天通水處理設(shè)備啤酒廠廢水污水處理一站式服務(wù)

工業(yè)廢水在城市污水中的比重,因城市工業(yè)生產(chǎn)規(guī)模和水平而不同,可從百分之幾到百分之幾十.其中往往含有腐蝕性、有毒、有害、難以生物降解的污染物.因此,工業(yè)廢水必須進行處理,達到一定標(biāo)準(zhǔn)后方能排入生活污水系統(tǒng).生活污水和工業(yè)廢水的水量以及兩者的比例決定著城市污水處理的方法、技術(shù)和處理程度.

一 工程概況

某啤酒公司以大麥和大米為主要原料，輔以啤酒花和鮮酵母制造啤酒，年產(chǎn)啤酒10萬噸。廢水處理工程的設(shè)計規(guī)模為3500m3/d，合146m3/h。

二  處理工藝

1 生產(chǎn)工藝及水質(zhì)

廢水主要來源有：糖化車間的糖化、過濾洗滌水；發(fā)酵過程的發(fā)酵罐洗滌、過濾洗滌水；灌裝過程洗瓶、滅菌及破瓶啤酒；冷卻水和成品車間洗滌水等。

設(shè)計進水水質(zhì)為：COD＝2500mg/L, BOD＝1800mg/L, SS＝400mg/L。

由于處理后的出水量最終排放的去向是城市污水管道，因此執(zhí)行《污水綜合排放標(biāo)準(zhǔn)》（GB8978-1996）中的一級（新擴改）標(biāo)準(zhǔn)，即：COD＜100mg/L, BOD＜20mg/L, SS＜20mg/L。

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

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 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.
