57、生工程研究所研制成功的。自從1954年在荷蘭的首次投入使用以來。由于其出水水質(zhì)好、運行穩(wěn)定、管理方便等技術(shù)特點，已經(jīng)在國內(nèi)外廣泛的應(yīng)用于生活污水和工業(yè)污水的治理。</p><p>　　目前應(yīng)用較為廣泛的氧化溝類型包括：帕斯韋爾氧化溝、卡魯塞爾氧化溝 、奧貝爾氧化溝、T型氧化溝（三溝式氧化溝）、DE型氧化溝和一體化氧化溝。這些氧化溝由于在結(jié)構(gòu)和運行上存在差異，因此各具特點。本文將主要介紹卡羅塞爾氧化溝的結(jié)構(gòu)、機理、

58、存在的問題及其最新發(fā)展。</p><p>　　2.卡羅塞爾氧化溝的結(jié)構(gòu)</p><p>　　卡羅塞爾氧化溝是1967年由荷蘭的DHV公司開發(fā)研制。在原卡羅塞爾氧化溝的基礎(chǔ)上DHV公司和其在美國的專利特許公司EIMCO又發(fā)明了卡羅塞爾2000系統(tǒng)，實現(xiàn)了更高要求的生物脫氮和除磷功能。至今世界上已有850多座卡羅塞爾氧化溝和卡羅塞爾 2000系統(tǒng)正在運行。</p><p&g

59、t;　　卡羅塞爾氧化溝使用定向控制的曝氣和攪動裝置，向混合液傳遞水平速度，從而使被攪動的混合液在氧化溝閉合渠道內(nèi)循環(huán)流動。因此氧化溝具有特殊的水力學(xué)流態(tài)，既有完全混合式反應(yīng)器的特點，又有推流式反應(yīng)器的特點，溝內(nèi)存在明顯的溶解氧濃度梯度。氧化溝斷面為矩形或梯形，平面形狀多為橢圓形，溝內(nèi)水深一般為2.5～4.5ｍ，寬深比為2:1，亦有水深達7m的，溝中水流平均速度為0.3m/s。氧化溝曝氣混合設(shè)備有表面曝氣機、曝氣轉(zhuǎn)刷或轉(zhuǎn)盤、射流曝氣器、導(dǎo)

60、管式曝氣器和提升管式曝氣機等，近年來配合使用的還有水下推動器。</p><p>　　3. 卡羅塞爾氧化溝的機理</p><p>　　3.1 卡羅塞爾氧化溝處理污水的原理</p><p>　　最初的普通卡羅塞爾氧化溝的工藝中污水直接與回流污泥一起進入氧化溝系統(tǒng)。表面曝氣機使混合液中溶解氧DO的濃度增加到大約2～3mg/L。在這種充分摻氧的條件下，微生物得到足夠的溶解氧

61、來去除BOD；同時，氨也被氧化成硝酸鹽和亞硝酸鹽，此時，混合液處于有氧狀態(tài)。在曝氣機下游，水流由曝氣區(qū)的湍流狀態(tài)變成之后的平流狀態(tài)，水流維持在最小流速，保證活性污泥處于懸浮狀態(tài)（平均流速>0.3m/s）。微生物的氧化過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)。經(jīng)過缺氧區(qū)的反硝化作用，混合液進入有氧區(qū)，完成一次循環(huán)。該系統(tǒng)中，BOD降解是一個連續(xù)過程，硝化作用和反硝化作用發(fā)生在同一池中。由于結(jié)構(gòu)的限制，這種氧化溝雖然可

62、以有效的去處BOD，但除磷脫氮的能力有限。</p><p>　　3.2 卡羅塞爾氧化溝除磷脫氮的影響因素</p><p>　　影響卡羅塞爾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。研究表明，當(dāng)總污泥齡為8~10d時活性污泥中的最大磷含量為其干污泥量的4%，為異養(yǎng)菌體質(zhì)量的11%，但當(dāng)污泥齡超過15d時污泥中最大含磷量明顯下降，反而達不到最大除磷效果。因此，一味延長污泥齡（例如20

