And this strain degraded H〓S without lag time. The heterotrophic bacteria's generation period was short and its growth was rapid. The result of experiment indicated when the strain Hm-6 was applying to the packed tower, the startup was more quickly and the control was more convenient than the autotrophic bacterium. Applying to deodorize the H〓S, the better removalability could be got. At the same time, comparing with the system used at home of which the biofilm directly formed with activated sludge, it runs in the neutral condition, has lower corrusivity to the equipment and was liable to handle. And this system didn't need the acclimation to become biofilm, so it can save a rather long acclimation time.

异养菌虽然不以硫化物作为能源物质，但其世代周期短、生长迅速，运行管理比自养菌更为方便，具有周期短，启动迅速等优点，接种了菌株Hm-6泥炭生物填料塔，对低浓度H〓S有较高的去除效果，且没有延迟期，与国内通常采用的直接以活性污泥挂膜的方式相比，应用该菌的脱臭系统在中性条件下运行，对设备的腐蚀性较低、运行过程较易控制，具有很好的应用前景。

The number of autoterophic bacteria were significantly lower than the heterotrophic bacteria. Majority of 21 strains of heterotrophic bacteria that isolated from water body were Pseudomonas. Majority of 25 strains of heterotrophic bacteria isolated from sediment were bacillus, microccus and Pseudomonas.Three genus of autotrophic bacteria were sulphuret bacteria, nitrify bacteria and nitrosobacteria that were capable of oxidizing H2S, S, FeS, oxidizing NH3 to NO2 and NO2 to NO3 respectively.

试验稚鳖池水中共分离出21株异养细菌，其中优势菌为假单胞杆菌属细菌；底泥中共分离出25株异养细菌，其中优势菌为芽胞杆菌属细菌，微球菌属细菌假单胞菌属细菌，三种自养细菌分别为具有氧化硫化氢、元素硫或硫化亚铁的硫细菌；具有氧化氨为亚硝酸的亚硝化细菌和能将亚硝酸进一步转化成硝酸的硝化细菌。

Microbiological community analysis identified two strains similar to Nitrosomonas eutropha were responsible for oxygen consumption,which were able to exist in the autotrophic anaerobic condition for long periods and protect Planctomycetes sp.from the influence of oxygen.

分子生物学实验分析发现两株和Nitrosomonas eutropha(AY123795)序列相似性高达99%的细菌存在于反应器中，其在有氧条件下能转变其代谢模式好氧生长，从而保证Planctomycetes sp。代谢所必须的厌氧条件。

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。

In this paper, the biological and organic geochemical methods were applied together to study the characteristics of thermal simulant products of calcifiied and noncalcified coccolithophore, fresh and dead Pediastrum boryanum, autotrophic and heterotrophic Chlorella protothecoides, as well as Synechocystis.
