沸石是一種對氨離子有很強選擇性的硅鋁酸鹽，一般作為離子交換樹脂用于去除氨氮的為斜發(fā)沸石，此法具有投資省、工藝簡單、操作較為方便的優(yōu)點，但對于高濃度的氨氮廢水，會使樹脂再生頻繁而造成操作困難，且再生液仍為高濃度氨氮廢水，需再處理。常用的離子交換系統(tǒng)有以下類型：固定;床在此系統(tǒng)中，溶液的去離子過程為二階段間歇過程。溶液通過陽樹脂床時陽離子與氫離子交換生成酸溶液，然后此溶液再通過陰樹脂床，以去除陰離子。交換能力將耗盡時，樹脂在原位再生，經(jīng)常采用向流下再生法，此法操作可靠方便，但其化學效率相對較低，容積較大，赤峰硝化菌種，聯(lián)系到樹脂用量大，有時為了適應連續(xù)流的要求，赤峰硝化菌種，還需要有儲備裝置，因而投資費用較高。氨氮一般情況，pH值及水溫愈高，赤峰硝化菌種，毒性愈強，對魚的危害類似于亞硝酸鹽。赤峰硝化菌種</p><div

style="text-indent:25px">好氧反硝化傳統(tǒng)脫氮理論認為，反硝化菌為兼性厭氧菌，其呼吸鏈在有氧條件下以氧氣為終末電子受體在缺氧條件下以硝酸根為終末電子受體。所以若進行反硝化反應，必須在缺氧環(huán)境下。近年來，好氧反硝化現(xiàn)象不斷被發(fā)現(xiàn)和報道，逐漸受到人們的關注。一些好氧反硝化菌已經(jīng)被分離出來，有些可以同時進行好氧反硝化和異養(yǎng)硝化（如Robertson等分離、篩選出的Tpantotropha.LMD82.5）。這樣就可以在同一個反應器中實現(xiàn)真正意義上的同步硝化反硝化，簡化了工藝流程，節(jié)省了能量。赤峰硝化菌種氨氮主要以氨離子或游離氨等形式存在，其能夠和納氏試劑發(fā)生反應。</p><div

style="text-indent:25px">氨氮：氨氮是指水中以游離氨（NH3）和銨離子（NH4+）形式存在的氮。動物性有機物的含氮量一般較植物性有機物為高。同時，人畜糞便中含氮有機物很不穩(wěn)定，容易分解成氨。因此，水中氨氮含量增高時指以氨或銨離子形式存在的化合氮。自然地表水體和地下水體中主要以硝酸鹽氮（NO3）為主，以游離氨（NH3）和銨離子（NH4+）形式存在的氮受污染水體的氨氮叫水合氨，也稱非離子氨。非離子氨是引起水生生物有害的主要因子，而銨離子相對基本無毒。國家標準Ⅲ類地面水，非離子氨氮的濃度≤1毫克/升。氨氮是水體中的營養(yǎng)素，可導致水富營養(yǎng)化現(xiàn)象產(chǎn)生，是水體中的主要耗氧污染物，對魚類及某些水生生物有有害。</p><p style="text-indent:25px">氨氮超標的處理方法：改善污泥負荷與污泥齡污水中的生物硝化反應屬低負荷工藝，負荷越低，硝化進行得越充分，NH3-N向NO3--N轉(zhuǎn)化的效率就越高。F/M一般在0.05～0.15kgBOD/kgMLVSS·d。負荷越低，硝化進行得越充分，NH3-N向NO3--N轉(zhuǎn)化的效率就越高。與低負荷相對應，生物硝化系統(tǒng)的SRT一般較長，因為硝化細菌世代周期較長，若生物系統(tǒng)的污泥停留時間過短，即SRT過短，污泥濃度較低時，硝化細菌就培養(yǎng)不起來，也就得不到硝化效果。SRT控制在多少，取決于溫度等因素。對于以脫氮為主要目的生物系統(tǒng)，通常SRT可取11～23d。氨氮其毒性比銨鹽大幾十倍。</p><div

style="text-indent:25px">常用的離子交換系統(tǒng)有以下幾種類型：混合床：混合床系統(tǒng)用一步法來去除溶液中的離子。溶液流過陽、陰樹脂充分混合的混合床?；旌洗驳脑偕葍蓚€單生床再生要復雜一些，因為在再生前必須將兩種樹脂分開。在水力學上可利用兩種樹脂的比重差用水力反洗使其分層。雖然混合床的化學效率較高，但它需要大量的清洗水。這對節(jié)約用水不利，另外將交換離子作為回收產(chǎn)品收集時，回收液稀，其濃縮費用也很高。移動床：移動床系統(tǒng)通過二階段過程來去除溶液中的離子。在這兩個過程中，雖然實際上工作流體處理的水是間歇的，而它的效果卻是連續(xù)的。首先溶液和陽樹脂逆向流動，陽樹脂脈動通過容器，新鮮樹脂從一端補充，用過的樹脂從另一端排出，在此過程中完成離子交換和樹脂再生。然后溶液游向流過一個與上面相似的陰樹脂移動床來完成陰離子的交換。氨氮目前遇到的內(nèi)回流導致的氨氮超標有兩方面原因:內(nèi)回流泵有電氣故障。赤峰硝化菌種</p><p style="text-indent:25px">超聲吹脫法去除氨氮是一種新型、高效的高濃度氨氮廢水處理技術。赤峰硝化菌種</p><p style="text-indent:25px">特點:是缺氧池在前，污水中的有機碳被反硝化菌所利用，可減輕其后好氧池的有機負荷，反硝化反應產(chǎn)生的堿度可以補償好氧池中進行硝化反應對堿度的需求。好氧在缺氧池之后，可以使反硝化殘留的有機污染物得到進一步去除，提高出水水質(zhì)。BOD5的去除率較高可達90～95%以上，但脫氮除磷效果稍差，脫氮效率70～80%，除磷只有20～30%。盡管如此，由于A/O工藝比較簡單，也有其突出的特點，目前仍是比較普遍采用的工藝。 2.兩段活性污泥法能有效的去除有機物和氨氮，其中第二級處于延時曝氣階段，停留時間在36小時左右，污水濃度在2g/l以下，可以不排泥或少排泥從而降低污泥處理費用.赤峰硝化菌種</p><p
