在過去二十年的醞釀產(chǎn)業(yè)呈現(xiàn)出越來越意識環(huán)境保護和可持續(xù)生產(chǎn)流程需要。實施ISO14001證更嚴格的環(huán)境立法已在醞釀產(chǎn)業(yè)的重要驅(qū)動的投資在生物污水治療在治療中的作用進行了討論生物污水別注意是考慮到聯(lián)合厭氧/好氧處理合厭氧預處理好氧后處理集成這兩個進程之間的優(yōu)點從而減少了能源消耗（凈能源生產(chǎn)），減少生物污泥生產(chǎn)和有限空間要求，都具有重要意義。這種組合使大大節(jié)省了運營成本較完整的有氧治療不影響規(guī)定的排放標準。主題詞啤酒廢水，物處理厭氧，好氧啤酒廢的組成啤酒的質(zhì)量和數(shù)量的污水，因為它可以大幅波動取決于多方面的，不同的工藝處理的麥汁發(fā)生在啤酒廠（原料制備，發(fā)酵，過濾，環(huán)丙沙星，包裝生產(chǎn)是關系到具體的耗水量（水表示的/氧啤酒釀制水的一部分，出售啤酒的產(chǎn)品通過和一部分是失去蒸發(fā)此啤酒廢水的比例往往是hl水氫氧小于啤酒的比例。啤酒廢水中的有機成分（化學需氧量表示）通常容易可生物降解的，因為這些主要是由糖酸，可溶性淀粉，酒精，揮發(fā)性脂肪酸，等，這是說明了相對較高/COD的比。啤酒廠固體（技術支持服務表示為要包括酒糟，硅藻土，廢酵母和'熱'）。啤酒廢水的值大多取決于使用的數(shù)量和類型的化學品在總督察單位（如燒堿磷酸硝酸等磷水平主要取決于原料和材料處理金額目前用于污水酵母英寸高架磷水平，也可以是結果含有磷化學品使用單位的總督察。放電要污水排放限值的一個釀酒廠必須遵守取決于當?shù)氐沫h(huán)境立法。很明顯的限制，排放的情況下履行了市政下水道是少即是嚴厲的，當污水被排入一個敏感的接收面水體（河流，湖海等除有機物（的化學需氧量要求廢水）從重要的是避免在無氧條件接收水域。如氮素N和磷的，應刪除，以避免藻類開花受納水體生態(tài)系統(tǒng)的干擾表二載列的一些指示放電限額一般適用于歐歐盟理事會的接收面水體。13

實際排放限值為每個位置可能有所不同，地區(qū)和國家。生物廢水處理系統(tǒng)在生物處理系統(tǒng)之一，能分辨厭氧（沒有氧氣）和好氧（帶空氧氣供應的進程厭氧處理特點是生物轉(zhuǎn)化的化學需氧量機化合（成沼（主要是甲烷70-85％第一卷和二氧化碳硫化氫％的卷的痕跡好氧處理（空氣）氧氣供給水氧化成二氧化碳和化學需氧量。這兩種生物過程產(chǎn)生新的污泥）生物量?？偟幕痉磻牵簠捬酰夯瘜W需氧量甲烷二氧化碳厭氧生物。有氧：化學需氧量一氧化碳+好氧生物量在放電的情況下到下水道的污水厭氧處理后由一個簡單的拋光步驟可以是一個有吸引力的替代好氧處理。的速度開發(fā)新的高上流式反應器采用高水力速度允許選擇性沖刷啤酒固體（硅藻土，trub，酵母時保留生物的生物量是有保證的。允許處置問題，而無需污泥污水排入市政下水道。在多數(shù)案件排放到地表水體（如河流，湖泊或海洋）啤酒要遵守更嚴格的限制只比治療厭氧菌可以通過。厭氧處理，不應被視為替代治療以有氧，但可用在互補的方式。當用作組合，優(yōu)勢的兩個進程是集成的。厭氧預處理之后，好氧處理后，將導致積極的能量平衡，減少污泥產(chǎn)量，節(jié)省空間。當排入地表水體，厭氧預處理后加上后續(xù)好氧治療被認為是當時的解決方案。厭氧處系統(tǒng)有效的生物量是工業(yè)污水處理一個很高的生物治療要求。該系統(tǒng)的生物處理能力取決于：-生物量（濃度，體積等）及-生物質(zhì)的生物活性較高的生物量VS/m3表示為公斤）和生物活性（表示為化學需氧量公斤公斤VS.d）較高的轉(zhuǎn)化率公的反應器系統(tǒng)（/d）。生物處理系統(tǒng)，因此可以歸入這些推廣方式：14

