The effects of the initial NH+4-N, DO and pH on the completely autotrophic nitrogen removal performance of the granular sludge were investigated in batch experiments.

采用间歇实验，考察了初始NH+4-N浓度、DO浓度和pH对颗粒污泥完全自营养脱氮的特性的影响。

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。
