large number of organic wastewater containing suspended solids. The main sugar industrial waste beer category, alcohols and other organic material, the higher the concentration of organic matter, although the drug-free, but easy to corruption, into the water body to consume a large amount of dissolved oxygen, water environment causing serious harm.
Biochemical methods commonly used in activated sludge process has, biofilm, the combination of anaerobic and aerobic method, acid hydrolysis combined with a variety of SBR treatment process. Such treatment methods and technology have their own characteristics and deficiencies, but their success has more experience. At present, there are many new treatment methods and technology optimization portfolio and is being tested, and some have achieved the desired results, will soon be applied in practice. At present, the main brewery wastewater treatment process has the following: 1.
Acidification-SBR method brewery wastewater treatment 2.UASB-aerobic contact oxidation process of brewery wastewater treatment 3. Bio-contact oxidation treatment of brewery wastewater 4. UASB reactor loop + oxidation ditch process brewery wastewater treatment 5.UASB + SBR Act of beer 6.IC-CIRCOX wastewater treatment of brewery wastewater treatment process 7. new contact oxidation treatment of brewery wastewater
Beer, one of the main characteristics of wastewater BOD5/CODCr values are high, generally at 50% and above, there is very conducive to biochemical treatment, while biochemical and general physico-chemical treatment method, chemical method comparison: First, deal with more mature technology; are two efficient treatment, CODCr, BOD5 removal rate high, usually ranging from 80% to 90%; are three low-cost treatment (operation cost the province). Brewery wastewater treatment: China's beer wastewater treatment processes and technologies for a large number of research and exploration, the treatment of brewery wastewater to the various aspects of testing, research and practice, has been proven successful experience, and gradually formed a mainly biochemical, biochemical and physico-chemical treatment process of combining.
啤酒废水主要来自麦芽车间（浸麦废水）,糖化车间（糖化,过滤洗涤废水）,发酵车间（发酵罐洗涤,过滤洗涤废水）,灌装车间（洗瓶,灭菌废水及瓶子破碎流出的啤酒）以及生产用冷却废水等.其水质及变幅范围一般为：pH=5.5～7.0(显微酸性),水温为20～25℃,CODCr=1200～2300mg/L, BOD5=700～1400mg/L, SS=300～600mg/L, TN=30～70mg/L.水量为每生产1t啤酒废水排放量为10～20m3,平均约15m3,目前全国啤酒废水年排放量在2.5亿m3以上.
啤酒废水按有机物含量可分为3类：①清洁废水如冷冻机冷却水,麦汁冷却水等.这类废水基本上未受污染.②清洗废水如漂洗酵母水、洗瓶水、生产装置清洗水等,这类废水受到不同程度污染.③含渣废水如麦糟液、冷热凝固物.剩余酵母等,这类废水含有大量有机悬浮性固体.啤酒工业废水主要含糖类,醇类等有机物,有机物浓度较高,虽然无毒,但易于腐败,排入水体要消耗大量的溶解氧,对水体环境造成严重危害.

啤酒废水的主要特点之一是BOD5/CODCr值高,一般在50%及以上,非常有利于生化处理,同时生化处理与普通物化法、化学法相比较：一是处理工艺比较成熟；二是处理效率高,CODCr、BOD5去除率高,一般可达80%～90%以上；三是处理成本低(运行费用省).
啤酒废水处理:
我国对啤酒废水的处理工艺和技术进行了大量的研究和探索,对啤酒废水的处理进行了各方面的试验、研究和实践,取得了行之有效的成功经验,逐渐形成了以生化为主、生化与物化相结合的处理工艺.生化法中常用的有活性污泥法、生物膜法、厌氧与好氧相结合法、水解酸化与SBR相组合等各种处理工艺.这些处理方法与工艺各有其特点和不足之处,但各自都有较为成功的经验.目前还有不少新的处理方法和工艺优化组合正在试验和研究,有的已取得了理想的成效,不久将应用于实践中.
目前来说,主要的啤酒废水处理有以下几种工艺：
1.酸化—SBR法处理啤酒废水
2.UASB—好氧接触氧化工艺处理啤酒废水
3.生物接触氧化法处理啤酒废水
4.内循环UASB反应器＋氧化沟工艺处理啤酒废水
5.UASB+SBR法处理啤酒废水
6.IC-CIRCOX处理工艺处理啤酒废水
7.新型接触氧化法处理啤酒废水
