%X The nitrification ability of different layers in a subsurface constructed wetland treating sewage was measured. The experiment results showed that the ability of nitrification was decreased along the direction of water flow in the subsurface wetland. The constants of ammonia oxidation rate and nitrite oxidation rate in the slag layer on the bottom were 1.99-6.89 mg.(h.kg)-1 and 1.14-5.22 mg.(h.kg)-1 respectively, but in the soil layer on the top were 0.53-0.89 mg.(h.kg)-1 and 0.96-1.39 mg.(h.kg)-1 respectively. So the ability of nitrification in the layer of slag was better than the layer of soil obviously, and it showed that the nitrification was mainly happened in the slag layer.
