折點氯化法是將氯氣通入廢水中達到某一點，在該點時水中游離氯含量較低，而氨的濃度降為零。當(dāng)氯氣通入量超過該點時，水中的游離氯就會增多。因此，該點稱為折點。該狀態(tài)下的氯化稱為折點氯化。折點氯化法除氨的機理為氯氣與氨反應(yīng)生成無害的氮氣，N2 逸入大氣，使反應(yīng)源源不斷向右進行。加氯比例:M（Cl2）與M（NH3-N）之比為8 :l - 10 :1

1.方法原理碘化汞和碘化鉀的堿性溶液與氨反應(yīng)生成淡紅棕色膠態(tài)化合物，此顏色在較寬的波長范圍內(nèi)具強烈吸收。通常測量用波長在410—425nm范圍。 2.干擾及消除脂肪胺、芳香胺、醛類、**、醇類和有機氯胺類等有機化合物，以及鐵、錳、鎂、硫等無機離子，因產(chǎn)生異色或渾濁而引起干擾，水中顏色和渾濁亦影響比色。為此，須經(jīng)絮凝沉淀過濾或蒸餾預(yù)處理，易揮發(fā)的還原性干擾物質(zhì)，還可在酸性條件下加熱除去。對金屬離子的干擾，可加入適量的掩蔽劑加以消除。 3.方法適用范圍本法較低檢出濃度為0.025mol/L（光度法），測定上限為2mg/L。采用目視比色法，較低檢出濃度為0.02mg/L。水樣作適當(dāng)?shù)念A(yù)處理后，本法可適用于地表水、地下水、工業(yè)廢水和生活污水。</p><p style="text-indent:25px">生物脫氮法: 傳統(tǒng)和新開發(fā)的脫氮工藝有A/O，兩段活性污泥法、強氧化好氧生物處理、短程硝化反硝化、超聲吹脫處理氨氮法方法等。 1.A/O工藝將前段缺氧段和后段好氧段串聯(lián)在一起，A段DO不大于0.2mg/L，O段DO=2～4mg/L。在缺氧段異養(yǎng)菌將污水中的淀粉、纖維、碳水化合物等懸浮污染物和可溶性有機物水解為有機酸，使大分子有機物分解為小分子有機物，不溶性的有機物轉(zhuǎn)化成可溶性有機物，當(dāng)這些經(jīng)缺氧水解的產(chǎn)物進入好氧池進行好氧處理時，提高污水的可生化性，提高氧的效率；在缺氧段異養(yǎng)菌將蛋白質(zhì)、脂肪等污染物進行氨化（有機鏈上的N或氨基酸中的氨基）游離出氨（NH3、NH4+），在充足供氧條件下，自養(yǎng)菌的硝化作用將NH3-N（NH4+）氧化為NO3-，通過回流控制返回至A池，在缺氧條件下，異氧菌的反硝化作用將NO3-還原為分子態(tài)氮（N2）完成C、N、O在生態(tài)中的循環(huán)，實現(xiàn)污水無害化處理。氨氮導(dǎo)致來水氨氮突然升高，脫氮系統(tǒng)崩潰，出水氨氮超標(biāo)。</p><div

style="text-indent:25px">短程硝化反硝化生物硝化反硝化是應(yīng)用好較廣的脫氮方式，是去除水中氨氮的一種較為經(jīng)濟的方法，其原理就是模擬自然生態(tài)環(huán)境中氮的循環(huán)，利用硝化菌和反硝化菌的聯(lián)合作用，將水中氨氮轉(zhuǎn)化為氮氣以達到脫氮目的。由于氨氮氧化過程中需要大量的氧氣，曝氣費用成為這種脫氮方式的主要開支。短程硝化反硝化是將氨氮氧化控制在亞硝化階段，然后進行反硝化，省去了傳統(tǒng)生物脫氮中由亞硝酸鹽氧化成硝酸鹽，再還原成亞硝酸鹽兩個環(huán)節(jié)（即將氨氮氧化至亞硝酸鹽氮即進行反硝化）。該技術(shù)具有很大的優(yōu)勢：①節(jié)省25%氧供應(yīng)量，降低能耗；②減少40%的碳源，在C/N較低的情況下實現(xiàn)反硝化脫氮；③縮短反應(yīng)歷程，節(jié)省50%的反硝化池容積；④降低污泥產(chǎn)量，硝化過程可少產(chǎn)污泥33%~35%左右，反硝化階段少產(chǎn)污泥55%左右。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，阻止亞硝酸鹽的進一步氧化。吉林氨氮菌廠家</p></p><br
