、水質(zhì)中氨氮測(cè)定的具體方法分析在水質(zhì)監(jiān)測(cè)中，氨氮是反映水質(zhì)的一項(xiàng)重要指標(biāo)，要想確保水質(zhì)監(jiān)測(cè)能夠取得積極的效果，人們就需要準(zhǔn)確測(cè)量氨氮含量。現(xiàn)階段，水質(zhì)監(jiān)測(cè)人員要想有效測(cè)定氨氮，可以運(yùn)用以下方式。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(yīng)，生成黃棕色的混合物，且混合物色度和氨氮含量成正比，人們可以采取目視比色法與分光光度法進(jìn)行測(cè)定。其中，在運(yùn)用目視比色法進(jìn)行測(cè)定時(shí)，0.02 mg/L 為較低檢出濃度，上限濃度為2 mg/L；運(yùn)用分光光度法進(jìn)行測(cè)定時(shí)，0.05 mg/L 為較低檢出濃度，上限濃度則為 2 mg/L?！端|(zhì)氨氮的測(cè)定納氏試劑分光光度法》將該方式定為標(biāo)準(zhǔn)分析方法。納氏試劑分光光度法運(yùn)用好為較廣，其主要原理為 HgI2 與 KI 的堿性溶液和氨反應(yīng)而生成淡紅棕色膠態(tài)化合物，且色度和氨氮含量成正比。該方法一般能夠在波長(zhǎng) 410 ～ 425 nm 內(nèi)測(cè)定其吸光度，但水樣通常需經(jīng)過(guò)前處理來(lái)排除各類干擾比色測(cè)定的因素。開(kāi)封硝化細(xì)菌廠家氨氮污水的處理技術(shù)都有各自的優(yōu)勢(shì)與不足。</p><div

style="text-indent:25px">生物法：生物法機(jī)理——生物硝化和反硝化機(jī)理在污水的生物脫氮處理過(guò)程中，首先在好氧條件下，通過(guò)好氧硝化菌的作用，將污水中的氨氮氧化為亞硝酸鹽或硝酸鹽 ;然后在缺氧條件下，利用反硝化菌(脫氮菌)將亞硝酸鹽和硝酸鹽還原為氮?dú)舛鴱奈鬯幸莩?。因而，污水的生物脫氮包括硝化和反硝化兩個(gè)階段。硝化反應(yīng)是將氨氮轉(zhuǎn)化為硝酸鹽的過(guò)程，包括兩個(gè)基本反應(yīng)步驟 : 由亞硝酸菌參與的將氨氮轉(zhuǎn)化為亞硝酸鹽的反應(yīng);由硝酸菌參與的將亞硝酸鹽轉(zhuǎn)化為硝酸鹽的反應(yīng)。在缺氧條件下，由于兼性脫氮菌(反硝化菌) 的作用，將硝化過(guò)程中產(chǎn)生的硝酸鹽或亞硝酸鹽還原成N2的過(guò)程，稱為反硝化。反硝化過(guò)程中的電子供體是各種各樣的有機(jī)底物(碳源) 。生物脫氮法可去除多種含氮化合物，總氮去除率可達(dá)70%—95%，二次污染小且比較經(jīng)濟(jì)，因此在國(guó)內(nèi)外運(yùn)用好多。但缺點(diǎn)是占地面積大，低溫時(shí)效率低。</p><p style="text-indent:25px">高濃度氨氮廢水簡(jiǎn)介：氨氮是指水中以游離氨（NH3）和銨離子（NH4+）形式存在的氮。氨氮是水體中的營(yíng)養(yǎng)素，可導(dǎo)致水富營(yíng)養(yǎng)化現(xiàn)象產(chǎn)生，是水體中的主要耗氧污染物，對(duì)魚類及某些水生生物有有害。水中的氨氮可以在一定條件下轉(zhuǎn)化成亞硝酸鹽，如果長(zhǎng)期飲用，水中的亞硝酸鹽將和蛋白質(zhì)結(jié)合形成亞硝胺，這是一種強(qiáng)致病物質(zhì)，對(duì)人體健康極為不利。高濃度氨氮廢水主要來(lái)源于鋼鐵、煉油、化肥、無(wú)機(jī)化工、鐵合金、玻璃制造、肉類加工和飼料生產(chǎn)等工業(yè)生產(chǎn)過(guò)程。有些工業(yè)廢水如皮革加工等新鮮廢水中氨氮初始哈按量并不高，但由于廢水中有機(jī)氮的脫氨基反應(yīng)致使氨氮升高。目前常用的是氨氣敏電極法和納氏試劑比色法。氨氮比較敏感，當(dāng)氨氮含量高時(shí)會(huì)導(dǎo)致魚類死亡。</p><div

折點(diǎn)氯化法是將氯氣通入廢水中達(dá)到某一點(diǎn)，在該點(diǎn)時(shí)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(guò)該點(diǎn)時(shí)，水中的游離氯就會(huì)增多。因此，該點(diǎn)稱為折點(diǎn)。該狀態(tài)下的氯化稱為折點(diǎn)氯化。折點(diǎn)氯化法除氨的機(jī)理為氯氣與氨反應(yīng)生成無(wú)害的氮?dú)?，N2 逸入大氣，使反應(yīng)源源不斷向右進(jìn)行。加氯比例:M（Cl2）與M（NH3-N）之比為8 :l - 10 :1 。當(dāng)氨氮濃度小于20 mg/ L 時(shí)，脫氮率大于90 % ，pH 影響較大，pH 高時(shí)產(chǎn)生NO3- ，低時(shí)產(chǎn)生NCl3 ，將消耗氯，通常控制pH在6-8。此法用于廢水的深度處理，脫氮率高、設(shè)備投資少、反應(yīng)迅速完全，并有消毒作用。但液氯安全使用和貯存要求高，對(duì)pH要求也很高，產(chǎn)生的水需加堿中和，因此處理成本高。另外副產(chǎn)物氯胺和氯代有機(jī)物會(huì)造成二次污染。在水質(zhì)監(jiān)測(cè)中，氨氮是反映水質(zhì)的一項(xiàng)重要指標(biāo)。開(kāi)封氨氮去除菌</p><p