63、d、25d、30d）是沒有必要的，宜在8~15d范圍內(nèi)選用。同時，高硝酸鹽濃度和低基質(zhì)濃度不利于除磷過程。</p><p>　　4. 卡羅塞爾氧化溝存在的問題及解決方法</p><p>　　盡管卡羅塞爾氧化溝具有出水水質(zhì)好、抗沖擊負荷能力強、除磷脫氮效率高、污泥易穩(wěn)定、能耗省、便于自動化控制等優(yōu)點。但是，在實際的運行過程中，仍存在一系列的問題。</p><p>　　

64、4.1 污泥膨脹問題</p><p>　　當(dāng)廢水中的碳水化合物較多，N、P含量不平衡，pH值偏低，氧化溝中污泥負荷過高，溶解氧濃度不足，排泥不暢等易引發(fā)絲狀菌性污泥膨脹；非絲狀菌性污泥膨脹主要發(fā)生在廢水水溫較低而污泥負荷較高時。微生物的負荷高，細菌吸取了大量營養(yǎng)物質(zhì)，由于溫度低，代謝速度較慢，積貯起大量高粘性的多糖類物質(zhì)，使活性污泥的表面附著水大大增加，SVI值很高，形成污泥膨脹。</p><

65、p>　　針對污泥膨脹的起因，可采取不同對策：由缺氧、水溫高造成的，可加大曝氣量或降低進水量以減輕負荷，或適當(dāng)降低MLSS（控制污泥回流量），使需氧量減少；如污泥負荷過高，可提高MLSS，以調(diào)整負荷，必要時可停止進水，悶曝一段時間；可通過投加氮肥、磷肥，調(diào)整混合液中的營養(yǎng)物質(zhì)平衡（BOD5：N：P=100：5：1）；pH值過低，可投加石灰調(diào)節(jié)；漂白粉和液氯（按干污泥的0.3%~0.6%投加），能抑制絲狀菌繁殖，控制結(jié)合水性污泥膨脹。

66、</p><p><b>　　4.2 泡沫問題</b></p><p>　　由于進水中帶有大量油脂，處理系統(tǒng)不能完全有效地將其除去，部分油脂富集于污泥中，經(jīng)轉(zhuǎn)刷充氧攪拌，產(chǎn)生大量泡沫；泥齡偏長，污泥老化，也易產(chǎn)生泡沫。用表面噴淋水或除沫劑去除泡沫，常用除沫劑有機油、煤油、硅油，投量為0.5~1.5mg/L。通過增加曝氣池污泥濃度或適當(dāng)減小曝氣量，也能有效控制泡沫產(chǎn)生。

67、當(dāng)廢水中含表面活性物質(zhì)較多時，易預(yù)先用泡沫分離法或其他方法去除。另外也可考慮增設(shè)一套除油裝置。但最重要的是要強水資源管理理，減少含油過高廢水及其它有毒廢水的進入。</p><p>　　4.3 污泥上浮問題</p><p>　　當(dāng)廢水中含油量過大，整個系統(tǒng)泥質(zhì)變輕，在操作過程中不能很好控制其在二沉池的停留時間，易造成缺氧，產(chǎn)生腐化污泥上??；當(dāng)曝氣時間過長，在池中發(fā)生高度硝化作用，使硝酸鹽濃度

68、高，在二沉池易發(fā)生反硝化作用，產(chǎn)生氮氣，使污泥上??；另外，廢水中含油量過大，污泥可能挾油上浮。</p><p>　　發(fā)生污泥上浮后應(yīng)暫停進水，打碎或清除污泥，判明原因，調(diào)整操作。污泥沉降性差，可投加混凝劑或惰性物質(zhì)，改善沉淀性；如進水負荷大應(yīng)減小進水量或加大回流量；如污泥顆粒細小可降低曝氣機轉(zhuǎn)速；如發(fā)現(xiàn)反硝化，應(yīng)減小曝氣量，增大回流或排泥量；如發(fā)現(xiàn)污泥腐化，應(yīng)加大曝氣量，清除積泥，并設(shè)法改善池內(nèi)水力條件。<

