| 摘 要： | 利用天然硅藻土在静态条件下对垃圾渗滤液中的氨氮和COD的吸附效果进行了研究。结果表明：天然硅藻土对于氨氮的去除效率只有14．1％；但对COD的去除效率可以达到70．1％；天然硅藻土对于COD的饱和吸附量和吸附速度明显高于其对氨氮的饱和吸附量及吸附速度；在平衡浓度相当高的情况下，每克硅藻土具有吸附65．31mg COD的极限潜力。

| Abstract: | The adsorption of COD and ammonia under the static condition were studied by using natural diatomite.The results show that the removal efficiency of ammonia is only 14.1 % while the COD removal efficiency can reach 70.1%.The adsorption amounts of COD was significantly higher than ammonia with the same to the adsorption speeds.Balance in a very high concentration,the absorption potential for COD can be 65.31mg per gram of diatomite. |
