style="text-indent:25px">測(cè)定方法：方法的選擇：氨氮檢測(cè)方法，通常有納氏比色法、苯酚-次氯酸鹽（或水楊酸-次氯酸鹽）比色法和電極法等。納氏試劑比色法具操作簡(jiǎn)便、靈敏等特點(diǎn)，水中鈣、鎂和鐵等金屬離子、硫化物、醛和酮類、顏色，以及渾濁等干擾測(cè)定，需做相應(yīng)的預(yù)處理，苯酚-次氯酸鹽比色法具靈敏、穩(wěn)定等優(yōu)點(diǎn)，干擾情況和消除方法同納氏試劑比色法。電極法通常不需要對(duì)水樣進(jìn)行預(yù)處理和具測(cè)量范圍寬等優(yōu)點(diǎn)。氨氮含量較高時(shí)，尚可采用蒸餾﹣酸滴定法。</p><p style="text-indent:25px">對(duì)人體健康的影響: 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。對(duì)生態(tài)環(huán)境的影響: 氨氮對(duì)水生物起危害作用的主要是游離氨，其毒性比銨鹽大幾十倍，并隨堿性的增強(qiáng)而增大。氨氮毒性與池水的pH值及水溫有密切關(guān)系，一般情況，pH值及水溫愈高，毒性愈強(qiáng)，對(duì)魚的危害類似于亞硝酸鹽。氨氮對(duì)水生物的危害有急性和慢性之分。慢性氨氮中毒危害為：攝食降低，生長(zhǎng)減慢，組織損傷，降低氧在組織間的輸送。魚類對(duì)水中氨氮比較敏感，當(dāng)氨氮含量高時(shí)會(huì)導(dǎo)致魚類死亡。急性氨氮中毒危害為：水生物表現(xiàn)亢奮、在水中喪失平衡、抽搐，嚴(yán)重者甚至死亡。氨氮生成黃棕色的混合物，且混合物色度和氨氮含量成正比。</p><div

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(yáng)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(guò)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(wú)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(qiáng)氧化劑將氨氮直接氧化成氮?dú)膺M(jìn)行脫除的一種方法。折點(diǎn)加氯是利用在水中的氨與氯反應(yīng)生成氮?dú)饷摪?，這種方法還可以起到殺菌作用。氨氮去除劑本產(chǎn)品為雙層包裝，重量25kg。太原氨氮菌廠家推薦</p><p

style="text-indent:25px">注意事項(xiàng)：溶液配比：建議氨氮去除劑J-201配成液體藥劑，濃度為5-15%；氨氮去除劑J-201的加藥點(diǎn)可設(shè)置在好終沉淀池、排水口；去除氨氮過(guò)程中產(chǎn)生氣泡，有一定的上浮作用，避免和PAC、PAM同時(shí)投加，降低沉降效果；氨氮去除劑避免潮濕、避免暴曬、貯存在陰涼通風(fēng)處、嚴(yán)禁與強(qiáng)酸性和氧化性物質(zhì)接觸，禁止與明火和易燃易爆品接觸。注意事項(xiàng)： 1.取一定量的含氨氮廢水，估算水中氨氮的含量； 2.加氫氧化鈉（工業(yè)級(jí)）或鹽酸（工業(yè)級(jí)）調(diào)節(jié)廢水的pH至偏堿性； 3.投加一定量的氨氮去除劑J-201，充分?jǐn)嚢瑁磻?yīng)6分鐘左右；水中的氨氮會(huì)被氨氮去除劑氧化為氮?dú)?，快速去除氨氮，不產(chǎn)生沉淀；
