The results indicates, with the same level of other parameters, the TN removal can reach 80.0% and 70.9% with the control of dissolved oxygen under the levels of 0.3-0.6mg/l and 0.6-0.9mg/l, respectively; the TN removal upgrades from 80%, 83% to 84.1% with the decrease of sludge load in the system from 0.1, 0.07, to 0.05gCOD/gMLSS·d; the nitrogen removal only reaches 58% when C/N is 4, but can reach more than 80% when C/N is at or over 7, which indicates that the TN removal increases when higher C/N ratio; when HRT increases from 12h, 18h to 24h, the TN removal also increases from 78.6%, 82.0% to 83.0%; the TN removal average in the system increases from 75.6%, 78.5% to 83.0% with the increase of sludge age from 18d, 20d to 24d; the low oxygen conditions in the modified Orbal oxidation ditch model do not decrease the effect of COD removal, and the dissolved oxygen gradient with the distribution of 0-2-1mg/l in the system ensures the COD removal reaching the range of 80%-86%; and the phosphate removal, however, is not good enough, which varies from 40% to 50%, even lower than 35% in occasional situations, and the phosphate concentration in the outflow varies in the range of 1.28-2.38mg/l, which dissatisfies the discharge standard with the level of 1.0mg/l.
试验结果表明,在其它参数相同的情况下,将外沟道的溶解氧分别控制在0.3~0.6mg/l 和0.6~0.9mg/l 两个水平,外沟道中TN 去除率分别为80.0%和70.9%;系统中污泥负荷分别为0.1gCOD/gMLSS·d、0.07 gCOD/gMLSS·d、0.05 gCOD/gMLSS·d时,随着污泥负荷的降低,TN 的去除率却是上升的,分别为80%、83%、84.1%;本试验中,当C/N 为4时,仅能获得58%的脱氮率,当C/N 为7 或更高时脱氮率能达到80%以上,进水C/N 比值越高,总氮的去除率越高;在本试验中采取的水力停留分别为12h、18h、24h 时,外沟道中的总氮去除率随水力停留时间的增加而增加,分别为78.6%、82.0%和83.0%;当系统泥龄分别为18d、20d、24d 时,系统平均TN 去除率分别为75.6%、78.5%、83.0%,随着泥龄的增大TN 的去除率增加;改良型奥贝尔模型的低氧条件并没有降低COD 的去除效果,系统0-2-1mg/l的溶解氧梯度分布使得COD 去除率一般都在80%~86%之间;本试验中磷的去除效果不好,去除率基本在40%~50%之间,有的甚至低于35%,出水磷的浓度在1.28~2.38mg/l 之间,低于1.0mg/l 的出水排放标准。
