The results show that the optimal value of CoCl2 concentration is 0.2 mol/L and the maximum adsorbed amount is 19.674 mg/g onto this adsorbent. The adsorption capacity of phosphine onto CoCl2-modified ACF decreases with the increase of temperatures. The maximum absorbed amounts are 19.674 mg/g at 298 K, 13.537 mg/g at 313 K and 11.087 mg/g at 328 K, respectively. It is found that the Freundlich equation is more suitable for the description of phosphine adsorption process than the Langmuir equation. The isosteric heat of adsorption decreases with the increase of the surface loading on CoCl2-modified ACF, which means that CoCl2-modified ACF adsorbent has an energetically heterogeneous surface. Meanwhile, adsorptive phosphine removal performance may be a dominant of physical adsorption when the heat of adsorption is 16-24 kJ/mol, the CoCl2-modified ACF adsorbent will be one of the candidates for tail gas purification of airtight calcium-carbide furnace and recycle of phosphine.

研究结果表明：浸渍液浓度最佳值为0.2 mol/L，此改性ACF对PH3的饱和吸附量为19.674 mg/g；PH3在CoCl2改性ACF上的吸附量随温度升高而迅速降低，在298，313和328 K时PH3的饱和吸附量分别为19.674，13.537和11.087 mg/g；Freundlich吸附等温方程较好地模拟了PH3在改性ACF上的等温吸附；PH3气体在改性ACF上的等量吸附热随吸附量的增大而减小，表明改性ACF吸附剂表面能量的不均匀性；吸附热在16~24 kJ/mol范围内，过程为物理吸附，有利于密闭电石炉尾气的净化。

Experimental results showed that, in this process, the optimal pH of the shortcut nitrification was 8.0～8.5; when the pH was less than 6,the nitrification is completely inhibited; when the pH was 6～7, at the end of aeration, the Nitrobacteria become the dominant bacteria because of the dropping of the free ammonia concentration. It is known to all, the activity of the Nitrobacteria and Nitrosomonas was affected by FA concentration, so nitrification was affected by FA concentration. According to the author's research results, the FA concentration which inhibit the Nitrobacteria was below 1.0mg/L,which inhibit the Nitrosomonas was above 10mg/L.