-生物質(zhì)保留（安寧）-生物質(zhì)廢水接觸（混合，湍流）最簡單的厭氧系統(tǒng)是所謂的瀉湖CSTR反應器（連續(xù)攪拌反應器）。于這些反應堆沒有特別的固定系統(tǒng)，污泥污泥保留時間等于水力停留時間。作為結果，懸浮微生物濃度很稀，因此生物處理能力是有限的。這些系統(tǒng)主要用于沼氣池的污泥和污水幾乎適用于治療厭氧接觸過程是一個單位CSTR反應器與外部分離回部分污泥混合方式是通過鼓風機機械攪拌器或沼氣。由于稀釋的絮狀污泥和厭氧性質(zhì)的運作這些系統(tǒng)在相對低容積負荷率，而且不太喜歡適合低濃度工業(yè)廢水啤酒廢水的方法。厭氧過濾（AF污泥停留載體材料的使用上應該是生物質(zhì)增長于固定向承運人往往是有限的，暫停絮狀污泥仍然在很大程度上有助于反應堆的能力等。此一系統(tǒng)的缺點是易感因固體堵塞區(qū)廢水造成的'短'和死'反應堆在70代末的一類稱為厭氧UASB反應器（上流式厭氧泥毛毯）反應器的開發(fā)和行業(yè)應用首先由荷蘭糖。在UASB反應反應器的厭氧污泥床密集的廢水流模式在上升要是污泥性質(zhì)的顆毫米），具有優(yōu)良的沉降性能50/小時）。在頂部UASB反應器所謂的三相分離器分離沼氣和生物質(zhì)的廢水。1984，第一次高厭氧處理廠釀酒廠是一個建于巴伐利亞啤酒和荷蘭啤酒工廠1984年以前，巴伐利亞經(jīng)營一好氧活性處理廠（卡魯塞爾型）。繼續(xù)生產(chǎn)的增加使得有必要擴大污水處理廠的能力由于現(xiàn)有的有氧植物無法應付日益增加的污染負荷。飛行員試驗是測試這種生物降解性的比較?。?200-1700mgCOD/升冷（17-24三）廢水。試點成功后審判全面厭氧UASB應堆建成前減少了廢水處理的好氧處理負荷廠應堆是接種顆粒污泥從一家造紙廠和土豆加工工廠達到設計荷載兩個月的時間內(nèi)COD去除率為75-80％。治療后的厭氧實施前的生物質(zhì)沉降的好氧沒有明顯改善產(chǎn)能高液壓造成一個更穩(wěn)定的運行UASB反應器是目前世界上應用最廣泛的厭氧反應器系統(tǒng)啤酒廢水處理。即使UASB反應器完成他們的任務非常好多年，新的一代者的反應堆的釀造業(yè)在15

1990年年底開始成為流行即擴大高塔式反應器顆粒污泥等的FB（流化床）中，EGSB反應（床）IC（內(nèi)循環(huán)）反應器。鑒于流化床反應器的使用物流化床的載體材料上生長，EGSB反應器IC反應器使用顆粒厭氧污泥，UASB反應器完全相同。EGSB反應器是在應器的版本其實是一個垂直拉伸。UASB反應器通常建有4.5-6.5米高度的坦克反應堆高度EGSB反應IC分別是12-1616-24印造成更加降低了糧食。而像UASB反器EGSB反應分離的生物量，沼氣和廢1步三相反應器分離器在頂部時，IC反應器是由更復雜有個階段組成的反應堆設計“兩個應器頂部的其他每個”。該UASB應器獲得額外降低生產(chǎn)混合氣體通過一個內(nèi)部的循環(huán)，其驅(qū)動。雖然第一個分離器除去大部分的沼氣，湍流明顯減少，從而有效地分離器分離二從厭氧污泥廢水IC反應器的負荷率通常高達兩倍的UASB應器（15-30公斤的化學需氧量/米三四年，荷蘭喜力啤酒在書齋博世，是第一啤酒廠C反應器技術的應用在釀造業(yè)的IC應器已獲得一個重要的市場份額為41％，累計過去5年。好氧處系統(tǒng)相似的厭氧好氧反應器系統(tǒng)路系統(tǒng)可以被歸入保留這些反應堆安排和確保生物好氧接觸良好生物量和廢水。好氧污泥塘沒有特殊的固定系統(tǒng)，而不是通常所用的啤酒廢水的處理，因為這些系統(tǒng)都需要大面積的土地瀉湖往往在積累多年堅實的瀉湖要求成為清空后時期時間。好氧固定床和移動床反應器的生物材料載體上生長些系統(tǒng)不保留進水懸浮物此大多用作前，厭氧過濾器一樣，好氧固定床反應器容易堵塞的由于廢水中固體物質(zhì)或增長。此外，如果是沒有強制通風應用這些系統(tǒng)是眾所周知的原因可能由于沒有足夠的氣味排放氧化。移動床反應器通常有一個相對較高的能量消耗和污泥生產(chǎn)?；钚晕勰喾ㄊ亲畛Ｒ姷暮蛷V泛應用好氧處理技術工業(yè)污水。該技術是基于懸浮曝氣反應器好氧絮狀污泥，必要時氧氣混合曝氣機供應。除了壓縮的空氣或氧氣，大氣中水16

進入曝氣機械噴涂可用于氧氣供應。一種外部重力沉淀池污泥分離后遵循氣盆地。轉(zhuǎn)自凈化污水的好氧解除，而解決好氧污泥返回到曝氣池。好氧污泥往往是過剩脫水后，把垃圾填埋場。如果需要的曝氣池設置允許可以修改脫氮（硝化和反硝化作用）。使用活性污泥系統(tǒng)允許污水排放到河流和湖泊。最近所謂的空運反應器已經(jīng)制定出來升式反應器的水污泥混合物正在加緊對內(nèi)部傳閱（s的空運方式一建立由壓縮機提供的空氣而活性污泥系統(tǒng)運行與好氧狀污常3-6技術支持服務克/升運反應堆運行高度好氧顆粒污泥濃升克TSS）規(guī)范。由于這些較高的污泥濃度，空運反應堆可以操作高得多的容積負荷率可達5公斤/米研發(fā)，而傳統(tǒng)的活性污泥系統(tǒng)通常被裝載在大1-2kg/m3.d。由于年齡的硝化作用的結果，長氣升式污泥顆粒污泥反應器（氧化有-N和為硝酸鹽）4的保障，實現(xiàn)毫克值小于升可溶性N的。氣升式反應器具有集成脫硝裝置（轉(zhuǎn)換硝酸鹽氮氣）已制定和污水應用于啤酒廠和啤酒氮公斤NH-N/m4
