Carrousel氧化溝的發(fā)展由于污水處理標(biāo)準(zhǔn)中對(duì)除磷脫氮的要求越來(lái)越嚴(yán)格，Carrousel氧化溝也得到了進(jìn)一步的發(fā)展。導(dǎo)流板的材料可以用金屬或玻璃鋼，但以玻璃鋼為佳。氧化溝的曝氣設(shè)備一般為曝氣轉(zhuǎn)刷和曝氣轉(zhuǎn)盤，轉(zhuǎn)刷的浸沒深度為250~300mm，轉(zhuǎn)盤的浸沒深度為480~ 530mm。　　發(fā)生污泥上浮后應(yīng)暫停進(jìn)水，打碎或清除污泥，判明原因，調(diào)整操作。當(dāng)廢水中含表面活性物質(zhì)較多時(shí)，易預(yù)先用泡沫分離法或其他方法去除。針對(duì)污泥膨脹的起因，可采取不同對(duì)策：由缺氧、水溫高造成的，可加大曝氣量或降低進(jìn)水量以減輕負(fù)荷，或適當(dāng)降低MLSS（控制污泥回流量），使需氧量減少；如污泥負(fù)荷過(guò)高，可提高M(jìn)LSS，以調(diào)整負(fù)荷，必要時(shí)可停止進(jìn)水，悶曝一段時(shí)間；可通過(guò)投加氮肥、磷肥，調(diào)整混合液中的營(yíng)養(yǎng)物質(zhì)平衡（BOD5：N：P=100：5：1）；pH值過(guò)低，可投加石灰調(diào)節(jié)；漂白粉和液氯（%~%投加），能抑制絲狀菌繁殖，控制結(jié)合水性污泥膨脹[11]。4. Carrousel氧化溝存在的問題及解決方法　　盡管Carrousel氧化溝具有出水水質(zhì)好、抗沖擊負(fù)荷能力強(qiáng)、除磷脫氮效率高、污泥易穩(wěn)定、能耗省、便于自動(dòng)化控制等優(yōu)點(diǎn)。 Carrousel氧化溝除磷脫氮的影響因素　　影響Carrousel氧化溝除磷的因素主要是污泥齡、硝酸鹽濃度及基質(zhì)濃度。微生物的氧化過(guò)程消耗了水中溶解氧，直到DO值降為零，混合液呈缺氧狀態(tài)。3. Carrousel氧化溝的機(jī)理 Carrousel氧化溝處理污水的原理　　最初的普通Carrousel氧化溝的工藝中污水直接與回流污泥一起進(jìn)入氧化溝系統(tǒng)?！　arrousel氧化溝使用定向控制的曝氣和攪動(dòng)裝置，向混合液傳遞水平速度，從而使被攪動(dòng)的混合液在氧化溝閉合渠道內(nèi)循環(huán)流動(dòng)。本文將主要介紹Carrousel氧化溝的結(jié)構(gòu)、機(jī)理、存在的問題及其最新發(fā)展。自從1954年在荷蘭的首次投入使用以來(lái)。duit, A.
