The Carrousel oxidizes the ditch divideds by the phosphorus takes off the nitrogenous influence factor. Affecting the Carrousel oxidizes the ditch divideds by the phosphoric factor is dirty mire, nitrate density and quality densities research expresses, being total and dirty mire as 11% that a hour biggest phosphorus 4% with deal is its fuck dirty mire deal within live and dirty mire, keep for the the germ physical endowment measures, but when dirty mire over 15 d hour dirty mire the Inside is biggesttocontain theobviousdescentindealIn phosphorus,canning not reach the biggest divideding by the result of phosphorus on the , prolong persistently the dirty mire (for example 20ds,25ds,30ds) is to have no necessary, proper choose to use within the scope of 8~ 15 the same time, high nitrate density with low quality density disadvantage in divided by the process of phosphorus . 4. The Carrousel oxidizes problem and solution methods of the ditch esse. Though the Carrousel oxidizes the ditch has a water fluid matter good, the antipounds at the burthen ability strong, divided by the phosphorus take off the nitrogen efficiency. But, in physically of movement process, still exstts a series of problem. Dirty mire inflation problem When discard the aquatic carbohydrate more, the N, P contains the unbalance of deal, the pH value is low, oxidizing the dirty mire in inside in ditch carries high, fuse the oxygen density the shortage, line up the mire not etc. causes easily dirty mire in germ in form in silk inflatlon。為搞清聚磷菌除磷的生化機理，已開始用分子診斷技術獲取聚磷菌的遺傳信息。的容積負荷為2g246。由于處理效率低、速度慢、且甲烷菌對環(huán)境要求嚴格不易控制等缺點，厭氧生物處理法長期以來一般僅用于污泥處理，它的主要工藝是化糞池、消化池等。流程。3.本工藝50年代初期發(fā)展形成，因其構造簡單，易于管理，很快得到推廣，且不斷創(chuàng)新，有發(fā)展前景和競爭力，當前可謂熱門工藝。有的城市污水處理的出水不排入湖泊，利用大水體深水排放或灌溉農田，可將脫氮除此法集進水、曝氣、沉淀、出水在一座池子中完成，常由四個或三個池子構成一組，輪流運轉，一池一池地間歇運行，故稱序批式活性污泥法。處理城鎮(zhèn)污水水質為：CODCr：300mg/L ，BOD5 ：140mg/L ， SS：200mg/L ， NH4+N：25mg/L，TP ：4mg/L.要求達到的出水水質：CODCr 163。AB法(Adsorption—Biooxidation)但因每個池子都需要設曝氣和輸配水系統(tǒng)，采用潷水器及控制系統(tǒng)，間歇排水水頭損失大，池容的利用率不理想，因此，一般來說并不太適用于大規(guī)模的城市污水處理廠普通曝氣法及其變法。奧式(Orbal)簡稱同心圓式，應用上多為橢圓形的三環(huán)道組成，三個環(huán)道用不同的DO(如外環(huán)為0，中環(huán)為1，內環(huán)為2)，有利于脫氮除磷。無論是好氧生物處理技術，還是厭氧生物處理技術都引起了研究人員的極大興趣。(2)還有人為地固定微生物包埋固定化法，厭氧生物處理法目前的發(fā)展趨勢是和其它生物處理方法聯(lián)用，分子診斷技術的大量應用，活性污泥微生物基因庫的建立，在此基礎上用基因技術培育具有高效活性的污泥菌種，進一步提高處理效果，是未來發(fā)展的方向。The mire is partial to long, the dirty mire is aging, and also easy creation topourthewaterordivided bywiththesurfacetheof do away with the foam, in mon use divided by the an organism oil, kerosene, the oil of stncon, throw deal as ~ mgsl to increase dirty mire in pond in spirit in density or adequacies let up the tolerance of ,also can control the foam creation contain the live materia! in surface in the waste water more, separate with the foam easily and in advance method or other methods do away can consider to increase to establish a set of dlvideding by the oil device enhance most importantly the headwaters manage, reducing to contain the oil over the high waste water and other poisonous waste water of into[llJ.

Carrousel氧化溝的發(fā)展由于污水處理標準中對除磷脫氮的要求越來越嚴格，Carrousel氧化溝也得到了進一步的發(fā)展。當廢水中含表面活性物質較多時，易預先用泡沫分離法或其他方法去除。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)。自從1954年在荷蘭的首次投入使用以來。中國給水排水，2003，19(9)：45~47。 van Straten, G.
