style="text-indent:25px">內(nèi)回流導(dǎo)致的氨氮超標(biāo) 目前遇到的內(nèi)回流導(dǎo)致的氨氮超標(biāo)有兩方面原因:內(nèi)回流泵有電氣故障（現(xiàn)場跳停扔有運行信號）、機械故障（葉輪脫落）和人為原因（內(nèi)回流泵未試正反轉(zhuǎn)，現(xiàn)場為反轉(zhuǎn)狀態(tài)）。分析：內(nèi)回流導(dǎo)致的氨氮超標(biāo)也可以歸到有機物沖擊中，因為沒有硝化液的回流，導(dǎo)致A池中只有少量外回流攜帶的硝態(tài)氮，總體成厭氧環(huán)境，碳源只會水解酸化而不會完全代謝成二氧化碳逸出，拉薩硝化菌種哪家好。所以大量有機物進(jìn)入曝氣池，拉薩硝化菌種哪家好，導(dǎo)致了氨氮的升高。解決辦法：內(nèi)回流的問題很好發(fā)現(xiàn)，可以通過數(shù)據(jù)及趨勢來判斷是否是內(nèi)回流導(dǎo)致的問題：初期O池出口硝態(tài)氮升高，A池硝態(tài)氮降低直至0，PH降低等，所以解決辦法分三種情況： 1、及時發(fā)現(xiàn)問題，檢修內(nèi)回流泵就可以了。 2、內(nèi)回流已經(jīng)導(dǎo)致氨氮升高，檢修內(nèi)回流泵，停止或者減少進(jìn)水進(jìn)行悶爆。 3、硝化系統(tǒng)已經(jīng)崩潰，停止進(jìn)水悶爆，如果有條件、情況比較緊迫可以投加相似脫氮系統(tǒng)的生化污泥，加快系統(tǒng)恢復(fù)。氨氮導(dǎo)致來水氨氮突然升高，拉薩硝化菌種哪家好，脫氮系統(tǒng)崩潰，出水氨氮超標(biāo)。拉薩硝化菌種哪家好</p><div style="width:100%;text-align:

style="text-indent:25px">氨氮超標(biāo)的主要原因及解決辦法：有機物導(dǎo)致的氨氮超標(biāo)：超標(biāo)原因：我運營過CN比小于3的高氨氮污水，因脫氮工藝要求CN比在4~6，所以需要投加碳源來提高反硝化的完全性。當(dāng)時投加的碳源是甲醇，因為某些原因甲醇儲罐出口閥門脫落，大量甲醇進(jìn)入A池，導(dǎo)致曝氣池泡沫很多，出水COD，氨氮飆升，系統(tǒng)崩潰。原因分析：大量碳源進(jìn)入A池，反硝化利用不了，進(jìn)入曝氣池，因為底物充足，異養(yǎng)菌有氧代謝，大量消耗氧氣和微量元素，因為硝化細(xì)菌是自養(yǎng)菌，代謝能力差，氧氣被爭奪，形成不了優(yōu)勢菌種，所以硝化反應(yīng)受限制，氨氮升高。解決辦法： 1、立即停止進(jìn)水進(jìn)行悶爆、內(nèi)外回流連續(xù)開啟。 2、停止壓泥保證污泥濃度。 3、如果有機物已經(jīng)引起非絲狀菌膨脹可以投加PAC來增加污泥絮性、投加消泡劑來消除沖擊泡沫。拉薩硝化菌種哪家好水樣帶色或渾濁以及含其它一些干擾物質(zhì)，影響氨氮的測定。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">好氧反硝化傳統(tǒng)脫氮理論認(rèn)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(jìn)行反硝化反應(yīng)，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(guān)注。一些好氧反硝化菌已經(jīng)被分離出來，有些可以同時進(jìn)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(yīng)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。 </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(fù)荷，反硝化反應(yīng)產(chǎn)生的堿度可以補償好氧池中進(jìn)行硝化反應(yīng)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(jìn)一步去除，提高出水水質(zhì)。BOD5的去除率較高可達(dá)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.實現(xiàn)短程硝化反硝化生物脫氮技術(shù)的關(guān)鍵就是將硝化控制在亞硝酸階段，阻止亞硝酸鹽的進(jìn)一步氧化。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">常用的廢水中氨氮的去除物理化學(xué)方法有以下幾種： 1.吹脫法：在堿性條件下，利用氨氮的氣相濃度和液相濃度之間的氣液平衡關(guān)系進(jìn)行分離的一種方法。一般認(rèn)為吹脫效率與溫度、PH、氣液比有關(guān)。 2.沸石脫氮法：利用沸石中的陽離子與廢水中的NH4＋進(jìn)行交換以達(dá)到脫氮目的。沸石一般被用于處理低濃度含氨廢水或含微量重金屬的廢水。 3.膜分離技術(shù)：利用膜的選擇透過性進(jìn)行氨氮脫除的一種方法，這種方法操作方便，氨氮回收率高，無二次污染。 4.MAP沉淀法：是向含有高濃度氨氮的廢水中投加磷鹽和鎂鹽，除去廢水中的氨氮。 5.化學(xué)氧化法：是利用強氧化劑將氨氮直接氧化成氮氣進(jìn)行脫除的一種方法。折點加氯是利用在水中的氨與氯反應(yīng)生成氮氣脫氨，這種方法還可以起到殺菌作用。城市污水、中低氨氮濃度工業(yè)廢水中氨氮的去除，由于生物法因工藝簡單。拉薩硝化細(xì)菌價格</p><p

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(xué)效率相對較低，容積較大，聯(lián)系到樹脂用量大，有時為了適應(yīng)連續(xù)流的要求，還需要有儲備裝置，因而投資費用較高。拉薩硝化菌種哪家好</p></p><br
