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。

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.

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最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）中的一级（新扩改）标准，即：COD＜100mg/L, BOD＜20mg/L, SS＜20mg/L。

1 production process and water quality

The main sources of waste water are the saccharification and filtration washing water in the saccharification workshop; Fermentation tank washing and filtration washing water; Bottling, sterilization and beer bottles; Cooling water and finished workshop washing water, etc.

Design water quality: COD = 2500mg/L, BOD = 1800mg/L, SS = 400mg/L.

Due to the water yield of final discharge after processing the whereabouts of the urban sewage pipeline, so "integrated wastewater discharge standard" (GB8978-1996) in the primary (new expansion change) standard, namely: COD < 100 mg/L, BOD < 20 mg/L, SS < 20 mg/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。

2 treatment process

The wastewater of this project is a high concentration organic wastewater, which can be biochemical and suitable for biochemical treatment. The combination process of anaerobic UASB and good oxygen SBR was adopted in the design of the process.

In order to avoid the influence of the following UASB, the two stage pretreatment of the grille and solid-liquid separation machine was used for the characteristics of waste water suspension.

3 process flow

This engineering process

Wastewater after fine grille to remove impurities, first through the solid liquid separator large particles suspended solids removal of wheat bran, into collecting well and the submersible sewage pump to ascend into adjusting pool, adjusting water quality after secondary to ascend into UASB reactor. 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. The upper cleaning fluid and the dewatering machine room cleaning fluid flow back to the collecting well. Biological organic fertilizer is made after the treatment of the waste water after dehydration or compost.
