天通水处理设备污水处理设备啤酒厂废水处理设备工程案例
工业废水在城市污水中的比重,因城市工业生产规模和水平而不同,可从百分之几到百分之几十.其中往往含有腐蚀性、有毒、有害、难以生物降解的污染物.因此,工业废水进行处理,达到一定标准后方能排入生活污水系统.生活污水和工业废水的水量以及两者的比例决定着城市污水处理的方法、技术和处理程度.
一 工程概况
某啤酒公司以大麦和大米为主要原料，辅以啤酒花和鲜酵母制造啤酒，年产啤酒10万吨。废水处理工程的设计规模为3500m³/d，合146m³/h。
二 处理工艺
1 生产工艺及水质
废水主要来源有：糖化车间的糖化、过滤洗涤水；发酵过程的发酵罐洗涤、过滤洗涤水；灌装过程洗瓶、灭菌及破瓶啤酒；冷却水和成品车间洗涤水等。
设计进水水质为：COD＝2500mg/L, BOD＝1800mg/L, SS＝400mg/L。
由于处理后的出水量终排放的去向是城市污水管道，因此执行《污水综合排放标准》（GB8978-1996）中的（新扩改）标准，即：COD＜100mg/L, BOD＜20mg/L, SS＜20mg/L。
2 处理工艺
本工程废水中属高浓度有机废水，可生化性好，适合采用生化处理。通过工艺的选择比较设计中采用了厌氧UASB和好氧SBR的组合工艺。
针对废水悬浮物较多的特点，采用格栅和固液分离机两级预处理进行去除，避免对后续UASB的影响。
3 工艺流程
本工程工艺流程
废水先经细格栅去除杂物后，经固液分离机去除麦麸等大颗粒悬浮物，后进入集水井，由潜污泵提升进入调节池，调节水量水质后经过二次提升进入UASB反应器。UASB反应器处理后的出水进入好氧SBR曝气池，处理后达标排放。设计中UASB前设有酸碱调节设施。曝气池产生的剩余污泥重力排入调节池，有调节池提升进入厌氧池。从厌氧UASB池排出的剩余污泥进入污泥浓缩池，经浓缩后由带式污泥脱水机进行脱水处理。浓缩池的上清液和脱水机房清液流回集水井。脱水后的污泥外运填埋或经堆肥等处理后制成生物有机肥。

In the proportion of urban sewage, industrial wastewater for the city's industrial production scale and level, but from a few percent to percentage decades. Which often contain corrosive, poisonous, harmful, are difficult to biodegradable pollutants. Therefore, industrial waste water must be treated, reach a certain standard rear can into the sewage system. Life sewage and industrial waste water amount and proportion of the two determines the urban sewage treatment methods, technology and level.
Project overview
A beer company, with barley and rice as its main raw materials, is supplemented with beer and fresh yeast, and produces a beer of 100,000 tons a year. The design scale of wastewater treatment works is 3500m cubed/d, which is 146m cubed/h.
Two-process process

After treatment of UASB reactor, the water outlet enters good oxygen SBR aeration tank, and after treatment, it is discharged. In the design, UASB is equipped with acid and alkali adjustment facilities. The residual sludge caused by aeration pool is pumped into the regulating pool, and the adjustment pool is raised to the anaerobic pool. The residual sludge discharged from anaerobic UASB pool enters the sludge thickening pool and is condensed and then dehydrated by the belt sludge dehydrator.
