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，成都硝化菌種哪家好，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，成都硝化菌種哪家好，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，成都硝化菌種哪家好、抽搐，嚴(yán)重者甚至死亡。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。成都硝化菌種哪家好</p><div

目前遇到的內(nèi)回流導(dǎo)致的氨氮超標(biāo)有兩方面原因:內(nèi)回流泵有電氣故障（現(xiàn)場(chǎng)跳停扔有運(yùn)行信號(hào)）、機(jī)械故障（葉輪脫落）和人為原因（內(nèi)回流泵未試正反轉(zhuǎn)，現(xiàn)場(chǎng)為反轉(zhuǎn)狀態(tài)）。分析：內(nèi)回流導(dǎo)致的氨氮超標(biāo)也可以歸到有機(jī)物沖擊中，因?yàn)闆]有硝化液的回流，導(dǎo)致A池中只有少量外回流攜帶的硝態(tài)氮，總體成厭氧環(huán)境，碳源只會(huì)水解酸化而不會(huì)完全代謝成二氧化碳逸出。所以大量有機(jī)物進(jìn)入曝氣池，導(dǎo)致了氨氮的升高。解決辦法：內(nèi)回流的問題很好發(fā)現(xiàn)，可以通過數(shù)據(jù)及趨勢(shì)來判斷是否是內(nèi)回流導(dǎo)致的問題：初期O池出口硝態(tài)氮升高，A池硝態(tài)氮降低直至0，PH降低等，所以解決辦法分三種情況： 1、及時(shí)發(fā)現(xiàn)問題，檢修內(nèi)回流泵就可以了。 2、內(nèi)回流已經(jīng)導(dǎo)致氨氮升高，檢修內(nèi)回流泵，停止或者減少進(jìn)水進(jìn)行悶爆。 3、硝化系統(tǒng)已經(jīng)崩潰，停止進(jìn)水悶爆，如果有條件、情況比較緊迫可以投加相似脫氮系統(tǒng)的生化污泥，加快系統(tǒng)恢復(fù)。成都硝化菌種哪家好利用反硝化菌(脫氮菌)將亞硝酸鹽和硝酸鹽還原為氮?dú)舛鴱奈鬯幸莩觥?/p><div style="width:100%;text-align: center;"><img

傳統(tǒng)和新開發(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。 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(jī)物水解為有機(jī)酸，使大分子有機(jī)物分解為小分子有機(jī)物，不溶性的有機(jī)物轉(zhuǎn)化成可溶性有機(jī)物，當(dāng)這些經(jīng)缺氧水解的產(chǎn)物進(jìn)入好氧池進(jìn)行好氧處理時(shí)，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(jìn)行氨化（有機(jī)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(shí)現(xiàn)污水無害化處理。</p><p

1/10。在進(jìn)水COD 800～4500mg/L、氨氮 100～650mg/L、揮發(fā)酚低于1000mg/L、**物低于70mg/L、BOD5/COD為0.1～0.3的情況下，經(jīng)處理后出水COD低于100mg/L、氨氮低于15mg/L。氨氮是水體中的主要耗氧污染物。</p><div style="width:100%;text-align: center;"><img
