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(zhuān)門(mén)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(xiàn)路板、化工等廢水。 ② 吹脫法，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，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(chēng)為空氣吹脫，后者稱(chēng)為蒸汽吹脫。氨吹脫、汽提工藝具有流程簡(jiǎn)單、處理效果穩(wěn)定、基建費(fèi)和運(yùn)行費(fèi)較低等優(yōu)點(diǎn)。</p><div

2.兩段活性污泥法能有效的去除有機(jī)物和氨氮，其中第二級(jí)處于延時(shí)曝氣階段，停留時(shí)間在36小時(shí)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(fèi)用.氨氮氧化是指在厭氧條件下氨氮以亞硝酸鹽為電子受體直接被氧化成氮?dú)獾倪^(guò)程。張家口硝化菌種哪個(gè)牌子好</p><p