69、/p><p>　　4.4 流速不均及污泥沉積問題</p><p>　　在卡羅塞爾氧化溝中，為了獲得其獨特的混合和處理效果，混合液必須以一定的流速在溝內(nèi)循環(huán)流動。一般認為，最低流速應(yīng)為0.15m/s，不發(fā)生沉積的平均流速應(yīng)達到0.3~0.5m/s。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。與氧化溝水深（3.0~3.6m）相

70、比，轉(zhuǎn)刷只占了水深的1/10~1/12，轉(zhuǎn)盤也只占了1/6~1/7，因此造成氧化溝上部流速較大（約為0.8~1.2m，甚至更大），而底部流速很?。ㄌ貏e是在水深的2/3或3/4以下，混合液幾乎沒有流速），致使溝底大量積泥（有時積泥厚度達1.0m），大大減少了氧化溝的有效容積，降低了處理效果，影響了出水水質(zhì)。</p><p>　　加裝上、下游導(dǎo)流板是改善流速分布、提高充氧能力的有效方法和最方便的措施。上游導(dǎo)流板安裝在

71、距轉(zhuǎn)盤（轉(zhuǎn)刷）軸心4.0處（上游），導(dǎo)流板高度為水深的1/5~1/6，并垂直于水面安裝；下游導(dǎo)流板安裝在距轉(zhuǎn)盤（轉(zhuǎn)刷）軸心3.0m處。導(dǎo)流板的材料可以用金屬或玻璃鋼，但以玻璃鋼為佳。導(dǎo)流板與其他改善措施相比，不僅不會增加動力消耗和運轉(zhuǎn)成本，而且還能夠較大幅度地提高充氧能力和理論動力效率。</p><p>　　另外，通過在曝氣機上游設(shè)置水下推動器也可以對曝氣轉(zhuǎn)刷底部低速區(qū)的混合液循環(huán)流動起到積極推動作用，從而解決氧

72、化溝底部流速低、污泥沉積的問題。設(shè)置水下推動器專門用于推動混合液可以使氧化溝的運行方式更加靈活，這對于節(jié)約能源、提高效率具有十分重要的意義。</p><p>　　5. 卡羅塞爾氧化溝的發(fā)展</p><p>　　由于污水處理標準中對除磷脫氮的要求越來越嚴格，卡羅塞爾氧化溝也得到了進一步的發(fā)展。目前，研究及應(yīng)用較多的包括以下兩種類型：微孔曝氣型卡羅塞爾2000系統(tǒng)、卡羅塞爾3000系統(tǒng)。<

73、;/p><p>　　5.1 微孔曝氣型卡羅塞爾2000系統(tǒng)</p><p>　　微孔曝氣型卡羅塞爾2000系統(tǒng)采用微孔曝氣（供氧設(shè)備為鼓風(fēng)機），微孔曝氣器可產(chǎn)生大量直徑為1mm左右的微小氣泡，這大大提高了氣泡的表面積，使得在池容積一定的情況下氧轉(zhuǎn)移總量增大（如池深增加則其傳質(zhì)效率將更高）。根據(jù)目前鼓風(fēng)機生產(chǎn)廠家的技術(shù)能力，池的有效水深最大可8m，因此可根據(jù)不同的工藝要求選取合適的水深。傳統(tǒng)氧化

74、溝的推流是利用轉(zhuǎn)刷、轉(zhuǎn)碟或倒傘型表曝機實現(xiàn)的，其設(shè)備利用率低、動力消耗大。微孔曝氣型卡羅塞爾2000系統(tǒng)則采用了水下推流的方式，即把潛水推進器葉輪產(chǎn)生的推動力直接作用于水體，在起推流作用的同時又可有效防止污泥的沉降。因而，采用潛水推進器既降低了動力消耗，又使泥水得到了充分地混合。</p><p>　　5.2 卡羅塞爾3000系統(tǒng)</p><p>　　卡羅塞3000系統(tǒng)是在卡羅塞爾2000系
