The contents of chlorophyll a in the water surface is between 7~21μg/l and the lower layer is under 5μg/l. The most dominant species of nannoplankton is Trachelomonas sp.

结果发现水库生态高度稳定，水质介於轻微到中度有机物污染，尚达不到优养化之地步，水表之叶绿素a的含量最多，但都在7~21μg/l之间，但中、下层很少不超过5μg/l。

But the effluent ammonium in the anoxic reactor, where enough NO2 were present, was equal to the blank system, and no ammonium was converted to such nitrogen compounds as NO2- and N2 by Nitrosomonas eutropha using NO2 as electron acceptor, which maybe caused by lack of the function bacteria. There were two ANAMMOX reaction pathways in the one-stage autotrophic nitrogen removal system. One way was that after part of NH4+ was oxidized to NH2OH under aerobic conditions, NH2OH and NO2- were converted to N2O under anaerobic conditions, at last N2O was further converted to N2 which realized the nitrogen removal; Another way was that at first NO2- was reduced to NH2OH, NH2OH reacted with NH4+ to form N2H4, which was further converted to N2 subsequently, realizing the nitrogen removal.

结果表明：单级自养脱氮系统内6.72%的氨氮是通过吹脱等物化作用去除的，不超过6.02%的氨氮是通过传统硝化反硝化途径去除的，87.26%左右的氨氮是由自养脱氮途径去除的，自养脱氮反应起主要脱氮作用；在足够NO2存在且缺氧的条件下，单级自养脱氮系统内的出水氨氮浓度与空白反应器相当，NH4+并没有被亚硝化单胞菌以NO2为电子受体氧化为NO2-和N2等化合物而得以去除，可能是因为系统内不存在该代谢功能的亚硝化功能菌；单级自养脱氮系统内存在两条ANAMMOX反应途径：其中一条途径即NH4+在好氧条件下被氧化为NH2OH后，生成的NH2OH与系统内的NO2-在缺氧条件下被转化为N2O，N2O则进一步被转化为N2而实现氮的去除；另外一条途径即NO2-首先被还原为NH2OH，生成的NH2OH则与系统内的NH4+反应生成N2H4，N2H4继续被转化为N2而实现氮的去除。
