①氨氮去除劑A2的投加，氨氮去除劑A2是一種含有特殊架狀結(jié)構(gòu)的高分子無(wú)機(jī)化合物；氨氮去除劑A2是專門針對(duì)生化難以處理的廢水所研發(fā)的功能劑，它適用于各行業(yè)污水氨氮超標(biāo)治理；無(wú)需生化，在物化階段達(dá)到去除氨氮的目的，反應(yīng)速度快，只需5-6min，去除率可達(dá)95%以上；同時(shí)兼具輔助降低COD和脫色的作用，用于生活污水、電鍍、線路板、化工等廢水。 ② 吹脫法，石家莊氨氮降解菌種，吹脫法的基本原理是氣液相平衡和傳質(zhì)速度理論。將氨氮廢水PH調(diào)節(jié)至堿性，此時(shí)銨離子轉(zhuǎn)化為氨分子，石家莊氨氮降解菌種，石家莊氨氮降解菌種，再向水中通入氣體，使其與液體充分接觸，廢水中溶解的氣體和揮發(fā)性氨分子穿過(guò)氣液界面，轉(zhuǎn)至氣相，從而達(dá)到去除氨氮的目的。常用空氣或水蒸氣作載氣，前者稱為空氣吹脫，后者稱為蒸汽吹脫。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。石家莊氨氮降解菌種</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(dòng)物性有機(jī)物的含氮量一般較植物性有機(jī)物為高。同時(shí)，人畜糞便中含氮有機(jī)物很不穩(wěn)定，容易分解成氨。因此，水中氨氮含量增高時(shí)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(duì)基本無(wú)毒。國(guó)家標(biāo)準(zhǔn)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(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。實(shí)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。石家莊氨氮降解菌種</p><p

style="text-indent:25px">常見(jiàn)的高氨氮廢水處理工藝：高濃度氨氮廢水處理方法通常有物化法、生物脫氮法、生化聯(lián)合法等，其中物化法主要分為吹脫法、沸石脫氨法、膜分離技術(shù)、MAP沉淀法、化學(xué)氧化法；傳統(tǒng)和新開(kāi)發(fā)的脫氮工藝有A/O，兩段活性污泥法、強(qiáng)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；物化方法在處理高濃度氨氮廢水時(shí)不會(huì)因?yàn)榘钡獫舛冗^(guò)高而受到限制，但是不能將氨氮濃度降到足夠低（如100mg/L以下）。而生物脫氮會(huì)因?yàn)楦邼舛扔坞x氨或者亞硝酸鹽氮而受到壓抑。實(shí)際應(yīng)用中采用生化聯(lián)合的方法，在生物處理前先對(duì)含高濃度氨氮的廢水進(jìn)行物化處理。石家莊氨氮降解菌種</p></p><br
