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。

The research method is combining historic happening with scientific research.This paper is composed of seven chapters. The preface explains briefly the reason of choosing this topic and its significance, as well as the existent research situation in the academic circle.The first chapter presents the subjective and objective historical condition of the formation and development of his view about population quality in four aspects.The second chapter gives a full play to its evolution: it gestates and germinates before the failure of the revolution in 1911, takes shape and develops in the period of Base Area. The following period after the founding of People's Republic of China is its mature time. This view also experiences twisty developments in China's exploring period of socialism.The third part focuses on its major connotations, including Mao's narration on the connotation of Population quality, his analysis of contradiction between population quality and Chinese revolution and construction and of their significance, and the way to enhance Chinese population quality.The fourth chapter makes analyses of philosophical support of Mao's view from three "adherences": adherence to basic principle of seeking truth from facts;adherence to the common acknowledged fact that the people is the main part of history;adherence to the dialectical relation between being and consciousness.
